In an attempt to search for clinically useful antitumor agents, we have discovered that a series of 1,7-disubstituted-6-fluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acids possessed moderate cytotoxic activity. We investigated the structure-acti

Novel arylfluoro-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid have been prepared and their antibacterial activity evaluated.These derivatives are characterized by having a fluorine atom at 6-position, substituted amino groups at the 7-position, and substituted phenyl groups at the 1-position.The in vitro antibacterial potency is greatest when the 1-substituent is either p-fluorophenyl or o,p-difluorophenyl and the 7-substituent is a 3-amino-1-pyrrolidinyl group. 1-(2,4-Difluorophenyl)-6-fluoro-7-(3-amino-1-pyrrolidinyl)-1,4-dihydro-4-oxo-1,8-naphthyridine-3-carboxylic acid (38) was found to possess excellent in vitro potency and in vivo efficacy.
