Tricyclic diazepine derivs. of formula (I) and their pharmaceutically acceptable salts, esters and pro-drugs are new. Y = (CH2)n, CH(1-3 C alkyl) or CO; AB = (CH2)mN(R3) or N(R3)(CH2)m ; n = 0-2; m = 1-2; provided that when Y = (CH2)n and n = 2, m may also be 0, and when n = 0, m may also be 3, provided also that when Y = (CH2)n and n = 2, m is not 2; R3 = COAr; Ar = substd. phenyl; opt. N-substd. indole; or opt. substd. furan, thiophene or pyrrole; D, E, F = C or N, any C atoms being opt. substd.; Z is such that the ring contg. it = opt. substd. fused phenyl; 5-membered aromatic, opt. satd. ring contg. one of O, N and S; 6-membered aromatic, opt. satd. ring contg. one N; 5- or 6-membered aromatic, opt. satd. ring contg. two N; or 5-membered aromatic, opt. satd. ring contg. one N, and either one O or one S; the heterocyclic rings are opt. substd. |
