A hybrid pharmacophore approach was used to design and synthesize isatin–benzothiazole analogs to examine their anti-breast cancer activity. The cytotoxicity of these compounds were determined using three different human breast tumor cell lines, MDA-MB231, MDA-MB468, MCF7, and two non-cancer breast epithelial cell lines, 184B5 and MCF10A. Although all compounds examined were quite effective on all
一种混合药效团方法被用于设计和合成伊斯汀-苯并噻唑类似物以检查其抗乳腺癌活性。使用三种不同的人乳腺肿瘤细胞系MDA-MB231,MDA-MB468,MCF7和两种非癌性乳腺上皮细胞系184B5和MCF10A确定了这些化合物的细胞毒性。尽管所检查的所有化合物对所检查的所有癌细胞系均相当有效,但化合物4-溴-1-二乙基氨基甲基-1 H-吲哚-2,3-二酮(2l)和4-氯-1-二甲基氨基甲基-3-( 6-甲基-苯并噻唑-2-ylimino)-1,3-二氢-吲哚-2-酮(5e)成为该系列中最具活性的化合物。重要的是2l的细胞毒性作用与非癌细胞相比,它的抗癌活性高10-15倍,这表明该化合物可有效控制乳腺癌,且副作用低。由于2l对MCF7细胞显示出有效的细胞毒性,并且以相似的浓度将细胞停滞在G2 / M上,因此这两种现象可能密切相关。我们得出的结论是,与isatin连接的苯并噻唑类似物可以作为原型分子,用于进一步开发新型的抗乳腺癌药物。
