The emergence of multi-drug resistant bacteria is one of the major public heath crises. Platensimycin (PTM) and platencin (PTN) are potent antibacterial drug leads against many gram-postive pathogens, such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus. The past decade has witnessed the systematic study of biosynthesis, total synthesis and semisynthesis of these facinating molecules, due to their novel structures and excellent biological activities in vitro and in vivo. These studies have shed new lights on the disovery of microbial drug leads through novel high throughput strategies. Dedicated enzymes for the formation of PTM and PTN and other metabolites in their biosynthetic pathways, including new-characterized bacterial diterpenoid synthases and thiocarboxylate biosynthetic enzymes, have been revealed. The generation of many analogues of PTM and PTN though organic synthesis and precursor-directed biosynthesis has helped to establish the structure-activity relationships of PTM, PTN and their analgues. This review summarizes the progress in the disovery and development of these outstanding natural product drug leads, which supports the notion to integrate biosynthesis and organic synthesis for rapid microbial drug discovery and development.
