82-57-5

Visnagin (82-57-5) is a natural product isolated from the plant Ammi visnaga.? It displays protective effects against doxorubicin-induced cardiomyopathy via inhibition of mitochondrial malate dehydrogenase resulting in a decrease in cardiomyocyte apoptosis.1

ChEBI: Visnagin is a furanochromone that is furo[3,2-g]chromen-5-one which is substituted at positions 4 and 7 by methoxy and methyl groups, respectively. Found in the toothpick-plant, Ammi visnaga. It has a role as a phytotoxin, an EC 1.1.1.37 (malate dehydrogenase) inhibitor, a vasodilator agent, an antihypertensive agent, an anti-inflammatory agent and a plant metabolite. It is a furanochromone, an aromatic ether and a polyketide. It is functionally related to a 5H-furo[3,2-g]chromen-5-one.

Crystallise visnagin from water. It is soluble in CHCl3 but slightly soluble in EtOH. [Aneja et al. Tetrahedron 3 230 1958, Beilstein 19 III/IV 2640.]
