The diterpene ferruginol has shown a strong protective effect in animal gastric ulcer models. In the present work, we report the gastroprotective effect and cytotoxicity of 16 new semisynthetic ester derivatives of ferruginol. The gastroprotective effect of these compounds was assessed with the
Two new abietane diterpenoids, ramentoxide (1) and ramentoxidone (2) and a new icetexane diterpenoid, amentonone (3) were isolated from the barks of Amentotaxus formosana. The structures of 1-3 were determined by spectroscopic methods. Known compounds brevitaxin (4), and (+)-ferruginol (5) and
Abietane diterpenoids (ADs), synthesized in the roots of different Salvia species, such as aethiopinone, 1-oxoaethiopinone, salvipisone, and ferruginol, have a variety of known biological activities. We have shown that aethiopinone has promising cytotoxic activity against several human tumor
