Anacardic acid C15:3 and cardol C15:3 sigmoidally suppressed superoxide anion (O2-) generation using xanthine oxidase. To study this suppression activity, anacardic acids, cardanols and cardols having different numbers of double bonds in alk(en)yl ch

In searching for tyrosinase inhibitors from plants using L-3,4-dihydroxyphenylalanine (L-DOPA) as a substrate, quercetin was found to be partially oxidized to the corresponding o-quinone under catalysis by mushroom tyrosinase (EC 1.14.18.1). Simultan

Cardols are resorcinolic lipids, available in many natural sources including cashew nut, pistachio, macadamia, and mango. Despite of several beneficial biological activities of cardols, cytotoxic activities of cardols are not fully understood. In pre

As a novel mushroom tyrosinase inhibitor, 4-methoxybenzonitrile (anisnitrile) was identified (IC50 = 111.1 μM) with hyperbolic inhibition manner. The calculated αKi (166.3 μM) was larger than Ki (66.5 μM) by Dixon plots, indicating that this nitr

The inhibitory activity of xanthine oxidase (XO) is a combination of uric acid formation inhibition and superoxide anion (O2-) generation suppression. The inhibition of uric acid formation by XO is useful for the screening of natural compounds that p
