Derivatives of apomorphine and of N-n-propylnorapomorphine were prepared to obtain modified pharmacological activity and enhanced chemical stability. Mouse profile and dog emesis screens were performed, and the activity of various N-substituted derivatives and their esters was evaluated and compared to the parent compounds. The N-n-propyl diacetate derivative and N-methyl and N-n-propyl ascorbate salts were remarkably stable to air: apomorphine etherate was no more stable than the free base. The dimers, the major products formed during the acid-catalyzed rearrangement of morphines to apomorphines, were all potent emetics. Additionally, two showed a significant antagonism to morphine in mice and dogs.
