Cytotoxic and N-Acetyltransferase Inhibitory Meroterpenoids from Ganoderma cochlear.


ABSTRACT: Seven compounds, including two pairs of new meroterpenoids, (+)- and (-)-gancochlearol C (1), (+)- and (-)-cochlearoid Q (3), and a new meroterpenoid gancochlearol D (2), together with four known meroterpenoids were isolated from the aqueous EtOH extract of the fruiting bodies of Ganoderma cochlear. Their structures were determined by spectroscopic data. The isolated compounds were evaluated for their cytotoxic activity against three human lung cancer cells (H1975, PC9, A549) and N-acetyltransferase inhibitory property. The results show that (+)-gancochlearol C could inhibit N-acetyltransferase with an IC50 value of 5.29 ?M. In addition, ganomycin F was found to show moderate activity against the H1975 human lung cancer cell line, with an IC50 value of 19.47 ?M.
