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 TiCl4. 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及其通过内部合成形成的类似物作为有效的蛋白酶体抑制剂的方法。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。在两个协议的合成中,使用TiCl4进行区域选择性反应。在微波辅助加热和THF作为溶剂的情况下,反应非常高效。对HLM-008182分子的修饰确定了主要的SAR,表明蛋白酶体抑制活性是2-侧链的功能。
