A series of azepanone inhibitors of cathepsin S is described. Selectivity over both cathepsin K and cathepsin L was achieved by varying the P2 substituent. Ultimately, a balanced potency and selectivity profile was achieved in compound 39 possessing a 1-methylcyclohexyl alanine at P2 and nicotinamide as the P′ substituent. The cellular potency of selected analogs is also described.
描述了一系列组织蛋白酶S的氮杂环庚烷抑制剂。通过改变P2取代基,可以实现对组织蛋白酶K和组织蛋白酶L的选择性。最终,在具有在P2处具有1-甲基环己基丙氨酸和作为P'取代基的烟酰胺的化合物39中实现了平衡的效能和选择性。还描述了所选类似物的细胞效力。
