Based on the reported anticancer activity of coumarin and pyrazoline derivatives, the present investigation dealt with the design and synthesis of coumarin derivatives bearing diversely substituted pyrazoline moieties 7–10. The non-cyclic isosteres 11a–e of compounds 10a–e were synthesized for comparative reasons. The target compounds were synthesized from 8-acetyl-7-methoxycoumarin that underwent
基于所报告的香豆素和吡唑啉衍生物的抗癌活性,本调查处理香豆素衍生物轴承不同地取代的吡唑啉部分的设计和合成7 - 10。出于比较的原因,合成了化合物10a - e的非环状等排体11a - e。目标化合物是由8-乙酰基-7-甲氧基香豆素合成的,然后将其与各种醛进行Claisen-Schmidt缩合反应,得到查耳酮6a – e,然后在适当条件下与水合肼,苯肼或氨基脲反应。在体外评估合成化合物对肝HepG2细胞系的细胞毒性。化合物在纳摩尔范围内具有活性。研究了活性最高的化合物的端粒酶抑制作用和促凋亡活性。
