A novel series of building blocks consisting of benzo[4,5]thiazolo[1,2-a]pyrimidine-3-carboxylate have been synthesized as potential anticancer compounds. These compounds were prepared from 2-aminobenzothiazole, benzaldehyde and ethyl acetoacetate in ethylene glycol by catalysing with TBAHS to give benzo[4,5]thiazo[1,2-a]pyrimidine derivative 4 followed by the formation of amide by reaction with several
已经合成了由苯并[4,5]噻唑并[1,2 - a ]嘧啶-3-羧酸酯组成的一系列新型结构单元,作为潜在的抗癌化合物。这些化合物是由2-氨基苯并噻唑,苯甲醛和乙酰乙酸乙酯在乙二醇中制备的,方法是用TBAHS催化生成苯并[4,5]噻唑[1,2- a ]嘧啶衍生物4,然后通过与数种仲二甲苯反应生成酰胺胺的收率很高。在体外评估了这些化合物对人类癌细胞系的细胞毒性(A549,HeLa,MDA-MB-231和MCF-7)。化合物5b对IC 50表现出有希望的细胞毒性分别针对人乳腺腺癌细胞系MCF-7和MDA-MB-231的抗药性值为0.58和1.58μM,而化合物5a对MDA-MB-231的抗细胞毒性显示为有希望的(IC 50值为5.01μM)。
