Anthranilate sulfonamide hydroxamate TACE inhibitors. Part 2: SAR of the acetylenic P1′ group
摘要:
The SAR of a series of potent sulfonamide hydroxamate TACE inhibitors bearing novel acetylenic P1' groups was explored. In particular, compound 4t bearing a butynylox P1' moiety has excellent in vitro potency against isolated TACE enzyme and in cells, good selectivity over MMP-1 and oral activity in an in vitro model of TNF-alpha production.
