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 7,8-dihydroxyflavone (7,8-DHF).^[1][2] Relative to 7,8-DHF, 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 7,8-DHF 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 7,8-DHF.^[2][3]
