| | 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. | | Synthesis | Example 7: Synthesis of 6-hydroxy-2,5,7,8-tetramethylbenzodihydropyran-2-carboxylic acid
The 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid ester (137.3 kg) obtained in Example 6 was dissolved in methanol (137.3 kg) in a 2000 L reactor equipped with a glass liner. Subsequently, a solution containing water (411 kg) and sodium hydroxide (27 kg) was slowly added dropwise to the reaction mixture over a period of 2 hours and the hydrolysis reaction was carried out at 80 °C for 2 hours. After completion of the reaction, the hydrolysis mixture was neutralized with a solution of potassium bisulfate (91.9 kg) dissolved in water (411.9 kg) at 80 °C for 2 hours. The reaction mixture was separated by centrifugation and the obtained crystals were collected and dried using a conical dryer to finally obtain 6-hydroxy-2,5,7,8-tetramethylbenzodihydropyran-2-carboxylic acid (130.2 kg) in white powder form.
The reaction score based on 6-hydroxy-2,3,5-trimethylbenzene and the results of high performance liquid chromatography (HPLC) analysis were as follows:
