site and displayed potent anti-vascular activity. Notably, the corresponding disodium phosphate 20b-P exhibited an excellent safety profile with the LD50 value of 599.7 mg/kg (i.v. injection), meanwhile, it significantly inhibited tumor growth and decreased microvessel density in liver cancer cell H22 allograft mouse model without obvious toxicity. Collectively, 20b and 20b-P are novel promising anti-tubulin
设计并合成了一系列新型的N-苄基苯甲酰胺衍生物作为微管蛋白聚合抑制剂。在五十一个目标化合物中,化合物20b对几种癌细胞系表现出显着的抗增殖活性,IC 50值为12至27 nM,并具有良好的血浆稳定性和令人满意的理化性质。机制研究表明20b与秋水仙碱结合位点结合并显示出有效的抗血管活性。值得注意的是,相应的磷酸氢二钠20b-P在LD 50上表现出出色的安全性在静脉注射H2O3达到599.7 mg / kg时,它显着抑制了H22同种异体移植肝癌小鼠模型中的肿瘤生长并降低了微血管密度,而没有明显的毒性。总的来说,20b和20b-P是新型的有前景的抗微管蛋白药物,具有更强的可药物性,值得进一步研究用于癌症治疗。
