rationally-design, synthesize, characterize, biologically evaluate, and to elucidate the anticancer mechanism of action of a novel analogue of noscapine, N-propargyl noscapine (NPN), as a potential drug candidate against triple-negative breast cancer (TNBC). After the synthesis and IR, H, C NMR and mass spectral characterization of NPN, its antiproliferative efficacy against different cancer cell lines
目标 为了合理地设计,合成,表征,生物学评估和阐明新型的Noscapine类似物N-炔丙基Noscapine(NPN)作为抗三阴性乳腺癌(TNBC)的潜在候选药物的抗癌机制。 材料和方法 NPN的合成,IR,1 H,13 C NMR和质谱表征后,研究了其对乳腺癌(MCF-7和MDA-MB-231),肺癌(HOP-62和A- 549)和非癌性上皮细胞系(VERO),使用磺基罗丹明B测定法。使用流式细胞仪分析细胞周期进程。使用色氨酸猝灭测定,ANS结合测定和秋水仙碱结合测定研究药物-微管蛋白相互作用。免疫荧光用于检查NPN对细胞微管的影响。分别使用DCFDA,若丹明123和a啶橙/溴化乙锭对细胞进行染色,研究了活性氧(ROS),线粒体膜电位(MMP)损失和细胞死亡的水平。 主要发现 NPN强烈抑制活力(IC 50,1.35±0.2μM)和克隆发生(IC 50的TNBC细胞系,MDA-MB-231的,0
