title: Nitrobenzylcarbamate prodrugs of cytotoxic acridines for potential use with nitroreductase gene-directed enzyme prodrug therapy.
abstract: The synthesis, solvolytic behaviour and cytotoxicity of novel 4-nitrobenzyl carbamates and carbonates derived from 3-amino-4-hydroxymethylacridine 1 are described. Compounds 2 and 6 are both substrates for Escherichia coli nitroreductase and the highly active lead structure 1 is liberated upon incubation of the two compounds in the presence of NTR and its cofactor NADH. Additionally, the cytostatic activity of 2 and 6 against human HT29 colon carcinoma cell lines is decreased 80-fold and 360-fold, respectively, indicating their suitability and potency as prodrugs for either gene-directed enzyme prodrug therapy or antibody-directed enzyme prodrug therapy.
