traditional small molecule drug design and are often referred to as “undruggable”. The 20S proteasome is the main protease that targets IDPs for degradation and therefore small molecule 20S proteasome enhancement presents a novel therapeutic strategy by which these undruggable IDPs could be targeted. The concept of 20S activation is still relatively new, with few potent activators having been identified
许多内在无序蛋白质 (IDP) 的聚集体或寡聚形式,包括 α-突触核蛋白,是帕
金森病和阿尔茨海默病等神经退行性疾病的标志,也是其发病机制的关键因素。由于其无序的性质,因此缺乏明确的药物结合口袋,IDPs 是传统小分子药物设计的困难目标,通常被称为“不可药物”。20S
蛋白酶体是靶向 IDP 进行降解的主要
蛋白酶,因此小分子 20S
蛋白酶体增强提供了一种新的治疗策略,通过该策略可以靶向这些不可成药的 IDP。20S 激活的概念仍然相对较新,迄今为止已确定的有效激活剂很少。在此处,我们合成并评估了一个二氢
喹唑啉类似物库,并发现了几种有前景的新型 20S
蛋白酶体激活剂。对热门歌曲的进一步测试表明,它们可以增强 20S 介导的 α-突触核蛋白降解,这是与帕
金森病相关的 IDP。
