General description

Oltipraz, a dithiol derivative, is a member of dithiolethiones class of organosulfur compounds. It has anti-tumor, antioxidative, anti- inflammatory and radioprotective properties. It provides protection from numerous carcinogens. Oltipraz functions as a schistosomicide.

Biochem/physiol Actions

Oltipraz is an activator of Nrf2. Nrf2 (NF-E2-related factor 2) is a transcription factor that binds to antioxidant response elements (AREs) and activates these genes. Oltipraz activates Nrf2 and subsequently elevates expression of the detoxification genes encoding anti-oxidant and multidrug resistance-associated proteins to mediate its chemopreventive efficacy.
