N-Benzylnaltrindoles as Long-Acting .delta.-Opioid Receptor Antagonists
摘要:
The indolic nitrogen of the delta-opioid receptor antagonist, naltrindole (1), was derivatized with benzyl or substituted benzyl to afford a series (2-9) that retained delta-opioid receptor antagonist activity and selectivity in vitro. The two most potent members (2 and 8) of the series were evaluated in mice and were found to produce delta-selective antagonism of [D-Ser(2),Leu(5)] enkephalin-Thr(6) which lasted 5 days. N-Benzylnaltrindole (2) should be useful as a delta(2)-selective antagonist for in vivo studies where prolonged action is desired.
