Disease relevance of Chrysine


Psychiatry related information on Chrysine

  • The rats receiving chrysin (1 mg/kg) and BZF (10 mg/kg) exhibited increased libido when they were allowed to interact with nonestrous female rats [6].

High impact information on Chrysine

  • 7,8-Benzoflavone and chrysin were potent competitive inhibitors and induced spectral changes in the aromatase cytochrome P-450 indicative of substrate displacement [7].
  • Both chrysin and the benzothiophenes inhibited human recombinant CKII enzymatic activity and showed competitive kinetics with respect to ATP, analogous to the classic CKII inhibitor 5, 6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB) [8].
  • Most importantly, oral treatment of chrysin to transgenic mice that express the human UGT1 locus is unable to induce UGT1A1 expression in either the small intestine or liver [1].
  • Assessments of mitochondrial GSH levels mitochondrial membrane potential and cytochrome c release showed that the potentiation effects induced by 2',5'-DHC and chrysin involve mitochondrial dysfunction [2].
  • IKK/NF-kappaB pathway is also involved; however, kaempferol- and chrysin-mediated inhibitions are primarily executed through the attenuation of JNK activity, c-jun mRNA expression, and AP-1 activity [9].
