(PPIase) and inhibiting Pin1 is a potential way for discovering anti-tumor agents. With an aim to find potent Pin1 inhibitors with a novel scaffold, a series of thiazole derivatives with an alicyclic heterocycles on the 2-position were designed, synthesized and tested against human Pin1. Compound 9p bearing a 2-oxa-6-azaspiro [3,3] heptane moiety on the thiazole scaffold was identified as the most potent Pin1
PIN1是肽脯氨酰顺-反异构酶(PPI酶)和抑制PIN1是发现抗肿瘤剂的潜在方法。为了寻找具有新型支架的有效 Pin1 抑制剂,设计、合成了一系列在 2 位具有脂环族杂环的噻唑衍生物,并针对人 Pin1 进行了测试。在噻唑支架上带有 2-oxa-6-azaspiro [3,3] 庚烷部分的化合物9p被鉴定为该系列中最有效的 Pin1 抑制剂,其 IC 50值为 0.95 μM。构效关系 (SAR) 和分子模型研究表明,引入具有 H 键受体的脂环将是提高结合亲和力的可行方法。
