development of enzyme inhibitors, was previously applied to cathepsin S to obtain low nanomolar 1,4-disubstituted-1,2,3-triazole-based aldehyde inhibitors (Wood, W. J. L.; Patterson, A. W.; Tsuruoka, H.; Jain, R. K.; Ellman, J. A. J. Am. Chem. Soc. 2005, 127, 15521-15527). Replacement of the metabolically labile aldehyde pharmacophore with the nitrile pharmacophore provided inhibitors with moderate potency
底物活性筛选方法,用于酶抑制剂开发的基于底物的片段鉴定和优化方法,先前已应用于组织蛋白酶S,以获得低纳摩尔浓度的1,4-二取代-1,2,3-三唑基醛类抑制剂( Wood,WJL; Patterson,AW; Tsuruoka,H。; Jain,RK; Ellman,JAJ Am.Chem.Soc.2005,127,15521-15527)。用腈基药效团代替代谢不稳定的醛基药效基团为抑制剂提供了对组织蛋白酶S中等效力的抑制剂。该抑制剂对组织蛋白酶B和L表现出良好的选择性,但对组织蛋白酶K则没有选择性。两种晶体形式(1.5和1)的X射线结构。
