CAS No.: 1124-11-4
Synonyms: Chuanxiongzine; Tetramethylpyrazine
Ligustrazine (Chuanxiongzine) is an orally active, blood-brain barrier-permeable alkaloid. It can be isolated from Ligusticum striatum DC. Ligustrazine reduces ROS, upregulates the levels of p-Akt/Akt and p-eNOS/eNOS, and decreases ALT and AST. It inhibits glutamate excitotoxicity, calcium overload, oxidative stress, ischemia-reperfusion injury and atherosclerotic plaque progression, enhances synaptic plasticity, and improves neurological function, cerebral infarct volume and brain water content. Ligustrazine possesses anti-inflammatory, antioxidant, lipid-lowering, endothelial protective and hepatoprotective activities. It can be used in studies related to ischemic stroke, cerebral ischemia-reperfusion injury and atherosclerosis .

Target:  

CRFR

Astressin 2B is a blood-brain barrier-impermeable, highly selective CRFR2 antagonist (rCRFR2, IC50=0.57 nM). Astressin 2B blocks the protective effects mediated by CRFR2, thereby exacerbating indomethacin (HY-14397)-induced hemorrhagic intestinal injury in rats. Astressin 2B reverses the protective effects of Urocortin 1 against intestinal hypermotility, bacterial invasion and upregulation of inflammatory mediators. Astressin 2B also blocks the anxiogenic effect of Urocortin 2 and attenuates stress-induced anxiety-related behaviors. In the Clostridioides difficile toxin A (C. difficile toxin A)-mediated enteritis model, Astressin 2B mimics the phenotype of CRFR2-deficient mice, significantly exacerbating intestinal epithelial damage, edema, neutrophil migration and the expression of multiple proinflammatory cytokines. Astressin 2B is an important tool molecule for investigating the intestinal protective mechanisms of CRFR2 .
