RESUMEN
Synthesis and structure-activity relationships (SAR) of a novel series of vasopressin V(1b) (V(3)) antagonists are described. 2-(4-Oxo-2-aryl-quinazolin-3(4H)-yl)acetamides have been identified with low nanomolar affinity for the V(1b) receptor and good selectivity with respect to related receptors V(1a), V(2) and oxytocin (OT). Optimised compound 12j demonstrates a good pharmacokinetic profile and activity in a mechanistic model of HPA dysfunction.

The profile of a series of triazine and pyrimidine based ROCK inhibitors is described. An initial binding mode was established based on a homology model and the proposed interactions are consistent with the observed SAR. Compounds from the series are potent in a cell migration assay and possess a favorable kinase selectivity. In vivo activity was demonstrated for compound 1A in a spontaneous hypertensive rat model.
