at the 3-position of the 5-amino-1,2,4-triazole system. Most of the twenty-two tested compounds showed moderate to potent antiproliferative activities against a panel of solid tumor and leukemic cell lines, with four (5j, 5k, 5o and 5p) showing strong antiproliferative activity (IC50 < 1 μM) against selected cancer cells. Among them, several molecules preferentially inhibited the proliferation of leukemic
已知许多天然和合成物质会干扰微管蛋白的动态组装,从而阻止微管的形成。在我们寻找有效的和选择性的抗肿瘤剂中,合成了一系列新的1-(3',4',5'-三甲氧基苯甲酰基)-5-氨基-1,2,4-三唑。这些化合物具有不同的杂环,包括噻吩,呋喃或三个同分异构的吡啶,并且它们在5-氨基-1,2,4-三唑体系的3位上具有带电子释放或吸电子取代基的苯环。 。测试的22种化合物中的大多数对一组实体瘤和白血病细胞系均显示出中度至强效的抗增殖活性,其中4种(5j,5k,5o和5p) 对选定的癌细胞显示出强大的抗增殖活性(IC 50 <1μM)。其中,有几种分子优先抑制白血病细胞系的增殖,显示Jurkat和RS4; 11细胞的IC 50值比源自实体瘤的三系(HeLa,HT-29和MCF- 7个单元格)。化合物5k强烈抑制微管蛋白组装,IC 50值为0.66μM,是在CA-4的同时实验中获得的一半(IC 50 =
