  Synthesis and structure–activity relationship of a novel sulfone series of TNF-α converting enzyme inhibitors

  摘要：

  Replacement of the amide functionality in IM491 (N-hydroxy-(5S,6S)-1-methyl-6-{[4-(2-methyl-4-quinolinylmethoxy)anilinyl]carbonyl}-5-piperidinecarboxamide) with a sulfonyl group led to a new series of alpha,beta-cyclic and beta,beta-cyclic gamma-sulfonyl hydroxamic acids, which were potent TNF-alpha converting enzyme (TACE) inhibitors. Among them, inhibitor 4b (N-hydroxy(4S,5S)-1-methyl-5-1[4-(2-methyl-4-quinolinylmethoxy)phenyl]sulfonylmethyl -4-pyrrolidinecarboxamide) exhibited IC50 values of <1 nM and 180 nM in porcine TACE (pTACE) and cell assays, respectively, with excellent selectivity over MMP- 1, -2, -9 and - 13 and was orally bioavailable with an F value of 46% in mice.
