## Background
This application is the national stage of International Application No. PCT/IB95/00078, filed Feb. 3, 1995, designating, inter alia, the United States which is a continuation-in-part of U.S. application Ser. No. 08/209,125, filed Mar. 9, 1994, now abandoned.

This invention relates to a method of inhibiting production of TNF (tumor necrosis factor) in a mammal in need thereof which method comprises administering to said mammal an effective amount of a compound of the formula (I) (shown below) or a pharmaceutically acceptable salt thereof, which, as such are also useful in the treatment or alleviation of inflammatory conditions or disease including, but not limited to rheumatoid arthritis, osteoarthritis, asthma, bronchitis, chronic obstructive airways disease, psoriasis, allergic rhinitis, dermatitis and inflammatory bowel disease, sepsis, septic shock, tuberculosis, graft versus host disease and cachexia associated with AIDS or cancer; and this invention also relates to pharmaceutical compositions useful therefor.

TNF is produced by monocytes/macrophages and has a variety of biological activities relevant to the pathogenesis of rheumatoid arthritis (RA) and osteoarthritis (OA). Firstly, TNF can promote the accumulation of all leukocyte types by stimulating the endothelium to express adhesion molecules (T. H. Pohlman et al., J. Immunol, 136, pp. 4548-4553, 1986) and to release secondary chemotactic cytokines such as interleukin 8 (R. M. Strieter et al., Science, 243, pp. 1467-1469, 1989). Secondly, TNF can stimulate cells within the joint to synthesize and express the inducible cyclooxygenase enzyme (COX 2) and the inducible NO synthase. The products of these enzymes, prostaglandins and NO, are important mediators of pain and inflammation. Thirdly, and perhaps most importantly, TNF, like IL-1, can activate chondrocytes to degrade their own extracellular matrix and suppress synthesis of cartilage matrix components leading to cartilage destruction. In addition to these effects, TNF plays a pivotal role in the regulation of the production of other cytokines. This has been demonstrated in cultures of dissociated RA synovial cells where blocking the activity of TNF can inhibit the secretion of IL-1 (F. M. Brennan et al., Lancet, 2, pp. 244-247, 1989). Thus, blocking TNF production should prevent the synthesis of other downstream cytokines such as IL-1. Finally, TNF has been immunolocalised in both RA and OA synovial membranes(M. N. Farahat et al., Ann. Rheum. Dis., 52, pp. 870-875, 1993).

TNF is recognized to be involved in many infectious and auto-immune diseases (W. Fiers, FEBS Letters, 1991, 285, p. 199). Furthermore, it has been shown that TNF is the prime mediator of the inflammatory response seen in sepsis and septic shock (C. E. Spooner et al., Clinical Immunology and Immunopathology, 1992, 62, p. S11).

Compounds of the formula (I) wherein X.sup.1 is --(CH.sub.2).sub.q OH wherein q is 1 to 5 and R.sup.4 is alkyl having 1 to 5 carbon atoms, are synthesized by reducing the corresponding ester, wherein X.sup.1 is an alkyl ester, with diisobutylaluminum hydride (DIBAL-H) according to the following procedure. A compound of formula (I) wherein X.sup.1 is a methyl or ethyl ester, is dissolved in THF and chilled to about -78.degree. C. Approximately 2 to 4 equivalents of DIBAL-H in hexane is added to the cold THF mixture. The solution is warmed to about -30.degree. C. and then quenched with a dilute solution of HCl. The reaction is worked-up according to methods well known to those skilled in the art.

Alternatively, the compounds of formula (I) wherein X.sup.1 is hydroxymethyl and R.sup.4 is hydrogen, are synthesized by reducing a compound of formula (I) wherein X.sup.1 is an aldehyde.

Further, the compounds of formula (I) wherein X.sup.1 is 1-hydroxyalkyl (i.e., --CH(OH)alkyl) are synthesized by reducing a corresponding compound of formula (I) wherein X.sup.1 is a ketone moiety (i.e, --CO-alkyl) according to the following procedure. The corresponding ketone compound of formula (I) is dissolved in an alcoholic solvent and cooled to about 0.degree. C., to which is added sodium borohydride. The mixture is stirred until the bubbling ceases and then stirred at room temperature for approximately 1 hour. The reaction is worked-up according to methods well known to those skilled in the art.

Compounds of the formula (I) wherein X.sup.1 is hydroxy (that is when q=0) can be synthesized by dissolving the corresponding acyloxy derivative, such as when X.sup.1 is --OCOCH.sub.3, in an alcoholic solvent and treating the solution with approximately 1.1 equivalents of sodium methoxide. The reaction mixture is stirred at room temperature until the reaction is substantially complete, which is usually about 1 hour. The reaction is worked-up according to methods well known to those skilled in the art.

The compounds of the formula (I) wherein X.sup.1 is --(CH.sub.2).sub.m CON(R.sup.6)(OH) are readily synthesized by the following method. To an alcoholic solution of sodium methoxide is added an alcoholic solution of the appropriate hydroxylamine hydrochloride and a compound of the formula ##STR3## wherein X is an alkyl group and Y.sup.1, Y.sup.2, R.sup.3, R.sup.4, m and n are as defined for formula (I). The reaction mixture is stirred for about 12 to 24 hours, preferably 16 hours, at room temperature. The solvent is evaporated and the residue is worked-up according to methods well known to those skilled in the art. The intermediate ester compounds of the formula ##STR4## wherein Y.sup.1, Y.sup.2, R.sup.3, R.sup.4, m and n are as defined above for the compound of formula (I), and X is an alkyl group, are synthesized according to the following procedure. To a mixture of N-chlorosuccinimide and pyridine in an inert solvent, such as methylene chloride, is added an oxime of the formula ##STR5## wherein y.sup.1, Y.sup.2 and n are as defined above for formula (I). The mixture is allowed to stir for about 2 to 5 hours, preferably about 2 hours. A compound of the formula ##STR6## wherein R.sup.3, R.sup.4 and m are as defined above for formula I and X is an alkyl group, is added followed by the addition of triethylamine to the mixture and the mixture stirred for about 2 hours more at room temperature. The reaction is worked up according to methods well known to those skilled in the art.

Lipopolysaccharide (LPS)-Induced TNF Release From Human Monocytes

Human Peripheral Blood Monocvtes

Venous blood from healthy volunteers is collected in EDTA. Monocytes are separated by ficoll-hypaque and washed three times in complete HBSS (Hanks Balanced Salt Solution, available from GIBCO, Grand Island, N.Y.). Cells are resuspended in a final concentration of 1.3.times.10.sup.6 cells per mL in pre-warmed RPMI (available from GIBCO, Grand Island, N.Y.) (containing 5% fetal calf serum, glutamine, penicillin/streptomycin antibiotic and nystatin (all available from GIBCO, Grand Island, N.Y.)). Monocytes (1 mL/well) are allowed to adhere to a 24- well Primaria Plate (coated tissue culture plates, available from VWR Scientific, South Plainfield, N.J.) for 2 hours (37.degree. C., 5% CO.sub.2), after which time non-adherent cells are removed by gentle washing.

Incubation: Compounds are dissolved in DMSO. Each compound is tested at 4 concentrations. Fresh media (HBSS) (1.0 mL) and compound (10 .mu.L) or DMSO control is added to each well. After 1 hour at 37.degree. C., LPS (10 ng/mL final concentration) is added to appropriate wells. Plates are incubated overnight at 37.degree. C. At the end of the incubation period, 250 .mu.L of each culture supernatant is removed and duplicate 10 .mu.L samples are tested at a 1:20 dilution for TNF activity by ELISA (available from Quantikine, R&D Operations, Minneapolis, Minn.) according to the manufacturer's instructions.

TNF is determined by interpolating the average absorbance onto a standard curve. Percent inhibition is determined by the following equation: (-pg/mL TNF experimental/pg/mL TNF DMSO control!-1).times.100. IC.sub.50 is determined by linear regression of drug concentration plotted against inhibition and interpolation of the x value at y=50 using Biostat Linear Regression Program (available from Digital, Inc., Boston, Mass.).

For administration to humans to inhibit TNF in the treatment or alleviation of inflammatory conditions or disease, including but not limited to rheumatoid arthritis, osteoarthritis, asthma, bronchitis, chronic obstructive airways disease, psoriasis, allergic rhinitis, dermatitis and inflammatory bowel disease, sepsis, septic shock, tuberculosis, graft versus host disease and cachexia associated with AIDS or cancer, oral dosages of the compounds are generally in the range of from 0.1-500 mg daily for an average adult patient (70 kg). Thus for a typical adult patient, individual tablets or capsules contain from 0.1 to 50 mg of active compound, in a suitable pharmaceutically acceptable vehicle or carrier. Tablets or capsules can be given in multiple dosages to meet the dosage requirement. Dosages for intravenous administration are typically within the range of 0.1 to 10 mg per single dose as required. For intranasal or inhaler administration, the dosage is generally formulated as a 0.1 to 1% (w/v) solution. In practice the physician will determine the actual dosage which will be most suitable for an individual patient and it will vary with the age, weight and response of the particular patient. The above dosages are exemplary of the average case but there can, of course, be individual instances where higher or lower dosage ranges are merited, and all such dosages are within the scope of this invention.

For human use, the compounds of the formula (I) can be administered alone, but will generally be administered in an admixture with a pharmaceutical diluent or carrier selected with regard to the intended route of administration and standard pharmaceutical practice. For example, they may be administered orally in the form of tablets containing such excipients as starch or lactose, or in capsules or ovales either alone or in admixture with excipients, or in the form of elixirs or suspensions containing flavoring or coloring agents. They may be injected parenterally; for example, intravenously, intramuscularly or subcutaneously. For parenteral administration, they are best used in the form of a sterile aqueous solution which may contain other substances; for example, enough salts or glucose to make the solution isotonic for intravenous administration. For topical administration, they are best used in the form of solutions, lotions, ointments, salves and the like.

The following examples illustrate the synthesis of certain compounds used in the present invention. The following examples combined with the synthetic methodologies described above enable those skilled in the art to make the compounds used in the present invention.
