OLTIPRAZ Chemical Properties,Usage,Production

Description

Oltipraz (64224-21-1) upregulates the transcription factor NRF2 and prevents insulin resistance and obesity induced by high fat diet in C57BL/6J mice.1 Attenuates the progression of fibrosis in a rat model of nonalcoholic steatohepatitis.2 Oltipaz attenuates chronic hypoxia-induced cardiopulmonary alterations in mice.3 Promotes liver regeneration after partial hepatectomy.4 Off target effects: Activates constitutive androstane receptor (CAR).5

Chemical Properties

Dark Red Solid

Uses

Oltipraz is a synthetic, substituted 1,2-dithiole-3-thione previously used in humans as an antischistosomal agent. Animal studies have demonstrated that oltipraz is a potent inducer of Phase II detoxification enzymes, most notably glutathione-S-transferase (GST). Oltipraz is now known to be used for tumor prevention purposes.

Uses

schistosomicide, antineoplastic

Definition

ChEBI: A 1,2-dithiole that is 3H-1,2-dithiole-3-thione substituted at positions 4 and 5 by methyl and pyrazin-2-yl groups respectively.

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.

storage

Store at +4°C
