资源简介：
Three
new diterpenoids, mannolides A–C (1–3), and two new Cephalotaxus troponoids, 4 and 5, were isolated from Cephalotaxus mannii and structurally characterized
by spectroscopic data and X-ray crystallography. The discovery of
compounds 1–3 featuring a new intact
carbon skeleton, proposed as cephalotane, sheds new light on the biogenesis
of Cephalotaxus troponoids, a rare
class of antitumor C19 norditerpenoids. Antitumor tests
showed that the tropone motif is essential for the activity.
