Key words

cancer prodrugs - radiotherapy - X-ray irradiation

Significance

Activating an anticancer prodrug with clinical doses of ionizing radiation could enable localized release of a drug at the tumor site and potentially eliminate the global systemic toxicity of conventional chemo-radiotherapy. In a tumor-bearing mice model, the combination of caged prodrug and X-ray treatment not only inhibited tumor growth but also reduced doxorubicin-induced heart toxicity.

Comment

The caged doxorubicin prodrug was synthesized in two steps, by following a reported procedure (Bioconjugate Chem. 2018, 29, 324). Decaging of doxorubicin was achieved using X-ray irradiation (from 0 to 60 Gy) through radical reduction of the tetrafluorophenyl azide followed by 1,6-self-immolation linker cleavage.
