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.

photocatalyzed, β-selective hydrocarboxylation of α,β-unsaturated esters employing CO2 radical anion generated under flow conditions was developed. A range of substrates bearing a variety of functional groups were tolerated, demonstrating chemoselectivity. A series of quaternary carboxylic acids were obtained from sterically demanding β,β-disubstituted alkenes including those derived from natural products. Mechanistic

Disclosed herein are novel dual-target compounds that bind at both the mu-opioid receptor (MOR) and dopamine D3receptors (D3R) to provide MOR-mediated analgesia, while minimizing addictive liability through D3R antagonism/partial agonism. The novel compounds are useful in the treatment of pain and substance use disorder.
