Hydrazide derivatives (I) are new. Hydrazide derivatives of formula (I) and their acid or base addition salts are new. n = 0 or 1; W' = -CO- or -S(O)r; r = 0-2; Z = aryl, aralkyl, heteroaryl or heteroaralkyl (all optionally substituted with 1-5 1-6C alkyl, 1-6c alkoxy, halo, OH, 1-6C perhalogenoalkyl, nitro, 1-6C acyl, 1-6C alkylsulfonyl or amino (optionally substituted with one or two 1-6C alkyl or 1-6C acyl)); R = Z-T-CO-, Z-O-T-CO-, Z-T-O-CO- or Z-T-S(O)r; T = bond, alkylene, alkenylene or alkynylene; A = 3-8C alkylene, 3-8C alkenylene, 3-8C alkynylene, alkylenecycloalkylene, cycloalkylenealkylene, alkylenecycloalkylenealkylene, alkylenearylene, arylenealkylene, alkylenearylenealkylene or a group of formula (i); or A = forms a group of formula (ii) with the adjacent N; B1 = Z; B2 = 5 to 11-membered (un)saturated mono- or bicyclic ring optionally comprising 1-3 N, O or S; alkyl, alkylene = 1-6C; alkenylene, alkynylene = 2-6C; aryl, arylene = phenyl, naphthyl, dihydronaphthyl or tetrahydronaphthyl; heteroaryl = unsaturated or partially unsaturated 5- to 11-membered mono- or bicyclic ring containing 1-4 N,O or S; cycloalkylene = 4-8C; and provided that when n is 0, A is (i), B1 is benzyl, Z is phenyl (optionally substituted), then R is other than benzoyl. Independent claims are also included for: (1) the preparation of (I); and (2) pharmaceutical compositions comprising at leas one compound (I). |
