Marmesinin ((-)-Marmesinin), a natural coumarin, is a biosynthetic precursor of psoralen and linear furanocoumarins. Marmesinin exhibits significant neuroprotective activities against glutamate-induced toxicity[1][2]. | [Definition]
ChEBI: Marmesinin is a member of the class of psoralens that is (-)-marmesin in which the hydroxy hydrogen is replaced by a beta-D-glucosyl residue. It has a role as a plant metabolite, a P450 inhibitor and an antioxidant. It is a beta-D-glucoside, a member of psoralens and a monosaccharide derivative. It is functionally related to a nodakenetin. | [References]
