Packing Group III
10-Deacetylbaccatin III (10-DAB; 10-DB III) (CAS: 32981-86-5) is an intermediate for the synthesis of taxol and its derivatives. 10-Deacetylbaccatin III is a precursor product for the synthesis of Paclitaxel and Docetaxel. 10-Deacetylbaccatin III is an impurity of Paclitaxel and derivatives. 10-Deacetylbaccatin-III is an anti-tumor agent and anti-cancer intermediate.
10-Deacetylbaccatin III is a crucial intermediate for Docitaxel, two of the best anti-cancer drugs ever invented. By extracting the pre-cursor 10-DAB III in large quantites from the Taxus baccata leaf, many subsequent semiayntheses can be carried out. The esterification of 10-DAB III also causes an enhancement in the kinetics, and therefore the pharmacological profile of these important chemo-therapeutic agents.
