    摘要: Provided by the present invention are cephem derivatives represented by the general formula wherein Ar is an optionally substituted lipophilic phenyl, naphthyl or pyridyl group; L1 and L2 are (C1-C6)alkylene optionally substituted with hydroxy or oxo and/or optionally interrupted with a vinylene group, S, O, aryl, heteroaryl, in which R1 is H or (C1-C6)alkyl; A is CO2H, PO3H, SO3H, tetrazolyl or x′{circle around (−)} is a pharmaceutically acceptable anion; and Q is an quaternized nitrogen group. The derivatives are gram-positive antibacterial agents especially useful in the treatment of diseases caused by methicillin-resistant Staphylococcus aureus.
