MedKoo CAT#: 510351

CAS#: 71751-77-4

Description: Meleagrin is a new FabI inhibitor from Penicillium chryosogenum. Bacterial enoyl-acyl carrier protein reductase (FabI) is a promising novel antibacterial target. Meleagrin inhibited intracellular fatty acid biosynthesis and growth of S. aureus, and increased the minimum inhibitory concentration for fabI-overexpressing S. aureus.
