title: Synthesis and biological evaluation of 14-alkoxymorphinans, V: 6-Deoxyocyprodime, an opioid antagonist with decreased mu receptor selectivity in comparison to cyprodime.
abstract: N-Cyclopropylmethyl-4,14-dimethoxymorphinan (4) and N-cyclopropylmethyl-4-hydroxy-14-methoxymorphinan (5) have been prepared from cyprodime (1) by Wolff-Kishner reduction. Pharmacological studies (mouse vas deferens and guinea pig ileum preparations) revealed that there was no significant decrease of 4 in antagonist activity but in mu selectivity when compared with 1. The phenol 5 showed partial agonism at mu, kappa and delta receptors.
