New 3,5-disubstituted-1,2,4-thiadiazoles were synthesized and together with a series of their analogs obtained earlier were tested for cytotoxic activity to breast adenocarcinoma MCF-7 and lung carcinoma A 549 cells. The selectivity of cytotoxic action was determined in comparison to etiologically noncancerous breast epithelial cells MCF-10A and lung fibroblasts VA13. From five- to six-fold selectivity of cytotoxic action was revealed for 3,4-dichlorophenyl-3-[2-(2-morpholin-4-ylethylamino)propyl]-[1,2,4]thiadiazol-5-yl}amine and (2-5-[(4-diethylami-nobenzyl)pyridin-3-ylmethylamino]-[1,2,4]thiadiazol-3-yl}-1-methylvinyl)-(2,2,6,6-tetra-methylpiperidin-4-yl)amine in the pairs A 549/VA13 and MCF-7/MCF-10A, respectively. Some structure—property relationships for the compounds under study were discussed.
合成了新的 3,5-二取代-1,2,4-噻二唑,并与之前获得的一系列类似物一起测试了对乳腺癌 MCF-7 和肺癌 A 549 细胞的细胞毒活性。与病因学上的非癌性乳腺上皮细胞 MCF-10A 和肺成纤维细胞 VA13 相比,确定了细胞毒作用的选择性。 3,4-二氯苯基-3-[2-(2-吗啉-4-基乙基氨基)丙基]-[1,2,4]噻二唑-5-基的细胞毒性作用选择性提高了五到六倍}胺和(2-5-[(4-二乙基氨基苄基)吡啶-3-基甲基氨基]-[1,2,4]噻二唑-3-基}-1-甲基乙烯基)-(2,2,6, 6-四甲基哌啶-4-基)胺分别为 A 549/VA13 和 MCF-7/MCF-10A 对。讨论了所研究化合物的一些结构-性质关系。
