Metabolite Identification
Common NamePrelactone B
DescriptionPrelactone B is a member of the lactone chemical class, characterized by its cyclic ester structure. This compound is produced by the endophytic bacterium Streptomyces cavourensis strain YBQ59, which also synthesizes other notable antibiotics such as bafilomycin D and nonactic acid (PMID:30533639 ). The isolation of prelactone B was achieved through the ethyl acetate extraction of the culture broth, where it was identified among several secondary metabolites (PMID:29869093 ). The chemical synthesis of prelactone B has been explored, including total syntheses and transformations leading to methyl-protected derivatives (PMID:28282511 , PMID:21707114 ). Additionally, its synthesis has been facilitated by silenes in organic chemistry (PMID:17036108 ). In terms of biological pathways, prelactone B is implicated in the biosynthesis of various secondary metabolites, which may contribute to the ecological interactions of its producing organism, although specific pathways involving prelactone B have not been extensively detailed in the literature. Overall, prelactone B represents a notable compound within the rich chemical diversity of microbial metabolites.
