  • Patent number: 7560454
    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. The invention further comprises pharmaceutical compositions incorporating these vasopressin agonists, which compositions are particularly useful in the treatment of central diabetes insipidus, nocturnal enuresis and nocturia.
