3,4-Substituted Pyrazoles for the Treatment of Inflammation

This invention is in the field of antiinflammatory pharmaceutical agents and specifically relates to compounds, compositions and methods for treating inflammation and inflammation-associated disorders, such as arthritis.

Prostaglandins play a major role in the inflammation process and the inhibition of prostaglandin production, especially production of PGG.sub.2, PGH.sub.2 and PGE.sub.2, has been a common target of antiinflammatory drug discovery. However, common non-steroidal antiinflammatory drugs (NSAIDs) that are active in reducing the prostaglandin-induced pain and swelling associated with the inflammation process are also active in affecting other prostaglandin-regulated processes not associated with the inflammation process. Thus, use of high doses of most common NSAIDs can produce severe side effects, including life threatening ulcers, that limit their therapeutic potential. An alternative to NSAIDs is the use of corticosteroids, which have even more drastic side effects, especially when long term therapy is involved.

Previous NSAIDs have been found to prevent the production of prostaglandins by inhibiting enzymes in the human arachidonic acid/prostaglandin pathway, including the enzyme cyclooxygenase (COX). Recently, the sequence of another heretofore unknown enzyme in the human arachidonic acid/prostaglandin pathway has been reported by T. Hla and K. Nielson, Proc. Natl. Acad. Sci, USA, 89, 7384 (1992) and named "cyclooxygenase II (COX II)" or "prostaglandin G/H synthase II". The discovery of an inducible enzyme associated with inflammation provides a viable target of inhibition which more effectively reduces inflammation and produces fewer and less drastic side effects. Cyclooxygenase II is inducible by cytokines or endotoxins and such induction is inhibited by glucocortoids (J. Masferrer, et al, Proc. Natl. Acad. Sci, USA, 89, 3917 (1992)). The 6-methoxy-2-napthylacetic acid metabolite of nabumetone has been found by E. Meade et al to selectively inhibit the COX II enzyme (J. Biol. Chem., 268, 6610 (1993)). In addition, Futaki et al (Prostaglandins, 47, 55 (1994)) have reported that N-(2-cyclohexyloxy-4-nitrophenyl)methanesulfonamide inhibits the COX II enzyme.

The references below that disclose antiinflammatory activity, show continuing efforts to find a safe and effective antiinflammatory agent. The novel pyrazoles disclosed herein are such safe and also effective antiinflammatory agents furthering such efforts. The invention's compounds are found to show usefulness in vivo as antiinflammatory agents with minimal side effects. The substituted pyrazolyl compounds disclosed herein preferably selectively inhibit cyclooxygenase II over cyclooxygenase I.

or a pharmaceutically-acceptable salt or prodrug thereof.

Compounds of Formula I would be useful for, but not limited to, the treatment of inflammation in a subject, and for treatment of other inflammation-associated disorders, such as, as an analgesic in the treatment of pain and headaches, or as an antipyretic for the treatment of fever. For example, compounds of Formula I would be useful to treat arthritis, including but not limited to rheumatoid arthritis, spondyloarthopathies, gouty arthritis, osteoarthritis, systemic lupus erythematosus and juvenile arthritis. Such compounds of Formula I would be useful in the treatment of asthma, bronchitis, menstrual cramps, tendinitis, bursitis, and skin related conditions such as psoriasis, eczema, burns and dermatitiso Compounds of Formula I also would be useful to treat gastrointestinal conditions such as inflammatory bowel disease, Crohn's disease, gastritis, irritable bowel syndrome and ulcerative colitis and for the prevention of colorectal cancer. Compounds of Formula I would be useful in treating inflammation in such diseases as vascular diseases, migraine headaches, periarteritis nodosa, thyroidiris, aplastic anemia, Hodgkin's disease, sclerodoma, rheumatic fever, type I diabetes, myasthenia gravis, sarcoidosis, nephrotic syndrome, Behcet's syndrome, polymyositis, gingivitis, hypersensitivity, conjunctivitis, swelling occurring after injury, myocardial ischemia, and the like.

The compounds of the invention can be synthesized according to the following procedures of Schemes I-VI, wherein the R.sub.1 -R.sup.5 substituents are as defined for Formula I, above, except where further noted. ##STR4##

Scheme I shows the procedure for forming substituted aryl ketones 2, where R.sup.2 is phenyl substituted with R.sup.5 --S-- where R.sup.5 is alkyl, from the corresponding aryl sulfides 1. Sulfides 1, such as thioanisole, are reacted with a substituted acetic acid, such as a phenyl or cycloalkylacetic acid, under Lewis acid catalyzed conditions, preferably using polyphosphoric acid (PPA) as the Lewis acid, to provide phenyl ketone 2. ##STR5##

Scheme II shows the four step procedure for forming pyrazoles 5 of the present invention (where R.sup.5 is alkyl) from ketones 2. In step 1, ketone 2 is reacted with a base, such as lithium bis(trimethylsilyl)amide or lithium diisopropylamide (LDA) to form the anion. In step 2, the anion is reacted with an acetylating reagent, preferably 1-trifluoroacetylimidazole or 1-difluoroacetylimidazole, provides diketone 3. In step 3, the reaction of diketone 3 with hydrazine or a substituted hydrazine, gives pyrazole 4. In step 4, the pyrazole 4 is oxidized with an oxidizing reagent, such as Oxone.RTM. (potassium peroxymonosulfate), 3-chloroperbenzoic acid (MCPBA) or hydrogen peroxide, to give a mixture of the desired 3-(alkylsulfonyl)phenyl-pyrazole 5 and the 5-(alkylsulfonyl)phenyl-pyrazole isomer. The desired pyrazole 5, usually a white or pale yellow solid, is obtained in pure form either by chromatography or recrystallization.

Alternatively, diketone 3 can be formed from ketone 2 by treatment with a base, such as sodium hydride, in a solvent, such as dimethylformamide, and further reacting with a nitrile to form an aminoketone. Treatment of the aminoketone with acid forms the diketone 3. ##STR6##

Scheme III shows an alternative two step synthesis of pyrazole analogs 7 where R.sup.1 is hydrogen. In Step 1, ketone 2, prepared as described in Scheme I, is heated (100.degree.-120.degree. C.) with a formamide equivalent, such as DMF-dimethyl acetal, either neat or in DMF to provide enamino-ketone 6. In Step 2, the reaction of enamino-ketone 6 with hydrazine gives the desired pyrazole 7. ##STR7##

Scheme IV shows a procedure for forming the 3-(alkylsulfonyl)phenyl-pyrazoles 8 of the present invention as well as an alternate synthesis of the desired 3-(alkylsulfonyl)phenyl-1-substituted pyrazoles 5 from pyrazoles 7-(where R.sup.1 is hydrogen). In step 1, the pyrazole 7 is oxidized with an oxidizing reagent, such as Oxone.RTM. (potassium peroxymonosulfate), 3-chloroperbenzoic acid (MCPBA) or hydrogen peroxide to form the desired 3-(alkylsulfonyl)phenyl-pyrazoles 8. In step 2, the reaction of 3-(alkylsulfonyl)phenyl-pyrazoles 8 with a variety of alkylating reagents, such as an alkyl halide, in the presence of a base, such as K.sub.2 CO.sub.3, in a polar aprotic solvent such as DMF, gives a mixture of the desired 3-(alkylsulfonyl)phenyl-1-substituted pyrazole 5 and the 5-(alkylsulfonyl)phenyl-pyrazole isomer. The desired pyrazole 5 is purified, such as by chromatography or recrystallization. ##STR8##

Scheme V shows an alternate method for preparing antiinflammatory pyrazoles with various R.sup.4 substituents. In Step 1, pyrazoles 9, where R.sup.4 is an ester, (where R is alkyl and n is 0 to 6) are converted to the corresponding acids 10 by saponification, preferably with sodium hydroxide or lithium hydroxide. In Step 2, the acids 10 can be converted into the amides 11 (where R' and R" are hydrogen or alkyl) by standard peptide amino acid coupling conditions (M. Bodanszky and A. Bodanszky, Practice of Peptide Synthesis (1984)) involving conversion of the acid 10 into an activated ester or amide (i.e with carbonyl diimidazole), followed by coupling with an amine. Amides 11 can additionally be prepared using Weinreb trimethyl aluminum conditions (Tetrahedron Lett., 18, 4171 (1977)) on ester 9. When the amide 11 is unsubstituted (when R.sup.6 and R.sup.7 are hydrogen), the nitrile 12 can be obtained by dehydration. ##STR9##

Synthetic Scheme VI shows the three step procedure used to prepare sulfonamide antiinflammatory agents 14 from their corresponding methylsulfones 13. In step one, a THF solution of the methylsulfones 13 at -78.degree.

Rat Carrageenan Foot Pad Edema Test

The carrageenan foot edema test was performed with materials, reagents and procedures essentially as described by Winter, et al., (Proc. Soc. Exp. Biol. Med., 111, 544 (1962)). Male Sprague-Dawley rats were selected in each group so that the average body weight was as close as possible. Rats were fasted with free access to water for over sixteen hours prior to the test. The rats were dosed orally (1 mL) with compounds suspended in vehicle containing 0.5% methylcellulose and 0.025% surfactant, or with vehicle alone. One hour later a subplantar injection of 0.1 mL of 1% solution of carrageenan/sterile 0.9% saline was administered and the volume of the injected foot was measured with a displacement plethysmometer connected to a pressure transducer with a digital indicator. Three hours after the injection of the carrageenan, the volume of the foot was again measured. The average foot swelling in a group of drug-treated animals was compared with that of a group of placebo-treated animals and the percentage inhibition of edema was determined (Otterness and Bliven, Laboratory Models for Testing NSAIDs, in Non-Steroidal Anti-Inflammatory Drugs, (Jo Lombardino, ed. 1985)). The % inhibition shows the % decrease from control paw volume determined in this procedure and the data for selected compounds in this invention are summarized in Table 1.

Rat Carrageenan-induced Analgesia Test

The analgesia test using rat carrageenan was performed with materials, reagents and procedures essentially as described by Hargreaves, et al., (Pain, 32, 77 (1988)). Male Sprague-Dawley rats were treated as previously described for the Carrageenan Foot Pad Edema test. Three hours after the injection of the carrageenan, the rats were placed in a special plexiglass container with a transparent floor having a high intensity lamp as a radiant heat source, positionable under the floor. After an initial twenty minute period, thermal stimulation was begun on either the injected foot or on the contralateral uninjected foot. A photoelectric cell turned off the lamp and timer when light was interrupted by paw withdrawal. The time until the rat withdraws its foot was then measured. The withdrawal latency in seconds was determined for the control and drug-treated groups, and percent inhibition of the hyperalgesic foot withdrawal determined, Results are shown in Table I.

Evaluation of COX I and COX II activity in vitro

The compounds of this invention exhibited inhibition in vitro of COX II. The COX II inhibition activity of the compounds of this invention illustrated in the Examples was determined by the following methods.

a. Preparation of recombinant COX baculoviruses

A 2.0 kb fragment containing the coding region of either human or murine COX-I or human or murine COX-II was cloned into a BamH1 site of the baculovirus transfer vector pVL1393-(Invitrogen) to generate the baculovirus transfer vectors for COX-I and COX-II in a manner similar to the method of D. R. O'Reilly et al (Baculovirus Expression Vectors: A Laboratory Manual (1992)). Recombinant baculoviruses were isolated by transfecting 4 .mu.g of baculovirus transfer vector DNA into SF9 insect cells (2.times.10e8) along with 200 ng of liberalized baculovirus plasmid DNA by the calcium phosphate method. See M. D. Summers and G. E. Smith, A Manual of Methods for Baculovirus Vectors and Insect Cell Culture Procedures, Texas Agric. Exp. Station Bull. 1555 (1987). Recombinant viruses were purified by three rounds of plaque purification and high titer (10E7-10E8 pfu/ml) stocks of virus were prepared. For large scale production, SF9 insect cells were infected in 10 liter fermentors (0.5.times.10.sup.6 /ml) with the recombinant baculovirus stock such that the multiplicity of infection was 0.1. After 72 hours the cells were centrifuged and the cell pellet homogenized in Tris/Sucrose (50 mM: 25%, pH 8.0) containing 1% 3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate (CHAPS). The homogenate was centrifuged at 10,000.times.G for 30 minutes, and the resultant supernatant was stored at -80.degree. C. before being assayed for COX activity.

b. Assay for COX I and COX II activity:

COX activity was assayed as PGE.sub.2 -formed/.mu.g protein/time using an ELISA to detect the prostaglandin released. CHAPS-solubilized insect cell membranes containing the appropriate COX enzyme were incubated in a potassium phosphate buffer (50 mM, pH 8.0) containing epinephrine, phenol, and heme with the addition of arachidonic acid (10 .mu.M). Compounds were pre-incubated with the enzyme for 10-20 minutes prior to the addition of arachidonic acid. Any reaction between the arachidonic acid and the enzyme was stopped after ten minutes at 37.degree. C./room temperature by transferring 40 .mu.l of reaction mix into 160 .mu.l ELISA buffer and 25 .mu.M indomethacin. The PGE.sub.2 formed was measured by standard ELISA technology (Cayman Chemical). Results are shown in Table II.
