on the quinazolin-4(3H)-4-one moiety, such as 6-chloro or 6-methoxy potentially increased the cytotoxicity of the compounds. In term of caspase activation activity, several compounds were found to exhibit potent effects, (e.g. compounds 7 b, 5n, and 5l). Especially, compound 7 b activated caspases activity by almost 200% in comparison to that of PAC-1. Further docking simulation also revealed that this
抽象的 在我们寻找激活procaspase-3的新型小分子的过程中,我们设计并合成了一系列结合了quinazolin-4(3 H)-ones(5,6,7)的新型乙酰肼。生物学评估表明,八种化合物对三种人类癌细胞系(SW620,结肠癌; PC-3,前列腺癌; NCI-H23,肺癌)具有明显的细胞毒性。最有效的化合物5t的细胞毒性比5-FU高出5倍。结构-活性关系的分析表明,在喹唑啉4(3 H)-4-一部分,例如6-氯或6-甲氧基潜在地增加了化合物的细胞毒性。就胱天蛋白酶激活活性而言,发现几种化合物表现出有效的作用(例如化合物7b,5n和5l)。特别是,与PAC-1相比,化合物7b激活的胱天蛋白酶活性几乎提高了200%。进一步的对接模拟还表明,该化合物可能是有效的procaspase-3变构抑制剂。
