Prodrug activation by enzyme, a promising strategy for chemotherapy

[摘要] Strategies that promote selective activation of prodrugs by enzymes can be divided into two major classes: 1) deliver of a monoclonal antibody-enzyme immunoconjugate that can recognize a specific antigen and promote the prodrug to a citotoxic drug, with a high selectivity for the target cells, and 2) selective gene delivery encoding an enzyme that can promote the prodrug to a citotoxic drug for the target cells. In this article are discussed ADEPT (antibody-directed enzyme prodrug therapy), GDEPT (gene-directed enzyme prodrug therapy), VDEPT (virus-directed enzyme prodrug therapy), GPAT (genetic prodrug activation therapy) and PDEPT (polymer-directed enzyme prodrug therapy) approaches, their clinical trials, advantages, disadvantages and perspectives.
