Abstract

A new cyathane diterpene, named as cyathin I (1), as well as two known cyathane diterpenes (12R)-11a,14a-epoxy-13a,14b,15-trihydroxycyath-3-ene (2) and erinacine I (3), were isolated from the liquid culture of Cyathus hookeri Berk. Their structures were elucidated on the basis of extensive spectroscopic analysis. Compounds 1-3 showed inhibition against nitric oxide production in macrophages with an IC50 value of 15.5, 52.3, and 16.8 μM, respectively.
