GALLEIN Chemical Properties,Usage,Production

Uses

Gallein inhibits neutrophil chemotaxis and inflammation, via the disruption of G protein βγ subunit signaling.

Definition

ChEBI: A xanthene dye that is fluoran carrying four hydroxy substituents at positions 3', 4', 5' and 6'.

Preparation

3,4,5-Trihydroxybenzoic acid or Benzene-1,2,3-triol?and Phthalic anhydride?in 190 ~ 200 ℃ reaction (namely GALLEIN), and then into sodium salt namely Alizarine Violet.

Biological Activity

Inhibitor of G protein β γ subunit-dependent signaling. Blocks PI 3-kinase and Rac1 activation in HL60 cells and chemotaxis in HL60 differentiated cells.

storage

Store at -20°C

Properties and Applications

blue light purple. Free acid soluble in hot water for the big red, soluble in hot ethanol for red light brown. In concentrated sulfuric acid to red light yellow, after dilution with fluorescence red yellow precipitation. Dye aqueous solution to join sodium hydroxide as blue.
