Pterocarpano

**Pterocarpano:** estructura química. Se compone de un 1-benzofuran fracción (círculo azul de puntos) fusionado a un 2 H cromeno fracción (círculo verde de puntos). El nombre sistemático para ello es 6 H - [1] benzofuro [3,2-c] cromeno. La nueva numeración de la fracción resultante se muestra con números rojos.

Los pterocarpanos son derivados de isoflavonoides que se encuentran en la familia Fabaceae. Es un grupo de compuestos que puede ser descrito como benzo-pirano-furano-bencenos (es decir, 6H-[1]benzofuro[3,2-c] cromeno esqueleto) que se puede formar por acoplamiento del anillo B a la 4 posición.^[1]

La hydroxyisoflavona 2'-reductasa es la enzima responsable de la conversión en Cicer arietinum^[2] y glyceollin sintasa para la producción de glyceollinas, fitoalexinas en la soja.^[3]
