Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Application Number: Lodged: Invention Title: Use of lipoxin compounds for inhibiting of TNF-(alfa) initiated neutrophil response The following statement is a full description of this invention, including the best method of performing it known to us: 0 USE OF LIPOXIN COMPOUNDS FOR INHIBITING OF TNF-(ALFA) INITIATED NEUTROPHIL RESPONSE 9 BACKGROUND OF THE INVENTION O Lipid and protein mediators of inflammation such as cytokines and chemokines C N have a profound impact on the formation and actions of each other (Serhan,.C.N., HaeggstrOm, and C.C. Leslie. 1996. Lipid mediator networks in cell signaling: update and 0 impact of cytokines. FASEB J. 10:1147-1158). In particular, the cytokines TNFa and IL- O0 S1P1 play major roles in inflammation, septic shock and tissue injury. PMN perform a range of well-appreciated specialized functions, including chemotaxis, generation of reactive Soxygen species and biosynthesis of potent lipid mediators (Weiss, S.J. 1989. Tissue destruction by neutrophils. N. Engl. J Med. 320:365-376). In this regard, TNFa stimulates PMN to transcribe and release cytokines such as IL- P, enhances leukotriene biosynthesis, and up-regulates adhesion molecules (Marucha, R.A. Zeff, and D.L.

Kreutzer. 1991. Cytokine-induced IL-11 gene expression in the human polymorphonuclear leukocyte: transcriptional and post-transcriptional regulation by tumor necrosis factor and IL-1. J Immunol. 147:2603-2608). Since PMN represent approximately 70% of the peripheral blood leukocytes and are in many instances the initial cell type recruited to interstitial sites, they are now considered a significant source of"proinflammatory" cytokines including TNFa and IL-11. These as well as other PMN-derived cytokines and chemokines can, in turn, affect the course of inflammatory and immune responses (Lloyd, and J.J. Oppenheim. 1992. Poly's lament: the neglected role of the polymorphonuclear neutrophil in the afferent limb of the immune response. Immunology Today 13:169-172). In certain clinical settings, including respiratory distress syndrome, myocardial reperfusion injury, gout and rheumatoid arthritis, PMN contribute to ongoing damage of host tissues (Weiss, S.J. 1989. Tissue destruction by neutrophils. N. Engl. J. Med. 320:365-376; Hachicha, P.H. Naccache, and S.R. McColl. 1995. Inflammatory microcrystals differentially regulate the secretion of macrophage inflammatory protein-1 and interleukin-8 by human neutrophils: A possible mechanism of neutrophil recruitment to sites of inflammation in synovitis. J Exp. Med. 182:2019-2025; Hansen, P.R. 1995. Role of neutrophils in myocardial ischemia and reperfusion. Circulation 91:1872-1885). Thus, it is of interest to understand the complex relationships between lipid mediators and TNFa-evoked PMN responses in order to gain insight for new approaches in controlling these events.

The impact of lipoxin A 4

(LXA

4 and aspirin-triggered-lipoxins (ATL) was investigated in tumor necrosis factor (TNFa)-initiated neutrophil (PMN) responses in vitro and in vivo using metabolically stable LX analogs. At concentrations as low as 1-10 nM, the LXA, and ATL analogs each inhibited TNFa-stimulated superoxide anion generation and IL-lp release by human PMN. These LXA 4 -ATL actions were time- and concentration-dependent and proved selective for TNFa, since these responses were not r altered with either GM-CSF or zymosan-stimulated cells. TNFa-induced IL-1 gene O expression was also regulated by both anti-LXA 4 -receptor antibodies and LXA.-ATL analogs. In murine air pouches, 15 R/S-methyl-LXA 4 dramatically inhibited TNFa- N stimulated leukocyte trafficking, as well as the appearance of both macrophage inflammatory peptide-2 and IL-1P, while concomitantly stimulating IL-4 in pouch 00 exudates. Together, these results indicate that both LXA 4 and ATL regulate TNFa directed neutrophil actions in vitro and in vivo and stimulate IL-4 in exudates, which plays a pivotal role in immune responses.

The contribution of leukotriene (LT')B 4 in inflammation is well established in view of its potent ability to attract PMN. Another series of bioactive lipid mediators termed lipoxins (LX) and aspirin-triggered lipoxins (ATL) each, within the nanomolar range, inhibits fMLP and LTB 4 stimulated PMN adhesion and transmigration and hence are proposed counter-regulatory signals operative in the resolution of inflammatory sites (Serhan, J.Z. Haeggstr6m, and C.C. Leslie. 1996. Lipid mediator networks in cell signaling: update and impact of cytokines. FASEB J. 10:1147-1158; Takano, S. Fiore, J.F. Maddox, H.R. Brady, N.A. Petasis, and C.N.

In human tissues, three main o pathways are known for LX generation. An intraluminal source of LX is exemplified by N PMN-platelet interactions that utilize sequential transcellular biosynthetic routes with the PMN 5-lipoxygenase (LO) product LTA 4 and platelet 12-LO. The mucosal and/or S interstitial source of these eicosanoids involves cell-cell interactions with leukocyte 00 and 15-LO present in, for example, eosinophils, gastrointestinal or tracheal epithelium that is controlled by IL-4 and IL-13 (reviewed in (Serhan, J.Z. Haeggstram, and C.C. Leslie. 1996. Lipid mediator networks in cell signaling: update and impact of cytokines. FASEB J. 10:1147-1158)). The third and most recently elucidated also represents a novel mechanism of action for aspirin that triggers the endogenous biosynthesis of 15 R epimers of native LX, termed aspirin-triggered lipoxins (ATL), generated via transcellular biosynthesis (ClAria, and C.N. Serhan. 1995. Aspirin triggers previously undescribed bioactive eicosanoids by human endothelial cellleukocyte interactions. Proc. Nail. Acad. Sci. USA 92:9475-9479).

LX are generated during cell-cell interactions via transcellular biosynthesis, and are produced in vivo during angioplasty and in immune complex glomerulonephritis (Serhan, J.Z. Haeggstr6m, and C.C. Leslie. 1996. Lipid mediator networks in cell signaling: update and impact of cytokines. FASEB J. 10:1147-1158; Papayianni,

4 is also present in nasal lavage fluids of aspirin-sensitive asthmatics and is generated by leukocytes from patients with asthma and rheumatoid arthritis (Chavis, I. Vachier, P. Chanez, J. Bousquet, and P.

To advance the understanding of LX and ATL roles in vivo, metabolically 0 stable LX analogs were designed that resist rapid inactivation and mimic the in vitro I actions of naturally occurring LX and ATL (Serhan, J.F.

OH

00 In a preferred embodiment, the pharmaceutical carrier is not a ketone, acetone.

O

In one embodiment, the antiinflammatories of the invention can be incorporated into a shampoo or a body cleansing product, a soap, for cleansing of the scalp and/or body. The use of these compounds in a shampoo or soap product can be used to treat psoriasis, seborrheic dermatitis, pustular dermatosis and dandruff. Thus the compounds are useful for modulating TNF aPMN or cytokine inflammation associated with such conditions.

A "lipoxin analog" shall mean a compound which has an "active region" that functions like the active region of a "natural lipoxin", but which has a "metabolic transformation region" that differs from natural lipoxin. Lipoxin analogs include compounds which are structurally similar to a natural lipoxin, compounds which share the same receptor recognition site, compounds which share the same or similar lipoxin metabolic transformation region as lipoxin, and compounds which are art-recognized as being analogs of lipoxin. Lipoxin analogs include lipoxin analog metabolites. The compounds disclosed herein may contain one or more centers of asymmetry. Where asymmetric carbon atoms are present, more than one stereoisomer is possible, and all possible isomeric forms are intended to be included within the structural representations shown. Optically active and isomers may be resolved using conventional techniques known to the ordinarily skilled artisan. The present invention is intended to include the possible diastereiomers as well as the racemic and optically resolved isomers.

-23- SThe terms "corresponding lipoxin" and "natural lipoxin" refer to a naturallyoccurring lipoxin or lipoxin metabolite. Where an analog has activity for a lipoxin- O specific receptor, the corresponding or natural lipoxin is the normal ligand for that CI receptor. For example, where an analog is a LXA 4 specific receptor on differentiated cells, the corresponding lipoxin is LXA 4 Where an analog has activity as an in antagonist to another compound (such as a leukotriene), which is antagonized by a 00 naturally-occurring lipoxin, that natural lipoxin is the corresponding lipoxin.

C-I "Active region" shall mean the region of a natural lipoxin or lipoxin analog, which is associated with in vivo cellular interactions. The active region may bind the

O

"recognition site" of a cellular lipoxin receptor or a macromolecule or complex of macromolecules, including an enzyme and its cofactor. Preferred lipoxin A 4 analogs have an active region comprising C 5 of natural lipoxin A 4 Preferred lipoxin B 4 analogs have an active region comprising C5-C14 of natural lipoxin B4.

The term "recognition site" or receptor is art-recognized and is intended to refer generally to a functional macromolecule or complex of macromolecules with which certain groups of cellular messengers, such as hormones, leukotrienes, and lipoxins, must first interact before the biochemical and physiological responses to those messengers are initiated. As used in this application, a receptor may be isolated, on an intact or permeabilized cell, or in tissue, including an organ. A receptor may be from or in a living subject, or it may be cloned. A receptor may normally exist or it may be induced by a.disease state, by an injury, or by artificial means. A compound of this invention may bind reversibly, irreversibly, competitively, noncompetitively, or uncompetitively with respect to the natural substrate of a recognition site.

The term "metabolic transformation region" is intended to refer generally to that portion of a lipoxin, a lipoxin metabolite, or lipoxin analog including a lipoxin analog metabolite, upon which an enzyme or an enzyme and its cofactor attempts to perform one or more metabolic transformations which that enzyme or enzyme and cofactor normally transform on lipoxins. The metabolic transformation region may or may not be susceptible to the transformation. A nonlimiting example of a metabolic transformation region of a lipoxin is a portion of LXA 4 that includes the C-13,14 double bond or the C-15 hydroxyl group, or both.

-24- O The term "detectable label molecule" is meant to include fluorescent, phosphorescent, and radiolabeled molecules used to trace, track, or identify the o compound or receptor recognition site to which the detectable label molecule is bound.

CI The label molecule may be detected by any of the several methods known in the art.

The term "labeled lipoxin analog" is further understood to encompass icompounds which are labeled with radioactive isotopes, such as but not limited to o0 tritium 3 deuterium carbon 4 or otherwise labeled fluorescently).

i The compounds of this invention may be labeled or derivatized, for example, for kinetic binding experiments, for further elucidating metabolic pathways and enzymatic Omechanisms, or for characterization by methods known in the art of analytical chemistry.

The term "inhibits metabolism" means the blocking or reduction of activity of an enzyme which metabolizes a native lipoxin. The blockage or reduction may occur by covalent bonding, by irreversible binding, by reversible binding which has a practical effect of irreversible binding, or by any other means which prevents the enzyme from operating in its usual manner on another lipoxin analog, including a lipoxin analog metabolite, a lipoxin, or a lipoxin metabolite.

The term "resists metabolism" is meant to include failing to undergo one or more of the metabolic degradative transformations by at least one of the enzymes which metabolize lipoxins. Two nonlimiting examples of LXA, analog that resists metabolism are 1) a structure which can not be oxidized to the 15-oxo form, and 2) a structure which may be oxidized to the 15-oxo form, but is not susceptible to enzymatic reduction to the 13,14-dihydro form.

The term "more slowly undergoes metabolism" means having slower reaction kinetics, or requiring more time for the completion of the series of metabolic transformations by one or more of the enzymes which metabolize lipoxin. A nonlimiting example of a LXA, analog which more slowly undergoes metabolism is a structure which has a higher transition state energy for C-15 dehydrogenation than does

LXA

4 because the analog is sterically hindered at the C-16.

The term "tissue" is intended to include intact cells, blood, blood preparations such as plasma and serum, bones, joints, muscles, smooth muscles, and organs.

The term "halogen" is meant to include fluorine, chlorine, bromine and iodine, c or fluoro, chloro, bromo, and iodo. In certain aspects, the compounds of the invention O do not include halogenated compounds, fluorinated compounds.

The formulations may conveniently be presented in unit dosage form and to may be prepared by any methods well known in the art of pharmacy. The amount of 0 active ingredient which can be combined with a carrier material to produce a single N dosage form will generally be that amount of the compound which produces a therapeutic effect. Generally, out of one hundred per cent, this amount will range from about 1 per cent to about ninety-nine percent of active ingredient, preferably from about 5 per cent to about 70 per cent, most preferably from about 10 per cent to about 30 per cent.

Methods of preparing these formulations or compositions include the step of bringing into association a compound of the present invention with the carrier and, optionally, one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association a compound of the present invention with liquid carriers, or finely divided solid carriers, or both, and then, if necessary, shaping the product.

Formulations of the invention suitable for oral administration may be in the form of capsules, cachets, pills, tablets, lozenges (using a flavored basis, usually sucrose and acacia or tragacanth), powders, granules, or as a solution or a suspension in an aqueous or non-aqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, or as an elixir or syrup, or as pastilles (using an inert base, such as gelatin and glycerin, or sucrose and acacia) and/or as mouth washes and the like, each containing a predetermined amount of a compound of the present invention as an active ingredient.

O

C, compound of this invention, excipients, such as animal and vegetable fats, oils, waxes, S paraffins, starch, tragacanth, cellulose derivatives, polyethylefie glycols; silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof.

OO Powders and sprays can contain, in addition to a compound of this invention, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays can additionally contain O customary propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.

Transdermal patches have the added advantage of providing controlled delivery of a compound of the present invention to the body. Such dosage forms can be made by dissolving or dispersing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate of such flux can be controlled by either providing a rate controlling membrane or dispersing the active compound in a polymer matrix or gel.

Ophthalmic formulations, eye ointments, powders, solutions and the like, are also contemplated as being within the scope of this invention.

Pharmaceutical compositions of this invention suitable for parenteral administration comprise one or more compounds of the invention in combination with one or more pharmaceutically acceptable sterile isotonic aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions just prior to use, which may contain antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents.

Examples of suitable aqueous and nonaqueous carriers which may be employed in the pharmaceutical compositions of the invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils, such as olive oil, and injectable organic esters, such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials, O such as lecithin, by the maintenance of the required particle size in the case of N dispersions, and by the use of surfactants.

O These compositions may also contain adjuvants such as preservatives, wetting

O

C agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also oo be desirable to include isotonic agents, such as sugars, sodium chloride, and the like into the compositions. In addition, prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption such as 0 aluminum monostearate and gelatin.

In some cases, in order to prolong the effect of a drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material having poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form.

Alternatively, delayed absorption of a parenterally-administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.

Injectable depot forms are made by forming microencapsule matrices of the subject compounds in biodegradable polymers such as polylactide-polyglycolide.

Depending on the ratio of drug to polymer, and the natureof the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissue.

The preparations of the present invention may be given orally, parenterally, topically, or rectally. They are of course given by forms suitable for each administration route. For example, they are administered in tablets or capsule form, by injection, inhalation, eye lotion, ointment, suppository, etc. administration by injection, infusion or inhalation; topical by lotion or ointment; and rectal by suppositories. Intravenous injection administration is preferred.

The phrases "parenteral administration" and "administered parenterally" as used herein means modes of administration other than enteral and topical administration, -32usually by injection, and includes, without limitation, intravenous, intramuscular, 1 intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, O intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal and intrastemal injection and infusion.

C N The phrases "systemic administration," "administered systematically," "peripheral administration" and "administered peripherally" as used herein mean the administration I of a compound, drug or other material other than directly into the central nervous system, such that it enters the patient's system and, thus, is subject to metabolism and other like processes, for example, subcutaneous administration.

SThese compounds may be administered to humans and other animals for therapy by any suitable route of administration, including orally, nasally, as by, for example, a spray, rectally, intravaginally, parenterally, intracisternally and topically, as by powders, ointments or drops, including buccally and sublingually.

Regardless of the route of administration selected, the compounds of the present invention, which may be used in a suitable hydrated form, and/or the pharmaceutical compositions of the present invention, are formulated into pharmaceutically acceptable dosage forms by conventional methods known to those of ordinary skill in the art.

Actual dosage levels of the active ingredients in the pharmaceutical compositions of this invention may be varied so as to obtain an amount of the active ingredient which is effective to achieve the desired therapeutic response for a particular patient, composition, and mode of administration, without being toxic to the patient.

The selected dosage level will depend upon a variety of factors including the activity of the particular compound of the present invention employed, or the ester, salt or amide thereof, the route of administration, the time of administration, the rate of excretion of the particular compound being employed, the duration of the treatment, other drugs, compounds and/or materials used in combination with the particular compound employed, the age, sex, weight, condition, general health and prior medical history of the patient being treated, and like factors well known in the medical arts.

A physician or veterinarian having ordinary skill in the art can readily determine and prescribe the effective amount of the pharmaceutical composition required. For example, the physician or veterinarian could start doses of the compounds of the invention employed in the pharmaceutical composition at levels lower than that required in order to achieve the desired therapeutic effect and gradually increase the dosage until the desired effect is achieved.

In general, a suitable daily dose of a compound of the invention will be that O amount of the compound which is the lowest dose effective to produce a therapeutic N effect. Such an effective dose will generally depend upon the factors described above; Generally, intravenous and subcutaneous doses of the compounds of this invention for a In CN patient, when used for the indicated analgesic effects, will range from about 0.0001 to 00 C about 100 mg per kilogram of body weight per day, more preferably from about 0.01 to N about 50 mg per kg per day, and still more preferably from about 0.1 to about 40 mg per Skg per day. For example, between about 0.01 microgram and 20 micrograms, between about 20 micrograms and 100 micrograms and between about 10 micrograms and 200 micrograms of the compounds of the invention are administered per 20 grams of subject weight.

If desired, the effective daily dose of the active compound may be administered as two, three, four, five, six or more sub-doses administered separately at appropriate intervals throughout the day, optionally, in unit dosage forms.

While it is possible for a compound of the present invention to be administered alone, it is preferable to administer the compound as a pharmaceutical composition.

5 0 for each agonist were: TNFa, 10 ng/ml; GM-CSF, 10 U/ml; and zymosan, 100 /zg/ml. Native LXA 4 specifically inhibited TNFu-induced IL-10 release (Fig. 2A), while similai amounts of IL- lp were released in the presence or absence of

LXA

4 when PMN were exposed to either GM-CSF or zymosan.

PMN were exposed to increasing concentrations of 15 R/S-methyl-LXA 4 16phenoxy-LXA 4 or native LXA 4 in the presence of TNFa (10 ng/ml) or vehicle alone. At a concentration of 100 nM, 15 R/S-methyl-LXA 4 inhibited 60 ofIL-10 release, and 16-phenoxy-LXA 4 at equimolar levels gave approximately 40% inhibition (values comparable to those obtained with native LXA 4 Time course and concentration dependence were carried out with 15 R/S-methyl

LXA

4 (Fig 2B). At 10 nM, 15 R/Smethyl-LXA 4 gave clear statistically significant inhibition, which was evident within 6 h and more prominent after 24 h (Fig. 2B). Inhibition of IL-11 by these LX analogs was, at least in part, the result of a down-regulation in gene expression, since the IL-1 3 messenger RNA levels in cells treated with TNFo (10 ng/ml) plus 15 R/S-methyl-LXA 4 (100 nM) were decreased by approximately 60 when compared to cells treated with TNFc alone (Fig. Therefore, since IL-1 P and TNFu are two cytokines that are considered important in inflammation, the inhibition of IL-11P observed (Figs. 1 2 suggested that 15 R/S-methyl-LXA 4 might exert a potent in vivo anti-cytokine action (vide infra).

0 Involvement of LXA 4 receptor To investigate whether the LXA 4 receptor (LXA 4 was involved in the O regulation of TNFa-stimulated IL- P1 release, the rabbit polyclonal antibodies against a S portion of the third extracellular domain (ASWGGTPEERLK) of LXA 4 -R prepared earlier were used (Fiore, and C.N. Serhan. 1995. Lipoxin A 4 receptor activation is distinct from that of the formyl peptide receptor in myeloid cells: inhibition of CD11/18 00 expression by lipoxin A 4 -lipoxin A4 receptor interaction. Biochemistry 34:16678-16686).

N PMN were incubated with- 50 ,g/ml of either preimmune protein-A purified IgG or IgG S directed against LXA 4 -R for 1 h at 4 °C prior to exposure to TNFc (10 ng/ml) and R/S-methyl-LXA 4 (100 nM). Anti-LXA4-R antibodies prevented IL-1 release by TNFa, suggesting that the third extracellular loop plays a crucial role in LXA 4 receptor activation (Fig. 15 R/S-methyl-LXA 4 inhibited about 50 of IL-13 release. When added together, anti-LXA 4 -R antibodies and 15R/S-methyl-LXA 4 in the presence of TNFa did not further inhibit IL- 1 appearance, and neither anti-LXA 4 -R antibodies nor 15 R/S-LXA 4 alone stimulated significant amounts of IL-1p to appear within supematants. The results of these experiments are two fold: first, they indicated that the inhibitory action of 15 R/S-methyl-LXA 4 is transduced via the LXA 4 receptor and second, that the anti-LXA 4 -R antibodies alone activate the LXA 4 receptor and lead to inhibition of IL-1 P release.

Inhibition of TNFa-directed leukocyte trafficking in vivo Since TNFa evokes leukocyte infiltration in a chemokine-dependent fashion in the murine six day air pouch, the impact of 15 R/S-methyl-LXA4 in this model was evaluated to determine whether LXA 4 or ATL also intersects the cytokine-chemokine axis in vivo (Tessier, P.H. Naccache, I. Clark-Lewis, R.P. Gladue, K.S. Neote, and S.R. McColl. 1997. Chemokine networks in vivo: involvement of C-X-C and C-C chemokines in neutrophil extravasation in vivo in response to TNF-a.

Dis. 45:873-877). 15 R/S-methyl-LXA 4 is the most subtle modification to native LXA 4 and ATL structure with addition of a methyl at carbon Murine TNFa (10 ng/ml) caused a transient infiltration of leukocytes to the air pouch in a O time-dependent fashion with maximal accumulation at 4 h. 15 R/S-methyl-LXA 4 at N nmoles inhibited the TNFa-stimulated recruitment of leukocytes to the air pouch by 62% o (Fig. Inhibition was evident at 1 h, and maximal between 2 h and 4 h. At these CN intervals, a more than 60 reduction in leukocyte infiltration was noted that remained S significantly reduced at 8 h (Fig. 5, insert). Injection of pouches with either vehicle or the m analog alone did not cause a significant leukocyte infiltration. Also, inflammatory OO exudates were collected 4 h after injection with vehicle alone, TNFa, 15 R/S-methyl-

LXA

4 alone, or TNFa plus 15 R/S-methyl-LXA 4 and cell types were enumerated. In the six-day pouches given TNFa, PMN constituted the major cell type present within the exudates at 4 h and ranged from 80 to 85% of total cell number. Administration of both R/S-methyl-LXA 4 and TNFca into the six day air pouch cavity inhibited migration of PMN and eosinophils/basophils as well as mononuclear cells (Table Of interest, administration of 15 R/S-methyl-LXA 4 alone evoked a small but statistically significant increase in mononuclear cell influx (Table a result which is consistent with earlier in vitro observations in which specific stimulation of monocyte and inhibition of PMN chemotaxis have been observed (Maddox, M. Hachicha, T. Takano, N.A. Petasis, V.V. Fokin, and C.N. Serhan. 1997. Lipoxin A 4 stable analogs are potent mimetics that stimulate human monocytes and THP-1 cells via a G-protein linked lipoxin A 4 receptor.

Cytokine-chemokine profiles Since MIP-2 is the major chemokine involved in recruiting PMN to the air pouch following injection of TNFa ,the action of 15 R/S-methyl-LXA 4 in this TNFa-induced chemokine/cytokine axis was determined. MIP-2 and IL-1 P are important proinflammatory cytokines, and IL-4, IL-10 and IL-13 possess immunomodulatory properties (Isomaki, and J. Punnonen. 1997. Pro- and anti-inflammatory cytokines in O rheumatoid arthritis. Ann. Med. 29:499-507; Volpert. T. Fong, A.E. Koch, J.D.

N Peterson, C. Waltenbaugh, R.I. Tepper, and N.P. Bouck. 1998. Inhibition of angiogenesis o by interleukin 4. J. Exp. Med. 188:1039-1046). Exudates from selected time intervals C were collected and cell-free supernatants assessed for the presence of these murine cytokines. TNFa induced maximal detectable amounts of MIP-2 and IL-1 within in minutes (not shown). 15 R/S-methyl-LXA 4 (25 nmoles) inhibited TNFa-stimulated 00 MIP-2 and IL-P1 release by 48 and 30 respectively (Fig. 15 R/S-methyl-LXA 4 alone in the air pouch did not stimulate MIP-2 or IL- P1 release. In sharp contrast, R/S-methyl-LXA 4 stimulated the appearance of IL-4 within the exudates. This Sstimulation of IL-4 was observed both in the absence as well as presence of TNFx.

Neither IL-10 nor IL-13 was detected within the pouch exudates. These results demonstrate that administration of 15 R/S-methyl-LXA 4 modified the cytokinechemokine axis in TNFa-initiated acute inflammation, and of interest this re-orientation of the cytokine-chemokine axis paralleled the reduction in leukocyte infiltration.

Several different strategies have been explored in an attempt to attenuate nondesirable action of TNFa in inflammatory diseases and ischemia/reperfusion injury including treatment of patients suffering from rheumatoid arthritis with specific Fc portion of monoclonal antibodies directed against TNFa-receptor Different steroidal and nonsteroidal drugs to alleviate the pain and the severity of inflammatory responses are extensively used (Marriott, M. Westby, and A.G. Dalgleish. 1997.

Therapeutic potential of TNF-a inhibitors old and new. DDT 2:273-282). However, certain clinical settings such as reperfusion injury are still not well controlled, and new therapeutic agents are needed. The present results indicate that LXA 4 and ATL, as evidenced by the actions of their metabolically stable analogs (16-phenoxy-LXA 4 and R/S-methyl-LXA 4 are potent cytokine-regulating lipid mediators that can also impact the course of inflammation initiated by TNFa and IL- 13. These two cytokines are considered to be key components in orchestrating the rapid inflammatory-like events in ischemia/reperfusion (within minutes to hours), and are major cytokines in rheumatoid arthritis and many other chronic diseases. Of interest, in an exudate and skin wound model, 15 R/S-methyl-LXA 4 not only inhibited the TNFa-elicited appearence of IL- 1 and MIP-2, but also concomitantly stimulated IL-4 (Figs. This represents the first observation that lipoxins induce upregulation of a potential "anti-inflammatory" cytokine -41- 0 such as IL-4. Hence, it is of particular interest that IL-4 inhibits PMN influx in acute antibody-mediated inflammation and inhibits H 2 0 2 production by IFNy-treated human o monocytes (Saleem, Z. Dai, S.N. Coelho, B.T. Konieczny, K.J.M. Assmann, F.K.

Baddoura, and F.G. Lakkis. 1998. IL-4 is an endogenous inhibitor ofneutrophil influx and subsequent pathology in acute antibody-mediated inflammation. J. Immunol.

o0 IL-4 inhibits H202 production and antileishmanial capacity of human cultured ,1 'monocytes mediated by IFN-y. J. Immunol. 143:3020-3024). IL-4 is also an active antitumor agent and most recently was shown to be a potent inhibitor of angiogenesis (Volpert, T. Fong, A.E. Koch, J.D. Peterson, C. Waltenbaugh, R.I. Tepper, and N.P. Bouck. 1998. Inhibition of angiogenesis by interleukin 4. J. Exp. Med. 188:1039- 1046). It is thus likely that the increase in IL-4 levels stimulated by metabolically stable LX analogs may mediate in part some of the in vivo impact of LXA 4 and aspirin-triggered 4 a finding that opens a new understanding of the relationship between "antiinflammatory" cytokines and lipid mediators.

In conclusion,

LXA

4 and aspirin-triggered-LXA4 appear to be involved in controlling both acute as well as chronic inflammatory responses. The results presented here support the notion that aspirin may exert in part its beneficial action via the biosynthesis of endogenous aspirin-triggered-LXA 4 that can in turn act directly on PMN and/or the appearance of IL-4. Thus, LX-ATL can protect host tissues via multi-level regulation ofproinflammatory signals.
