Abstract:
:Described here are the syntheses and preliminary biological evaluations of the first two enzymatically activated prodrugs of docetaxel (Taxotere) reported to date. These prodrugs were designed as potential candidates for selective chemotherapy in ADEPT or PMT. They are constituted of a glucuronic acid moiety, a double spacer and the cytotoxic drug, differing only by the spacer substitution. The prodrugs were stable in a buffer, and the in vitro studies showed good detoxification and hydrolysis kinetics. As docetaxel was efficiently released in both cases, these compounds are very valuable candidates for further biological evaluations.
