Common NamePyripyropene A
DescriptionPyripyropene A is a polyketide metabolite belonging to the chemical class of secondary metabolites. Its chemical structure features a complex arrangement of carbon chains and functional groups that contribute to its biological activities. Pyripyropene A has been identified as a potent inhibitor of mammalian acyl-CoA cholesterol acyltransferase, implicating it in lipid metabolism pathways. In cellular studies, Pyripyropene A has demonstrated protective effects against H(2)O(2)-induced DNA oxidative damage in L02 cells (PMID:40988567 ). Additionally, it exhibits notable anti-tumor and anti-inflammatory properties, although the precise mechanisms underlying its antioxidant effects remain to be fully elucidated (PMID:40988567 ). The biosynthesis of Pyripyropene A is regulated by the Gα protein GpaB, which influences the production of several key metabolites involved in biofilm interactions, particularly in the context of pathogenic fungi such as Aspergillus fumigatus and Pseudomonas aeruginosa (PMID:40094363 ). Furthermore, Pyripyropene A has been detected during biofilm formation in co-cultures, highlighting its ecological significance within microbial communities (PMID:35856657 ).
