ROSE BENGAL LACTONE Chemical Properties,Usage,Production

Description

Rose bengal lactone is a potent inhibitor of human metabolism that binds to the proteasome pathway and inhibits the polymerization of tubulin. It has been shown to bind with high affinity to microtubules and inhibit their assembly, which leads to cell death. Rose bengal lactone also binds with high affinity to potassium ion, which may contribute to its anti-cancer effects. This compound has also been found to be an effective inhibitor of goiters in rats by binding with aliphatic hydrocarbons such as cholesterol.

Chemical Properties

Bluish-pink powder. Soluble in water.

Uses

Biological stain; colorant for inks, cellulosics, foods, cosmetics, medicine (diagnostic aid).

Preparation

will Resorcinol and 4,5,6,7-Tetrachloroisobenzofuran-1,3-dione condensation, The resulting 4,5,6,7 – tetrachloro-fluorescein tetraiodide.

Properties and Applications

blue light red. Soluble in water for blue light yellow, no fluorescence, in concentrated sulfuric acid for brown, dilution after hot pink precipitation. Used in cosmetics coloring.
