Description: 10-Deacetylbaccatin III, also known as 10-DAB or 10-DAB III, is a closely related natural organic compounds isolated from dried needles and small branches of the European yew tree (Taxus baccata).10-Deacetylbaccatin III is a precursor to the anti-cancer drug docetaxel (Taxotere). pacitaxel (taxol); cabazitaxel. 10-10-deacetylbaccatin III was found to selectively inhibit the growth of L. DONOVANI intracellular amastigotes within J774 murine macrophages in vitro at nanomolar concentrations with an IC(50) value of 70 nM.
