In this paper we describe our structure-based ligand design, synthetic strategy, and structure-activity relationship (SAR) studies that led to the identification of thiocarbamates (TCs), a novel class of non-nucleoside reverse transcriptase inhibitors (NNRTIs), isosteres of phenethylthiazolylthiourea (PETT) derivatives. Assuming as a lead compound O-[2-(phthalimido)ethyl]phenylthiocarbamate 12, one
在本文中,我们描述了我们基于结构的配体设计,合成策略和结构与活性关系(SAR)的研究,这些研究导致了硫代氨基甲酸酯(TC)的鉴定,这是一类新型的非核苷类逆转录酶抑制剂(NNRTIs),等位基因苯乙基噻唑基硫脲(PETT)衍生物的制备。假设O- [2-(邻苯二甲酰亚胺基)乙基]苯基硫代氨基甲酸酯为先导化合物,前述酰基硫代氨基甲酸酯的前体之一(Ranise,A .;等人,J。Med。Chem。2003,46,768-781) ,通过平行合成制备了两个目标溶液相TC库。领先的优化策略导致对位取代的TC 31、33、34、39、40、41、44、45和50在纳摩尔浓度的基于MT-4的测定中对野生型HIV-1具有活性( EC50范围:0.04-0.01 microM)。最有效的同类物50(EC50 = 0。01 microM)在邻苯二甲酰亚胺部分的第4位带有一个甲基,在N-苯环的对位带有一个硝基。大
