Previously, we discovered linomide analogues as novel HIV-1 integrase (IN) inhibitors. Here, to make possible structure–activity relationships, we report on the design and synthesis of a series of substituted dihydroquinoline-3-carboxylic acids. The crystal structure of the representative compound 2c has also been solved. Among the eight new analogues, 2e showed a potency in inhibiting IN strand transfer
以前,我们发现Linomide类似物是新型HIV-1整合酶(IN)抑制剂。在这里,为了使结构-活性关系成为可能,我们报道了一系列取代的二氢喹啉-3-羧酸的设计和合成。代表性化合物2c的晶体结构也已解决。在8种新的类似物中,2e与参考的二酮酸抑制剂L-731,988相似,具有抑制IN链转移催化活性的能力(2e的IC 50 = 0.9μMvs. 0.54μM)。和L-731,988)。此外,在两种测试的癌细胞系中,没有一种化合物显示出明显的细胞毒性。这些化合物代表了一种有趣的IN抑制剂原型,可能与金属螯合机制有关,因此有必要进一步优化。
