Norwogonin , also known as 5,7,8-trihydroxyflavone (5,7,8-THF ), is a flavone , a naturally occurring flavonoid -like chemical compound which is found in Scutellaria baicalensis (Baikal skullcap).[1] It has been found to act as an agonist of the TrkB , the main signaling receptor of brain-derived neurotrophic factor (BDNF), and appears to possess roughly the same activity in this regard to that of the closely related but more well-known tropoflavin (7,8-DHF).[2]
