Metabolite Identification
Common NameHarziandione
DescriptionHarziandione is a harziane diterpenoid, a class of chemical compounds characterized by their complex carbon skeletons derived from terpenes. This metabolite was first isolated from the fungus Trichoderma harzianum in 1992, marking the beginning of the discovery of various harziane diterpenoids predominantly from the Trichoderma genus (PMID:41025337 ). Subsequent studies have identified harziandione among other compounds, including new harziane diterpenes and cyclonerane sesquiterpenes, isolated from Trichoderma hamatum (PMID:39590674 ). Additionally, harziandione has been associated with other secondary metabolites, including novel compounds isolated from specific growth media (PMID:30759407 ). It has also been identified in the culture broth of Trichoderma erinaceum, which is linked to marine organisms such as the sea star Acanthaster planci (PMID:23472462 ). The structural characterization of harziandione has been supported through techniques such as optical rotation and (13)C NMR data comparison, which have also contributed to the revision of related compounds (PMID:22823323 ). Overall, harziandione exemplifies the diverse chemistry of natural products derived from fungi and highlights their potential biological significance.
