Abstract

The anticancer drug 5-fluorouracil-1-acetic acid was covalently attached to ß-cyclodextrin at the secondary hydroxyl side by using N, N-carbonyldiimidazole as a coupling reagent. The preliminary release behaviors of 5-fluorouracil-1-acetic acid in the gastrointestinal tract fluids of rats were studied at 37 °C, 5-Fluorouracil-1-acetic acid was almost released 52.6% from the conjugates after 24 h in the colonic fluids of rats, probably via the biodegradation by glycosidases and hydrolases.
