Trolox Usage And Synthesis

Description

Trolox (53188-07-1) is a water soluble derivative of vitamin E. Displays antioxidant and radical scavenging activities.1 Prevents lipid peroxidation induced by CYP2E1 in Hep G2 cells.2 Trolox inhibits peroxynitrite-mediated oxidative stress and apoptosis in rat thymocytes.3

Chemical Properties

white to fainly beige crystalline powder

Uses

An antioxidant derived from water-soluble vitamin E

Uses

Trolox is a Vitamin E analog that also maintains the antioxidant capabilities which Vitamin E shows. Neuroprotective product.

Definition

ChEBI: A chromanol that is 6-hydroxychromane which is substituted by a carboxy group at position 2 and by methyl groups at positions 2, 5, 7, and 8. A cell-permeable, water-soluble analogue of vitamin E, it is used as a standard for measuring the antioxidant capa ity of complex mixtures.

Application

Trolox is a cell-permeable, water-soluble derivative of vitamin E with potent antioxidant properties. lt is commonly used as a standard or positive control in antioxidant assays.  In addition, trolox is used to assessthe role of oxidative injury in processes like neuronal cell death and aging.  It is effective as adjunctivetherapy in the treatment of certain cancers.

General Description

(±)-6-Hydroxy-2,5,7,8-tetramethylchromane-2-carboxylic acid (Trolox) exhibits radical scavenging and antioxidant activities.

Mechanism of action

Trolox can protect against oxidative stress, genotoxicity and inflammation induced by CS through ROS scavenging mechanism, and serve as a potential antioxidant prevention strategy against oxidative injury of ATII cells in CS-related lung diseases.

storage

Store at +4°C
