The Secondary Metabolites from Genus Kitasatospora : A Promising Source for Drug Discovery

Microbial secondary metabolites are well-known resource for drug discovery. Kitasatospora is one of the rare genera of Actinomycetes and important antibiotics producer that are not fully explored. Recently an explosively increasing number of reports have proved that the genus is capable of producing various bioactive secondary metabolites. Here, we comprehensively summarized secondary metabolites from Kitasatospora strains including their chemical structures, biological effects, mechanisms of actions together with the related genomic and biosynthetic analyses. The review covered more than 100 metabolites with their significant pharmacological properties. Some of these natural products which include tyropeptin has been optimized to a promising lead compound. This work provides detailed information of Kitasatospora-derived natural products and presents their potential for therapeutically relevant utilization, which would inspire the drug discovery from this genus in future.
