Cumoesterol (or coumestrol), a coumestan isoflavone, has estrogenic properties (phytoestrogens are compounds structurally and functionally similar to 17-estradiol) and is an isoflavonoid phytoalexin produced by soybeans, a low molecular weight antimicrobial compound that is synthesized de novo and accumulates in plants after exposure to microorganisms (i.e.: phytoalexin induction and accumulation in soybean cotyledon tissue is observed with four species of Aspergillus: A. sojae, A. oryzae, A. niger, and A. flavus) (PMID: 10888516). Coumestrol is a naturally occurring plant coumarin that displays high affinity for the hormone-binding site of the human estrogen receptor (hER), for which it serves as a potent non-steroidal agonist. Coumestrol emits intense blue fluorescence when bound to this protein, making it ideally suited for use as a cytological stain to detect ER in fixed and intact cells. Such observations illustrate the potential for using coumestrol to investigate real-time effects of a variety of physiological stimuli on the subcellular distribution of hER in living cells (PMID: 8315272). Coumestrol is a member of the class of coumestans that is coumestan with hydroxy substituents at positions 3 and 9. It has a role as an anti-inflammatory agent, an antioxidant and a plant metabolite. It is a member of coumestans, a delta-lactone and a polyphenol. It is functionally related to a coumestan. Coumestrol is a natural product found in Campylotropis hirtella, Melilotus messanensis, and other organisms with data available. A daidzein derivative occurring naturally in forage crops which has some estrogenic activity. See also: Medicago sativa whole (part of). Isolated from Medicago subspecies, Glycine max (soybean), Pisum sativum (pea), Spinacia oleracea (spinach), Brassica oleracea (cabbage), Dolichos biflorus (papadi), Melilotus alba (white melilot), Phaseolus subspecies (inc. lima beans, pinto beans) and Vigna unguiculata (all Leguminosae).
