ANTIMICROBIAL QUINOLONYL LACTAMS

摘要

Antimicrobial quinolonyl lactam compounds comprising a lactam-containing moiety linked, by a non-ester linking moiety, to the 3-carboxy group of a quinolone moiety. These compounds are of the formula; wherein (1) R3, R4, and R5, together with bonds "a" and "b", form any of a variety of lactam-containing moieties similar to those known in the art to have antimicrobial activity; (2) A, R6, R7, and R8 form any of a variety of quinolone or naphthyridine structures similar to those known in the art to have antimicrobial activity; and (3) Y, together with R5, form a variety of non-ester linking moieties between the lactam-containing moiety and the quinolone moiety.
