Application

7,8-Dihydroxyflavone hydrate has been used as tropomyosin-receptor-kinase B (TrkB) agonist in mice and to inhibit TrkB for monitoring evoked excitatory postsynaptic currents (eEPSCs).

Actions biochimiques/physiologiques

7,8-Dihydroxyflavone (7,8-DHF) may be used to help identify and differentiate the physiological effects and cell signaling pathways mediated by TrkB activation, such as those involving, memory, vasorelaxation and hypertension. 7,8-DHF elicits protection in scopolamine induced Alzheimer-like pathologic dysfunction.
7,8-Dihydroxyflavone is a selective tyrosine kinase receptor B (TrkB) receptor agonist. It manifests all the therapeutic effects of brain-derived neurotrophic factor (BDNF)—such as protecting neurons from apoptosis, inhibiting kainic acid-induced toxicity, decreasing infarct volumes in stroke, and neuroprotecting in an animal model of Parkinson′s disease—without the poor pharmacokinetic profile of BDNF limiting its therapeutic potential.

O-methylation of flavonoids is an important modification reaction that occurs in plants. O-methylation contributes to the structural diversity of flavonoids, which have several biological and pharmacological functions. In this study, an O-methyltransferase gene (CrOMT2) was isolated from the fruit peel
