Abstract
Antitumor activity of Rabdosia diterpenoids and the related compounds against Ehrlich ascites carcinoma has been studied. In addition to α-methylene cyclopentanone moiety, spirolactone aldehyde grouping functions as an active site in these compounds. Significant increase in activity can be attributed to synergism of two active sites in the molecule.
