Pharmacology

Isoflavone is a class of polyphenolic compounds derived from the Fabaceae family with potential phytoestrogenic, cholesterol-reducing, chemotherapeutic and antioxidant activity. In isoflavones the phenyl group on the benzopyran ring is in position 3 relative to the oxygen of the ring. Most isoflavones for human consumption and that are currently studied are derived from soy beans.
