在初步的分子模拟研究的基础上,表明有利的结合的“特权”片段8-羟基喹啉与IN在IN-LEDGF/p75接口,我们开发了一组修饰的8-羟基喹啉片段显示微摩尔IC 50值抑制IN-LEDGF/p75相互作用,但显着的细胞毒性与这些初始化合物。在8-羟基喹啉核心的C5和C7碳上的多样性修饰提高了效力,但是将多样性减少到仅在C5位置上的修饰最终产生具有低细胞毒性的有效抑制剂。这些特定化合物中的两种,5-((对甲苯基氨基)甲基)喹啉-8-醇和5-(3,4-二甲基苯基)氨基)甲基)喹啉-8-醇,以低微摩尔EC 50抑制MT-4细胞中的病毒复制。这是第一项为8-羟基喹啉作为IN-LEDGF/p75相互作用的新型抑制剂提供证据的研究。我们的先导化合物是药物样的,具有低分子量,并适合于各种取代,以提高其效力和选择性。
On the basis of an initial molecular modeling study suggesting the favorable binding of the “privileged” fragment 8-hydroxyquinoline with IN at the IN-LEDGF/p75 interface, we developed a set of modified 8-hydroxyquinoline fragments demonstrating micromolar IC50 values for inhibition of the IN-LEDGF/p75 interaction, but significant cytotoxicity was associated with these initial compounds. Diverse modifications at the C5 and C7 carbons of the 8-hydroxyquinoline core improved potency, but reduction of diversity to only modifications at the C5 position ultimately yielded potent inhibitors with low cytotoxicity. Two of these particular compounds, 5-((p-tolylamino)methyl)quinolin-8-ol and 5-(((3,4-dimethylphenyl)amino)methyl)quinolin-8-ol, inhibited viral replication in MT-4 cells with low micromolar EC50. This is the first study providing evidence for 8-hydroxyquinolines as novel inhibitors of the IN-LEDGF/p75 interaction. Our lead compounds are drug-like, have low molecular weights, and are amenable to various substitutions suitable for enhancing their potency and selectivity.
