2-Chlorocinnamic acid is a photosensitive compound, it can inhibit tyrosinase activity. 2-Chlorocinnamic acid and 4-chlorocinnamic acid show potent urease inhibitory activities with the respective IC50 values of 0.66 and 1.10 uM.

Glycyrrhizin-6′′-methylester (compound 22) is a glycyrrhizin that can be isolated from licorice root. Glycyrrhizin-6′′-methylester can participate as an aglycone in the formation of methyl glucuronate, producing a sweet and licorice taste, but no bitterness. This reveals the importance of the free carboxyl group on the glycoside cone-bound glucuronic acid for natural sweetness and licorice taste.
