modifications of the three molecular portions, in which 17c was notionally divided. Molecular modeling studies led to the synthesis of O-(2-phthalimidoethyl)-N-(p-substituted phenyl)-N-acylthiocarbamates, which showed in vitro activities against HIV-1 in the low nanomolar range. Nevertheless, the title compounds retained low potency against HIV-1 strains carrying mutations (K103R, Y181C, and K103N/Y181C)
描述了一系列有效的,选择性的HIV-1 N-酰基硫代氨基甲酸酯(ATC)非核苷逆转录酶抑制剂(NNRTIs)。通过高度收敛的一锅法合成标题化合物。在基于细胞的测定中,先导化合物(17c)通过8 microM的EC(50)阻止了HIV-1的繁殖。通过对三个分子部分进行单个或多个修饰来开发先导优化策略,其中在概念上将17c分为三个部分。分子模型研究导致了O-(2-邻苯二甲酰亚胺基乙基)-N-(对取代苯基)-N-酰基硫代氨基甲酸酯的合成,该化合物显示出在低纳摩尔范围内对HIV-1的体外活性。但是,标题化合物对带有引起NNRTI耐药的突变(K103R,Y181C和K103N / Y181C)的HIV-1株保持低效。从PETT衍生物与HIV-1 RT复合的X射线晶体学结构得出的RT / 17c和RT / 25c的对接模型表明,ATC的模型结构与NNRTI蝴蝶状构型不相近。对这些假晶状复合物的分析有助于合理化一些比吸收率和抵抗力数据。
