Mushroom tyrosinase inhibition assay To evaluate the inhibition of the mh-Tyr by the selected flavonoids, i.e., C3G, EC, and CH, against positive control, i.e., ARB inhibitor, two different approaches, including in vitro mh-Tyr inhibition using spectrophotometer method and visual examination of enzyme inhibition by zymography method, were used to monitor the mh-Tyr activity under different concentrations of the respective compounds (Table S4)
Although often presented as a broadly beneficial polyphenol, resveratrol has also been repeatedly flagged as a potentially PAINS-susceptible molecule, owing to its redox activity, metal-chelating properties, and tendency to interfere with multiple assay formats in a non-specific manner as highlighted in the Nature commentary ( Weight of evidence: Overall evidence is Low : an add-on signal on hyperactivity without core-symptom change
