New Phenol Derivatives from the Haima Cold Seep-Derived Fungus CYH-17.

Seven new phenol derivatives, subversins A-E (-), subversic acid A () and -wortmannine G (); one new natural product, 4-hydroxy-7-methoxyphthalide (); and five known compounds (-) were isolated from the fungus CYH-17 collected from the Haima cold seep. The structures and absolute configurations of these compounds were determined via NMR, MS, optical rotation, electronic circular dichroism (ECD) calculation, X-ray diffraction analysis and comparison with the literature. Compounds and were two pairs of enantiomers. All compounds were tested for their α-glucosidase and acetylcholinesterase (AChE) inhibitory activity, antioxidant activity and antibacterial activity, but no obvious activity was observed among these studied compounds.
