    Abstract:
    (-)-Trans-epsilon-viniferin (epsilon-viniferin, 5-200 microM), a dimer of resveratrol, concentration-dependently inhibited the uptake of [3H]noradrenaline and [3H]5-HT by synaptosomes from rat brain (being slightly but significantly more selective against [3H]noradrenaline) and the uptake of [3H]5-HT by human platelets. On the other hand, epsilon-viniferin (5-200 microM) concentration-dependently inhibited the enzymatic activity of commercial (human recombinant) monoamine oxidase (MAO) isoform (MAO-A and MAO-B) activity, being slightly but significantly more selective against MAO-B than against MAO-A. Taking into account that the principal groups of drugs used to treat major depression are noradrenaline/5-HT uptake or MAO inhibitors, under the assumption that epsilon-viniferin exhibits a similar behaviour in humans in vivo, our results suggest that this natural polyphenol may be of value as a structural template for the design and development of new antidepressant drugs with two important biochemical activities combined in the same chemical structure: noradrenaline/5-HT uptake and MAO inhibitory activity.
