the design, synthesis, and evaluation of a structurally novel library of 20 peptidyl 3‐aryl vinyl sulfones as inhibitors of cathepsins L and B. The building blocks, described here for the first time, were synthesized in a highly efficient and enantioselective manner, starting from 3‐aryl‐substituted allyl alcohols. The corresponding vinyl sulfones were prepared by a new approach, based on a combination
本文中,我们介绍了结构肽20和肽3-芳基乙烯基砜作为组织蛋白酶L和B的抑制剂的结构新颖的文库的设计,合成和评估。本文首次描述的构建基是在高效且对映选择性的条件下合成的从3-芳基取代的烯丙醇开始 相应的乙烯基砜是通过一种新方法制备的,该方法基于使用Fmoc / t Bu策略固相肽合成的组合,然后将其固溶相偶联到相应的( R)-3-氨基-3-芳基乙烯基砜三氟乙酸盐。评价了所得化合物对组织蛋白酶L和B的抑制活性,并选择表现出最佳活性的化合物进行酶学表征。最后,进行对接研究以鉴定芳基取代基的关键结构特征。
