A series of ethacrynic acid (2-[2,3-dichloro-4-(2-methylidenebutanoyl)phenoxy]acetic acid) (EA, Edecrin) containing sulfonamides linked via three types of linkers namely 1,2-ethylenediamine, piperazine and 4-aminopiperidine was synthesized and subsequently evaluated in vitro against HL60 and HCT116 cancer cell lines. All the EA analogs, excluding 6a and 6c, showed anti-proliferative activity with IC50s
一系列的乙炔酸(2- [2,3-二氯-4-(2-亚甲基亚丁基丁酰基)苯氧基]乙酸)(EA,Edecrin),含有通过三种类型的接头连接的磺酰胺,即1,2-乙二胺,哌嗪和4合成β-氨基哌啶,随后在体外针对HL60和HCT116癌细胞系进行评估。除6a和6c外,所有EA类似物均具有抗增殖活性,IC 50s处于微摩尔范围(小于4 uM)。三个导数6b,7b和7e选择它们在HL60细胞系中具有有趣的双重活性,以便进一步针对一组癌细胞系(HCT116,A549,MCF7,PC3,U87-MG和SKOV3)以及在作为正常细胞系的MRC5上进行评估。这些化合物显示出针对A549,MCF7,PC3和HCT116细胞系的纳摩尔浓度的IC 50值,从而得出以下发现:哌嗪或4-氨基哌啶是开发具有高达24 nM的强抗增殖活性的EA类似物的最佳选择。。此外,就选择性而言,那些接头更适合提供高达63.8的安全系数。
