  作为新型蛋白酶体抑制剂的氢萘醌的发现和合成

  摘要：

  筛选工作导致鉴定出 PI-8182 ( 1 )，蛋白酶体的胰凝乳蛋白酶样 (CT-L) 活性抑制剂。化合物1含有氢萘醌药效基团，其 2 位为巯基乙酸侧链，4 位为噻吩磺酰胺。开发了一种有效的氢萘醌磺酰胺支架合成路线，并在内部合成了化合物1以确认其结构和活性（IC 50 = 3.0 ± 1.6 μM [ n = 25]）。1 的新型氢萘醌衍生物被设计、合成和评估为蛋白酶体抑制剂。超过 170 种衍生物的构效关系 (SAR) 指导合成表明需要巯基乙酸侧链，并且该侧链的羧酸基团对化合物1的 CT-L 抑制活性至关重要。此外，用四唑或三唑等羧酸等排体替代羧酸可大大提高效力。在位置 2 具有硫代四唑或硫代三唑侧链的化合物，其中噻吩被疏水芳基部分取代，是最活跃的化合物，其 CT-L 抑制比化合物1（化合物15e、15f）高 20 倍, 15 小时,图15j，IC 50值在200nM左右，化合物29，IC

  Disclosed herein is the use of HLM-008182, as well as its analogues formed via in-house synthesis, as a potent proteasome inhibitors. A new method was developed for HLM-008182 through a four-step protocol and the method was further optimized to a two step protocol. The synthesis in both protocols was regioselective with TiCl 4 . The reaction was highly efficient with microwave assisted heating and THF as solvent. The modification around the molecule HLM-008182 established primary SAR, indicating that the proteasome inhibition activity was a function of the 2-side chain.

  本文披露了使用HLM-008182及其由内部合成形成的类似物作为有效的蛋白酶体抑制剂。通过四步协议开发了HLM-008182的新方法，并将该方法进一步优化为两步协议。在两种协议的合成中，都使用了TiCl4进行区域选择性反应。微波辅助加热和THF作为溶剂使反应高效。对HLM-008182分子周围的修饰建立了主要的SAR，表明蛋白酶体抑制活性是2侧链的一个功能。
