Secondary Metabolites and Antifungal Activity of the Endophytic Fungus Streptomyces humidus SCB0232 from Water Chestnut

  • Published:
Chemistry of Natural Compounds Aims and scope

A new macrolide, named concanamycin H (1), together with 12 known compounds (2–13), was isolated from the endophytic Streptomyces humidus SCB0232 for the first time. Compounds 1–13 were identified by analysis of spectroscopic data. Compounds trienomycin A (2) and trienomycin E (3) exhibited moderate inhibitory activities against Fusarium verticillioides and Phytophthora infestans with IC50 values ranging from 32.64 to 72.35 μg·mL–1.
