The research that was developed at Barretos Cancer Hospital (Brazil) in collaboration with the ICVS of the University of Minho, was a partnership with the company Amazônia Fitomedicamentos Ltda and revealed mechanisms of action involved in the cytotoxicity promoted by the euphol molecule, obtained from the Brazilian biodiversity in glioblastoma cells. One of these mechanisms was the induction of autophagic process, which also contributed, in parts, to potentiate the effect of the chemotherapy used in clinical practice, temozolomide.
