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.
本发明涉及一种新型多结合化合物(药剂),其为抗菌剂。该发明的多结合化合物由2-10个配体通过连接剂或连接剂共价连接而成,其中每个单价(即未连接的)配体具有与细胞壁生物合成和代谢中的酶、合成细菌细胞壁和/或细菌细胞表面的前体有结合能力,从而干扰细胞壁的合成和/或代谢。特别地,本发明的多结合化合物由2-10个配体通过连接剂或连接剂共价连接而成,其中每个配体具有能够结合青霉素结合蛋白、横向肽酶酶、横向肽酶酶底物、β-内酰胺酶、青霉素酶、头孢菌素酶、横向转移酶酶或横向转移酶酶底物的配体结构域。优选地,配体选自β-内酰胺类或糖肽类抗菌剂。
