Abstract:

Four non-paclitaxel-type taxoids taxuspine (1), taxinine (2), 1β-hydroxyl-taxinine (3), and 9,10-deacetyl taxinine (4) were isolated from Taxus cuspidata. Their anti-proliferation effects on the cell lines of HeLa, HEC-1, SHIN3, HOC-21, and HAC-2 were evaluated by using MTT assay. In addition, the structure activity relationship and the possible mechanism were discussed. The results showed that only compound 4 exhibited significant anti-proliferation activities against HeLa, HEC-1, and HAC-2 cell lines and 9,10-hydroxyl and 5-cinnamoyl group were essential for the activity. Furthermore, the apoptosis induced by 9 in Hela cell was studied by Flow Cytometry (FCM), which indicated that the anti-proliferation activity of 9,10-deacetyl taxinine was achieved by inducing HeLa cell apoptosis probably.
