ODM-203 is an orally active and selective FGFR/VEGFR inhibitor with IC50 values of 6, 11, 16, 5, 9, 26 and 35 nM for FGFR3/1/2 and VEGFR3/2/1/4, respectively. ODM-203 has strong anti-tumour activity and activates immune responses in the tumour microenvironment[1].
5F-203 (NSC-703786) is a cytotoxic molecule that forms DNA adducts and cell cycle arrest. 5F-203 induces aryl hydrocarbon receptor (AhR) signaling and elevates expression of CYP1A1. 5F-203 also increases the levels of reactive oxygen species as well as activates JNK, ERK, and p38[1][2][3].
