Compounds having potent antimicrobial effects over Gram-positive bacteria and Gram-negative bacteria, high stability to β-lactamases and DHP-I and high safety for the human body and a process for producing the same.
Carbapenem compounds represented by the following general formula (I) or salts thereof:
wherein the ring A represents a 3- to 7-membered ring containing at least one nitrogen atom and optionally having a substituent other than R6; R1 represents hydrogen or methyl; R2 and R5 are the same or different and each represents hydrogen or a protecting group of the hydroxyl group; R3 represents hydrogen or a protecting group of the carboxyl group; R4 represents hydrogen, lower alkyl or a protecting group of the amino group; R6 represents: (1) hydrogen, (2) lower alkyl optionally substituted by optionally protected hydroxy, carbamoyl, formimidoyl, acetimidoyl or
wherein R7 and R8 are the same or different and each represents hydrogen, lower alkyl, or a protecting group of the amino group), or (3) a protecting group of the amino group or a protecting group of the imino group; and m is 0 or 1.
These compounds have antimicrobial effects and are useful as a drug.
