Kobophenol A
Encyclopedia
Kobophenol A is a stilbene tetramer
. It can be isolated from Caragana chamlague and from Caragana sinica
.
It has been shown to inhibit acetylcholinesterase
.
Acid-catalyzed epimerization of kobophenol A to carasinol B
can be performed in vitro.
Tetramer
A tetramer is a protein with four subunits . There are homotetramers such as glutathione S-transferase or single-strand binding protein, dimers of hetero-dimers such as hemoglobin , and heterotetramers, where each subunit is different.-Subunit interactions in tetramers:The interactions between...

Caragana sinica
Caragana sinica is a species belonging to the genus Caragana.Caragana sinica is known to produce α-viniferin, a stilben trimer showing acetylcholinesterase inhibitory activity and two stilbene tetramers kobophenol A, and carasinol B....

Acetylcholinesterase
"Acetylcholinesterase, also known as AChE or acetylcholine acetylhydrolase, is an enzyme that degrades the neurotransmitter acetylcholine, producing choline and an acetate group. It is mainly found at neuromuscular junctions and cholinergic nervous system, where its activity serves to terminate...
