Acetylenic TACE inhibitors. Part 2: SAR of six-membered cyclic sulfonamide hydroxamates

The SAR of a series of potent sulfonamide hydroxamate TACE inhibitors bearing a butynyloxy P1′ group was explored. In particular, compound 5k has excellent in vitro potency against TACE enzyme and in cells, and oral activity in an in vivo model of TNF-α production and a collagen-induced arthritis model.

ACETYLENIC ALPHA-AMINO ACID-BASED SULFONAMIDE HYDROXAMIC ACID TACE INHIBITORS

Compound of the formula (B) are useful in treating disease conditions mediated by TNF- alpha , such as rheumatoid arthritis, osteoarthritis, sepsis, AIDS, ulcerative colitis, multiple sclerosis, Crohn's disease and degenerative cartilage loss.
