Description: 2,3-SUBSΗTUTED INDOLE COMPOUNDS AS COX-2 INHIBITORS Technical Field This invention relates to novel 2,3-substituted indoles as pharmaceutical agents. This invention specifically relates to compounds, compositions and methods for the treatment or alleviation of pain and inflammation and other inflammation-associated disorders, such as arthritis. Background Art Nonsteroidal antiinflammatory drugs (NSAIDs) are widely used in treating pain and the signs and symptoms of arthritis because of their analgesic and antiinflammatory activity. It is accepted that common NSAIDs work by blocking the activity of cyclooxygenase (COX), also known as prostaglandin G/H synthase (PGHS), the enzyme that converts arachidonic acid into prostanoids. Prostaglandins, especially prostaglandin E 2 (PGE2), which is the predominant eicosanoid detected in inflammation conditions, are mediators of pain, fever and other symptoms associated with inflammation. Inhibition of the biosynthesis of prostaglandins has been a therapeutic target of anti-inflammatory drug discovery. The therapeutic use of conventional NSAIDs is, however, limited due to drug associated side effects, including life threatening ulceration and renal toxicity. An alternative to NSAIDs is the use of corticosteriods, however, long term therapy can also result in severe side effects. Recently, two forms of COX were identified, a constitutive isoform (COX-1) and an inducible isoform (COX-2) of which expression is upregulated at sites of inflammation (Vane, J. R.; Mitchell, J. A.; Appleton, I.; Tomlinson, A.; Bishop-Bailey, D.; Croxtoll, J.;Willoughby, D. A. Proc. Natl. Acad. Sci. USA, 1994, 91, 2046). COX-1 is thought to play a physiological role and to be responsible for gastrointestinal and renal protection. On the other hand, COX-2 appears to play a pathological role and to be the predominant isoform present in inflammation conditions. A pathological role for prostaglandins has been implicated in a number of human disease states including rheumatoid and osteoarthritis, pyrexia, asthma, bone resorption, cardiovascular diseases, nephrotoxicity, atherosclerosis, hypotension, shock, pain, cancer, and Alzheimer disease. The NSAIDs currently on market inhibit both isoforms of COX with little variation for selectivity, explaining their beneficial (inhibition of COX-2) and deleterious effects (inhibition of COX-1). It is believed that compounds that would selectively inhibit the biosynthesis of prostaglandins by intervention of the induction phase of the inducible enzyme cyclooxygenase-2 and/or by intervention of the activity of the enzyme cyclooxygenase-2 on arachidonic acid would provide alternate therapy to the use of NSAIDs or corticosteriods in that such compounds would exert anti-inflammatory effects without the adverse side effects associated with COX- 1 inhibition. A variety of indole compounds are known and are disclosed in several patent applications. The International Publication Numbers WO 96/32379 discloses N- substituted indole compounds as cGMP-PDE Inhibitors. The International Publication Numbers WO 96/37467, WO 96/37469, UK Patent Publication GB 2283745 A and US Publication Number 5510368 disclose 2-methyl-N-substituted indole compounds as cyclooxygenase-2 Inhibitors.

General Synthesis A compound of general formula (I) may be prepared by any synthetic procedure applicable to structure-related compounds known to those skilled in the art. The following representative examples as described hereinafter are illustrative and are not meant to limit the scope of the invention in anyway. Unless otherwise stated, Q, X, Z, R 1 , and n are as defined above. (I) Scheme 1: In one embodiment, for example, a compound of the formula (VI) may be prepared according to the reaction sequences depicted in Scheme 1. (Compound (VI) corresponds to a compound (I) wherein R 1 is H, and Z is OH.) (V) (VI) [R 4 = H or halo] [R .5° = = C r6 alkyl] Scheme 1 In brief, a compound of formula (III) is subjected to oxidative homolytic malonylation (for leading references see J. M. Muchowski et al; Can. J. Chem., 70, 1838, 1992 and E. Baciocchi et al; J. Org. Chem., 58, 7610, 1993). In one example, a compound of the formula (III) is reacted with a suitable malonyl radical generated from a compound of formula C(R 4 )H(CO 2 R 5 )2. wherein R 4 is hydrogen or halogen, preferably chloro, and R 5 is Cμ 6 alkyl, and a manganese(III) agent, preferably manganese (III) triacetate. The manganese(III) agent is usually used in stoichiometric amounts but, alternatively, may be made catalytic by use of a suitable reoxidizing agent such as sodium persulfate, usually in the presence of a co-catalyst such as, a silver(I) salt such as silver nitrate. A preferred reaction solvent is acetic acid; however, acetic acid-acetic anhydride or other protic solvents such as propionic acid can be used. The reaction is preferably conducted in the presence of sodium acetate or potassium acetate, but, may be conducted in solvent alone. Reaction temperatures are generally in the range of room temperature (e.g., 25 °C) to reflux temperature of solvent, preferably 60 to 100 °C, but if necessary, lower or higher temperature can be employed. Reaction times are, in general, from one hour to a day, preferably from 4 to 16 hours, however shorter or longer reaction times, if necessary, can be employed. In the immediate instance, the α-acetoxy compounds of formula (IV) is usually obtained as the major product. Compounds of formula (IV) can readily be transformed to compounds of formula (V) by reduction with a suitable reducing agent, for example, a trialkylsilane, sodium α-(dimethylamino)naphtalenide, lithium in liquid ammonia, sodium naphtalenide, preferably triethylsilane in a suitable protic solvent, notably, trifluoroacetic acid. Alternatively, the reaction can be conducted in a reaction inert co-solvent such as dichloromethane or 1,2-dichloroethane. Reaction temperatures are generally in the range of room temperature to reflux temperature of solvent, preferably 15 to 100 °C, but if necessary, lower or higher temperature can be employed.

The present invention contemplates all such possible stereoisomers as well as their racemic and resolved, enantiomerically pure forms and pharmaceutically acceptable salts thereof. Certain compounds of the present invention are capable of forming addition salts with inorganic or organic acids. The pharmaceutically acceptable acid salts of the compounds of formula (I) are those which form non-toxic addition salts, such as, but not limited to, the hydrochloride, hydrobromide, sulfate or bisulfate, acetate, benzoate, besylate, citrate, fumarate, glucuronate, hippurate, lactate, tartrate, saccharate, succinate, maleate, methanesulfonate, / toluenesulfonate, phosphate and pamoate (i.e., 4,4'-methylene-t w-(3-hydroxy-2-naphthoate)) salts.

Also included within the scope of this invention are bioprecursors (also called pro-drugs) of the compounds of the formula (I). A bioprecursor of a compound of the formula (I) is a chemical derivative thereof which is readily converted back into the parent compound of the formula (I) in biological systems. In particular, a bioprecursor of a compound of the formula (I) is converted back to the parent compound of the formula (I) after the bioprecursor has been administered to, and absorbed by, a mammalian subject, e.g., a human subject. When the compounds of the formula (I) of this invention may form solvates such as hydrates, such solvates are included within the scope of this invention. An example of prodrug of the compound of formula (I) is a compound of the formula (I), wherein the 1 st position of indole ring is substituted with a group selected from hydroxymethyl, -C(O)-Cμ 4 alkyl, -C(O)-(NH 2 )CH-(C μ 4 alkyl), -C(O)-phenyl, - CH 2 NHC(O)-aryl, -CH 2 -C,- 4 alkyl-O-C(O)-C M alkyl, -d- 4 alkyl-pyridyl, -C(O)CH 2 NR 2 and -CH 2 N(Cμ 4 alkyl) 2 .

However, a dosage level that is in the range of from 0.01 mg to 10 mg per kg of body weight per day, single or divided dosage is most desirably employed in humans for the treatment of abovementioned diseases. The compounds of the present invention may be administered alone or in combination with pharmaceutically acceptable carriers or diluents by either of the above routes previously indicated, and such administration can be carried out in single or multiple doses. More particularly, the novel therapeutic agents of the invention can be administered in a wide variety of different dosage forms, i.e., they may be combined with various pharmaceutically acceptable inert carriers in the form of tablets, capsules, lozenges, trochees, hard candies, powders, sprays, creams, salves, suppositories, jellies, gels, pastes, lotions, ointments, aqueous suspensions, injectable solutions, elixirs, syrups, and the like.

Solid compositions of a similar type may also be employed as fillers in gelatine capsules; preferred materials in this connection also include lactose or milk sugar as well as high molecular weight polyethylene grycols. When aqueous suspensions and/or elixirs are desired for oral administration, the active ingredient may be combined with various sweetening or flavoring agents, coloring matter or dyes, and, if so desired, emulsifying and/or suspending agents as well, together with such diluents as water, ethanol, propylene glycol, glycerin and various combinations thereof. For parenteral administration, solutions of a compound of the present invention in either sesame or peanut oil or in aqueous propylene glycol may be employed. The aqueous solutions should be suitably buffered (preferably pH>8) if necessary and the liquid diluent first rendered isotonic. These aqueous solutions are suitable for intravenous injection purposes. The oily solutions are suitable for intra-articular, intra-muscular and subcutaneous injection purposes. The preparation of all these solutions under sterile conditions is readily accomplished by standard pharmaceutical techniques well-known to those skilled in the art. Additionally, it is also possible to administer the compounds of the present invention topically when treating inflammatory conditions of the skin and this may preferably be done by way of creams, jellies, gels, pastes, ointments and the like, in accordance with standard pharmaceutical practice.

Method for assessing biological activities: The activity of the compounds of the formula (I) of the present invention was demonstrated by the following assays. In vitro assays Human cell based COX-1 assay Human peripheral blood obtained from healthy volunteers was diluted to 1/10 volume with 3.8% sodium citrate solution. The platelet-rich plasma immediately obtained was washed with 0.14 M sodium chloride containing 12 mM Tris-HCl (pH 7.4) and 1.2 mM EDTA. Platelets were then washed with platelet buffer (Hanks buffer (Ca free) containing 0.2%> BSA and 20 mM Hepes). Finally, the human washed platelets (HWP) were suspended in platelet buffer at the concentration of 2.85 x 10 cells/ml and stored at room temperature until use. The HWP suspension (70 μl aliquots, final 2.0 x 10 7 cells/ml) was placed in a 96-well U bottom plate and 10 μl aliquots of 12.6 mM CaCte added. Platelets were incubated with A23187 (final 10 μM, Sigma) with test compound (0.1 - 100 μM) dissolved in DMSO (final concentration; less than 0.01%) at 37 °C for 15 min. The reaction was stopped by addition of EDTA (final 7.7 mM) and TxB2 in the supernatant quantitated by using a radioimmunoassay kit (Amersham) according to the manufacturer's procedure. Human cell based COX-2 assay Inhibition of COX-2 activity after induction of COX-2 by hIL-1 β The human cell based COX-2 assay was carried out as previously described (Moore et al, Inflam. Res., 45, 54, 1996). Confluent human umbilical vein endothelial cells (HUVECs, Morinaga) in a 96-well U bottom plate were washed with 100 μl of RPMI1640 containing 2% FCS and incubated with hIL-lβ (final concentration 300 U/ml, R & D Systems) at 37 °C for 24 hr. After washing, the activated HUVECs were stimulated with A23187 (final concentration 30 μM) in Hanks buffer containing 0.2% BSA, 20 mM Hepes and test compound (0.1 nM - 100 μM) dissolved in DMSO (final concentration; less than 0.01%) at 37 °C for 15 min. 6- Keto-PGFlα, stable metabolite of PGI2, in the supernatant was quantitated after adequate dilution by using a radioimmunoassay kit (Amersham) according to the manufacturer' s procedure. Inhibition of COX-2 during the induction phase Confluent human umbilical vein endothelial cells (HUVECs, Morinaga) in a 96-well U bottom plate were washed with 100 μl of RPMI1640 containing 2% FCS and test compound (0.1 nM - 100 μM) dissolved in DMSO (final concentration; less than 0.01%), and incubated with hIL-lβ (final concentration 300 U/ml, R & D Systems) at 37 °C for 24 hr. After washing, the HUVECs were stimulated with A23187 (final concentration 30 μM) in Hanks buffer containing 0.2% BSA and 20 mM Hepes at 37 °C for 15 min. 6-Keto-PGFl , a stable metabolite of PGI2, in the supernatant was quantitated after adequate dilution by using a radioimmunoassay kit (Amersham) according to the manufacturer's procedure. In vivo assays Carrageenan induced foot edema in rats Male Sprague-Dawley rats (5 weeks old, Charles River Japan) were fasted overnight. A line was drawn using a marker above the ankle on the right hind paw and the paw volume (V0) was measured by water displacement using a plethysmometer (Muromachi). Animals were given orally either vehicle (0.1 % methyl cellulose or 5% Tween 80) or a test compound (2.5 ml per 100 g body weight). One hour later, the animals were then injected intradermally with λ-carrageenan (0.1 ml of 1% w/v suspension in saline, Zushikagaku) into right hind paw (Winter et al., Proc. Soc. Exp. Biol. Med., Ill, 544, 1962; Lombardino et al, Arzneim. Forsch, 25, 1629, 1975) and three hours later, the paw volume (V3) was measured and the increase in volume (V3-V0) calculated. Since maximum inhibition attainable with classical NSAIDs is 60-70%, ED30 values were calculated. Gastric ulcer ation in rats The gastric ulcerogenicity of test compound was assessed by a modification of the conventional method (Ezer et al., J. Pharm. Pharmacol, 28, 655, 1976; Cashin et al, J. Pharm. Pharmacol, 29, 330 - 336, 1977). Male Sprague-Dawley rats (5 weeks old, Charles River Japan), fasted overnight, were given orally either vehicle (0.1%) methyl cellulose or 5% Tween 80) or a test compound (1 ml per 100 g body weight). Six hours after, the animals were sacrificed by cervical dislocation. The stomachs were removed and inflated with 1% formalin solution (10 ml). Stomachs were opened by cutting along the greater curvature. From the number of rats that showed at least one gastric ulcer or haemorrhaging erosion (including ecchymosis), the incidence of ulceration was calculated. Animals did not have access to either food or water during the experiment. Data Analysis Statistical program packages, SYSTAT (SYSTAT, INC.) and StatView (Abacus Cencepts, Inc.) for Macintosh were used. Differences between test compound treated group and control group were tested for using ANOVA. The ICso (ED3θ) values were calculated from the equation for the log-linear regression line of concentration (dose) versus percent inhibition. Some compounds prepared in the Working Examples as described herein after were tested by these methods, and showed IC 50 values of 0.001 μM to 10 μM with respect to inhibition of COX-2. Also, the above-mentioned most preferred compounds were tested by these methods, and showed IC 50 values of 0.001 μM to 0.5 μM with respect to inhibition of COX-2. COX-2 selectivity can be determined by ratio in terms of IC 50 value of COX-1 inhibition to COX-2 inhibition. In general, it can be said that a compound showing a COX-l/COX-2 inhibition ratio of more than 2 has good COX-2 selectivity. Some compounds prepared in Examples showed COX-l/COX-2 inhibition ratio of more than 10.
