to P2 ligands might enhance the potency of Human Immunodeficiency Virus-1 (HIV-1) protease inhibitors because of the carbonyl and amino groups promoting the formation of extensive hydrogen bonding interactions. In this work, we provide evidence that inhibitor 10e, with N-2-(2,4-Dioxo-3,4-dihydropyrimidin-1(2H)-yl) acetamide as the P2 ligand and a 4-methoxylphenylsulfonamide as the P2' ligand, displayed
将嘧啶碱基(核酸的基本成分)引入P2配体可能会增强人类免疫缺陷病毒1(HIV-1)蛋白酶抑制剂的效力,因为羰基和氨基会促进广泛的氢键相互作用的形成。在这项工作中,我们提供的证据是抑制剂10e,以N-2-(2,4-二氧代-3,4-二氢嘧啶-1(2H)-基)乙酰胺为P2配体,以4-甲氧基苯基磺酰胺为P2'配体具有显着的酶抑制和抗病毒活性,体外IC50为2.53 nM,体内对野生型HIV-1的抑制率为68%,细胞毒性低。该抑制剂还对DRV耐药的HIV-1变体表现出明显的抗病毒活性,这对进一步研究具有重要的价值。
