    Abstract:
    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 of chlorides of EA by methyl, bromide, and fluoride at 3' position remain the GSTP1-1 inhibitory effect. The compounds without any substitute at 3' position lose the activity on GSTP1-1 inhibition. These data suggest that the substitution of 3' position of EA is necessary for inhibiting GSTP1-1 activity.
