Platensimycin

Description: Platensimycin (PTM) is an antibiotic produced by S. platensis that inhibits Gram-positve bacteria by selectively inhibiting cellular lipid biosynthesis (IC50 = 0.1 µM). It targets the beta-ketoacyl-acyl-carrier-protein synthase I/II, FabF/B, an enzyme that participates in the biosynthesis of fatty acids (IC50s = 48 and 160 nM for S. aureus and E. coli enzymes, respectively). By specifically targeting fatty acid synthesis in bacteria, PTM is thought to be a promising agent for overcoming antibiotic resistance. PTM is also a selective inhibitor of the mammalian fatty acid synthase and has been shown to reduce liver triglyceride levels and to improve insulin sensitivity in a diabetic mouse model after an oral dose of 30 mg/kg.
