evaluation, and activity of a novel class of HIV protease inhibitors are described. The initial lead compounds 2 and 3 were designed by modeling replacement groups for the C-terminal Val-Val-OCH3 of a known hydroxyethylene inhibitor into the active site of the reported crystal structure of HIV protease complexed with MVT-101. The lead compound 2 was found to be a modest inhibitor with a Ki = 1.67 microM
描述了基于X射线晶体结构的设计,合成,计算评估和新型HIV蛋白酶抑制剂的活性。通过将已知羟基乙烯抑制剂的C端Val-Val-OCH3的取代基建模到已报道的与MVT-101结合的HIV蛋白酶晶体结构的活性位点中,来设计初始铅化合物2和3。发现铅化合物2是适度的抑制剂,Ki =1.67μM。解决了与HIV蛋白酶复合的化合物2的X射线晶体结构,并将其用于后续设计。发现前导化合物3是更有效的抑制剂,Ki = 0.2 microM,并且其与HIV蛋白酶复合的结构也被解析并用于后续设计。吲哚3的C-末端和N-末端的修饰均导致Ki = 30nM的化合物。以HIV蛋白酶为起点的化合物2和3的晶体结构,将热力学循环扰动分子动力学方法应用于一组选定的化合物,以便在一系列密切相关的化合物中测试此类计算的准确性。
