Calycosin is an O-methylated isoflavone. It can be isolated from Astragalus membranaceus Bge. var. mongholicus[1] and Trifolium pratense L. (red clover).[2]

Biosynthesis

[edit]

Isoflavone 3′-hydroxylase uses formononetin, NADPH, H+ and O2 to produce calycosin, NADP+ and H2O.

Pharmacology

[edit]

Calycosin has been shown to possess anti-cancer properties in vitro, and extracts of Astragalus membranaceus have been used to complement chemotherapy regimes in treatment of cancer in China.[3][4][5]
