Abstract

It is important to understand and control the biologically active conformation in medicinal chemistry. Muraymycins and caprazamycins, which are strong inhibitors of MraY, are promising Antibacterial agents with a novel mode of action. Focusing on a sugar puckering and a dihedral angle ϕ of the uridine moiety of these Natural Products, LNA/BNA-type 5'-O-aminoribosyluridine analogues, whose puckering of the ribose moiety are completely restricted to the N-type, were designed and synthesized as simplified MraY inhibitors. Their conformation-activity relationship was further investigated in details. The conformation-activity relationship analysis investigated in this study could be a general guideline for simplification and rational drug design of MraY inhibitory nucleoside Natural Products.
