About this Product
SKU:
HY-P1108A
Extra Details:
Astressin 2B TFA is a blood-brain barrier-impermeable; highly selective CRFR2 antagonist (rCRFR2; IC50=0.57 nM). Astressin 2B TFA blocks the protective effects mediated by CRFR2; thereby exacerbating indomethacin (HY-14397)-induced hemorrhagic intestinal injury in rats. Astressin 2B TFA reverses the protective effects of Urocortin 1 against intestinal hypermotility; bacterial invasion and upregulation of inflammatory mediators. Astressin 2B TFA 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 TFA mimics the phenotype of CRFR2-deficient mice; significantly exacerbating intestinal epithelial damage; edema; neutrophil migration and the expression of multiple proinflammatory cytokines. Astressin 2B TFA is an important tool molecule for investigating the intestinal protective mechanisms of CRFR2[1][2][3][4][5][6][7].
