Ethacrynic acid (EA) is a glutathione-s-transferase pi (GSTP1-1) inhibitor. Fifteen of EA analogues were designed and synthesized and their inhibition on GSTP1-1 activity was tested in lysate of human leukemia HL-60 cells. These compounds were synthesized using substituted phenol as precursors through reacting with 2-chlorocarboxylic acid and acylation. Structure-activity analysis indicates that replacements
乙二酸(EA)是谷胱甘肽S-转移酶pi(GSTP1-1)抑制剂。设计和合成了十五种EA类似物,并在人白血病HL-60细胞的裂解物中测试了它们对GSTP1-1活性的抑制作用。这些化合物使用取代的苯酚作为前体,通过与2-氯羧酸反应并酰化而合成。结构活性分析表明,在3'位甲基,溴化物和氟化物替代EA的氯化物仍然具有GSTP1-1抑制作用。在3'位没有任何取代基的化合物失去了对GSTP1-1抑制的活性。这些数据表明,EA 3'位置的取代对于抑制GSTP1-1活性是必需的。
