Шаблон:Short description Glyceollins are a family of prenylated pterocarpans found in ineffective types of nodule in soybean in response to symbiotic infection.[1]

It possesses two chiral centers and can be asymmetrically synthesized chemically at a gram level scale.[2]

Molecules found in the family are :

Effects

They are phytoalexins[3] with an antiestrogenic activity.[4] Lygin et al. 2013[5] finds antifungal activity against Phytophthora sojae and Macrophomina phaseolina, and Kim et al. 2010 against Aspergillus sojae.[3] Kaplan et al. 1980 finds nematicidal activity against Meloidogyne incognita.[3] Parniske et al. 1991 finds an antibacterial effect.[3] Glyceollin is a vital part of soybean immunity.[3]

Metabolism

Lygin et al. 2013[5] find that daidzein is a precursor.[3] Glyceollin is a product of the phenylpropanoid pathway.[3] Glycinol is the direct precursor of glyceollins through the action of a prenyltransferase. Glyceollin synthase then transforms those prenylated precursors into glyceollins.

Inhibitors

Some pathogens produce inhibitors.[3] Ziegler & Pontzen 1982 find Phytophthora megasperma produces an extracellular invertase, a mannanglycoprotein (a glycoprotein of mannan), which prevents glyceollin accumulation not by its enzymatic action but due to an effect of its carbohydrate moiety.[3]
