title: Phenyl-substituted normethadones: synthesis and pharmacology.
abstract: Phenyl-substituted normethadone derivatives were synthesized and their affinity (IC50) for opioid receptors was determined by displacement of the specific binding sites of [3H]sufentanyl on rat brain preparations. Substitution resulted in a decrease of affinity in-vitro. These results suggest that normethadone-like compounds may interact with the P subsite of the mu-opioid receptor and that the P subsite has a well-defined cavity shape of stringent dimensions.
