Terpenoids and their anti-HIV-1 activities from Excoecaria acerifolia.
Five new diterpenoids named excocarinols A-E (1-5) including three pimaranes, one cleistanthane, and one nor-beyerane, together with nine known compounds, were isolated from the EtOAc extract of the Chinese ethnodrug Gua-jing-ban (Excoecaria acerifolia Didr.). Their structures were elucidated by the analysis of spectroscopic data including 1D, 2D NMR and HR-MS. The anti-HIV-1 bioassay on the diterpenoids showed that excocarinol A (1) exhibited moderate anti-HIV-1 activity with EC50 5.58 μM and SI (Selection Index) over 112.71.
