urgently needed. Several recent developments indicate that the V600E mutant BRAF (BRAFV600E) is a validated target for antimelanoma‐drug development. Based on in silico screening results, a series of novel pyrazole derivatives has been designed, synthesized, and evaluated in vitro for their inhibitory activities against BRAFV600E melanoma cells. Compound 3d exhibited the most potent inhibitory activity
由于发病率不断上升且缺乏有效的治疗方法,恶性黑色素瘤是最危险的皮肤癌形式,因此迫切需要新的治疗策略。最近的几项进展表明,V600E 突变体 BRAF(BRAFV600E)是抗黑色素瘤药物开发的有效靶点。基于计算机筛选结果,设计、合成了一系列新型吡唑衍生物,并在体外评估了它们对 BRAFV600E 黑色素瘤细胞的抑制活性。化合物 3d 表现出最有效的抑制活性,对 BRAFV600E 的 IC50 值为 0.63 μM,对突变型 BRAF 依赖性细胞的 GI50 值为 0.61 μM。此外,QSAR 建模和抑制剂类似物的对接模拟为进一步的结构优化提供了重要的药效团线索。
