  Structure–activity relationship investigations of a potent and selective benzodiazepine oxytocin antagonist

  摘要：

  We have investigated the structure-activity relationships of the 1- and 3-substituents and replacements of the 5-phenyl roup of GW405212X 1, a potent selective oxytocin antagonist. The effect of these modifications on oxytocin binding antagonism and on pharmacokinetic parameters is reported. (C) 2001 Elsevier Science Ltd. All rights reserved.
