我们实验室发现的新型 HIV-1 整合酶抑制剂 1 对多种 HIV-1 分离株以及 HIV-2 和 SIV 表现出有效的抗 HIV 活性。此外,该化合物具有低细胞毒性,并且与细胞色素 P450 (CYP) 和尿苷 5'-二磷酸葡萄糖醛酸基转移酶 (UGT) 同工酶具有良好的体外药物相互作用。然而,这种重要的HIV整合酶抑制剂的全合成尚未见报道。该贡献描述了抑制剂 1 的优化、可重复、多步骤合成路线。各个步骤的产率平均约为 80%。合成中使用的方法包括钯催化的交叉偶联反应、交叉克莱森缩合和肼酰胺合成步骤。还描述了某些步骤的成功替代合成方法。
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.
