Natural Polyphenols Inhibit Lysine-Specific Demethylase-1 in vitro.

Year: 2013

Type: article

Abstract: LSD1 enzymatic assays, we show that resveratrol, curcumin and quercetin displayed a potent inhibitory effect on the LSD1 activity and were more potent than the known LSD1 inhibitor trans-2-phenylcyclopropylamine (TCP). The new function of resveratrol, curcumin and quercetin is independent of their antioxidant properties, as other antioxidants had no effect on LSD1 under the similar conditions. In C2C12 fibroblasts, resveratrol and curcumin can efficiently inhibit myogenic expression and differentiation, for which LSD1 is required. Thus, our study has identified LSD1 as a novel target of bioactive natural compounds, such as resveratrol, curcumin and quercetin, and such finding suggests that LSD1 inhibition can at least partially contribute to some of the previously observed beneficial effects of these compounds.
