Urolignoside is an antioxidant with free radical scavenging activity. Urolignoside potently scavenges DPPH radical, and exhibits antioxidant to β-carotene-lineoleate model[1]. 3'-Azido-3'-deoxyguanosine is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
