A series of novel phenothiazine derivatives was synthesized and tested for arginine vasopressin receptor antagonist activity.They were synthesized as novel arginine vasopressin receptor antagonists from phenothiazine as a scaffold via successive acylation,reduction and acylation reactions.Their structures were characterized by ~1H NMR,~(13)C NMR and HRMS,and biological activity was evaluated by in vitro and in vivo studies.The in vitro binding assay indicated that several compounds are potent selective V2 receptor antagonists.Compounds with promising binding affinity to V2 receptors were selected to conduct the in vivo diuretic studies on Sprague-Dawley rats.Among them.In,1r,1t and 1v exhibited excellent diuretic activity,especially 1 rand 1 v.Therefore,1r and 1v are potent novel AVPV2 receptor antagonist candidates.
