Problems of taxol development as a drug:
 Supply, Solubility, Relatively low potency, side effects
 10-deacetyl baccatin III
 Currently, all paclitaxel production uses plant cell
 fermentation (PCF) technology.

 Docetaxel is a semi-synthetic analogue of paclitaxol (Taxol)
 docetaxcel (taxotere) differ from paclitaxel at two positions in
 its structure.
-It has a hydroxyl functional group on carbon 10,
 Where paclitaxel has an acetate ester
 -a tert-butyl carbamate ester on C3- side chain
 instead of the benzamide in paclitaxel.
The C10 functional group change causes docetaxel to
be more water soluble than paclitaxel.
