New Taxane Diterpenoids from Taxus yunnanensis.[Pubmed:
24660136]
METHODS AND RESULTS:
Three hitherto unknown taxane diterpenoids, namely Baccatin VIII (1), Baccatin IX (2), and baccatin X (3), along with 10 known analogues were isolated from an ethanolic extract of the twigs and leaves of Taxus yunnanensis. The new structures were characterized based on extensive spectroscopic analysis.
CONCLUSIONS:
Compounds 1 and 2 were tested for their in vitro cytotoxicity against five human tumor cell lines, and 1 exhibited inhibitory effects on HL-60 and MCF-7, with IC50 values of 3.44 and 9.67 μM, respectively.
