Process for mass production of GMP paclitaxel and related taxanes
-
, (2008/06/13)
A process for the purification of paclitaxel and/or cephalomannine and/or 10-DAB III and/or 9-DHAB III is described. A series of extractions, separations, and purifications provides these products in commercial quantities with high purity. The source for these natural products is from readily available renewable biomaterials, such as leaves and stems from the yew, T. canadensis.

The present invention is directed to novel taxanes useful as chemotherapeutic agents or their precursors. Processes for preparing the novel taxanes include coupling reactions, in the presence of a base, of baccatin of formula (III) or (IV) STR1 with β-lac
Method for the isolation and purification of taxol and its natural analogues
-
, (2008/06/13)
An improved method for isolating taxol and certain clinically important analogues of taxol from a crude extract of a naturally occuring Taxus species comprising treating the extract by reverse phase liquid chromatography on an adsorbent, causing the taxol and the taxol analogues to be absorbed on the adsorbent, and recovering taxol and the natural analogues of taxol from the adsorbent by elution with an elutant. The compounds thus isolated in pure form are taxol, taxol-7- xyloside, 10-deacetyltaxol, 10-deacetyltaxol-7-xyloside, cephalomannine, cephalomannine-7-xyloside, 10-deacetylcephalomannine-7-xyloside, baccatin III, 10-deacetylbaccatin III, baccatin VI, brevitaxane A, and taxiflorine.
