Platencin

Platencin is a natural, broad spectrum Gram-positive antibiotic isolated from S. platensis, which is also the source of platensimycin (Cay-15507). Platencin inhibits two key enzymes in bacterial fatty acid synthesis, beta-ketoacyl-ACP synthases II and III (FabF and FabH, respectively), unlike platensimycin which only targets FabF. The IC50 values for platencin against FabF and FabH are 1.95 and 3.91 µg/ml, respectively. It does not exhibit cross-resistance to antibiotic resistant bacterial strains, including methicillin-resistant S. aureus, vancomycin-intermediate S. aureus, and vancomycin-resistant Enterococci. For these reasons, platencin has potential applications in fighting antibiotic resistant bacteria.Formal Name: 3-[[3-[(2S,8S)-1,3,4,7,8,8aR-hexahydro-8-methyl-3-methylene-7-oxo-2H-2,4aS-ethanon-aphthalen-8-yl]-1-oxopropyl]amino]-2,4-dihydroxy-benzoic acid.
