Aromatase inhibitory, radical scavenging, and antioxidant activities of depsidones and diaryl ethers from the endophytic fungus Corynespora cassiicola L36

Three compounds, corynesidones A, B, and corynether A were isolated from the fungus Corynespora cassiicola, and they exhibited potent antioxidant activity. Corynesidone A (R1 to R4 = H) was an aromatase inhibitor.
