title: Structure-activity relationship investigations of a potent and selective benzodiazepine oxytocin antagonist.
abstract: We have investigated the structure-activity relationships of the 1- and 3-substituents and replacements of the 5-phenyl group of GW405212X 1, a potent selective oxytocin antagonist. The effect of these modifications on oxytocin binding antagonism and on pharmacokinetic parameters is reported.
