Description and Uses
2,3,5,6-Tetramethylpyrazine is an alkaloid that has been found in L. wallichii and has diverse biological activities. It reduces kainate-induced increases in production of reactive oxygen species (ROS) and cytotoxicity in primary rat hippocampal neurons when used at a concentration of 5 μM. 2,3,5,6-Tetramethylpyrazine (0.1 mM) induces vasodilation in precontracted isolated and endothelium-denuded rat tail artery strips and reduces blood pressure in anesthetized rats. It decreases infarct volume, caspase-3 activation, and hypoxia-inducible factor-1α (HIF-1α) levels in a rat model of focal cerebral ischemia induced by middle cerebral artery occlusion (MCAO) when administered at a dose of 20 mg/kg.
etramethylpyrazine is an anti-inflammatory compound isolated from the fermented food natto. Tetramethylpyrazine demonstrated in vivo nootropic activity in rats.
