Muraymycins, novel peptidoglycan biosynthesis inhibitors: synthesis and SAR of their analogues
摘要:
A Series Of Muraymycin analogues was synthesized. These analogues showed excellent antimicrobial activity against grain-positive organisins. These analogues also showed excellent inhibitory activity against the target peptidoglycan biosynthesis enzyme MraY, the cell membrane associated transglycosylase responsible for the formation of Lipid II.

Peptide antibiotic, Leucinostatin D, was synthesized by stepwise elongation method, starting from beta-alanine t-bytyl ester. Z-octapeptide ester was converted to amide derivative and finally coupled with (4S,E)-4-methylhex-2-enoyl-L-4-methylproline.
