Description

DERIVATIVES OF ARI SULFONIL HYDROXAMIC ACID BACKGROUND OF THE INVENTION The present invention relates to arylsulfonyl hydroxamic acid derivatives which are inhibitors of matrix metalloproteinases or the production of tumor necrosis factor (TNF) and as such are useful in the treatment of a disorder selected from the group consisting of arthritis, cancer, tissue ulceration, restenosis, periodontal disease, vesicular epidermolysis, scleritis and other diseases characterized by matrix metalloproteinase activity, AIDS, septicemia, septic shock and other diseases that involve the production of TNF. In addition, the compounds of the present invention can be used in combination treatment with non-steroidal antiinflammatory drugs (hereinafter referred to as NSAIDs) and analgesics for the treatment of arthritis and, in combination with cytotoxic drugs such as adriamycin, daunomycin, cisplatin, etoposide, taxol, taxotere and alkaloids, such as vincristine, in the treatment of cancer. This invention also relates to a method of using such compounds in the treatment of the above diseases in mammals, especially humans, and to pharmaceutical compositions useful therefor.
There are a series of enzymes that produce the decomposition of structural proteins and that are structurally similar metalloproteases. Metalloproteinases that degrade the matrix, such as gelatinase, stromelysin and collagenase, are involved in the degradation of the tissue matrix (eg collagen collapses) and have been linked to many pathological disorders that involve an abnormal metabolism of connective tissue and from the basement membrane matrix, such as arthritis (e.g., osteoarthritis and rheumatoid arthritis), tissue ulceration (e.g., corneal, epidermal, and gastric ulceration), abnormal wound healing, periodontal disease, bone disease (e.g., Paget's disease and osteoporosis), tumor metastasis or tumor invasion, as well as HIV infection fj. Leuk Biol .. 52. (2): 244-248, 1992). The tumor necrosis factor is known to be involved in many infectious and autoimmune diseases (W. Fiers, FEBS Letters, 1991, 285, 199). In addition, TNF has been shown to be the primary mediator of the inflammatory response observed in septicemia and septic shock (EC, Spooner et al., Clinical Immunology and Immunopathologv, 1992, 62, S11).

Twenty-five microliters of each concentration is then added in triplicate to the appropriate wells of a 96-well Microfluor plate. The final inhibitor concentration will be a 1: 4 dilution after adding the enzyme and the substrate. The positive controls (enzyme, without inhibitor) are placed in wells D1-D6 and blanks (without enzyme, without inhibitors) are placed in wells D7-D12. Collagenase is diluted to 400 ng / ml and then added μl to the appropriate wells of the Microfluor plate. The final concentration of collagenase in the assay is 100 ng / ml The substrate (DNP-Pro-Cha-Gly-Cys (Me) -His-Ala-Lys (NMA) -NH2) is prepared as a 5mM stock solution in sulfoxide of dimethyl and then diluted to 20 μM in assay buffer. The assay is initiated by the addition of 50 μl of the well substrate of the Microfluor plate to give a final concentration of 10 μM.

Zero time is used as a target for each compound at each concentration and these values are subtracted from the data at 120 minutes. Data are plotted as concentration of inhibitor against percent control (fluorescence of the inhibitor divided by fluorescence of collagenase alone x 100). Cl50's are determined from the concentration of inhibitor that provides a signal that is 50% control. If the Cl50 described are less than 0.03 μM, then the inhibitors are tested at concentrations of 0.3 μM, 0.03 μM, 0.003 μm and 0.0003 μM.

Inhibition of TNF Production The ability of the compounds or pharmaceutically acceptable salts thereof to inhibit TNF production and, consequently, demonstrate their efficacy for the treatment of diseases involving the production of TNF is shown by the following test in vitro: Human mononuclear cells were isolated from human blood coagulated with antigen using a Ficoll-hypaque one-step separation technique. (2) The mononuclear cells were washed three times in Hanks Balanced Salt Solution (HBSS) with divalent cations and resuspended to a density of 2 x 106 / ml in HBSS containing 1% BSA. Differential counts determined using an Abbott Cell Cyn 3500 analyzer indicated that monocytes ranged from 17 to 24% of the total cells of these preparations. Aliquots were divided into 180 μl of cell suspension in 96 well plates with flat bottom (Costar). Additions of the compounds and LPS (final concentration of 100 ng / ml) yielded a final volume of 200 μl. All conditions were carried out in triplicate. After a four-hour incubation at 37 ° C in an incubator humidified with CO2, the plates were removed and centrifuged (10 minutes at approximately 250 x g) and the supernatants were removed and assayed for TNF & using the ELISA R & D kit. For administration to mammals, including humans for the inhibition of matrix metalloproteinases or production of tumor necrosis factor (TNF), a variety of conventional routes including oral, parenteral and topical can be used. In general, the active compound will be administered orally or parenterally in dosages of about 0.1 to 25 mg / kg of body weight of the patient to be treated per day, preferably of about 0.3 to 5 mg / kg. However, there will necessarily be some variation in the dosage depending on the condition of the patient in question. In any case, the person responsible for the administration will determine the appropriate dose for each patient. The compounds of the present invention can be administered in a wide range of different dosage forms. In general, the therapeutically active compounds of this invention are present in such dosage forms at concentration levels ranging from about 5.0% to about 70% in weigh. For oral administration, tablets containing various excipients such as microcrystalline cellulose, sodium citrate, calcium carbonate, dicalcium phosphate and glycine can be used, together with various disintegrants such as starch (and preferably corn starch, potato or tapioca), acid alginic and certain complex silicates, together with granulation binders such as polyvinylpyrrolidone, sucrose, gelatin and gum arabic. In addition, lubricating agents such as magnesium stearate, sodium lauryl sulfate and talc are often very useful for tabletting purposes. Solid compositions of a similar type can also be used as fillers in gelatin capsules; Preferred materials in this regard include lactose or milk sugar, as well as high molecular polyethylene glycols.
