Synthesis and SAR studies of novel 2-(6-aminomethylaryl-2-aryl-4-oxo-quinazolin-3(4H)-yl)acetamide Vasopressin V1b receptor antagonists

Synthesis and structure–activity relationships (SAR) of a novel series of vasopressin V1b antagonists are described. 2-(6-Aminomethylaryl-2-aryl-4-oxo-quinazolin-3(4H)-yl)acetamide have been identified with low nanomolar affinity for the V1b receptor and good selectivity with respect to related receptors V1a, V2 and OT. Optimised compound 16 shows a good pharmacokinetic profile and activity in a mechanistic model of HPA dysfunction.
