(a) Representative traces of recombinant INa through VGSCs expressed in tsA201 cells in the presence of 0 or 15 μg ml−1 grape extract. (b) Grape extract (15 μg ml−1, n=4, P<0.05) inhibited peak recombinant INa but did not wash out. (c) Structural formulae of resveratrol, catechin and quercetin, antioxidant polyphenols with substituted aromatic rings. Lidocaine is a VGSC blocker containing a similar aromatic group. N-acetylcysteine is an antioxidant without structural similarity to these compounds.
