mechanism of their anticancer activity, compounds 5, 6, 7, 11, 13, 14, 16, 17, 19 and 22 that showed promising activity on T47D, were evaluated for their aromatase inhibitory effect. The study results disclose that the most potent aromatase inhibitors 11 and 13 showed the lowest IC50 (5.67 μM and 6.7 μM), respectively on the target enzyme. Accordingly, the apoptotic effect of the most potent compound 11 was
杂合分子用作抗癌剂,以提高效力并降低耐药性。因此,当前的研究旨在引入二十种新型的吩噻嗪磺酰胺杂种5-22、24和25,它们具有良好的抗癌活性。与参考药物(阿霉素,IC50 = 9.8μM)相比,化合物11和13显示出更强的抗癌特性(IC50 8.1和8.8μM)对人乳腺癌细胞系(T47D)。为了确定其抗癌活性的机制,评估了对T47D表现出有希望的活性的化合物5、6、7、11、13、14、16、17、19和22的芳香酶抑制作用。研究结果表明,最有效的芳香化酶抑制剂11和13在目标酶上的IC50最低(分别为5.67μM和6.7μM)。因此,与对照组相比,广泛研究了最有效的化合物11的凋亡效应,显示Bax水平显着提高至55,000倍,Bcl2的下调至5.24 * 10-4倍。此外,评估了化合物11对胱天蛋白酶3、8和9的作用,发现其水平分别提高了20、34和8.9倍,这表明内在和外在途径均被激活
