propionic acid moiety as an electrophile for covalent attack by the active‐site cysteine residue of caspase 1. The syntheses of several cyanopropanate‐containing small molecules based on the optimized peptidic scaffold of prodrug VX‐765 were accomplished. These compounds were found to be potent inhibitors of caspase 1 (IC50 values ≤1 nM). Examination of these novel small molecules against a caspase panel
在此,我们研究了含腈丙酸部分作为亲电子试剂被 caspase 1 活性位点半胱氨酸残基共价攻击的潜力。基于前药 VX- 的优化肽支架,合成了几种含氰基丙酸酯的小分子。已完成 765 项。这些化合物被发现是 caspase 1 的有效抑制剂(IC 50值≤1 n M )。针对 caspase 组对这些新型小分子的检查表明,与其他 caspase 同工酶相比,它们对 caspase 1 抑制具有令人印象深刻的选择性。水解稳定性和选定的 ADME 特性的评估强调了这些药物作为研究各种环境下 caspase 1 下调(包括体内分析)的潜在有用工具。
