melanoma. Inhibiting translation by stabilizing the G-quadruplex (G4) structure with small molecules seems to be a potential strategy for cancer therapy due to the NRAS protein's lack of a druggable pocket. To enhance the effects of previously reported G4 stabilizers quindoline derivatives, we designed and synthesized a novel series of quindoline derivatives with fork-shaped side chains by introducing (alkylamino)alkoxy
突变是皮肤黑色素瘤中第二常见的致癌因素。由于 NRAS 蛋白缺乏可药物口袋,通过用小分子稳定 G 四链体 (G4) 结构来抑制翻译似乎是癌症治疗的潜在策略。为了增强先前报道的G4稳定剂喹啉衍生物的效果,我们通过引入(烷基氨基)烷氧基侧链,设计并合成了一系列具有叉形侧链的新型喹啉衍生物。一系列实验结果表明,引入叉形(烷基氨基)烷氧基侧链可以增强配体对RNA G四链体的稳定能力及其抗黑色素瘤活性。其中一种化合物在突变黑色素瘤异种移植小鼠模型中表现出良好的抗肿瘤活性,显示了此类化合物的治疗潜力。
