New compounds of N-substituted 2-amino-5-(2,4-dihydroxyphenyl)-1,3,4-thiadiazole set were synthesized and tested for their antiproliferative activity as part of our research in the antitumour field. Title compounds were obtained by reaction of sulfinylbis(2,4-dihydroxythiobenzoyl) (STB) with 4-substituted 3-thiosemicarbazides. The structures of compounds were identified from elemental, IR, 1H-, 13C-NMR and MS spectra analyses. The cytotoxicity in vitro against human bladder cancer HCV29T cells was determined. The most active compounds were also tested against human cancer cell lines: SW707 (rectal), A549 (lung) and T47D (breast). The antiproliferative effect of some compounds was higher than cisplatin studied comparatively.
作为抗肿瘤领域研究的一部分,我们合成了 N-取代的 2-
氨基-5-(2,4-二羟基苯基)-1,3,4-
噻二唑新化合物,并对其抗增殖活性进行了测试。标题化合物是通过亚磺酰基双(2,4-二羟基
硫代苯甲酰基)(STB)与 4-取代的 3-
硫代
氨基甲酰
肼反应得到的。通过元素、红外、1H-、13C-NMR 和 MS 光谱分析,确定了化合物的结构。在体外测定了这些化合物对人类膀胱癌 HCV29T 细胞的细胞毒性。此外,还对最具活性的化合物进行了针对人类癌
细胞系的测试:SW707(直肠癌)、A549(肺癌)和 T47D(乳腺癌)。与
顺铂相比,某些化合物的抗增殖效果更高。
