Abstract: Compounds according to general formula (1), and pharmaceutically acceptable salts thereof, wherein V is a covalent bond or NH, X is selected from CH2, O and N-alkyl, Z is either S or —CH═CH—, R1 and R2 are independently selected from H, F, Cl, Br and alkyl, R3 is selected from OH, O-alkyl and NR4R5, R4 and R5 are each independently H or alkyl, or together are —(CH2)q—, p is 0, 1, 2, 3 or 4, and q is 4 or 5, are new. They are agonists at the asopressin V2 receptor and are useful as antidiuretics and pro-coagulants.

Abstract: This invention provides novel compounds according to general formula (1) wherein A is a bicyclic or tricyclic azepine derivative, V1 and V2 are both H, OMe or F, or one of V1 and V2 is Br, Cl, F, OH, OMe, OBn, OPh, O-acyl, N3, NH2, NHBn or NH-acyl and the other is H, or V1 and V2 together are ═O, —O(CH2)pO— or —S(CH2)pS—; W1 is either O or S; X1 and X2 are both H, or together are ═O or ═S; Y is OR5 or NR6R7; R1, R2, R3 and R4 are independently selected from H, lower alkyl, lower alkyloxy, F, Cl and Br; R5 is selected from H and lower alkyl; R6 and R7 are independently selected from H and lower alkyl, or together are —(CH2)n; n=3, 4, 5, 6; and p is 2 or 3. The compounds are agonists at the vasopressin V2 receptor and are useful as antidiuretics and procoagulants.
