K41498 TFA is a potent and highly selective CRF2 receptor antagonist with Ki values of 0.66 nM, 0.62 nM and 425 nM for human CRF2α, CRF2β and CRF1 receptors respectively. K41498 TFA is an analogues of antisauvagine-30 (aSvg-30), inhibits sauvagine-stimulated cAMP accumulation in hCRF2α- and hCRF2β-expressing cells. K41498 TFA can be used for hypotension study[1].
