product name Oltipraz
Description: Oltipraz is a potent Nrf2 activator and an inducer of Phase II detoxification enzymes such as glutathione-S-transferase (GST). Oltipraz is a synthetic, substituted 1,2-dithiole-3-thione originally used in humans as an antischistosomal agent. Oltipraz has been classified as a monofunctional inducer since it advantageously elevates Phase II detoxification enzymes, while only slightly altering the expression of the Phase I “activating” enzymes.

In vitro activity: Oltipraz, as a chemoprotective agent, induces Phase II detoxification enzyme activity in a Nrf2-dependent manner. In human HT29 colon cancer cells, oltipraz inhibits the induction of HIF-1α by insulin, hypoxia or CoCl2 by significantly accelerating degradation of HIF-1α protein. Kinase Assay: Cell Assay: Oltipraz has been classified as a monofunctional inducer since it advantageously elevates Phase II detoxification enzymes, while only slightly altering the expression of the Phase I “activating” enzymes. Oltipraz effectively induced quinone reductase in Hepa 1c1c7 cells defective in the aryl hydrocarbon receptor function required by bifunctional inducers |

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, Oltipraz (200 mg/kg, p.o.) inhibits tumor growth and angiogenesis via inhibition of HIF-1α. In rats on a CDAA diet, Oltipraz attenuate the progression of nonalcoholic steatohepatitis-related fibrosis. |
Animal model | Female wild-type and nrf2-disrupted mice |
Formulation & Dosage | Suspended in 1% cremophor and 25% glycerol; 500 mg/kg; p.o. |
