Significance The prognosis for patients with glioblastoma (GBM) remains poor and novel therapeutic approaches to address this unmet clinical need are urgently required. Here we show that angiotensin II (AngII), a peptide involved in salt and water balance, is produced endogenously by GBM cells and drives proliferation via the type 2 receptor of AngII (AT2R). We repurposed a peripherally restricted AT2R antagonist, originally developed for the treatment of neuropathic pain, through the generation of a compound, A3E, that has greater efficacy in vitro and optimized central nervous system penetration and efficacy in vivo with minimal toxicity. This study demonstrates that inhibition of AT2R is a promising candidate target for systemic therapy of GBM.
