Potential use of edaravone to reduce specific side effects of chemo-, radio- and immuno-therapy of cancers. Int Immunopharmacol. 2019 Oct 26;77:105967 Authors: Bailly C Abstract The drug edaravone (EDA) is prescribed for the treatment of patients with amyotrophic lateral sclerosis or after an acute cerebral infarction. This synthetic pyrazolone derivative is a potent scavenger of oxygen free radicals and also functions as a modulator of transcription factors, repressing NFκB and activating Nrf2, to regulate oxidative stress. EDA displays complementary anti-oxidative and anti-inflammatory effects. The injectable small molecule is currently investigated for the treatment of several non-neurological diseases. The potential interest of EDA in oncology is reviewed here. EDA is a mild antiproliferative agent but has been found to enhance significantly the anticancer and antimetastatic activities of irinotecan in a colon cancer model. Anticancer derivatives of EDA have been designed but they generally display a limited antiproliferative activity. The antioxidant and anti-inflammatory activity of EDA can be best exploited to protect non-tumor cells from damages induced by chemotherapeutic drugs and radiations. Notably EDA can reduce the renal dysfunction induced by cisplatin, the neurotoxicity of cyclophosphamide and the cardiotoxicity of doxorubicin. Upon treatment with EDA, a significant improvement in neurologic symptoms has been observe...
