yellowish to brown powder | [Uses]
Acetovanillone is an inhibitor of NADPH oxidase (an enzyme responsible for reactive oxygen species production) and is useful in the treatment of various inflammatory diseases.
| [Definition]
ChEBI: An aromatic ketone that is 1-phenylethanone substituted by a hydroxy group at position 4 and a methoxy group at position 3. | [Preparation]
Also obtained by Fries rearrangement of guaiacol acetate in the presence of zinc chloride. | [Production Methods]
Synthetically by methylation of 3,4-
Dihydroxy acetophenone. Also from Guaiacol
acetate with Zinc chloride and Acetic anhydride. Can be isolated from the extract of
the roots of Indian hemp, Apocynum cannabinum L. | [Synthesis Reference(s)]
