The HIV protease inhibitor ritonavir (RTV) is also a potent inhibitor of the metabolizing enzyme cytochrome P450 3A (CYP3A) and is clinically useful in HIV therapy in its ability to enhance human plasma levels of other HIV protease inhibitors (PIs). A novel series of CYP3A inhibitors was designed around the structural elements of RTV believed to be important to CYP3A inhibition, with general design
HIV蛋白酶抑制剂利托那韦(RTV)还是代谢酶细胞色素P450 3A(CYP3A)的有效抑制剂,在临床上可用于HIV治疗,因为它具有增强人类血浆中其他HIV蛋白酶抑制剂(PIs)水平的能力。围绕RTV的结构要素设计了一系列新的CYP3A抑制剂,这些抑制剂被认为对CYP3A抑制很重要,其一般设计特征是将模仿RTV P2-P3片段的基团连接到可溶性核心上。已发现几种类似物可强烈增强洛匹那韦(LPV)的血浆水平,其中包括8种。,与同型号的RTV相比,它具有优势。有趣的是,观察到CYP3A的体外抑制与LPV升高呈负相关。本研究中描述的化合物可能对增强被CYP3A代谢的药物的药代动力学有用。
