potency against the HIV protease in vitro. Within this series, 31 (VLE776) is the most effective inhibitor against FIV protease, and it contains Phe at P3, but no P3' residue. VLE776 also exhibited potent antiviral activities against the drug-resistant HIV mutants (G48V and V82F) and the TL3-resistant HIV mutants. Explanation of the inhibition activities was described. In addition, a new strategy was described
已使用不对称竞争抑制剂研究了P1和P3侧链与HIV和FIV蛋白酶的结合的S1和S3疏水亚位的相互作用。所评估的抑制剂含有(2S,3S)-3-氨基-2-羟基-4-苯基丁酸(allophenylnorstatine)为羟甲基羰基等排酮,(R)-5,5-二甲基-1,3-噻唑烷-4-羰基为P1',Val为P2和P2'残基,以及P3和P3'位置的各种氨基酸。在体外,所有抑制剂均显示出对两种酶的竞争性抑制,对HIV蛋白酶的抑制力更高。在这个系列中,31(VLE776)是最有效的FIV蛋白酶抑制剂,它在P3处含有Phe,但没有P3'残基。VLE776还表现出了对耐药HIV突变体(G48V和V82F)和TL3耐药HIV突变体的有效抗病毒活性。描述了抑制活性。另外,描述了开发双功能抑制剂的新策略,该双功能抑制剂将蛋白酶抑制剂和另一种酶抑制剂结合在一个分子中。
