1-carboxy-1-phenylmethyl group, 1-carboxypropyl group,
3-carboxypropyl group, 1-carboxy-2-ethanol group,
1-carboxy-3-propanol group, 1-carboxyethyl group,
1-carboxypentyl group, 1-carboxybutyl group or
1-carboxyheptyl group, or a group
wherein,
R3 represents a hydrogen atom; a branched chain alkyl group optionally substituted by a hydroxyl group; or a straight-chain alkyl group substituted by ethylene group, epoxy group, nitroguanidino group or by cycloalkyl group; and
B represents a formyl group, hydroxymethyl group, carboxyl group or an alkylcarboxylic acid ester group; or
R1 and R3, together with the nitrogen atom to which R' bonds and the carbon atom to which R3 bonds, form a ring structure;
with a proviso that at least one of R' and R3 represents a group other than a hydrogen atom.
