4-amidofuran-3-one inhibitors of cathepsin S are described. The synthesis and structure–activity relationship of a series of inhibitors with a sulfonamide moiety in the P3 position is presented. Several members of the series show sub-nanomolar inhibition of the target enzyme as well as an excellent selectivity profile and good cellular potency. Molecular modeling of the most interesting inhibitors describes
描述了组织蛋白酶S的高效和选择性的4-氨基呋喃-3-酮抑制剂。介绍了一系列在P3位置带有磺酰胺部分的抑制剂的合成及其构效关系。该系列的几个成员显示出对目标酶的亚纳摩尔抑制作用以及出色的选择性和良好的细胞效能。最有趣的抑制剂的分子模型描述了扩展S3口袋中的相互作用,并解释了观察到的对组织蛋白酶K的选择性。
