In a continuing study for discovering urease inhibitors based on flavonoids, nineteen reductive derivatives of flavonoids were synthesized and evaluated against Helicobacter pylori urease. Analysis of structure-activity relationship disclosed that 4-deoxy analogues are more potent than other reductive products. Out of them, 4′,7,8-trihydroxyl-2-isoflavene (13) was found to be the most active with IC50 of 0.85 μM, being over 20-fold more potent than the commercial available urease inhibitor, acetohydroxamic acid (AHA). Kinetics study revealed that 13 is a competitive inhibitor of H. pylori urease with a Ki value of 0.641 μM, which is well matched with the results of molecular docking. Biological evaluation and mechanism study of 13 suggest that it is a good candidate for discovering novel anti-gastritis and anti-gastric ulcer agent.

Pd-C/ammonium formate is a highly efficient catalyst for the selective hydrogenation of chalcones to dihydrochalcones (DHCs). The reaction proceeds under mild conditions and the Pd-C catalyst is recovered without loss of activity.

Chalcones have been found to undergo facile reduction on treatment with sodium borohydride-nickel chloride system in dioxan-methanol medium to afford dihydrochalcones.
