A variety of novel heterocyclic compounds having thienoazepine, pyrroloazepine, furoazepine, and thienodiazepine skeletons were synthesized, most of which exhibited potent antagonism of [(3)H]-AVP specific binding in assays using rat liver (V1), rat kidney (V2), human platelet plasma membranes, and recombinant human CHO cells (V2), as well as antagonizing AVP-induced hypertension in rats (V1, intravenous) and showing a diuretic effect in rats (V2, oral). By detailed studies of the structure-activity relationships of these compounds, the thienoazepine derivative 1 was found to be a very potent combined V1 and V2 antagonist. After further pharmacological and toxicological evaluation as well as physical properties, the hydrochloride 2 (JTV-605) of compound 1 was selected for clinical studies as a potent AVP antagonist with a long duration of action.
