Quercetin 79-88 adenosine deaminase Homo sapiens 106-109 8720382-1 1996 Flavonols like quercetin, myricetin, and kaempferol inhibit the activity of the adenosine deaminase of endothelial cells (IC50 between 26 and 32 mumol/l), while flavones are inactive. Quercetin 15-24 adenosine deaminase Homo sapiens 80-99 33091574-3 2021 METHODS: Inhibition of adenosine deaminase (ADA), purine nucleoside phosphorylase (PNP) and xanthine oxidoreductase (XOR) activity by quercetin and metabolites was determined by HPLC. Quercetin 134-143 adenosine deaminase Homo sapiens 23-42 33091574-3 2021 METHODS: Inhibition of adenosine deaminase (ADA), purine nucleoside phosphorylase (PNP) and xanthine oxidoreductase (XOR) activity by quercetin and metabolites was determined by HPLC.
