|Title:||Hydroethidine as a probe for measuring superoxide formation rates during air oxidation of myricetin and quercetin||Authors:||Quek, Y.L.
|Issue Date:||12-Oct-2011||Citation:||Quek, Y.L., Huang, D. (2011-10-12). Hydroethidine as a probe for measuring superoxide formation rates during air oxidation of myricetin and quercetin. Tetrahedron Letters 52 (41) : 5384-5387. ScholarBank@NUS Repository. https://doi.org/10.1016/j.tetlet.2011.08.044||Abstract:||In the presence of the flavonols myricetin and quercetin, oxidation of hydroethidine (HE) by superoxide yielded ethidium (E+) instead of 2-hydroxyethidium (2-OH-E+). As a known pro-oxidant, myricetin alone was also found to be able to catalyze air oxidation of HE yielding exclusively E+. The reaction is inhibited by added superoxide dismutase, suggesting that superoxide is involved in the rate limiting step of the oxidation. © 2011 Elsevier Ltd.
