Description

TITLE
Substituted Cyclic Ureas and Derivatives Thereof Useful as Retroviral Protease Inhibitors FIELD OF THE INVENTION
This invention relates generally to substituted cyclic ureas and analogs thereof useful as retroviral protease inhibitors, pharmaceutical compositions comprising the same, and methods of using the same for treating viral infection.
BACKGROUND OF THE INVENTION
Current treatments for viral diseases usually involve administration of compounds that inhibit viral DNA synthesis. Current treatments for AIDS (Dagani, Chem. Eng. News, November 23, 1987 pp. 41-49) involve administration of compounds such as 2',3'-dideoxycytidine, trisodium phosphonoformate, ammonium 21-tungsto-9-antimoniate, 1-b-D-ribofuranoxyl-1,2,4-triazole-3-carboxamide, 3'-azido-3'-deoxythymidine
(AZT), and adriamycin that inhibit viral DNA synthesis; compounds such as AL-721 and polymannoacetate which may prevent HIV from penetrating the host cell; and
compounds which treat the opportunistic infections caused by the immunosupression resulting from HIV infection. None of the current AIDS treatments have proven to be totally effective in treating and/or reversing the disease. In addition, many of the compounds currently used to treat AIDS cause adverse side effects including low platelet count, renal toxicity, and bone marrow cytopenia.
Proteases are enzymes which cleave proteins at specific peptide bonds. Many biological functions are controlled or mediated by proteases and their
complementary protease inhibitors. The genomes of retroviruses encode a protease that is responsible for the proteolytic processing of one or more polyprotein precursors such as the pol and gag gene products. See Wellink, Arch . Virol . 98 1 (1988). Retroviral proteases most commonly process the gag precursor into the core proteins, and also process the pol precursor into reverse transcriptase and retroviral protease.
The correct processing of the precursor
polyproteins by the retroviral protease is necessary for the assembly of the infectious virions. It has been shown that in vi tro mutagenesis that produces protease- defective virus leads to the production of immature core forms which lack infectivity. See Crawford et al., J. Virol . 53 899 (1985); Katoh et al., Virology 145 280 (1985). Therefore, retroviral protease inhibition provides an attractive target for antiviral therapy. See Mitsuya, Nature 325 775 (1987).
The ability to inhibit a viral protease provides a method for blocking viral replication and therefore a treatment for viral diseases, such as AIDS, that may have fewer side effects, be more efficacious, and be less prone to drug resistance when compared to current treatments.
WO93/07128 discloses cyclic carbonyls as inhibitors of HIV protease and synthetic procedures for preparing HIV protease inhibitors.
WO92/21647 discloses cyclic carbonyls and sulfones as inhibitors of HIV protease.
Due to the pressing need for additional HIV related treatments, it is desirable to find new retroviral protease inhibitors. Thus, the present invention concerns novel substituted cyclic ureas and analogs thereof, which compounds are capable of inhibiting viral protease and which compounds are believed to serve as a means of combating viral diseases, such as AIDS. None of the above references teach or suggest the cyclic ureas of the present invention as inhibitors of HIV protease or for treatment of retroviral diseases, i.e., AIDS. The substituted cyclic ureas, and analogs thereof, provided by the present invention are
particularly useful as inhibitors of HIV protease and similar retroviral proteases. The compounds of the present invention are of low molecular weight and may, therefore, have good oral absorption properties in mammals. SUMMARY OF THE INVENTION
Accordingly, one object of the present invention is to provide novel retroviral protease inhibitors.
It is another object of the present invention is to provide a method for treating viral infections which comprises administering to a host in need of such treatment a therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form
thereof.
It is another object of the present invention to provide pharmaceutical compositions with retroviral protease inhibiting activity comprising a
pharmaceutically acceptable carrier and a
therapeutically effective amount of at least one of the compounds of the present invention or a pharmaceutically acceptable salt or prodrug form thereof.

SYNTHESIS
The compounds of the present invention can be prepared in a number of ways well known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or variations thereon as appreciated by those skilled in the art.
Preferred methods include but are not limited to those methods described below. Each of the references cited below are hereby incorporated herein by reference. All the temperatures are reported herein in degrees Celsius.
Compounds of the invention of the formula (Ia):
Figure imgf000081_0001
can be formed from diamines of formula ( III ) :
Figure imgf000081_0002
by cyclization with an appropriate cyclizing agent to give the corresponding cyclic urea, sulfinamide, sulfonamide, phosphoramide and cyanoguanidine compounds.
The diamines of formula (III) are either
commercially available or can be synthesized either (a) from the corresponding diols using one of several procedures that are known to one skilled in the art for converting alcohols to amines (see for example, Tet . Lett. 1991. 32, 999; Tetrahedron : . Asymmetry. 1991, 2, 981; Synthesis 1990, 1023); or (b) using the methods described below. As outlined in Scheme 1, diamines (III) can be synthesized from amino acid amides (IV) by alkylation with an organometallic reagent, for example, an orgaomagnesium halide, to yield an amino ketone which upon reduction using standard methods known in the art gives the amino alcohol (V) . The resulting alcohol can be converted to the desired diamine by displacement with azide ion and subsequent reduction using standard procedures well known to one skilled in the art of organic synthesis. Combined with the many procedures for making both natural and unnatural amino acids that are known to one skilled in the art, this route provides a wide variety of possible diamines. The diamines of formula (III) can be cyclized with suitable cyclizing reagents of formula J-(C=Z)-J', where J and J' are leaving groups, in a suitable solvent, optionally in the presence of a base, thereby to form a compound of formula (I) wherein T is R22NC(=Z)NR23. For compounds of formula (I) wherein T is
-N(R22)C(=O)N(R23)-, the suitable cyclizing reagent may be selected from, but is not limited to, phenyl
chloroformate, phenyl tetrazoylformate, urea, phosgene, triphosgene, oxalyl chloride, N,N'-disuccinimidyl carbonate, 1,1'-carbonyldiimidazole, trichloromethyl chloroformate, and 2(S),3-pyridinediyl thiocarbonate. A preferred cyclizing reagent, when T is -N(R22)C(=O)NR23-, is 1,1'-carbonyl diimidazole.
For compounds of formula (I) wherein T is
-N(R22)C(=S)N(R23)-, the suitable cyclizing reagent may be selected from, but is not limited to, 1,1'-thiocarbonyl diimidazole or carbon disulfide.
Preferably, the cyclizing reagent is 1,1'-thiocarbonyldiimidazole.
For compounds of formula (I) wherein T is
-N(R22)S(=O)2N(R23)-, the suitable cyclizing reagent may be selected from, but is not limited to, sulfamide.
For compounds where T is -N(R22)P(=0)(R24-)N(R25)-, the suitable aplying agent may be selected from, but is nottlimited to phenydichlorophosphate.
A base may optionally be included in the
above-described cyclizations in order to account for any acid-labile protecting groups that may be present. The base may be selected from organic bases which include, but are not limited to, pyridine, diisopropylethylamine, and triethylamine. The base may alternatively be selected from inorganic bases, such as, for example, sodium hydroxide.
Suitable solvents for the above cyclization include organic solvents or a biphasic suspension of water and an organic solvent. Suitable organic solvents include, but are not limited to, chloroform, methylene chloride, tetrachloroethane, butyl chloride, dichloroethane, tetrahydrofuran, N,N-dimethylformamide and toluene.
Preferred solvents are toluene or chloroform.
As used herein, the term "hydroxyl protecting group" means any group known in the art of organic synthesis for the protection of hydroxyl groups. Such protecting groups include those listed in Greene and Wuts, "Protective Groups in Organic Synthesis", John Wiley & Sons, New York (1991), the disclosure of which is hereby incorporated by reference. The hydroxyl protecting groups are base-stable and can include, but are not limited to acyl types, aromatic carbamate types and alkyl types. Exemplary are methyl, methoxymethyl, methylthiomethyl, benzyloxymethyl,
t-butoxymethyl, 2-methoxyethoxymethyl, 2,2,2-trichloroethoxymethyl, 2-(trimethylsilyl)ethoxymethyl, tetrahydropyranyl, tetrahydrofuranyl, t-butyl,
triphenylmethyl, trimethylsilyl, triethylsilyl,
t-butyldimethylsilyl, t-butyldiphenylsilyl, pivaloate or N-phenylcarbamate.
Another, preferred method to form compounds of formula (I), in cases wherein R22 and R23 are CH2R31, is to cyclize a compound of structure (III) where R22 and R23 are hydrogen, and to alkylate the resulting product at nitrogen using a base and an alkylating agent, optionally in the presence of a phase transfer catalyst, using methods well known in the art. The preferred base is sodium hydride, and the preferred alkylating agents are R22Y and R23Y, wherein Y is a halogen, triflate, or mesylate, preferably a bromide or iodide. The details of the above preferred alkylation conditions have been described in detailed in European patent application WO93/07128. Cleavage of protecting groups, if employed, yields structures of formula (I).
Figure imgf000084_0001
Alternately, diamines of formula III can be prepared from commercially-available 2,3-dibromosuccinic acid following the procedure described by Lavielle et al. (JACS 1978 100(5) 1558-1563). Displacement of bromine with an appropriate amine, such as, for example, benzylamine, gives the corresponding 2,3-bis(amino)succinic acid. Cyclization of the diamine with one of the cyclizing reagents described above gives a cyclic intermediate which is converted to a compound of formula I using procedures well known to one skilled in the art of organic synthesis. For example, as illustrations in Scheme 2, cyclization of diamine X with phosgene gives dicarboxyimidazolidinone XI. The carboxylic acid groups are then converted to N,O-dimethylhydroxyamides by treatment with 1,1- carbonyldiimidazole followed by N,O-dimethylhydroxylamine hydrochloride. Treatment of diamide XII with 2 equivalents of an organometallic reagent, for example, an organomagnesium halide, provides a diketone compound XIII. Further manipulation of the ketone functions using standard procedures for interconversion of functional groups gives additional compounds of formula I.
Figure imgf000086_0001
An alternate synthesis of diketone (XIII) is shown in Scheme 2a. Cyclization of dicyanoethylenediamine with phosgene followed by alkylation using conditions described above provides dinitrile XV. Reduction of the double bond and treatment with an appropriate
organometallic reagent, i.e., an organomagnesium halide or organocadmium compound, gives diketone XIII.
Figure imgf000087_0001
Alternately, the compounds of this invention may be synthesized by ring contraction of the corresponding 6- or 7-membered ring cyclic compounds XVIII and XIX. The 6- and 7-membered ring cyclic compounds are prepared according to the procedures described in European patent application WO9307128. As outlined in Scheme 3 the 6- and 7-membered compounds can be converted to the corresponding fluoro-substituted 5-membered ring cyclic compounds of formula I by treatment with DAST or under Mitsunobu type conditions to give the hydroxy, bromo unsubstituted compounds of formula I XXI, XXIII, and IX respectively.
Figure imgf000088_0001
Compounds of formula I wherein R1 and R2 combine to form a 6-membered saturated carbocyclic ring can be prepared by utilizing a Diels-Alder cyclization to prepare the 6-membered ring. Diels-Alder condensation of the appropriately substituted diene and dienophile as depicted in Scheme 4 would provide a 4,5-dicarbomethoxycyclohexene system, XXIV. Conversion of the double bond to the trans diol (reference or
reagents), hydrolysis of the diester and double Hofmann degradation would give the diamine XXV. Suitable protection of the diol, followed by cyclization and alkylation using procedures described above affords compounds of the invention of formula XXVI.
Figure imgf000089_0001
Stereochemical control can be achieved via
intramolecular cyclization as outlined in Scheme 4a. The synthesis of compound XVII is based on a procedure described by Ndibwami et al. ( Can . J. Chem. 1993, 71 , 695). The control of relative stereochemistry in the Diels-Alder cyclization can be achieved by judicious choice of cis/trans diene and trans dienophile.
Catalysis with chiral Lewis acids can be used to control the absolute stereochemistry, if desired.
Figure imgf000090_0001
Compounds of formula I wherein R1 and R2 combine to form a 5-membered saturated carbocyclic ring can be prepared from an appropriately substituted cyclopentene compound via the series of steps outlined in Scheme 5. Treatment of a suitably protected 4-hydroxycyclohexene with osmium tetroxide gives a cis-diol, XXXIV.
Oxidation of the diol to the diketone XXXV can be achieved by a number of methods known to one skilled in the art, for example, but not limited to, Swern
oxidation (Manacuso & Swern, Synthesis 1981, 165) or Tempo oxidation (Leanna et al., Tetrahedron Lett., 1992, 33, 5029). Conversion of the diketone to the bisoxime by treatment with hydroxylamine followed by alkylation with an apropriate organometallic reagent provides diamine XXVII. Cyclization to the cyclic urea or sulfonamide with CDI or sulfamide, respectively, followed by alkylation on nitrogen and deprotection of the diol provides XXXII.
Figure imgf000091_0001
Compounds of formula I, wherein R1 and R2 are combined to form a six-membered aromatic carbocycle or heterocycle, can be prepared by cyclization of 1,2-phenylene diamines or the corresponding 1,2-diaminoheterocycles using the cyclization methods described above. Illustrative syntheses are depicted in schemes 6 and 6a.
Figure imgf000092_0001
Compounds of formula I wherein T is
- (R22)NC(=O)N(R23)- and R1 and R2 are combined to form a 5-membered sulfur containing heterocycle can be
alkylation of biotin or derivatives thereof via the synthetic sequence depicted in Scheme 7. The resulting biotin derivative XLVII can be optionally oxidized to the corresponding sulfoxide XLVIII or sulfone XLIX using a variety of methods for oxidation of mercaptons well known in the art.
Figure imgf000093_0001
Reductive amination of diketone XIII will provide cyclic compounds of formula L. Alternately compounds wherein R1 and R2 are combined to form a 5-membered aromatic heterocycle can be prepared from diketone XIII by a modification of procedures described by R.
Ramasseul and A. Rassat (Bull. Soc. Chim. Fr., 1970, No. 12, pp. 4330-4341).
Figure imgf000093_0002
As illustrated in Scheme 9, treatment of diol XlVa with methanesulfonyl chloride provides a bismesylate which on treatment with sodium sulfide cyclizes to compound LII. Compounds of formula LII can be further converted to the corresponding sulfoxides, sulfones and sulfamoyl compounds using standard methodology to give additional examples of the present invention.

Protease: Inclusion bodies of E. coli harboring plasmid T1718R with a synthetic gene coding for a single-chain tethered dimer of HIV protease were prepared as described in Cheng et al. Proc. Natl . Acad. Sci . USA 1990, 87, 9660. Active protease was prepared as described therein by extraction with 67% acetic acid, dilution 33-fold with water, dialysis against water and then against a "refolding buffer" comprising 20 mM MES, 1 mM dithiothreitol and 10% glycerol, pH 5.5. Protease was stored as a stock preparation at 10 μM in refolding buffer.
Substrate: Peptide of the sequence aminobenzoyl-Ala-Thr-His-Gln-Val-Tyr-Phe(NO2)-Val-Arg-Lys-Ala
containing p-nitrophenylalanine (Phe(NO2)), was prepared by solid phase synthesis as previously described (Cheng et al. Proc . Natl . Acad. Sci . USA 1990, 87, 9660).
Stock solutions of 2 mM substrate were prepared in DMSO.
Inhibitory compounds were dissolved in sufficient DMSO to make 3 mM stock solutions. All further
dilutions were prepared in "assay buffer" comprising 1 M NaCl, 50 mM MES, pH 5.5, 1 mM EDTA, lmM DTT and 20% glycerol.
Reactions:
Enzyme reaction: To a 2 mL screw-cap centrifuge tube were added 50 uL protease (final concentration 0.25 nM) and 0.1 mL inhibitor compound (final concentration 0.1-12,500 nM). After 15 min preincubation at room temperature, the reaction was started by the addition of 0.05 mL substrate (final concentration 5 μM) .
Incubation was carried out at 30°C for 1 hr. The reaction was stopped by addition of 1 mL of 0.1 M ammonium hydroxide solution.
HPLC measurement of product formation: The product (aminobenzoyl-Ala-Thr-His-Gln-Val-Tyr) was separated from substrate on a Pharmacia MonoQ anion exchange column. The injection volume was 0.2 mL. The mobile phases comprised: solution A (20 mM tris HCl, pH 9.0, 0.02% sodium azide, 10% acetonitrile), and solution B (20 mM tris HCl, pH 9.0, 0.02% sodium azide, 0.5 M ammonium formate, 10% acetonitrile). The mobile phases were pumped at 1 mL/min, with a gradient from 0 to 30% B in 5 min, 100% B for 4 min to wash the column, and a re- equilibration wash with A for 4 min. The retention time of the product was 3.6 min. Detection with a Shimadzu model RF535 fluorescence monitor was at 330 nm
(excitation) and 430 nm (emission). The Ki was
calculated from the formula Ki = 1/(((Km+S-FA*S)/(FA*Km))-1) where I = inhibitor concentration, S = substrate concentration, FA = fractional activity = cm peak height with inhibitor/cm peak height without inhibitor and Km = Michaelis constant = 20 μM.
HIV RNA Assay
DNA Plasmids and in vi tro RNA transcripts;
Plasmid pDAB 72 containing both gag and pol sequences of BH10 (bp 113-1816) cloned into PTZ 19R was prepared according to Erickson-Viitanen et al. AIDS Research and Human Retroviruses 1989, 5, 577. The plasmid was linearized with Bam HI prior to the
generation of in vi tro RNA transcripts using the
Riboprobe Gemini system II kit (Promega) with T7 RNA polymerase. Synthesized RNA was purified by treatment with RNase free DNAse (Promega), phenol-chloroform extraction, and ethanol precipitation. RNA transcripts were dissolved in water, and stored at -70°C. The concentration of RNA was determined from the A260.
Probes:
Biotinylated capture probes were purified by HPLC after synthesis on an Applied Biosystems (Foster City, CA) DNA synthesizer by addition of biotin to the 5' terminal end of the oligonucleotide, using the biotin-phosphoramidite reagent of Cocuzza, Tet . Lett . 1989, 30, 6287. The gag biotinylated capture probe (5-biotin-CTAGCTCCCTGCTTGCCCATACTA 3') was complementary to nucleotides 889-912 of HXB2 and the pol biotinylated capture probe (5'-biotin -CCCTATCATTTTTGGTTTCCAT 3' ) was complementary to nucleotides 2374-2395 of HXB2.
Alkaline phosphatase conjugated oligonucleotides used as reporter probes were prepared by Syngene (San Diego, CA.). The pol reporter probe (5'
CTGTCTTACTTTGATAAAACCTC 3') was complementary to nucleotides 2403-2425 of HXB2. The gag reporter probe (5' CCCAGTATTTGTCTACAGCCTTCT 3') was complementary to nucleotides 950-973 of HXB2. All nucleotide positions are those of the GenBank Genetic Sequence Data Bank as accessed through the Genetics Computer Group Sequence Analysis Software Package (Devereau Nucleic Acids
Research 1984, 12, 387). The reporter probes were prepared as 0.5 μM stocks in 2 × SSC (0.3 M NaCl, 0.03 M sodium citrate), 0.05 M Tris pH 8.8, 1 mg/mL BSA. The biotinylated capture probes were prepared as 100 μM stocks in water. Streptavidin coated plates:
Nunc-immunomodule microtiter plate strips were coated by addition of 200 μL of streptavidin (30 μg/mL, Scripps, La Jolla, CA) in freshly prepared 10 mM sodium carbonate (pH 9.6). Plates were incubated overnight at 4°C. Streptavidin solution was aspirated from the wells and a blocking buffer composed of phosphate buffered saline (PBS), 20 mg/mL bovine serum albumin
(crystalline, nuclease and protease free, Calbiochem) and 100 mg/mL lactose (Sigma) was added to the plates for 3 hrs at room temperature. Blocking buffer was removed from the wells, which were allowed to dry overnight at room temperature and subsequently stored at 4°C in zip lock bags with desiccant. For the majority of the compound evaluation experiments, streptavidin coated plates were obtained from Du Pont Biotechnology Systems (Boston, MA).
Cells and virus stocks;
MT-2, CEM, and H9 cells were maintained in RPMI 1640 supplemented with 5% fetal calf serum (FCS), 2 mM L-glutamine and 50 μg/mL gentamycin, all from Gibco. Laboratory strains of HIV-1 (RF, MN and IIIB) were propagated in H9 cells in the same medium. Virus stocks were prepared approximately 1 month after acute
infection of H9 cells by clarification of the tissue culture medium and storage of aliquots at -70°C. Infectious titers of HIV-1(RF) stocks were 1-3 × 107 PFU (plaque forming units)/mL as measured by plaque assay on MT-2 cells (see below). Each aliquot of virus stock used for infection was thawed only once. In some cases, infected H9 cells were shifted to Dulbecco's modified Eagle's medium 3-10 days before collection of virus in order to generate virus stocks in medium with low biotin content. Clinical isolates of HIV that had been passaged once in MT-2 cells were used to infect fresh MT-2 cells in RPMI medium. Three days after infection, cells were pelleted, resuspended and culture continued in Dulbecco's modified Eagle's medium as above. Virus stocks of clinical isolates were prepared 10-15 days after infection when cytopathic effects were apparent in the culture.
For evaluation of antiviral efficacy, cells to be infected were subcultured one day prior to infection. On the day of infection, cells were resuspended at 5 x 105 cells/mL in RPMI 1640, 5% FCS for bulk infections or at 2 × 106/mL in either Dulbecco's modified Eagles medium, or RPMI 1640 medium minus biotin (Gibco, custom formulation) with 5% FCS for infection in microtiter plates. Virus was added and culture continued for 3 days at 37°C. In some experiments, virus was removed after an initial adsorption period.
Preparation of HIV-1 infected cell lysates:
HIV-1 infected cells were pelleted by
centrifugation. After removal of the supernatant the cells were resuspended at a concentration of 1 × 107 cells/mL in 5 M guanidinium isothiocyanate solution (GED: 5 M guanidinium isothiocyanate (Sigma), 0.1 M EDTA, 10% dextran sulfate). Alternately, cells grown in biotin free tissue culture medium were mixed with 5 M GED to a final concentration of 3 M guanidinium
isothiocyanate, 0.06 M EDTA and 6% dextran sulfate. HIV RNA assay:
Cell lysates or purified RNA in 3 M or 5 M GED were mixed with 5 M GED and capture probe to a final
guanidinium isothiocyanate concentration of 3 M and a final biotin oligonucleotide concentration of 30 nM. Hybridization was carried out in sealed microfuge tubes or in sealed U bottom 96 well tissue culture plates (Nunc or Costar) for 16-20 hours at 37°C. RNA
hybridization reactions were diluted three-fold with deionized water to a final guanidinium isothiocyanate concentration of 1 M and aliquots (150 μL) were
transferred to streptavidin coated microtiter plates wells. Binding of capture probe and capture probe-RNA hybrid to the immobilized streptavidin was allowed to proceed for 2 hours at room temperature, after which the plates were washed 6 times with DuPont ELISA plate wash buffer (phosphate buffered saline(PBS), 0.05% Tween 20.) A second hybridization of reporter probe to the
immobilized complex of capture probe and hybridized target RNA was carried out in the washed streptavidin coated well by addition of 120 μl of a hybridization cocktail containing 4 X SSC, 0.66% Triton X 100, 6.66% deionized formamide, 1 mg/mL BSA and 5 nM reporter probe. After hybridization for one hour at 37 C, the plate was again washed 6 times. Immobilized alkaline phosphatase activity was detected by addition of 100 μL of 0.2 mM 4-methylumbelliferyl phosphate (MUBP, JBL Scientific) in buffer δ (2.5 M diethanolamine pH 8.9 (JBL Scientific), 10 mM MgCl2, 5 mM zinc acetate dihydrate and 5 mM N-hydroxyethyl-ethylene-diamine-triacetic acid). The plates were incubated at 37°C. Fluorescence at 450 nM was measured using a microplate fluorometer (Dynateck) exciting at 365 nM. Microplate based compound evaluation in HIV-1 infected MT-2 cells:
Compounds to be evaluated were dissolved in DMSO and diluted in culture medium to twice the highest concentration to be tested and a maximum DMSO
concentration of 2%. Further three-fold serial
dilutions of the compound in culture medium were
performed directly in U bottom microtiter plates (Nunc) . After compound dilution, MT-2 cells (50 μL) were added to a final concentration of 5 × 105 per mL (1 × 105 per well). Cells were incubated with compounds for 30 minutes at 37°C in a CO2 incubator. For evaluation of antiviral potency, an appropriate dilution of HIV-1 (RF) virus stock (50 μL) was added to culture wells
containing cells and dilutions of the test compounds. The final volume in each well was 200 μL. Eight wells per plate were left uninfected with 50 μL of medium added in place of virus, while eight wells were infected in the absence of any antiviral compound. For
evaluation of compound toxicity, parallel plates were cultured without virus infection.
After 3 days of culture at 37°C in a humidified chamber inside a CO2 incubator, all but 25 μL of
medium/well was removed from the HIV infected plates. Thirty seven μL of 5 M GED containing biotinylated capture probe was added to the settled cells and remaining medium in each well to a final concentration of 3 M GED and 30 nM capture probe. Hybridization of the capture probe to HIV RNA in the cell lysate was carried out in the same microplate well used for virus culture by sealing the plate with a plate sealer
(Costar), and incubating for 16-20 hrs in a 37°C incubator. Distilled water was then added to each well to dilute the hybridization reaction three-fold and 150 μL of this diluted mixture was transferred to a
streptavidin coated microtiter plate. HIV RNA was quantitated as described above. A standard curve, prepared by adding known amounts of pDAB 72 in vitro RNA transcript to wells containing lysed uninfected cells, was run on each microtiter plate in order to determine the amount of viral RNA made during the infection.
In order to standardize the virus inoculum used in the evaluation of compounds for antiviral activity, dilutions of virus were selected which resulted in an IC90 value (concentration of compound required to reduce the HIV RNA level by 90%) for dideoxycytidine (ddC) of 0.2 μg/mL. IC90 values of other antiviral compounds, both more and less potent than ddC, were reproducible using several stocks of HIV-1 (RF) when this procedure was followed. This concentration of virus corresponded to ~3 × 105 PFU (measured by plaque assay on MT-2 cells) per assay well and typically produced approximately 75% of the maximum viral RNA level achievable at any virus inoculum. For the HIV RNA assay, IC90 values were determined from the percent reduction of net signal (signal from infected cell samples minus signal from uninfected cell samples) in the RNA assay relative to the net signal from infected, untreated cells on the same culture plate (average of eight wells). Valid performance of individual infection and RNA assay tests was judged according to three criteria. It was required that the virus infection should result in an RNA assay signal equal to or greater than the signal generated from 2 ng of pDAB 72 in vi tro RNA transcript. The IC90 for ddC, determined in each assay run, should be between 0.1 and 0.3 μg/mL. Finally, the plateau level of viral RNA produced by an effective protease inhibitor should be less than 10% of the level achieved in an uninhibited infection.
For antiviral potency tests, all manipulations in microtiter plates, following the initial addition of 2X concentrated compound solution to a single row of wells, were performed using a Perkin Elmer/Cetus ProPette.

Dosage and Formulation
The antiviral compounds of this invention can be administered as treatment for viral infections by any means that produces contact of the active agent with the agent's site of action, i.e., the viral protease, in the body of a mammal. They can be administered by any conventional means available for use in conjunction with pharmaceuticals, either as individual therapeutic agents or in a combination of therapeutic agents. They can be administered alone, but preferably are administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard
pharmaceutical practice.
The dosage administered will, of course, vary depending upon known factors, such as the
pharmacodynamic characteristics of the particular agent and its mode and route of administration; the age, health and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent
treatment; the frequency of treatment; and the effect desired. A daily dosage of active ingredient can be expected to be about 0.001 to about 1000 milligrams per kilogram of body weight, with the preferred dose being about 0.1 to about 30 mg/kg. Dosage forms of compositions suitable for
administration contain from about 1 mg to about 100 mg of active ingredient per unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.5-95% by weight based on the total weight of the composition. The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets and powders, or in liquid dosage forms, such as elixirs, syrups and suspensions. It can also be administered parenterally, in sterile liquid dosage forms.
Gelatin capsules contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours.
Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective
disintegration in the gastrointestinal tract. Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.
In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions.
Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents.
Also used are citric acid and its salts, and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben and chlorobutanol. Suitable
pharmaceutical carriers are described in Remington ' s Pharmaceutical Sciences, supra , a standard reference text in this field.
Useful pharmaceutical dosage-forms for
administration of the compounds of this invention can be illustrated as follows: Capsules
A large number of unit capsules are prepared by filling standard two-piece hard gelatin capsules each with 100 mg of powdered active ingredient, 150 mg of lactose, 50 mg of cellulose, and 6 mg magnesium stearic.
Soft Gelatin Capsules
A mixture of active ingredient in a digestible oil such as soybean oil, cottonseed oil or olive oil is prepared and injected by means of a positive
displacement pump into gelatin to form soft gelatin capsules containing 100 mg of the active ingredient. The capsules are washed and dried.
Tablets
A large number of tablets were prepared by
conventional procedures so that the dosage unit was 100 mg of active ingredient, 0.2 mg of colloidal silicon dioxide, 5 milligrams of magnesium stearate, 275 mg of microcrystalline cellulose, 11 mg of starch and 98.8 mg of lactose. Appropriate coatings may be applied to increase palatability or delay absorption.
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise that as specifically described herein.
