摘要:
A carbapenem compound represented by a following formula [1], wherein R1 is C1 to C3 alkyl or C1 to C3 alkyl substituted by hydroxy. R is hydrogen atom or a group which regenerates a carboxyl group by hydrolysis in a living body, A is a following formula [1a], wherein E is a 5 to 7 membered cyclic ring optionally containing 1 to 3 hetero atoms (excluding benzene ring) which forms a bicyclic ring in corporation with the benzene ring, Y is hydrogen atom, C1 to C4 alkyl, C1 to C4 alkoxy, trifluoromethoxy, halogen atom or cyano group, or its pharmaceutically acceptable salt.
摘要:
This invention relates to novel multibinding compounds (agents) that are antibacterial agents. The multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands in their monovalent (i.e., unlinked) state have the ability to bind to a an enzyme involved in cell wall biosynthesis and metabolism, a precursor used in the synthesis of the bacterial cell wall and/or the bacterial cell surface thereby interfere with the synthesis and/or metabolism of the cell wall. In particular the multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands has a ligand domain capable of binding to penicillin binding proteins, a transpeptidase enzyme, a substrate of a transpeptidase enzyme, a beta-lactamase enzyme, pencillinase enzyme, cephalosporinase enzyme, a transglycoslase enzyme, or a transglycosylase enzyme substrate; Preferably, the ligands are selected from the beta lactam or glycopeptide class of antibacterial agents.
