title: Synthesis and NMR characterization of hydroxyurea and mesylglycol glycoconjugates as drug candidates for targeted cancer chemotherapy.
abstract: Tumor targeting of glycoconjugated antineoplastic agents is a strategy currently under investigation for cancer chemotherapy. We have synthesized the glucosides and galactosides of the clinically established drug hydroxyurea and of mesylglycol, the reactive moiety of the anticancer drug busulfan. Glycosides of hydroxyurea were obtained by carbamoylation of hydroxylamine glycosides. The glycosides of mesylglycol were synthesized by mesylation of protected glycol glycosides. All compounds were characterized by detailed 1H and 13C NMR analysis.
