The present invention relates to novel quinazolin-4-one derivatives of the formula I,
wherein A is a benzo or thieno fused aromatic ring;
B is phenyl, pyridyl or pyrimidyl;
X is N or CH;
Y and Z, taken together, i.e., Y-Z, are either -CH2NH- or -NHCH2-;
R1 is selected from hydrogen, (C1-C6)alkyl optionally substituted with from one to three fluorine atoms, cyano, halo, amino, nitro and (C1-C6)alkoxy optionally substituted with from one to three fluorine atoms;
R2 is halo, cyano, (C1-C6)alkyl optionally substituted with from one to three fluorine atoms, nitro, amino, (C1-C6)alkylthio, (C1-C6)alkoxy optionally substituted with from one to three fluorine atoms, hydroxy, H-C(=O)-, (C1-C6)alkyl-O-C(=O)- or NH2-C(=O)-;
R3 and R4 are selected, independently, from hydrogen, (C1-C6)alkyl optionally substituted with from one to three fluorine atoms, halo, cyano, hydroxy (C1-C6)alkoxy optionally substituted with from one to three fluorine atoms, -C(=O)H, -CH2OR5 and -CH2NR6R7;
pharmaceutical compositions containing such compounds the use of such compounds to treat neurodegenerative, psychotropic, and drug and alcohol induced central and peripheral nervous system disorders.
