Opioid Receptor Effects Of Two Aminotetralin Derivatives In Guinea Pig Ileum Longitudinal Muscle And Mouse Vas Deferens Preparations, Francisca Fatima Matos
University of the Pacific Theses and Dissertations
Two substituted analogs of 3-amino-2,2-dimethyltetralin, namely 3-dimethylamino-7-hydroxy-2,2-dimethyl-1-tetralone HBr (J) and 3-dimethylamino-7-hydroxy-2,2-dimethyl-1-tetralol (MRSAL) were evaluated for opioid agonist and antagonist activity using the electrically-stimulated guinea pig ileum longitudinal muscle and mouse vas deferens preparations. The effects of these compounds in these tissues were compared to those induced by several opioid prototype agonists at mu, kappa and delta sites (normorphine, dihydromorphine, ethylketocyclazocine, U-50,488H, beta -endorphin, dynorphin 1-13, leu-enkephalin and DADLE) and one opioid antagonist (naloxone). The results of these experiments demonstrated that compound J inhibited contractions in a concentration-dependent manner as an opioid agonist and its effects were antagonized by naloxone in …
