Isorhapontigenin is a tetrahydroxylated stilbenoid with a methoxy group. It is an isomer of rhapontigenin and an analog of resveratrol. [1] It is found in the Chinese herb Gnetum cleistostachyum , [2] in Gnetum parvifolium [3] and in the seeds of the palm Aiphanes aculeata . [4]

An isorhapontigenin tetramer, gnetuhainin R, can be isolated from the lianas of Gnetum hainanense . [5]

Isorhapontin, the isorhapontigenin glucoside, can be found in spruce species such as the Norway spruce ( Picea abies ), the sitka spruce ( Picea sitchensis ) and the white spruce ( Picea glauca ). [6]

Tropoflavin Chemical under investigation for medical use

Tropoflavin, also known as 7,8-dihydroxyflavone, is a naturally occurring flavone found in Godmania aesculifolia, Tridax procumbens, and primula tree leaves. It has been found to act as a potent and selective small-molecule agonist of the tropomyosin receptor kinase B (TrkB), the main signaling receptor of the neurotrophin brain-derived neurotrophic factor (BDNF). Tropoflavin is both orally bioavailable and able to penetrate the blood–brain barrier. A prodrug of tropoflavin with greatly improved potency and pharmacokinetics, R13, is under development for the treatment of Alzheimer's disease.
