Abstract
An object of the invention is to develop galactose or mannose derivatives of docetaxel, etc. having improved solubility and physiological activity, to alleviate burden imposed on patients and to provide effective therapeutic drug for tumors. The present invention provides taxoid derivatives comprising any of paclitaxel, docetaxel and 10-deacetyl-baccatin III to which galactose or mannose is linked through a spacer, and methods for producing taxoid derivatives comprising reacting paclitaxel, docetaxel or 10-deacetyl-baccatin III with tetrabenzyl acetyloxygalactoside or tetrabenzyl acetyloxymannoside, subjecting the product to debenzylation reaction, and optionally to detriethylsilylation reaction.
