生物活性

描述The α/β heterodimeric hypoxia-inducible factor (HIF) complex is responsible for the activation of a large set of genes in response to hypoxia. IOX4 is a potent inhibitor of the HIF prolyl-hydroxylase 2 (PHD2) with an IC50 value of 1.6 nM. The IC50 values of IOX4 for other human 2-oxoglutarate-dependent dioxygenases, such as JMJD3, FBXL11, FIH, and FTO are 1.4, 20, 23.9, and 49μM, respectively. IOX4 inhibited the prolyl-hydroxylation of HIF1α at both NODD (HyPro402) and CODD (HyPro564) without affecting the level of PHD2 in HIFα-stabilized RCC4 cells. In von Hippel-Lindau-competent HeLa cells, IOX4 induced HIF1α at a concentration of ≥ 1μM. The EC50 values of IOX4 for HIF1α induction in MCF-7, Hep3B, and U2OS cell lines are 11.7, 11.1, and 5.6μM, respectively. Treatment of mice with 35mg/kg IOX4 for 1 h induced HIF1α and HIF2α in the liver and brain compared to the vehicle control group^[2].
作用机制IOX4 is a potent PHD2 inhibitor. It inhibits PHD2 via binding to the 2-oxoglutarate binding site^[2].
