Glyceollin

Glyceollins are a family of prenylated pterocarpan found in ineffective types of nodule in soybean in response to symbiotic infection.

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

They are phytoalexins with an antiestrogenic activity.

Molecules found in the family are :

Glycinol is the direct precursor of glyceollins through the action of a prenyltransferase. Glyceollin synthase then transforms those prenylated precursors into glyceollins.
