Pinocembrin ((+)-Pinocoembrin) is a flavonoid found in propolis, acts as a competitive inhibitor of histidine decarboxylase, and is an effective anti-allergic agent, with antioxidant, antimicrobial and anti-inflammatory properties[1].

Name	pinocembrin
Synonyms	Galangin flavanone (2S)-5,7-Dihydroxy-2-phenyl-2,3-dihydro-4H-chromen-4-one Pinocembrin (2S)-pinocembrin Dihydrochrysin (2S)-5,7-dihydroxy-2-phenyl-2,3-dihydrochromen-4-one 5,7-Dihydroxyflavanone 4H-1-Benzopyran-4-one, 2,3-dihydro-5,7-dihydroxy-2-phenyl-, (2S)- (2S)-5,7-dihydroxy-2-phenylchroman-4-one 4H-1-Benzopyran-4-one, 2,3-dihydro-5,7-dihydroxy-2-phenyl-, (S)-(-)-

In Vitro	Pinocembrin (5, 10, 25, 50, 100 or 200 µM, 24 hours) significantly reduces cell viability of RBL-2H3 cells[1]. Pinocembrin (25 or 50 µM) suppresses iNOS, PGE-2 and COX-2 levels, increases p38-Mapk and IкB-α, and inhibits phosphorylation of IкB-α[1]. Cell Viability Assay[1] Cell Line: RBL-2H3 cells Concentration: 5, 10, 25, 50, 100 or 200 µM Incubation Time: 24 hours Result: Decreased cell viability by ∼50% at ≥ 100 µM. Showed 75% cell viability at lower concentrations.
