Desformylflustrabromine (dFBr) is a tryptamine derivative which was first isolated as an active metabolite of the marine bryozoan Flustra foliacea.^[1]

Bioactivity [edit]

dFBr has been identified as a novel positive allosteric modulator of neuronal nicotinic acetylcholine receptor with sub-type specificity for heteromeric receptor with no effect on homomeric sub-type.^[2] A recent study has been published which describes the synthesis of water-soluble salts of dFBr and its action has been confirmed as selective potentiator of α4β2 nicotinic acetylcholine receptor responses by using two-electrode voltage clamp whole cell recordings.^[3] In the year 2002 it was reported that dFBr was cytotoxic on human colon cancer cell line HCT-116. ^[4] Desformylflustrabromine has also been found to be a positive allosteric modulator for the α2β2 subtype of neuronal nicotinic acetylcholine receptor. Additionally it relieves the inhibition of both α2β2 and α4β2 Nicotinic Acetylcholine Receptors by β-Amyloid (1–42) Peptide.^[5] Thus Desformylflustrabromine can potentially be used in the treatment of Alzheimer’s disease. Many of the deconstructed analogs of dFBr are reported to have a potentiating effect on the α4β2 receptors.^[6]
