Common NameChaetominine
DescriptionChaetominine is a bioactive alkaloid belonging to the class of natural products known as secondary metabolites. This compound has garnered attention due to its diverse biological activities, particularly its role in inducing apoptosis, cell cycle arrest, and autophagy, while inhibiting critical signaling pathways such as PI3K/Akt/mTOR, MAPK, and NF-κB (PMID:39476244 ). Chaetominine enhances chemosensitivity in cancer cells by inhibiting the PI3K/Akt/Nrf2 pathway (PMID:39476244 ). Additionally, it has been identified as a potential inhibitor of the papain-like protease (PLpro) associated with SARS-CoV-2, suggesting its viability as an antiviral agent (PMID:38916050 ). Studies have demonstrated its antiviral efficacy against SARS-CoV-2, with selectivity indices indicating moderate effectiveness (PMID:38916050 ). Furthermore, chaetominine has been isolated from various fungal sources, including marine fungi, highlighting its ecological relevance and potential for discovery of new derivatives (PMID:37933448 , PMID:35818470 ). The compound also plays a role in the secondary metabolism of the opportunistic pathogen Aspergillus fumigatus, linking it to virulence factors and conidial production (PMID:37478074 ). Overall, chaetominine represents a significant focus of research in both pharmacology and natural product chemistry.
