Product Data:
Biological target: Oltipraz has an inhibitory effect on HIF-1α activation in a time-dependent manner, completely abrogating HIF-1α induction at ≥10 μM concentrations, the IC50 of Oltipraz for HIF-1α inhibition is 10 μM. Oltipraz is a potent Nrf2 activator.
In vitro activity: Oltipraz significantly inhibited MTB-induced death and apoptosis in human macrophages. MTB-induced reactive oxygen species production, mitochondrial depolarization and programmed necrosis were attenuated by oltipraz in macrophages. Oltipraz activated Nrf2 signaling, causing Keap1-Nrf2 disassociation, Nrf2 protein stabilization and nuclear translocation, simultaneously promoting expression of Nrf2-dependent genes (HO1, NQO1 and GST) in human macrophages. Reference: Biochem Biophys Res Commun. 2020 Oct 20;531(3):312-319. https://pubmed.ncbi.nlm.nih.gov/32800560/
In vivo activity: Oltipraz treatment abrogated insulin-induced H(2)O(2) production, thereby preventing H(2)O(2)-enhanced HIF-1alpha expression and promoting its ubiquitination and degradation. In an animal model, tumor regression by oltipraz was accompanied by decreases in microvessel density and vascular endothelial growth factor induction. Oltipraz inhibits HIF-1alpha activity and HIF-1alpha-dependent tumor growth, which may result from a decrease in HIF-1alpha stability through S6K1 inhibition in combination with an H(2)O(2)-scavenging effect.
