The catalytic properties of peroxidase basic isoenzymes (PBIs) from Brassica napus towards trans-resveratrol (t-Res) oxidation were demonstrated by the first time by conventional UV-visible spectroscopic measurements. The enzymatic reaction rate was studied under different experimental conditions and the kinetics parameters were determined. An amperometric biosensor based on Brassica napus PBIs to determine t-Res is also proposed by the first time. The method employs a dialysis membrane covered, PBIs entrapped and ferrocene (Fc)-embedded carbon paste electrode (PBIs-Fc-CP) and is based on the fact that the decreased amount of H 2 O 2 produced by the action of PBIs is proportional to the oxidised amount of t-Res in the solution. Comparative amperometric experiments showed that, in spite of PBIs activity was much lower than commercial horseradish peroxidase (HRP) activity, t-Res was a much better substrate for PBIs biosensors than those biosensors constructed by using HRP. The PBIs-Fc-CP biosensors showed a very good stability during at least twenty days. The reproducibility and the repeatability were 4.5% and 8.3%, respectively, showing a good biosensor performance. The calibration curve was linear in the t-Res concentration (c t-Res ) range from 1 Â 10 À6 to 2.5 Â 10 À5 M, with a sensibility of (2.31 AE 0.05) Â 10 6 nA M À1. The lowest c t-Res value measured experimentally for a signal to noise ratio of 3 : 1 was 0.83 mM.

Stroke is the leading cause of death and disability worldwide, and ischemic stroke accounts for more than 85% of the stroke incidence. Tissue plasminogen activator (t-PA) is the only FDA-approved drug for ischemic stroke treatment with a narrow treatment time window of 4.5 h. Hemorrhagic transformation (HT) is a severe complication of delayed t-PA treatment in ischemic stroke. Thus, it is critically important to develop combination therapies to reduce HT and extend the therapeutic time window of t-PA. Current progress suggests that peroxynitrite (ONOO^-)/high-mobility group box 1 protein (HMGB1)/matrix metalloproteinase-9 (MMP-9) signaling cascades could be important for attenuating HT during thrombolytic treatment for acute ischemic stroke. Recently, important progress has been made in seeking for natural compounds from Chinese medicine for reducing ischemic stroke injury, with some of them targeting ONOO^-/HMGB1/MMP-9 signaling cascades. Herein, we analyze the roles and interactions of these three targets in mediating HT; subsequently, we summarize the potential compounds from Chinese herbal medicine for attenuating HT and analyze the related targets. Finally, we raise the potential issues to be addressed in further development of these compounds as combination therapy.
