activity, and increased the population of apoptotic cells. Relationships between structure and biological activity were determined by the QSAR (quantitative structure activity relationships) method. Analysis of quantitative structure activity relationships allowed us to generate OPLS (Orthogonal Projections to Latent Structure) models with verified predictive ability that point out key molecular descriptors
由4-氨基-N-(芳基/杂芳基)苯磺酰胺和2,5-二甲氧基四氢呋喃合成了一系列的N-(芳基/杂芳基)-4-(1H-吡咯-1-基)苯磺酰胺。评价所有合成的化合物对HeLa,HCT-116和MCF-7人肿瘤细胞系的抗癌活性。带有8-喹啉基部分的化合物28对HCT-116,MCF-7和HeLa细胞系表现出最有效的抗癌活性,IC50值分别为3、5和7 µM。通过各种测定法分析了活性最高的化合物(28)的凋亡潜力:磷脂酰丝氨酸转运,细胞周期分布和胱天蛋白酶激活。化合物28促进了癌细胞在G2 / M期的细胞周期停滞,诱导了caspase活性,并增加了凋亡细胞的数量。结构和生物活性之间的关系是通过QSAR(定量结构活性关系)方法确定的。定量结构活性关系的分析使我们能够生成OPLS(潜在结构的正交投影)模型,该模型具有已验证的预测能力,指出了影响苯甲磺酰胺活性的关键分子描述符。
