An imidazoline derivative or possible tautomer thereof, represented by the formula (1), wherein n represents one of integers "1" through "4", and R1 and R2 represent hydrogen atom, lower alkyl, aryl, aralkyl group, or R1 and R2 cooperate to represent alkylene, alkylidene or arylalkylidene group, while R3 represents a nitrogen-containing aromatic ring that may be substituted by lower alkyl, alkoxy or alkanoyl group, or a substituted phenyl group represented by the formula (2), wherein R4 and R5 represent hydrogen atom, lower alkyl group that may be substituted by halogen atom or hydroxyl group, cycloalkylalkyl group, lower alkenyl group, lower alkanoyl group that may be substituted by halogen atom, lower alkoxyalkyl or alkoxycarbonyl group, arylcarbonyl, arylalkyl or arylalkoxycarbonyl group, lower alkylaminocarbonyl or alkylsulfonyl group or arylsulfonyl group, or R4 and R5 cooperate with an adjacent nitrogen atom to constitute a cyclic structure, while R6 represents hydrogen atom, hydroxyl group, halogen atom, lower alkyl or alkoxy group or nitro group. <IMAGE> (1) <IMAGE> (2) |
