The novel HIV-1 integrase inhibitor 1, discovered in our laboratory, exhibits potent anti-HIV activity against a diverse set of HIV-1 isolates and also against HIV-2 and SIV. In addition, this compound displays low cellular cytotoxicity and possesses a favorable in vitro drug interaction profile with respect to isozymes of cytochrome P450 (CYP) and uridine 5′-diphospho-glucuronosyltransferase (UGT). However, the total synthesis of this significant HIV integrase inhibitor has not been reported. This contribution describes an optimized, reproducible, multi-step, synthetic route to inhibitor 1. The yield for the separate steps averaged about 80%. The methodologies utilized in the synthesis were, among others, a palladium-catalyzed cross-coupling reaction, a crossed-Claisen condensation, and a hydrazino amide synthesis step. Successful alternative synthetic methodologies for some of the steps are also described.
我们实验室发现的新型HIV-1整合酶抑制剂1,对多种HIV-1分离株、HIV-2和SIV展现出强大的抗HIV活性。此外,该化合物显示出低细胞毒性,并且在体外药物相互作用方面,对细胞色素P450(CYP)同工酶和尿苷5'-二磷酸葡萄糖醛酸基转移酶(UGT)具有良好的相互作用特征。然而,这种重要的HIV整合酶抑制剂的全合成尚未见报道。本文描述了对抑制剂1的一种优化、可重复、多步骤的合成路线。各步骤的平均产率约为80%。合成中使用的方法包括钯催化的交叉偶联反应、交叉克莱森缩合反应以及肼酰胺合成步骤。对于某些步骤,还描述了成功的替代合成方法。
