To clarify the relationship between the structure and inhibitory action toward β-D-galactosidase (EC 3.2.1.21) of isoflavones and isoflavone glycosides, a number of polyhydroxyisoflavones, and the α-L-rhamnosides and β-L-quinovosides of daidzein and genistein were synthesized.Among the polyhydroxyisoflavones, 2',3',4',7-tetrahydroxyisoflavone showed the strongest inhibitory activity (Ki = 26 * 10-6 M).Among the glycosides, all the L-rhamnosides were strong inhibitors, of which genistein 4',7-di-O-α-L-rhamnoside was the strongest (Ki = 4.44 * 10-6 M), while all the isoflavone β-L-quinovosides were considerably weak or possessed no inhibition.
