7,8,3'-Trihydroxyflavone
Chemical compound
Pharmaceutical compound
7,8,3′-Trihydroxyflavone (7,8,3'-THF ) is a flavone and small-molecule agonist of TrkB , the main receptor of brain-derived neurotrophic factor (BDNF), that was derived from tropoflavin (7,8-DHF).[ 1] [ 2] Relative to tropoflavin, 7,8,3'-THF is 2–3-fold more potent in vitro as a TrkB agonist.[ 1] [ 2] 7,3'-Dihydroxyflavone (7,3'-DHF) is also more potent than tropoflavin in vitro , indicating that a 3'-hydroxy group on the B-ring enhances TrkB agonistic activity.[ 1] 7,8,3'-THF has been tested in vivo and was found to produce TrkB-dependent neuroprotective effects in mice similarly to tropoflavin.[ 2] [ 3]
