<CHEM>
wherein Q is a halogen atom, a hydrogen atom, an alkyl group, an alkoxy group, an alkylsulfonyl group, an aryl group, an acetylamido group,
-@@=O
(Q1 is an alkyl group, an alkoxy group, a phenyl group, an amino group, a hydroxy group or a hydrogen atom) or
<CHEM>
(Q2, Q3 and Q4 independently are an alkyl group, an alkoxy group, a phenyl group, an acyl group, an ester group, a hydroxy group, a cyano group, a vinyl group, a halogen atom or a hydrogen atom), said alkyl group, alkoxy group, aryl group, amino group and vinyl group may have a substituent; Y1 and Y2 independently are hydrogen atom, a halogen atom, a cyano group, a hydroxy group, an alkyl group or an alkoxy group; m and n each represent an integer of 0 to 2, and m and n cannot be both 0; A represents a group represented by any one of the following formulae:
<CHEM>
wherein Z is a group of atoms necessary for constituting a substituted or unsubstituted aromatic carbon ring or an aromatic heterocyclic ring, P3 is a substituted or unsubstituted carbamoyl group or a substituted or unsubstituted sulfamoyl group, R@ is a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted amino group, a substituted or unsubstituted carbamoyl group, a carboxyl group and its ester group or a cyano group, A min is a substituted or unsubstituted aryl group, R2 and R3 independently are a substituted or unsubstituted alkyl group, a substituted or unsubstituted aralkyl group or a substituted or unsubstituted aryl group. |
