چکیده انگلیسی
The secondary metabolite production of Cordyceps annullata, an entomopathogenic fungus, was clearly enhanced by the addition of suberoyl bis-hydroxamic acid (SBHA), a histone deacetylase (HDAC) inhibitor, to the culture medium. Four new 2,3-dihydrobenzofurans, annullatins A-D (1-4), and a new aromatic polyketide, annullatin E (5) were isolated from the culture medium, and the structures, including the absolute stereochemistries, were determined by spectroscopic analysis, vibrational circular dichroism (VCD), and chemical transformations. Annullatin A (1) exhibited potent agonistic activity toward the cannabinoid receptors CB1 and CB2. Annullatin B (2) and D (4) displayed CB1 agonistic activity and CB2 inverse agonistic activity.
