steatohepatitis (NASH). Before, we disclosed compound HMG499 as a potent HMGCR degrader, which could be a promising agent for treating CVD, however its side-effect of promoting cholesterol accumulation in cells should be eliminated before progression. Herein, a series of novel heterocyclic ring-fused analogs of HMG499 were synthesized and investigated for their activities of stimulating HMGCR degradation using
HMG-CoA还原酶(HMGCR)是胆固醇从头生物合成的限速酶,其降解可能为心血管疾病(CVD)和非酒精性脂肪性肝炎(NASH)的治疗带来治疗益处。之前,我们公开了化合物 HMG499 作为一种有效的 HMGCR 降解剂,它可能是治疗 CVD 的有前途的药物,但其促进细胞中胆固醇积累的副作用应在进展前消除。在此,合成了一系列新的 HMG499 杂环稠环类似物,并使用 HMGCR (TM1-8)-GFP 报告系统研究了它们刺激 HMGCR 降解的活性。其中,活性最高的化合物29 (QH536) 的 EC为 500.22 μM 促进 HMGCR 降解,其效力是 HMG499 (EC 50 = 0.43 μM)的约 2 倍。有趣的是,29与HMG499不同,它没有诱导细胞内胆固醇积累的副作用。机理研究表明,29可显着减少他汀类药物通过泛素化和通过泛素-蛋白酶体途径降解HMGCR蛋白诱导的HMG
