a further structure-activity relationship (SAR) study with respect to the substituent effect of the ADK and the dimerization with conformationally constrained linkers such as piperazine, 4-amino-piperidine, piperidin-4-ol, and trans-cyclohexan-1,4-diamine. The substituents on the phenyl ring as well as the spatial orientation of the two diketo units were observed to play important roles in the IN inhibitory
芳基二酮酸(ADK)及其生物等排体是最有希望的HIV-1整合酶(IN)抑制剂。以前,我们设计了一系列ADK二聚体作为一类新的IN抑制剂,假设它们靶向IN活性位点上的两个二价金属离子。本文中,我们针对ADK的取代作用以及构象受限的连接基(例如哌嗪,4-氨基-哌啶,哌啶丁-4-醇和反式环己基-二聚体)的二聚化,提出了进一步的结构活性关系(SAR)研究。 1,4-二胺。观察到苯环上的取代基以及两个二酮单元的空间取向在IN抑制能力中起重要作用。疏水基团是在芳基环的3位上的最佳取代。哌嗪和4-氨基-哌啶连接基带来了疏水基团或卤素取代的ADK二聚体中最有效的类似物。对接研究表明,在3-苯环上的大量疏水取代和4-氨基-哌啶的连接体有利于采用一种活性构象,以实现与活性位点Mg(2+)和其中的关键残基E152的强相互作用。催化核心结构域。这项研究是我们先前关于含二聚体ADK的IN抑制剂的报告的重要扩展,为进
