Isolation and Characterization of trans-p-Hydroxycinnamoyl Meroterpenoids from Ganoderma sinensis

Zizhines V, W, Y, Z, (+/-)-zizhines X, and Z1-Z3, and (+/-)-ganosinensol L, thirteen new compounds including four pairs of enantiomers and a known compound (-)-ganosinensol L, were isolated from the fruiting bodies of Ganoderma sinensis. Their structures were identified by spectroscopic, computational methods, and CD (circular dichroism spectroscopy) comparisons. Zizhines V-Z and Z1-Z3 are meroterpenoids consisting of the phenolic and the terpenoidal parts. All the compounds except zizhine Z3 bear a common trans-p-hydroxycinnamoyl group. Biological evaluation shows that (-)-zizhine Z1 inhibits cell migration in the MDA-MB-231 cell lines. The present study discloses the chemical profiling of G. sinensis and paves the way for its development as functional products to benefit chronic disorders.
