A new series of phenanthridinone derivatives, and diketo acid analogs, as well as related phenanthrene and anthracene diketo acids have been synthesized and evaluated as HIV integrase (IN) inhibitors. Several new beta-diketo acid analogs with the phenanthridinone scaffold replaced by phenanthrene, anthracene or pyrene exhibited the highest IN inhibitory potency. There is a general selectivity against
已经合成了一系列新的菲啶酮衍生物和二酮酸类似物,以及相关的菲和蒽二酮酸,并将其作为 HIV 整合酶 (IN) 抑制剂进行了评估。菲啶酮支架被菲、蒽或芘取代的几种新的 β-二酮酸类似物表现出最高的 IN 抑制效力。对整合酶链转移步骤有普遍的选择性。最有效的 IN 是 2,4-dioxo-4-phenanthren-9-yl-butyric acid (27f) 与 IC(50) 的 0.38microM 对整合酶链转移。菲二酮酸 27d-f 比相应的菲啶酮二酮酸 16 (IC(50)=65microM) 更有效 (IC(50)=2.7-0.38microM),表明菲啶酮系统中的极性酰胺桥相对于更亲脂的菲系统降低了抑制活性。这可能与化合物的芳基可能结合到整合酶活性位点的亲脂口袋上,如对接模拟所建议的。分子模型还表明活性位点 Mg(2+) 螯合的有效性有助于 IN 抑制效力。最后,一些有效的化合物抑制
