The carbapenem derivatives represented by the following formula (I) is disclosed. These compounds have strong anti-bacterial activities against bacteria including methicillin resistant Staphylococcus aureus, penicillin resistant Streptococcus pneumoniae, Enterococci, influenza, and β-lactamase producing bacteria, and have high stabilities to DHP-1.
wherein R1 represents hydrogen or methyl, either one of R2, R3, R4, or R5 represents the bond to the 2-position on the carbapenem ring, and the remaining three respectively represent hydrogen, halogen, nitro, cyano, alkyl, cycloalkyl, alkylthio, alkenyl, formyl, alkylcarbonyl, alkoxycarbonyl, aminosulfonyl, aryl carbonyl, aryl , carbamoyl, N-lower alkylcarbamoyl, N,N-di-lower alkylaminocarbonyl, lower alkoxyiminomethyl, or hydroxyiminomethyl, R6 is not present or represents alkyl, cycloalkyl, or alkenyl, and R is not present, or represents hydrogen or a group which may be metabolically hydrolyzed in the body, provided that when R6 is not present, R represents hydrogen or a group which may be metabolically hydrolyzed in the body, and when R6 is present, R is not present, and the compound forms an inner salt.
