Oltipraz抑制HIF-1α激活, 这种作用具时间依赖性, 浓度≥10μM时完全废除HIF-1α诱导, Oltipraz抑制HIF-1α, IC50为10μM。Oltipraz 是一种有效的 Nrf2 激活剂，也是一种有效的II期解毒酶诱导剂，显著作用于谷胱甘肽-S-转移酶(GST). Oltipraz has an inhibitory effect on HIF-1α activation by insulin 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 and a potent inducer of Phase II detoxification enzymes, most notably glutathione-S-transferase (GST).
