wherein:
R1 represents a substituted C1-C12 alkyl group; a substituted C2-C6 alkenyl group; a substituted amino group; a substituted C1-C6 alkoxy group; a substituted C1-C6 alkylthio group; a substituted carbamoyl group; a substituted sulfonamide group; or a substituted amide group;
the ring A represents a saturated cyclic alkyl group with 5 to 7 carbon atoms;
R2 represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aromatic hydrocarbon group or a substituted or unsubstituted heterocyclic group;
R3 represents a hydrogen atom, a group represented by the general formula R4O- ; or a group represented by the general formula R5(R6)N-wherein R4 represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aromatic hydrocarbon group or a substituted or unsubstituted heterocyclic group; R5 and R6 may be the same or different and each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aromatic hydrocarbon group or a substituted or unsubstituted heterocyclic group,
