Dibenzoylmethane(DBM) is a 1,3-diketone derivative of acetylacetone that has both methyl groups replaced with phenyl groups.Although smaller in size and lacking hydroxyl and methoxy groups，DBM resembles the turmeric spice curcumin (CUR),a diferuloylmethane. Both molecules are metal-chelating agents，contain a B-diketone flanked by two aryl groups,and exhibit anti-proliferative and anticarcinogenic activity. In addition to sharing structural similarity with DBM,CUR,which is also a naturally occurring compound is found in the plant Curcuma longa and has numerous medicinal uses.
DBM and its many naturally occurring derivatives are minor constituentsof licorice. DBM has been isolated from licorice root extracts and otherspecies of Glycyrrhiza. | [Uses]
antineoplastic | [Uses]
dibenzoylmethane as a new PVC heat stabilizer, high transmittance, non-toxic and tasteless; can greatly improve the early PVC coloring, transparency, long-term stability, and processing during precipitation and "zinc burn" and so on; widely used in medical, food packaging and other non-toxic transparent PVC products. Dibenzoylmethane above can absorb 290nm ultraviolet light, while light having a stabilizing effect on PVC products can provide long-term stable performance. | [Definition]
ChEBI: A beta-diketone that is acetylacetone (acac) in which both methyl groups have been replaced by phenyl groups. It is a minor constituent of the root extract of licorice (Glycyrrhiza glabra) and exhibits antimutagenic and antica
cer effects. | [Preparation]
dibenzoylmethane is prepared by condensation of ethyl benzoate with acetophenone. | [Synthesis Reference(s)]
