the effects of benzylic hydroxyl substitution on the activity of a close structural analog of clonidine was assessed at alpha 1- and alpha 2-adrenoreceptors both in vitro and in vivo in order to uncover possible differences that this substitution may have on the effects of imidazolines and phenethylamines at adrenoreceptors .
