19-Hydroxy-10-deacetylbaccatin III
19-Hydroxy-10-deacetylbaccatin III (compound 13) is a taxane with potential antitumor activity. 19-Hydroxy-10-deacetylbaccatin III has weak cytotoxicity against A498 and NCI-H226 cell lines. The study found that the inhibition rates of 30 μg/mL 19-Hydroxy-10-deacetylbaccatin III on A498, NCI-H226 and PC-3 were 16.6% and 32% respectively[1].
