J. Kobayashi et al., TAXUSPINE-D, A NEW TAXANE DITERPENE FROM TAXUS-CUSPIDATA WITH POTENT INHIBITORY ACTIVITY AGAINST CA2-INDUCED DEPOLYMERIZATION OF MICROTUBULES(), Experientia, 51(6), 1995, pp. 592-595
A new taxane diterpenoid, taxuspine D (1), possessing an enolacetate m
oiety, has been isolated from stems of the Japanese yew Taxus cuspidat
a Sieb. et Zucc., and the structure elucidated on the basis of spectro
scopic data. Taxuspine D (1) markedly inhibited Ca2+-induced depolymer
ization of microtubules.
