Description

P/001011 Regulation 3.2 AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Invention Title: Compounds for the treatment of addiction The following statement is a full description of this invention, including the best method of performing it known to us: COMPOUNDS FOR THE TREATMENT OF ADDICTION CROSS-REFERENCE TO OTHER APPLICATIONS [0001] This application is a divisional of Australian patent application no. 2012279332, the entire disclosure of which is incorporated herein by reference. FIELD [0001a] The present disclosure relates to novel human mitochondrial aldehyde dehydrogenase (ALDH-2) inhibitors and their use in treating mammals for their dependence upon drags of addiction, such as an addiction to dopamine-producing agents like cocaine, opiates, amphetamines, nicotine, and alcohol. The disclosure further relates to methods for the use of such compounds, and to pharmaceutical compositions containing them. BACKGROUND [0002] Today, dependence upon drugs of addiction causes major health problems worldwide. For example, alcohol abuse and alcohol dependency can cause liver, pancreatic and kidney disease, heart disease, including dilated cardiomyopathy, polyneuropathy, internal bleeding, brain deterioration, alcohol poisoning, increased incidence of many types of cancer, insomnia, depression, anxiety, and even suicide. Heavy alcohol consumption by a pregnant mother can also lead to fetal alcohol syndrome, which is an incurable condition. Additionally, alcohol abuse and alcohol dependence are major contributing factors for head injuries, motor vehicle accidents, violence and assaults, and other neurological and other medical problems. [00031 Addiction to nicotine is estimated by the National Institute on Drug Abuse to kill nearly 500,000 Americans every year. This total represents about 1 in 6 of all deaths in the U.S. caused by any means, and is more than the total of deaths caused by use of alcohol, cocaine, heroin, suicide, car accidents, fire and AIDS combined. Cigarette smoking is the most popular method of using nicotine, but there are also smokeless tobacco products such as snuff and chewing tobacco. [0004] Nicotine addiction is linked to disease states such as leukemia, cataracts, and pneumonia; it is the cause of about one-third of all cancer deaths, the foremost of which is lung cancer. In addition to cancer, cigarette smoking also causes lung diseases, such as bronchitis and emphysema; it exacerbates asthma symptoms, and is the cause of chronic obstructive pulmonary diseases in general. It is also well known that cigarette smoking increases the risk of cardiovascular diseases, including stroke, heart attack, vascular disease, aneurysm, and the like. [0005] Another major health problem is caused by cocaine abuse. Physical effects of cocaine use include constricted blood vessels, dilated pupils, and increased temperature, heart rate, and blood pressure. A user of cocaine can experience acute cardiovascular or cerebrovascular emergencies, such as a heart attack or stroke, potentially resulting in sudden death. Other complications associated with cocaine use include disturbances in heart rhythm, chest pain and respiratory failure, seizures, headaches, and gastrointestinal complications such as abdominal pain and nausea. Because cocaine has a tendency to decrease appetite, many chronic users can become malnourished. Repeated use of cocaine may lead to a state of increasing irritability, restlessness, and paranoia. This can result in a period of full-blown paranoid psychosis, in which the user loses touch with reality and experiences auditory hallucinations. Moreover, it is well known that the concurrent abuse of nicotine, cocaine and alcohol is common. It has been found that the combination of cocaine and alcohol exerts more cardiovascular toxicity in humans than either drug alone. [0006] Historically, treating chemical dependence largely involved attempts to persuade patients to discontinue use the substance voluntarily (behavioral therapy). However, cocaine, morphine, amphetamines, nicotine, and alcohol, and other types of dopamine-producing agents are highly addictive substances, and dependence upon such drugs can be harder to break and is significantly more damaging than dependence on most other addictive substances. In particular, alcohol, cocaine, and heroin dependence are typically chronic relapsing disorder , [0007] There has been some moderate success in providing effective treatments for tobacco addiction by the use of nicotine replacement therapy, such as nicotine gum or the nicotine transdermal patch. Additionally, antidepressants and antihypertensive drugs have been tried, with modest success. Attempts have also been made to treat tobacco addiction by persuading patients to discontinue the use of tobacco voluntarily (behavioral therapy), but this method has not proved to be very successful. Accordingly, it is clearly desirable to find a treatment for tobacco addiction that reduces or prevents the craving for nicotine that does not involve nicotine replacement therapy or the use of antidepressants and antihypertensive drugs. [00081 Accordingly, there has been much interest in the scientific community in attempting to find substances that could be employed to ameliorate dependency on addictive agents. 2 Compounds that have previously been employed for the treatment of alcohol abuse include disulfiram (AntabuseTM), cyanamide, naltrexone; and acamprosate.

The drug, however, is hepatotoxic and causes side-effects that often require medical intervention. Acamprosate, another approved drug, is thought to act by modulating glutamatergic systems. It only has moderate efficacy and serious side effects that include diarrhea, allergic reactions, irregular heartbeats, and low or high blood pressure. Disulfiram, an aldehyde dehydrogenase inhibitor, acts by interfering with the metabolic pathway of alcohol. Normally, alcohol is metabolized to acetaldehyde, which in turn is eliminated by oxidation to acetic acid by the enzyme aldehyde dehydrogenase. Disulfiram inhibits aldehyde dehydrogenase and thereby prevents oxidation of alcohol-generated acetaldehyde to acetic acid. Alcohol consumption during disulfiram treatment, however, leads to the accumulation of acetaldehyde, inducing unpleasant side-effects. Because disulfiram does not reduce craving for alcohol, success with the drug depends on a high level of patient motivation since patients who wish to drink can simply stop taking the drug. Additionally, it has been recently proposed that disulfiram can be used for the treatment of cocaine dependency (for example, see Bonet et al., Journal ofSubstance Abuse Treatment, 26 (2004), 225-232). [0010] Recently it has been shown that an isoflavone known as daidzein and structurally related derivatives thereof are effective in suppressing ethanol intake. Daidzein is the major active component obtained from extracts of Radix puerariae, a traditional Chinese medication that suppresses ethanol intake in Syrian golden hamsters. See Keung, W. M. and Vallee, B. L. (1993) Proc. Nati. Acad. Sci. USA 90,10008-10012 and Keung, W. M., Klyosov, A. A., and Vallee, B. L. (1997) Proc. Nati. Acad. Sci. USA 94, 1675-1679, and U.S. 3 Patents 5,624,910 and 6,121,010. U.S. Patents 5,624,910 and 6,121,010 disclosed ether isoflavone derivatives of daidzein, which were shown to be effective in treating ethanol dependency. [0011] Mechanistically, daidzein and its derivatives were shown to be potent and selective inhibitors of human mitochondrial aldehyde dehydrogenase (ALDH-2), which is an enzyme involved in the major enzymatic pathway responsible for-ethanol metabolism in humans. It appears preferable that daidzein analogues inhibit ALDH-2 selectively relative to the monoamine oxidase (MAO) pathway because daidzein analogues that inhibit both ALDH-2 and MAO exhibited less antidipsotropic activity. Alternatively, WO 2008/014497 disclosed novel isoflavone derivatives that are selective ALDH-2 inhibitors with little effect on the MAO pathway and, thus, are useful for the treatment of alcohol dependency. [00121 In view of the above-indicated discoveries, a demand has emerged for additional classes of compounds that are safe and effective for the treatment of alcohol dependency, but that are structurally distinct from disulfiram, cyanamide, naltrexone; acamprosate, daidzein, and analogs thereof Ideally, such additional classes of compounds will also be useful for the treatment of other addictive agents such as cocaine, heroin, and nicotine, and in particular, ameliorate the tendency of abusers to relapse. SUMMARY [0013] Surprisingly, it has now been discovered that compounds of Formula (I) as described below, although structurally unrelated to known compounds for the treatment of addictive agents, are nonetheless effective for the treatment of alcohol dependency as determined from the model studies also described herein. Further, the compounds of Formula (I) are effective in the treatment of other addictive agents such as cocaine, heroin, and nicotine. In particular, the compounds of Formula (I) ameliorate the tendency of abusers to relapse. In certain aspects, the compounds of Formula (I) inhibit ALDH-2 selectively relative to the monoamine oxidase (MAO) pathway. [0014] Accordingly, in certain aspects, is provided compounds of Formula (I): 4

[0082] Where a given group (moiety) is described herein as being attached to a second group and the site of attachment is not explicit, the given group may be attached at any available site of the given group to any available site of the second group. For example, a "lower alkyl-substituted phenyl", where the attachment sites are not explicit, may have any available site of the lower alkyl group attached to any available site of the phenyl group. In this regard, an "available site" is a site of the group at which a hydrogen of the group may be replaced with a substituent. [0083] A compound of a given Formula (e.g. the "compound of Formula (I)") is intended to encompass the compounds of the disclosure, and the pharmaceutically acceptable salts, pharmaceutically acceptable esters, hydrates, polymorphs, and prodrugs of such compounds. Additionally, the compounds of the disclosure may possess one or more asymmetric centers, and can be produced as a racemic mixture or as individual enantiomers or diastereoisomers. The number of stereoisomers present in any given compound of a given Formula depends upon the number of asymmetric centers present (there are 2" stereoisomers possible where n is the number of asymmetric centers). The individual stereoisomers may be obtained by resolving a racemic or non-racemic mixture of an intermediate at some appropriate stage of the synthesis, or by resolution of the compound by conventional means. The individual stereoisomers (including individual enantiomers and diastereoisomers) as well as racemic and 20 non-racemic mixtures of stereoisomers are encompassed within the scope of the present invention, all of which are intended to be depicted by the structures of this specification unless otherwise specifically indicated. [0084] "Isomers" are different compounds that have the same molecular formula. Isomers include stereoisomers, enantiomers, and diastereomers. [0085] "Stereoisomers" are isomers that differ only in the way the atoms are arranged in space. [0086] "Enantiomers" are a pair of stereoisomers that are non-superimposable mirror images of each other. A 1:1 mixture of a pair of enantiomers is a "racemic" mixture. The term "(±)" is used to designate a racemic mixture where appropriate. [0087] "Diastereoisomers" are stereoisomers that have at least two asymmetric atoms, but which are not mirror-images of each other. [0088] The absolute stereochemistry is specified according to the Cahn Ingold Prelog R S system. When the compound is a pure enantiomer the stereochemistry at each chiral carbon may be specified by either R or S. Resolved compounds whose absolute configuration is unknown are designated (+) or (-) depending on the direction (dextro- or laevorotary) that they rotate the plane of polarized light at the wavelength of the sodium D line. [0089] Some of the compounds exist as tautomeric isomers. Tautomeric isomers are in equilibrium with one another. For example, amide containing compounds may exist in equilibrium with imidic acid tautomers. Regardless of which tautomer is shown, and regardless of the nature of the equilibrium among tautomers, the compounds are understood by one of ordinary skill in the art to comprise both amide and imidic acid tautomers. Thus, the amide containing compounds are understood to include their imidic acid tautomers. Likewise, the imidic acid containing compounds are understood to include their amide tautomers. Non-limiting examples of amide-comprising and imidic acid-comprising tautomers are shown below: 2 N H 2 N 0 OH [0090] The term "therapeutically effective amount" refers to an amount that is sufficient to effect treatment, as defined below, when administered to a mammal in need of such treatment. The therapeutically effective amount will vary depending upon the subject and 21 disease condition being treated, the weight and age of the subject, the severity of the disease condition, the manner of administration and the like, which can readily be determined by one of ordinary skill in the art. [0091] The term "polymorph" refers to different crystal structures of a crystalline compound. The different polymorphs may result from differences in crystal packing (packing polymorphism) or differences in packing between different conformers of the same molecule (conformational polymorphism). [0092] The term "solvate" refers to a complex formed by the combining of a compound of Formula (I) and a solvent. [00931 The term "hydrate" refers to the complex formed by the combining of a compound of Formula (I) and water.

[0095] Any formula or structure given herein, including Formula (I) compounds, is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine, and chlorine, such as, but not limited to 2H (deuterium, D), 3 H (tritium), 11 C, 1 3 C, 1 4 C, 15 N, 1 8F, 31 P, 32 P, 35 s, 36 C1, and 1251. Various isotopically labeled compounds of the present invention, for example those into which radioactive isotopes such as 3 H, "C, and 1 4 C are incorporated. Such isotopically labelled compounds may be useful in metabolic studies, reaction kinetic studies, detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays, or in radioactive treatment of patients. [0096] Deuterium labelled or substituted therapeutic compounds of the invention may have improved DMPK (drug metabolism and pharmacokinetics) properties, relating to distribution, metabolism, and excretion (ADME). Substitution with heavier isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for 22 example increased in vivo half-life or reduced dosage requirements. An 18F labeled compound may be useful for PET or SPECT studies. Isotopically labeled compounds of this invention and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent. Further, substitution with heavier isotopes, particularly deuterium (i.e., 2H or D) may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements or an improvement in therapeutic index. It is understood that deuterium in this context is regarded as a substituent in the compound of the Formula (I). [00971 The concentration of such a heavier isotope, specifically deuterium, may be defined by an isotopic enrichment factor. In the compounds of this invention any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise stated, when a position is designated specifically as "H" or "hydrogen", the position is understood to have hydrogen at its natural abundance isotopic composition. Accordingly, in the compounds of this. invention any atom specifically designated as a deuterium (D) is meant to represent deuterium. [0098] The term "treatment" or "treating" means any administration of a compound of the invention to a mammal having a disease or susceptible to a disease for purposes including: (i) preventing the disease, that is, causing the clinical symptoms of the disease not to develop; (ii) inhibiting the disease, that is, arresting the development of clinical symptoms; and/or (iii) relieving the disease, i.e. causing the regression of clinical symptoms.

Supplementary active ingredients can also be incorporated into the compositions. [0104] Where a given group (moiety) is described herein as being attached to a second group and the site of attachment is not explicit, the given group may be attached at any available site of the given group to any available site of the second group. For example, a "lower alkyl-substituted phenyl", where the attachment sites are not explicit, may have any available site of the lower alkyl group attached to any available site of the phenyl group. In this regard, an "available site" is a site of the group at which a hydrogen of the group may be replaced with a substituent. [0105] It is understood that in all substituted groups defined above, polymers arrived at by defining substituents with further substituents to themselves (e.g., substituted aryl having a substituted aryl group as a substituent which is itself substituted with a substituted aryl group, etc.) are not intended for inclusion herein. Also not included are infinite numbers of substituents, whether the substituents are the same or different. In such cases, the maximum number of such substituents is three. Each of the above definitions is thus constrained by a limitation that, for example, substituted aryl groups are limited to -substituted aryl (substituted aryl)-substituted aryl.

Synthesis of the Compounds of Formula (1) [01191 Compound Preparation: The compounds can be prepared from readily available starting materials using, for example, the following general methods and procedures. It will be appreciated that where typical or preferred process conditions (i.e., reaction temperatures, times, mole ratios of reactants, solvents, pressures, etc.) are given, other process conditions 30 can also be used unless otherwise stated. Optimum reaction conditions may vary with the particular reactants or solvent used, but such conditions can be determined by one skilled in the art by routine optimization procedures [0120] Additionally, as will be apparent to those skilled in the art, conventional protecting groups may be necessary to prevent certain functional groups from undergoing undesired reactions. The term "protecting group" or "PG," as used herein, is meant that a particular functional moiety, e.g., 0, S, or N, is temporarily blocked so that a reaction can be carried out selectively at another reactive site in a multifunctional compound. "Protecting groups" or "PGs,"as used herein, are well known in the art and include those described in detail in Protective Groups in Organic Synthesis, Fourth Ed., Greene, T.W. and Wuts, P.G., Eds., John Wiley & Sons, New York: 2007, the entire contents of which are hereby incorporated by reference, and references cited therein. [01211 The term "protecting group" or "PG" encompasses a "suitable amino protecting group" that is well known in the art and includes those described in detail in Greene et al. Non-limiting examples of suitable amino protecting groups include methyl carbamate, ethyl carbamate, 9-fluorenylmethyl carbamate (Fmoc), t-butyl carbamate (BOC), and benzyl carbamate (Cbz). [0122] The term "protecting group" or "PG" further encompasses a "suitable carboxylic acid protecting group" and a "suitable phosphoric acid protecting group" that is well known in the art and includes those described in detail in Greene et al. Non-limiting examples of suitable carboxylic acid protecting groups and suitable phosphoric acid protecting groups further include, but are not limited to, silyl-, alkyl-, alkenyl-, aryl-, and arylalkyl- protecting groups. [0123] The term "protecting group" or "PG" further encompasses a "suitable hydroxyl protecting group," that is well known in the art and includes those described in detail in Greene et al. Non-limiting examples of suitable hydroxyl protecting groups include methyl, t-butyl, methoxylmethyl (MOM), trimethylsilyl (TMS), triethylsilyl (TES), triisopropylsilyl (TIPS), and the like. [0124] The term "leaving group" or "LG" as used herein, is well known among those of skill in the art as a labile substituent of a compound that is readily displaced from the compound. Leaving groups, as used herein, are described in March's Advanced Organic Chemistry, (John Wiley, and Sons, 5 h Edition, 2001), and encompass the group consisting of 31 a halo; ORG; SRG; O(CO)RG; S(CO)Ro; O(SO 2 )RG; OP(O)ORGORH; or N2*; wherein each RG and R is, independently, hydrogen, a substituted or unsubstituted, branched or unbranched, cyclic or acyclic C1.10 alkyl; a substituted or unsubstituted, branched or unbranched, cyclic or acyclic C-o haloalkyl; a substituted or unsubstituted aryl; or a substituted or unsubstituted haloaryl.

[0125] The term "peptide coupling agent" refers to reagents used in the methods of peptide coupling that are well known to those skilled in the art as described in M. Bodansky, et a[., "The Practice of Peptide Synthesis, Reactivity and Structure, Concepts in Organic Chemistry, " Volume 21, Second, Revised Edition, Springer-Verlag, New York, N.Y. (1994), the entire contents of which are hereby incorporated by reference. The "peptide coupling agents," as used herein, that are useful in the method include, but are not limited to those disclosed in Bodansky, et al., such as O-(7-azabenzotriazol-1-yl) -NN,N',N'-tetramethyluronium hexafluorophosphate (HATU), O-benzotriazole -N,N,N',N'-tetramethyl-uronium-hexafluoro-phosphate (HBTU), dicyclohexyl carbodiimide (DCC), diisopropyl carbodiimide (DIC). DCC/1-hydroxy benzotriazole, DCC/NV hydroxysuccinimide, I -ethyl-3-(3-dimethyllaminopropyl) carbodiimide hydrochloride EDC HCl, 1-isobutoxycarbonyl-2-isobutoxy-1,2-dihydro quinone (IIDQ), carbonyldiimidizole, N-ethyl-5-phenylisoxazolium-3'-sulfonate (Woodward's Reagent K), benzotriazolyl-N-hydroxytris(dimethyamino)phosphonium hexafluorophosphate (BOP), (benzotriazol-1 -yloxy)tripyrrolidinophosphonium hexafluorophosphate (PyBOP), and the like. [0126) The term "Suzuki reaction" as used herein, is well known among those of skill in the art as and refers to a CC coupling of two reactants in which one reactant is a boronic acid or 32 boronic ester moiety, as described by N. Miyaura and A. Suzuki; Chem. Rev.; 1995, 95, 2457-2483; and A. Suzuki, J. Organomet. Chem., 1999, 576, 147-168. Typically, the Suzuki reaction may be carried out in the presence of a palladium catalyst such as palladium(II) acetate, tetrakis(triphenylphosphine)palladium (0), palladium on activated charcoal or dichloro[ 1,1 '-bis(diphenylphosphino)ferrocene]palladium(II), in an aprotic polar solvent (for example acetonitrile, NN-dimethylformamide, dimethoxyethone or tetrahydrofuran) or a protic polar solvent (for example n-propanol, iso-propanol) or a mixture of these solvents with water. The volume of solvent used will be from approximately 3 to 30 times the quantity of boronic acid or boronic ester used. Advantageously, the palladium catalyst may contain a ligand selected from: a triphenylphosphine, a tri-o-tolylphosphine, a tri-m-tolylphosphine or a tri-p-tolylphosphine. The catalysts particularly preferred are palladium(II) acetate and palladium on carbon which make it possible to obtain particularly fast reaction kinetics. Palladium(H) acetate may be advantageously used in combination with a 2-(dicyclo hexylphosphino)biphenyl type ligand (J. P. Wolfe et al., J. Am. Chem. Soc., 1999,121, 9550 9561). The reaction is generally carried out in the presence of an inorganic base such as potassium carbonate, sodium carbonate, caesium carbonate, sodium hydroxide or potassium hydroxide or in the presence of a tertiary amine such as triethylamine or diisopropylethylamine. In certain embodiments the inorganic base can be potassium carbonate or potassium hydroxide. The Suzuki reaction is preferably carried out under an inert atmosphere, for example, under an argon or nitrogen atmosphere. The reaction mixture is advantageously heated at a temperature in the range from 60 'C to 110 *C, for 2 minutes to 24 hours. Quenching with an acidic medium, for example, in the presence of HC1, is often carried out. One skilled in the art will be able to modify these conditions, in particular by applying the variants of the Suzuki reaction which are described in the literature. [0127] The term "cyclic boronic ester moiety" refers to portions of boron-comprising reactants used in Suzuki reactions such as 4,4,5,5-tetramethyl-1,3,2-dioxa boronic ester, 4,4,5,5-tetramethyl-1,3,2-dioxaboronic ester, pinacolato dioxaboronic ester, catechol dioxaboronic ester, neopentyl glycolato dioxaboronic ester, hexylene glycolato dioxaboronic ester, [(+)-pinonediolato] dioxaboronic ester, [(-)-pinonediolato] dioxaboronic ester, diethyl d-tartrate glycolato dioxaboronic ester, diethyl-l-tartrate glycolato dioxaboronic ester, diisopropyl-d-tartrate glycolato dioxaboronic ester, diisopropyl-l-tartrate-glycolato dioxaboronic ester, N,N,N' ,N' -tetramethyl-d-tartaramide 33 -glycolato dioxaboronic ester, or N,N,N',N'-tetramethyl- -tartaramide glycolato dioxaboronic ester. [01281 Furthermore, the compounds may contain one or more chiral centers. Accordingly, if desired, such compounds can be prepared or isolated as pure stereoisomers, i.e., as individual enantiomers or diastereomers, or as stereoisomer-enriched mixtures. All such stereoisomers (and enriched mixtures) are included within the scope, unless otherwise indicated. Pure stereoisomers (or enriched mixtures) may be prepared using, for example, optically active starting materials or stereoselective reagents well-known in the art. Alternatively, racemic mixtures of such compounds can. be separated using, for example, chiral column chromatography, chiral resolving agents, and the like. [01291 The starting materials for the following reactions are generally known compounds or can be prepared by known procedures or obvious modifications thereof. For example, many of the starting materials are available from commercial suppliers such as Aldrich Chemical Co. (Milwaukee, Wisconsin, USA), Bachem (Torrance, California, USA), Emka Chemce or Sigma (St. Louis, Missouri, USA). Others may be prepared by procedures, or obvious modifications thereof, described in standard reference texts such as Fieser and Fieser's Reagentsfor Organic Synthesis, Volumes 1-15 (John Wiley, and Sons, 1991), Rodd's Chemistry of Carbon Compounds, Volumes 1-5, and Supplementals (Elsevier Science Publishers, 1989), Organic Reactions, Volumes 1-40 (John Wiley, and Sons, 1991), March's Advanced Organic Chemistry, (John Wiley, and Sons, 5* Edition, 2001), and Larock's Comprehensive Organic Transformations (VCH Publishers Inc., 1989). [0130] The terms "solvent", "inert organic solvent" or "inert solvent" mean a solvent inert under the conditions of the reaction being described in conjunction therewith [including, for example, benzene, toluene, acetonitrile, tetrahydrofuran ("THF"), dimethylformamide ("DMF"), chloroform, methylene chloride (or dichloromethone), diethyl ether, methanol, pyridine and the like]. Unless specified to the contrary, the solvents used in the reactions are inert organic solvents. [0131] The term "q.s." means adding a quantity sufficient to achieve a stated function, e.g., to bring a solution to the desired volume (i.e., 100%). Synthetic Strategies [01321 The compounds of Formula (I) in which substituents R' through R 2 7 , XI, Yl, ZI and Z2 are as defined herein. LG is a leaving group (e.g.,-halo, hydroxyl, alkoxy, OS0 2

[0144] The compounds of Formula (I) are usually administered in the form of pharmaceutical compositions. Therefore, pharmaceutical compositions are provided that contain, as the active ingredient, one or more of the compounds of Formula (I), or a pharmaceutically acceptable salt or ester thereof, and one or more pharmaceutically acceptable excipients, carriers, including inert solid diluents and fillers, diluents, including 42 sterile aqueous solution and various organic solvents, permeation enhancers, solubilizers and adjuvants. [0145] The compounds of Formula (I) may be administered alone or in combination with other therapeutic agents. Such compositions are prepared in a manner well known in the pharmaceutical art (see, e.g., Remington's Pharmaceutical Sciences, Mace Publishing Co., Philadelphia, PA 17'h Ed. (1985) and Modern Pharmaceutics, Marcel Dekker, Inc. 3 d Ed. (G.S. Banker & C.T. Rhodes, Eds.). Methods of Use [01461 In certain aspects, methods of using the compounds of Formula (I) in the treatment of addiction to a dopamine-producing agent are provided. The method comprises administering to a mammal in need thereof a therapeutically effective dose of a compound of Formula (I). Such diseases include, but are not limited to, the treatment of dependency upon cocaine, opiates, amphetamines, nicotine, and alcohol. In certain embodiments, the compounds of Formula (I) are generally effective in the treatment of conditions that respond to the administration of ALDH-2 inhibitors. While not wishing to be bound by theory, it is believed that the compounds described herein are effective in treating addiction as a consequence of their ability to normalize the increased dopamine levels associated with various addictive behaviors. See, N.D. Volkow et al., Dopamine in drug abuse and addiction: results from imaging studies and treatment implications, Mol. Psychiatry 9 (2004), pp. 557 569; and B.J. Everitt and M.E. Wolf, Psychomotor stimulant addiction: a neural systems perspective, J. Neurosci. 22 (2002), pp. 3312-3320. Addictive behavior has been shown to include addiction to food particularly sugary foods. For example, in the manuscript "Evidence for sugar addiction: Behavioral and neurochemical effects of intermittent, excessive sugar intake" (Hoebel et. Al. Neurosci Biobehav Rev. 2008 ; 32(1): 20-3 9.), the authors wrote "What this review demonstrates is that rats with intermittent access to food and a sugar solution can show both a constellation of behaviors and parallel brain changes that are characteristic of rats that voluntarily self-administer addictive drugs. In the aggregate, this is evidence that sugar can be addictive." [0147] Given this proposed mechanism of action, the compounds of Formula (I) are useful, for example, in the treatment of addictive and compulsive behaviors and neurological conditions associated with increased dopamine levels as described, for example, in the 43 published U.S. patent application 20100113483. Such behaviors and conditions include, but are not limited to, compulsive gambling, overeating, and shopping, obsessive compulsive disorder (OCD), schizophrenia, attention deficit hyperactivity disorder, anxiety and the like.. In certain embodiments, the compounds described herein have also been shown to be effective in treating compulsive eating disorders and obesity. 10148] Another aspect pertains to methods of modulating (e.g., reducing) alcohol consumption, alcohol dependence and/or alcohol abuse for therapeutic purposes. Accordingly, in an exemplary embodiment, the modulatory method involves contacting ALDH-2 with a compound that inhibits ALDH-2. In yet another exemplary embodiment, the modulatory method involves administering a compound that increases the concentration of an aldehyde (e.g., 5-HIAL and/or DOPAL) formed during catabolism of a neurotransmitter (e.g., 5-HT/serotonin and/or DA/dopamine). Preferably, the compound does not inhibit MAO, or inhibits MAO only to a small degree. [0149] Another embodiment involves a method of modulating alcohol consumption for the treatment of alcohol abuse or dependence which includes the step of administering to a patient a therapeutically effective amount of a compound which inhibits ALDH-2, and/or increases the concentration of an aldehyde (e.g., 5-HIAL and/or DOPAL) formed during catabolism of a neurotransmitter (e.g., 5-HT and/or DA). [0150] In certain embodiments, is provided a method of modulating alcohol consumption in a mammal comprising administering a compound of Formula (1), or a pharmaceutical composition thereof, in an amount effective to increase a concentration of an aldehyde formed during catabolism of a neurotransmitter. In certain embodiments, the neurotransmitter is serotonin or dopamine. In certain embodiments, the aldehyde is 5-hydroxyindoleacetaldehyde or 3,4-dihydroxyphenylacetaldehyde. In certain embodiments, the compound does not inhibit monoamine oxidase. Testing [0151] Activity testing is conducted as described in those patents and patent applications referenced above, and in the Examples below, and by methods apparent to one skilled in the art. For example, as described in "The Mitochondrial Monoamine Oxidase-Aldehyde Dehydrogenase Pathway: A Potential Site of Action of Daidzein", J. Med. Chem. 2000, 43, 4169-4179. In general, the compounds of Formula (I) are assayed to determine their effects on MAO and ALDH-2 independently using the membrane and lysate of a density-gradient 44 purified mitochondria preparation as the respective enzyme sources. The results are expressed in IC 5 0 values. [01521 Monitoring the influence of a compound of Formula (I) on the modulation of alcohol consumption, dependence and/or abuse in a patient can be determined by a screening assay as described herein and as described, for example, in the published U.S. patent application 20040068003. In such an assay, decreased consumption of alcohol can be used to measure the effectiveness of compounds of Formula (I). [01531 For example, and not by way of limitation, ALDH-2 activity is decreased in cells treated with a compound of Formula (I) which inhibits ALDH-2 and as a consequence diverts part of 5-HT metabolic flux from the oxidative pathway, which leads to the formation of 5 hydroxyindoleacetic acid (5-HIAA), to the reductive pathway, further leading to the formation of 5-hydroxytryptophol (5-HTOL). Thus, to study the effect of a compound of Formula (I) on alcohol dependence and/or abuse, for example, in a clinical trial, urine samples can be collected and levels of 5-HIAA and 5-HTOL in the samples can be determined. Decreased levels of 5-HIAA and increased levels of 5-HTOL will indicate inhibition of ALDH-2 activity. In this way, the urine [5-HTOL]/[5-HIAA] ratio can serve as a marker, indicative of the physiological response of the cells to the compound. Accordingly, this response state may be determined before, and at various points during treatment of the individual with the compound. [01541 In one embodiment, is provided a method for monitoring the effectiveness of treatment of a subject with a compound of Formula (I) including the steps of (i) obtaining pre-administration urine samples from a subject before and after alcohol detoxification but prior to administration of the compound of Formula (I); (ii) determining the [5-HTOL]/[5 HIAA] ratios in the pre-administration samples; (iii) obtaining one or more post administration samples from the subject; (iv) determining the [5-HTOL]/[5-HIAA] ratio in the post-administration samples; (v) comparing the [5-HTOL]/[5-HIAA] ratios in the pre administration samples with that in the post administration sample or samples; and (vi) altering the administration of the compound of Formula (I) to the subject accordingly. According to such an embodiment, ALDH-2 inactivation and/or an increase in urine [5 HTOL]/[5-HIAA] ratio may be used as an indicator of the effectiveness of the compound of Formula (I), even in the absence of an observable phenotypic response. 45 Administration [0155] The compounds of Formula (I) are usually administered in the form of pharmaceutical compositions. Therefore provided herein are pharmaceutical compositions that contain, as. the active ingredient, one or more of the compounds of Formula (I), or a pharmaceutically acceptable salt or ester thereof, and one or more pharmaceutically acceptable excipients, carriers, including inert solid diluents and fillers, diluents, including sterile aqueous solution and various organic solvents, permeation enhancers, solubilizers and adjuvants. The compounds of Formula I may be administered alone or in combination with other therapeutic agents. Such compositions are prepared in a manner well known in the pharmaceutical art (see, e.g., Remington's Pharmaceutical Sciences, Mace Publishing Co., Philadelphia, PA 17* Ed. (1985) and "Modern Pharmaceutics", Marcel Dekker, Inc. 3 rd Ed. (G.S. Banker & C.T. Rhodes, Eds.). [0156] The compounds of Formula (I) may be administered in either single or multiple doses by any of the accepted modes. of administration of agents having similar utilities, for example as described in those patents and patent applications incorporated by reference, including rectal, buccal, intranasal and transdermal routes, by intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously, orally, topically, as an inhalant, or via an impregnated or coated device such as a stent, for example, or an artery-inserted cylindrical polymer. [0157] One mode for administration is parental, particularly by injection. The forms in which the novel compositions may be incorporated for administration by injection include aqueous or oil suspensions, or emulsions, with sesame oil, corn oil, cottonseed oil, or peanut oil, as well as elixirs, mannitol, dextrose, or a sterile aqueous solution, and similar pharmaceutical vehicles. Aqueous solutions in saline are also conventionally used for injection. Ethanol, glycerol, propylene glycol, liquid polyethylene glycol, and the like (and suitable mixtures thereof), cyclodextrin derivatives, and vegetable oils may also be employed. The proper fluidity can be maintained, for example, by the use of a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. 46 [01581 Sterile injectable solutions are prepared by incorporating the compound of Formula (I) in the required amount in the appropriate solvent with various other ingredients as enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various stedlized active ingredients into a sterile vehicle which contains the basic dispersion medium. and the required other ingredients from-those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the known methods of preparation include vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof. [0159] Oral administration is another route for administration of the compounds of Formula (I). Administration may be via capsule or enteric coated tablets, or the like. In making the pharmaceutical compositions that include at least one compound of Formula (I), the active ingredient is usually diluted by an excipient and/or enclosed within such a carrier that can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material (as above), which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, sterile injectable solutions, and sterile packaged powders. [0160] Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as tale, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. [0161] The compositions can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art. Controlled release drug delivery systems for oral administration include osmotic pump systems and dissolutional systems containing polymer-coated reservoirs or drug-polymer matrix formulations. Examples of controlled release systems are given in-U.S. Patent Nos. 3,845,770; 4,326,525; 4,902514; and 5,616,345. Another formulation for use in 47 the methods employs transdermal delivery devices ("patches"). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S. Patent Nos. 5,023,252, 4,992,445 and 5,001,139. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents. [01621 The compositions are preferably formulated in a unit dosage form. The term "unit dosage forms" refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient (e.g., a tablet, capsule, or ampoule). The compounds of Formula (I) are effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. Preferably, for oral administration, each dosage unit contains from about 10 mg to 1 g of a compound of Formula (I), more preferably from 1-0 to700 mg, and for parenteral administration, preferably from 10 to 700 mg of a compound of Formula (I), more preferably about 50-300 mg. Preferred dose regimens may also include administering about 100-300 mg twice daily to a patient in need thereof. Nonetheless, it will be understood, that the amount of the compound of Formula (I) actually administered will be determined by a physician, in light of the relevant circumstances of the patient, including the condition to be treated, the chosen route of administration, the actual compound administered and its relative activity, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like. [01631 For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. [0164] Tablets or pills may be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action, or to protect from the acid conditions of the stomach. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer that serves to resist disintegration in the stomach and 48 permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate. [0165] Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. Preferably the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions in preferably pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a face mask tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions may be administered, preferably orally or nasally, from devices that deliver the formulation in an appropriate manner. [0166] The following examples are included to demonstrate certain embodiments. It should be appreciated by those of skill in the art that the techniques disclosed in the examples which follow represent techniques discovered by the inventor to function well in the practice, and thus can be considered to constitute modes for its practice. However, those of skill in the art should, in light of the present disclosure, appreciate that many changes can be made in the specific embodiments which are disclosed and still obtain a like or. similar result without departing from the spirit and scope.

The dry-blended mixture is then granulated in the presence of an aqueous solution of a strong base which is sprayed into the blended powder. The granulate is dried, screened, mixed with optional lubricants (such as tale or magnesium stearate), and compressed into tablets. Certain aqueous solutions of strong bases are solutions of alkali metal hydroxides, such as sodium or potassium hydroxide, preferably sodium hydroxide, in water (optionally containing up to 25% of water-miscible solvents such as lower alcohols). [0215] The resulting tablets may be coated with an optional film-forming agent, for identification, taste-masking purposes and to improve ease of swallowing. The film forming agent will typically be present in an amount ranging from between 2% and 4% of the tablet weight. Suitable film-forming agents are well known to the art and include hydroxypropyl, methylcellulose, cationic methacrylate copolymers (dimethylaminoethyl methacrylate/ methyl-butyl methacrylate copolymers - Eudragit@ E - R6hm. Pharma) and the like. These film-forming agents may optionally contain colorants, plasticizers, and other supplemental ingredients. [0216] The compressed tablets preferably have a hardness sufficient to withstand 8 Kp compression. The tablet size will depend primarily upon the amount of compound in the tablet. The tablets will include from 300 to 1100 mg of compound free base. Preferably, the tablets will include amounts of compound free base ranging from about 10-200 mg, 100-300 mg, or 400-600 mg. [0217] In order to influence the dissolution rate, the time during which the compound containing powder is wet mixed is controlled. Preferably the total powder mix time, i.e., the time during which the powder is exposed to sodium hydroxide solution, will range from 1 to 10 minutes and preferably from 2 to 5 minutes. Following granulation, the particles are removed from the granulator and placed in a fluid bed dryer for drying at about 60'C. Example 17 [0218] ALDH2 Assays Standard ALDH2 reaction mixtures contained 150 uM formaldehyde, 2.5 mM NAD*, 10 mM MgCl2 and 10 nM recombinant human ALDH2 in 50 mM Hepes buffer, pH 7.4, 0.01%Tween 20 in a final volume of 50 ul using 384-well plates. After 60 min of pre incubation of compound with ALDH2 and formaldehyde, the reaction was started by adding 71 NAD+ and the reaction mixture was allowed to proceed for 90 minutes. Activity of the enzyme was determined by monitoring NADH formation using Perkin-Elmer Envision Reader with excitation and emission wavelengths set at 340 and 460 nm, respectively. MAO-A and MAO-B Assays MAO assays included luminogenic MAO substrate, reaction buffers, Luciferin Detection and the reconstitution buffer with esterase. Standard MAO reaction mixtures included microsome contained MAO-A (2 ug) or MAO-B (10 ug), 160uM substrate for MAO-A or l6uM substrate for MAO-B, MAO-A buffer (100 mM Hepes buffer, pH 7.5, 5% glycerol) or MAO B buffer (100 mM Hepes, pH 7.5, 5% glycerol, 10% dimethyl sulfoxide) in a final volume of 30 ul. After 20 minutes of pre-incubation of the enzyme with compounds, the reaction was initiated by adding enzyme substrate and the reaction was allowed to proceed for 60 minutes. Reconstituted Luciferin Detection Reagent (30 ul) was then added is added to simultaneously stop the MAO reaction and convert the methyl ester derivative to luciferin and produce light. The amount of light produced is directly proportional to the activity of MAO. The mixtures were further incubated for 20 minutes and activity of the enzyme was determined using Perkin-Elmer Envision Reader. Note: IC50 refers to the concentration of a compound that inhibits a reaction by 50%. In the case of competitive inhibition, IC50 = 2Ki when the substrate is present at the Km concentration, as per the relationship: Ki= IC50/[1 + (substrate concentration/Km)].

These rats consume significantly more alcohol than their respective control strains: the selectively-bred alcohol non-preferring (NP), the low alcohol-drinking (LAD) rat, and the Wistar rat. The FH and P rats are derived from the Wistar rat. Water and food (Agway Prolab Rat/Mouse/Hamster 3000 formula, Agway, Syracuse, USA) are provided ad lib. [0221] Establishment of Baseline: Following the standard method (Murphy et al., 1988; Rezvani and Grady, 1994; Rezvani et al., 1995), alcohol-preferring rats are given I day access to water in a Richter tube followed by 3 days of free access to a solution of 10% (v/v) ethanol given as the only source of fluid. Thereafter, the rats are given a choice between alcohol and water for the remainder of the study. All experiments involve 24 hour free access to food, water, and alcohol in a two-bottle choice paradigm. [02221 Experimental Protocol: After establishment of a stable baseline for alcohol and water intakes, animals are maintained on a continuous access to alcohol and water via a two bottle choice paradigm for about 2 months. Then, rats receive a single i.p. injection of the saline vehicle, or a test compound at 09:30 am. Alcohol and water intakes are measured at 6 and 24 hours after the injection. Food intake is measured 24 hours after the injection. [0223] Chronic Systemic Administration: A chronic experiment is conducted with adult male P rats. After establishment of stable baselines for alcohol and water intakes, and following a cross-over design, the test drug or vehicle is given i.p. once a day for 10 consecutive days. Alcohol and water intakes are measured at 6 and.24 hours after the treatment, whereas food intake is measured 24 hours after the treatment. Each rat receives both treatments, and a washout period of 3 days is imposed between treatments. [0224] Statistical Analysis: The results are expressed as means ± standard error of means (SEM). Alcohol intake (g/kg) is calculated by multiplying the volume of alcohol consumed by 10% and 0.7893 (ethanol density)/animal body weight in kg. Alcohol preference, expressed as a percentage, is calculated as follows: (volume of alcohol consumed in mL/total fluid intake in mL) x 100 (Rezvani et al., 1990; Rezvani and Grady, 1994). Statistical 74 differences between different groups are determined using analysis of variance followed by Newman-Keuls protected t-test. Rat alcohol self administration Alcohol-preferring (iP) male rats were trained to daily (Monday to Friday) self-administer alcohol (10% v/v) under operant conditions. A fixed-ratio of 3 (FR3), where rats had to press a lever 3 times to get one drop of alcohol during 20-min sessions was used (Cowen et al, 2005a; Cowen et al., 2005b; Lawrence et al., 2006). Availability of alcohol was conditioned by the presence of an olfactory cue (2 drops of vanilla essence, placed on the bedding of the operant chamber directly under the active lever), plus a 1-sec light stimulus when FR3 was obtained. For each session, total alcohol and water responses were recorded. Following acquisition of lever pressing behavior and stable alcohol self-administration, rats were administered oral vehicle or compound of Example 5 (5, 10 and 30 mg-eq/kg) 1 hr before each session in a counterbalanced order. Every rat received all drug doses and vehicle once per week in a randomly assigned order. Compound of Example 5 at 10 and 30 mg-eq/kg significantly decreased the number of lever presses for alcohol (Figure 1). Example 19 Reduction of Cocaine Dependency and Relapse [02251 Intravenous cocaine (0.35mg/kg/inj) is used in an operant self administration and reinstatement model in rats. In this model, rats addicted to cocaine repeatedly press a lever to obtain an intravenous dose (iv) of cocaine. When cocaine is removed, rats stop pressing the lever. However, rats resume lever pressing for cocaine (reinstatement) if subjected to a small intraperitoneal (ip) dose (10mg/kg) of cocaine that normally has no effect in naive animals. This is a valid animal model of relapse in cocaine addicted humans, and tests the ability of the compounds of Formula (I) to block cocaine craving and relapse. [0226] Male Sprague-Dawley rats with jugular vein catheterization are used. Rats are presented with a choice of two levers in the test/training chamber. Depression of the active lever results in delivery of a cocaine reinforcer, while depression of the inactive lever does not result in reinforcement. During the initial 15 hour fixed ratio (FR) 1 training session (FR1 stands for one lever press equals one reinforcement delivery), a food pellet is taped to the active lever to facilitate lever pressing, and each active lever press results in the delivery of a single 45 mg food pellet (Noyes, Lancaster, NH). The following day the reinforcer is switched to FR1 lever pressing for cocaine (0.35 mg/kg/inj, delivered in 0.27 sec). Cocaine 75 reinforcement is delivered on a modified FRI schedule such that each drug infusion is accompanied by illumination of a stimulus over the active lever and a 20 second timeout during which active lever presses are counted but do not result in reinforcer delivery. After 20 seconds the stimulus light is turned off and the first lever press again results in drug delivery. Depression of the inactive lever does not have any consequence. Daily training sessions for each group lasts 2 hours, or until a subject earns 200 drug infusions, whichever comes first. The subjects remain in drug self-administration training mode until acquisition criterion is met (average presses on the active lever varied by < 10% over 3 consecutive training days). This typically takes 10-14 days. Extinction and Reinstatement [0227] For extinction and reinstatement experiments, rats are required to display stable responding (variability not higher than 15% in 2 consecutive sessions) on the FRI schedule of reinforcement. After achieving these criteria, extinction procedures begin such that lever presses no longer result in delivery of the reinforcer. When average responding across three consecutive extinction sessions falls to 15% of responding during maintenance, subjects are tested for reinstatement. In cocaine-experienced animals, reinstatement is primed with a non contingent injection of cocaine (10 mg/kg ip) immediately before the reinstatement session. In order to increase statistical power and therefore decrease animal usage, a second extinction period is initiated 3-4 days after the first, which allows for additional within-subjects comparisons. Experiments use a between-session-training and testing method in which animals are trained to self administer drug. Their behavior is then extinguished and then reinstatement is primed on different days. Results: Effect of Compounds of Formula (I) on cocaine induced relapse [0228] Ip injections of the compounds of Formula (I) dose dependently block relapse for cocaine. Animals are trained to self administer cocaine (0.35 mg/kg/inj) until they reach stable responding. They are then trained in the same chambers but cocaine is no longer available. Once they drop their lever presses responding to a minimal level (extinction), they are then given a priming dose of cocaine (10 mg/kg) and consequently their responding lever presses significantly increase (relapse). Those same animals receiving effective compounds of Formula (I) prior to the priming injection of cocaine do not show an increase in their lever presses responding (did not relapse). 76 Rat Cocaine Cue Reinstatement Training of male Sprague Dawley (SD) rats had 3 separate stages. First, during self administration, animals were trained to lever press for cocaine with presentation of concomitant cues associated with drug delivery. Rats that reached criteria for addiction were included in the study. Afterward, during cue extinction, cocaine-cue dependent behavior was extinguished. Lastly, during cocaine cue reinstatement, the effect of compounds was tested on lever presses upon cue presentation (Fig. 2). Cocaine self administration Rats were trained to self administer i.v. cocaine (0.35 mg/kg/injection) daily (Monday to Friday) in standard operant chambers with retractable levers (Coulbourn Instruments, PA). During the daily 2 hr session, rats received a 0.05 ml infusion of 0.35 mg/kg cocaine every time the active lever was pressed. A cue light and tone turned on for 2 sec together with activation of a pump that delivered the cocaine solution. Rats were required to maintain an infusion rate of : 20+ per day for at least 10 days before being moved to extinction training. Rats that did not reach this criterion were excluded from the study. Cue extinction During extinction sessions lever presses no longer produced cocaine infusion and cue light/tone presentation was absent. Rats received a maximum of 15 extinction sessions. Rats were considered to have extinguished behavior when during 2 consecutive sessions they exhibited an average of < 15 active lever presses or 30% of the number of responses per session that occurred during the last 2 sessions of cocaine self-administration, whichever came first. Cocaine cue reinstatement On the next day after reaching extinction criteria, rats were treated orally with vehicle (Formulation 2B: 25% PEG400/5% Vit E TPGS/1% SLS/69% water with 0.5% Methocel) or drug (compound of Example 2 or compound of Example 5) before the cue reinstatement session. Cue reinstatement began with a tone and cue light. This 2 hr session was identical to the self-administration session (cue light and tone present upon active lever press) except that no cocaine was delivered. The number of active lever presses was compared to extinction 77 lever responding. This is considered a measure of reinstatement. The next day, rats were returned to extinction sessions for at least 2 or 3 more sessions. Rats then received a second and last reinstatement session with an opposite treatment to the one received on the first reinstatement session (vehicle or drug treatment). When rats pretreated with vehicle are presented with cues associated with cocaine availability, they significantly increase their number of lever presses. The light/tone presentation triggers this response and it is interpreted as a measure of reinstatement even though cocaine is not available. Compound of Example 2 significantly reduced cocaine cue-induced reinstatement in SD rats by 69%, 72% and 86% at 5, 10 and 30 mg/kg, respectively, when compared to vehicle (Figure 3). An ANOVA revealed a significant effect of treatment on number of lever presses. A significant effect of treatment was observed for all doses tested (p<0.001). Fisher post-hoc comparisons showed that rats treated with vehicle prior to cue reinstatement session had a significant increase in number of lever presses when compared with extinction session (p< 0.05). After treatment with compound of Example 2 (5, 10 or 30 mg/kg) prior to cue reinstatement session, rats significantly decreased lever presses responding compared with vehicle treatment (69% inhibition: p<0.05, 72% inhibition: p<0.05 and 86% inhibition: p<0.01, respectively). #p < 0.01 compared with extinction; * p<0.05,and ** p < 0.01 compared with vehicle. The prodrug compound of Example 5 was efficacious at 5, 10 and 30 mg-eq/kg in cocaine cue reinstatement with 59%, 55% and 50% inhibition, respectively (Figure 4). At the lowest dose tested, 2.5 mg-eq&g, the effect was not significantly different from vehicle. Compound of Example 5 reduced cocaine cue-induced reinstatement in SD rats. The number of lever presses was recorded during the 2 hr cue-induced reinstatement session. An ANOVA revealed a significant effect of treatment on number of lever presses. Rats that had extinguished lever press responding were treated with oral vehicle and compound of Example 5 (2.5, 5, 10 or 30 mg-eq/kg) 1 hr before the cue-induced reinstatement session. A significant effect of treatment was observed for 2.5, 5, 10 and 30 mg-eq/kg doses tested (2.5 mg/kg eq: F(2,28)= 9.39, p<0.01, n=15; 5 mg/kg eq: F(2,14)=l1,47, p<0.01, n =8; 10 mg/kg eq: F(2, 18)=13,901, p<0.001, n =10; 30 mg/kg eq: F(2, 22)=18.221, p<0.001, n =12). Fisher post hoc comparisons revealed that rats treated with vehicle prior to cue reinstatement session showed a significant increase in number of lever presses when compared with extinction 78 session (p< 0.01). After treatment with compound of Example 5 (5, 10 or 30 mg/kg) prior to cue reinstatement session, rats significantly decreased lever presses responding compared with vehicle treatment (59% inhibition: p<0.05, 55% inhibition: p<0.01 and 50% inhibition: p<0.01, respectively). Fisher post-hoc comparisons revealed that 2.5 mg/kg eq dose was not significantly different from vehicle (30% inhibition, p>0.05, N.S.). #p < 0.01 compared with extinction; * p<0.05 and ** p <0.01 compared with vehicle). Example 20 Reduction of Nicotine Dependency [0229] Biological Material: Wistar-derived male rats (250-300 g) are housed in groups of two and maintained in a temperature-controlled environment on a 12 hour:12 hour light cycle (0600h on-i 800h off), upon arrival in the laboratory. Animals are given free access to food and water during a one-week habituation period to the laboratory. Animals used in the research studies are handled, housed, and sacrificed in accord with the current NIH guidelines regarding the use and care of laboratory animals, and all applicable local, state, and federal regulations and guidelines. Animals are handled daily for several days to desensitize them to handling stress before experimental testing. Sample sizes (e.g., n=8) are sufficient to provide reliable estimates of drug effects. [0230] Drug Treatments: The Wistar-derived rats receive several doses of the compounds of Formula (I) administered intraperitonealy (i.p.), and a positive control compound, mecamylamine (1.5 mg/kg, subcutaneously (s.c.). The compounds are administered 30 minutes prior to SA sessions. The compounds of Formula (I) are administered at 2 mL/kg for the 7.5 mg/kg (3.75 mg/mL) and 10 mg/kg (5 mg/mL), doses, and at 3 mL/kg for the 15 mg/kg dose (5 mg/mL). The compound is dissolved in corn oil (VEH), and sonicated for at least 30-minutes, up to 2 hours prior to administration. Mecamylamine is dissolved in 0.09% isotonic saline and administered at a volume of 1 mL/kg. [0231] Apparatus: Food training and nicotine self-administration takes place in 8 standard Coulbourn operant chambers. Each chamber is housed in a sound-attenuated box. Operant chambers are equipped with two levers; mounted 2 cm above the floor, and a cue light mounted 2 cm above the right lever on the back wall of the chamber. For food training, a food hopper is located 2-cm to the left/right of either lever, in the middle of the back wall. 79 Intravenous infusions are delivered in a volume of 0.1 mL over a 1 second interval via an infusion pump (Razel, CT) housed outside of the sound attenuated chamber. [0232] Food Training: Lever pressing is established as demonstrated by the method of Hyytia et al., (1996). Initially, rats are restricted to 15 grams of food daily (approximately 85% of their free-feeding body weight). After the second day of food restriction, rats are trained to respond for food under a fixed-ratio 1 (FRI) schedule of reinforcement (1 food pellet for each lever press) with a 1 second time-out (TO-1s) after each reinforcement. Training sessions are given twice per day, and TO periods are gradually increased to 20 seconds. Once rats obtain a steady baseline responding at a FRi-TO20s schedule of reinforcement, they are returned to ad libitum food prior to preparation for intravenous jugular catheter implant surgery. [02331 Surgery: Rats are anesthetized with a ketamine/xylazine mixture and chronic silastic jugular catheters are inserted into the external jugular vein and passed subcutaneously to a polyethylene assembly mounted on the animal's back. The catheter assembly consists of a 13-cm length of silasitic tubing (inside diameter 0.31 mm; outside diameter 0.64 mm), attached to a guide cannula that is bent at a right angle. The cannula is embedded into a dental cement base and anchored with a 2 x 2 cm square of durable mesh. The catheter is passed subcutaneously from the rats back to the jugular vein where it is inserted and secured with a non-absorbable silk suture. Upon successful completion of surgery, rats are given 3-5 days to recover before self -administration sessions are started. During the recovery period, rats remain ad libitum food access, and have catheter lines flushed daily with 30 units/mL of heparinized saline containing 66 mg/mL of Timentin to prevent blood coagulation and infection in the catheters. [0234] Nicotine Self-Administration: Following successful recovery from catheter implant surgery, rats are again food deprived to 85% of their free-feeding body weight. Once self administration sessions begin, subjects are trained to IV self-administer nicotine in 1-hour baseline sessions, 5 days per week, under a FR1-TO-20 schedule of reinforcement until stable responding is achieved. Stable responding is defined as less than 20% variability across 3 consecutive sessions. After acquisition of stable responding for nicotine, various doses of the compounds of Formula (I) are tested using a within-subjects Latin square design. Rats are allowed to self -administer nicotine after treatment with each dose of the compounds of Formula (I) for 1 test session, and subsequently "rebaselined" for 1-3 days before the next dose probe during one test self-administrations sessions. Following the testing of the first 80 compound, rats receive the positive control compound, mecamylamine (1.5 mg/kg), administered according to a crossover design. [02351 During SA sessions, rats are flushed with saline before test session to ensure catheter patency, and again flushed after test sessions with 30 units/mL of heparinized saline containing 66 mg/mL of Timentin, to prevent blood coagulation and infection in the catheters. If catheter patency is in question, as demonstrated by an unexpected shift in response rates, or inability to draw blood from the catheter, -0.1 mL of a short-acting anesthetic (Brevital) is infused. Animals with patent catheters exhibit rapid loss of muscle tone within 3-seconds. Rats with catheters no longer patent according to the Brevital test are removed from the experiment. [02361 Data Analysis: Data is collected on-line from multiple operant chambers, and reported as mean cumulative number of bar presses for nicotine. The data is analyzed using the StatView statistical package on a PC-compatible computer. Results: The Effect of Compounds on Nicotine SelfAdministration: [02371 Increasing doses of the compounds of Formula (I) administered as described in the above protocol reduce the number of bar presses (plotted as the number of infusions) for nicotine administration. Rat nicotine self administration Acute treatment Male SD rats were trained to self administer i.v. nicotine (0.03 mg/kg/inj) daily (Monday to Friday) in standard operant chambers with retractable levers (MED Associates, Inc) as previously published (Levin et al., 2003; Levin et al., 2007). During the daily 45 min session, rats received 0.05 ml infusion of 0.03 mg/kg/infusion of nicotine every time the active lever was pressed. A cue light and tone turned on for 0.5 sec together with the activation of a pump that delivered the nicotine solution. Daily sessions were run for at least 10 days before the initiation of drug testing. Solutions of compounds of Example 2 and Example 5 were prepared fresh daily in Formulation 2B: 25% PEG400/5% Vit E TPGS/1% SLS/69% water with 0.5% Methocel) for oral dosing. Compound of Example 2 doses were administered in a counterbalanced design for testing 1 hr before each nicotine session. Every rat received all drug doses and vehicle in a randomly assigned order. The oral drug administrations were made twice per week. Compound of Example 2 at 10, 30 and 60 mg/kg significantly reduced 81 the number of nicotine infusions when compared to vehicle treatment (26%, 28% and 31% inhibition, respectively). Doses of 1 and 5 mg/kg were without effect (Figure 5). Compound of Example 5 was tested in a study using 4 independent groups. Each group received either oral vehicle or 1 of the 3 doses of compound of Example 5 (5, 10 or 30 mg-eq/kg). The 2 higher doses of compound of Example 5 (10 and 30 mg-eq/kg) significantly reduced the number of nicotine infusions when compared to vehicle treatment (51% and 68% inhibition, respectively). The 5 mg/kg dose was ineffective. Chronic treatment Upon completion of the acute compound of Example 5 treatment study, the same animals were used to test the effect of 7-day chronic oral administration of compound of Example 5 in the nicotine self administration model. Rats were treated orally with compound of Example 5 (5, 10 or 30 mg-eq/kg) or vehicle 1 hr before nicotine self administration session for 7 consecutive days. Compound of Example 5 at 10 and 30 mg-eq/kg significantly reduced the number of nicotine infusions when compared to vehicle treatment during the 7 days of chronic oral administration (48% and 62% inhibition, respectively). Similar to the acute treatment, the 5 mg eq/kg dose was ineffective (Figure 7). There was no development of tolerance to the therapeutic effect during the course of the study (data not shown). Animals in nicotine self administration studies had to reach pre defined criteria (e.g. rat strain, minimum number of nicotine infusions, consistent baseline nicotine self administration throughout the study, patent iv catheters, etc.) to be included in analysis.
