4' Dimethylamino 7,8 dihydroxyflavone

4'-Dimethylamino-7,8-dihydroxyflavone (4'-DMA-7,8-DHF) is a synthetic flavone and selective small-molecule agonist of TrkB, the main receptor of brain-derived neurotrophic factor (BDNF), that was derived from structural modification of 7,8-dihydroxyflavone (7,8-DHF). Relative to 7,8-DHF, 4'-DMA-7,8-DHF possesses higher agonistic activity at TrkB, is significantly more potent than 7,8-DHF both in vitro and in vivo, and has a longer duration of action (peaking at 4 hours and "partially decaying" at 8~16 hours in rodents). The compound has been found to produce neuroprotective, neurogenic, and antidepressant-like effects in animals.
