Some derivatives of 3-ethyl-2-mercapto-thieno[2,3-d]pyrimidin-4(3H)-ones were synthesized using ethyl 2-aminothiophene-3-carboxylates as precursors in order to estimate their cytotoxicity, respectively proliferative activity. Thienopyrimidinones containing thiosemicarbazide as well as 1,3,4-thiadiazole moieties were evaluated for their cytotoxical effect on four cancer cell lines: HT-29, breast cancer
以2-氨基噻吩-3-羧酸乙酯为前体合成了3-乙基-2-巯基噻吩并[2,3-d]嘧啶-4(3H)-的一些衍生物,以评估其细胞毒性和增殖活性。评估了含有硫代氨基脲和1,3,4-噻二唑部分的噻吩并嘧啶酮类对四种癌细胞系HT-29,乳腺癌细胞MDA-MB-231,HeLa,HepG2以及人二倍体细胞系Lep的细胞毒性作用-3。化合物5b,6a和6b对四种研究的癌细胞系显示出细胞毒性。对MDA-MB-31的最高细胞毒性显示了硫代氨基脲5b,IC50为2.31.10-4μM,但对HT-29细胞系最活跃的是噻吩并嘧啶6c,IC50为0.001μM。化合物6a表现出最高的抑制活性,IC50-0。对人肝癌HepG2细胞有99μM的毒性,对Lep3的细胞毒性低(IC50 = 191μM)。与噻二唑6b连接的噻吩并嘧啶衍生物对四种研究的癌细胞系具有毒性,尤其是对HeLa(IC50-0.83μM)具有毒性,此外该化合物在非常高的浓度89
