Synthesis and antibacterial activity of new C-10 quinolonyl-cephem esters

J Antibiot (Tokyo). 1991 Feb;44(2):200-9. doi: 10.7164/antibiotics.44.200.

Abstract

A series of cephalosporins derived from cephalothin containing an ester-linked quinolonyl substituent at the C-10 position (C-10 quinolonyl-cephem esters) has been prepared and evaluated for in vitro antibacterial activity. The C-10 quinolonyl-cephem esters exhibited a broadened spectrum of activity when compared with cephalothin and the corresponding quinolones, including activity against beta-lactamase-producing bacteria.
