title: Opioid receptor effects of two 3-amino-2,2-dimethyltetralin analogs in guinea pig ileum longitudinal muscle.
abstract: Two substituted analogs of 3-amino-2,2-dimethyltetralin, namely 3-dimethylamino-2,2-dimethyl-7-hydroxy-1-tetralone HBr (J) and 3-dimethylamino-2,2-dimethyl-7-hydroxy-1-tetralol (MRSAL), were evaluated for opioid agonist and antagonist activity using the electrically driven guinea pig ileum longitudinal muscle preparation (GPI). Compound J appeared to be an opioid agonist with a preference for mu receptors while MRSAL was an opioid antagonist with little selectivity for mu or kappa receptors.
