autophagy process appears as a promising target for anticancer interventions. Chloroquine (CQ) and its derivative hydroxychloroquine (HCQ) are the only FDA-approved autophagy flux inhibitors. Although diverse anticancer clinical trials are providing encouraging results, several limitations associated with the need of high dosage and long-term administration of these autophagy inhibitors are also emerging
自噬过程似乎是抗癌干预的一个有希望的目标。氯喹 (CQ) 及其衍生物羟氯喹 (HCQ) 是 FDA 唯一批准的自噬通量抑制剂。尽管各种抗癌临床试验提供了令人鼓舞的结果,但也出现了与这些自噬抑制剂需要高剂量和长期给药相关的一些限制。我们发现,抑制 REV-ERB(一种调节昼夜节律和代谢的核受体)可增强 CQ 介导的癌细胞死亡,并鉴定出一类自噬和 REV-ERB 双重抑制剂,对多种肿瘤细胞显示出体外抗癌活性高于CQ。在此,我们描述了我们的先导优化策略,该策略导致化合物24被鉴定为双重自噬和 REV-ERB 抑制剂,显示出在阻断自噬方面的改进效力、增强的对癌细胞的毒性、最佳的药物样特性以及在小鼠中的功效作为单一抗癌剂的黑色素瘤异种移植模型。
