Cat. No. 2071
Alternative Name: [D-Phe11,His12]-Sauvagine (11-40)
Biological ActivityPotent, selective and competitive corticotropin-releasing factor CRF2 receptor antagonist (Kd values are 1.4 and 153.6 nM for binding to mouse CRF2β and rat CRF1 receptors respectively). Inhibits sauvagine-stimulated cAMP accumulation in HEK-mCRF2β cells (pA2 = 8.49). Prevents stress-enhanced fear conditioning and MEK 1/2-dependent activation of ERK1/2 in mice in vivo.
Licensing InformationSold with the permission of the Max Planck Institute
