Antisauvagine-30TFA (aSvg-30TFA) is a highly selective and competitive antagonist of CRF2 receptor peptidic. It shows a Kd of 1.4 nM and 150 nM for mCRFR2β and CRFR1, respectively.
Potent, 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
