Mechanism of Action

Targets/IC₅₀/Ki	Nrf2
In vitro	Oltipraz, as a chemoprotective agent, induces Phase II detoxification enzyme activity in a Nrf2-dependent manner. In human HT29 colon cancer cells, this compound inhibits the induction of HIF-1α by insulin, hypoxia or CoCl2 by significantly accelerating degradation of HIF-1α protein.
In vivo	Oltipraz (500 mg/kg, p.o.) significantly reduces multiplicity of gastric neoplasia in wild-type mice by 55%, but has no effect on tumor burden in nrf2-deficient mice. In BALB/c nude mice transplanted with HCT116 cells, this compound (200 mg/kg, p.o.) inhibits tumor growth and angiogenesis via inhibition of HIF-1α. In rats on a CDAA diet, it attenuates the progression of nonalcoholic steatohepatitis-related fibrosis.
