aryl/heteroaryl/amino/aminoarylthiazole-4-carboxamides as bacillamide analogues having structural variation at position-2 of thiazole ring. Bacillamide and its analogues were evaluated for their cytotoxic activity against three cancer cell lines (HCT-116, MDA-MD-231 and JURKAT cell lines) using colorimetric cell proliferation assay. Compounds 17a and 17b exhibited potent anti-cell proliferation activity
bacillamide(一种海洋来源的生物活性类胰蛋白酶生物碱)的十四种类似物的合成已通过高效的收敛途径完成。本无溶剂方案涉及在初始步骤中形成噻唑环,然后在2-羟基-4,6存在下,取代的2-烷基/芳基/杂芳基/氨基/氨基芳基噻唑-4-羧酸乙酯与色胺之间进行酰胺偶联。 -二甲基嘧啶,一种固相催化剂,可产生N- [2-(1 H-吲哚-3-基)乙基] -2-烷基/芳基/杂芳基/氨基/氨基芳基噻唑-4-羧酰胺作为bacillamide类似物,在噻唑环的2位具有结构变化。使用比色细胞增殖测定法评估了巴西酰胺及其类似物对三种癌细胞系(HCT-116,MDA-MD-231和JURKAT细胞系)的细胞毒活性。化合物17a和17b对这些细胞系表现出有效的抗细胞增殖活性,IC 50值分别在〜3.0μM和〜0.1-0.6μM范围内。初步的作用机制研究表明,这些化合物可启动caspase依赖性细胞凋亡。另外,化合物16d,16f,17a和17d
