To enhance the biostability of the ester linkage of 7-ethoxycarbonyl-4-hydroxymethyl-1(2H)-phthalazinone, which has potent biological activities, the corresponding tert-butyl ester (1e) and 7-ethoxycarbonyl-4-hydroxymethyl-6, 8-dimethyl-1(2H)-phthalazinone (EG 626) (6) were prepared. The synthesis and inhibitory effects on platelet aggregation and edematous arterial reaction of these and other closely related compounds were investigated. EG 626 appears to be a potentially effective antithrombotic and antiatherosclerotic agent.
