WebGlucuronide camptothecin is a type of prodrug produced from camptothecin and glucuronide. Glucuronide, which is also referred to as glucuronoside, is substance produced by linking glucuronic acid to another substance via a glycosidic bond. The prodrug could catalyze and produce the drug camptothecin (CPT), which was discovered in 1966. WebEster prodrugs are most often used to enhance the lipophilicity, and thus the passive membrane permeability, of water-soluble drugs by masking charged groups such as carboxylic acids and...
