Glucuronides in Anti-Cancer Therapy

Abstract

Glucuronide prodrugs have shown promising efficacy in anti-cancer therapy due to their increased specificity and reduced systemic toxicity. The prodrugs can be used in prodrug monotherapy (PMT), which is based on elevated tumor β-glucuronidase activity. β-Glucuronidase activates the low-toxic prodrugs into highly cytotoxic agents specifically in the tumor site. The specificity of the prodrugs can be further improved by combined use with monoclonal antibodies against tumor-specific antigens, namely antibody-directed enzyme prodrug therapy (ADEPT), and the potency of the prodrugs can be greatly enhanced with the incorporation of an appropriate radionuclide in the combined chemo- and radio-therapy of cancer (CCRTC) strategy. The prodrugs can also be utilized to modify liposomes for efficient delivery of anti-cancer drugs.
