Abstract
NEW MATERIAL:A compound expressed by formulaI(R1 is H, lower alkyl, lower alkenyl or lower alkoxyl; R2 is H or lower alkyl: ring A is 1W12C aromatic or heterocyclic ring which may have a substituent group).
EXAMPLE: 1-[ (1-Ethyl-1,4-dihydro-7-methyl-4-oxo-1,8-naphthyridine-3-carbonyl ) l-alanyl]aminoethylphosphonic acid.
USE: An antimicrobial agent against Gram-positive and Gram-negative bacteria.
PROCESS: A carboxylic acid compound expressed by formula II, e.g. nalidixic acid, is reacted with an aminoethylphosphonic acid expressed by formula III or an ester thereof, and if necessary the ester residue is removed to give the compound expressed by formulaI.
