A series of 1- (2, 3, 4-trimethoxybenzyl) piperazine (trimetazidine) derivatives were prepared and tested for cerebral vasodilating activity. Almost all the compounds possess stronger activity than trimetazidine and among them, the γ-amino tertiary alcohols 6e-j exhibit potent cerebral vasodilating activities which are superior to those of cinnarizine and papaverine. Moreover, these compounds show a selective vasodilating effect on vertebral arteries.
