penicillic acid

Penicillic acid, a polyketide mycotoxin, synthesized by various species of Aspergillus and Penicillium, acts as an inhibitor of Fas ligand-induced apoptosis by impeding self-processing of caspase-8. Additionally, in vitro studies have shown that Penicillic acid displays cytotoxic properties in rat alveolar macrophages.

5,6-Dihydro-6-hydroxypenicillic acid (Compound 6) is a secondary metabolite produced by microorganisms. It can be isolated from the endophytic fungus Talaromyces sp. CPCC 400783 found in Reynoutria japonica Houtt. This compound exhibits antiviral activity against the influenza A virus, with an IC50 value of 65.45 μM.
