The well-known diuretic Ethacrynic acid (EA, Edecrin), showing low anti-proliferative activities, was chemically modified at different positions. The new EA derivatives have been tested in vitro in anti-proliferative assays on both tumor KB (epidermal carcinoma) and leukemia HL60 (promyelocytic) cells suitable targets for anticancer activity. Reduction of the α-β double bond of EA completely abolished
众所周知,利尿剂乙炔酸(EA,Edecrin)显示出低的抗增殖活性,已在不同位置进行了化学修饰。新的EA衍生物已在适合肿瘤细胞KB(表皮癌)和白血病HL60(早幼粒细胞)细胞的抗增殖试验中进行了体外测试。EA的α-β双键的还原完全取消了抗癌活性,而引入2-(4-取代的苯基)乙胺(系列A)或4-(4-取代的苯基)哌嗪(系列B)部分则产生了对中度至中度的抗增殖活性的化合物人类癌细胞系。在这两个部分的苯基上的几个取代是可容忍的。本研究中制备的EA衍生物的作用机理比对EA具有独特作用的谷胱甘肽S-转移酶π的抑制更为复杂,并且可能有助于克服肿瘤抵抗力。
