Antisauvagine-30 TFA (aSvg-30 TFA) 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.

NBI 35965 methanesulfonate  is a CRF1 antagonist.

NBI-34041 is an effective and high-affinity CRF1 receptor antagonist that effectively reduces endocrine responses to CRF(1) receptor-mediated pharmacological and behavioral challenges.

High affinity corticotropin releasing factor receptor1 (CRF1) antagonist (Ki = 3.5 nM). Reduces stress-induced elevations of plasma ACTH. Anxiolytic and antidepressant in vivo. Orally bioavailable.

NBI-27914 is a selective and non-peptide CRFR1 (corticotropin-releasing factor receptor 1) antagonist with analgesic effects, capable of blocking CRF-induced anxiety.

Antisauvagine-30 TFA (aSvg-30 TFA), a potent peptidic antagonist specific to the CRF 2 receptor, demonstrates high selectivity and competitive interaction, with dissociation constants (Kd) of 1.4 nM for mCRFR2β and 150 nM for CRFR1, highlighting its efficacy [1] [2] [3] [4].

Urocortin II, mouse, is a selective and potent endogenous peptide agonist for the type-2 corticotropin-releasing factor (CRF2) receptor, displaying K_i values of 0.66 nM for CRFR2 and >100 nM for CRFR1, signifying its high specificity. It engages CRF2 receptors through mechanisms dependent on cAMP/PKA and Ca2+/CaMKII. Additionally, Urocortin II, mouse is localized in specific regions of the central nervous system, influencing central neurons that process visceral sensory information and regulate autonomic functions [1] [2] [3].

NBI 35965 hydrochloride is a selective CRF1 (corticotropin-releasing factor receptor 1) antagonist that is both orally active and capable of penetrating the brain. It possesses a K i value of 4 nM and a pK i of 8.5, and does not affect CRF2. This compound effectively diminishes CRF or stress-triggered ACTH (adrenocorticotropic hormone) production in vivo, demonstrating pIC 50 values of 7.1 and 6.9. Additionally, NBI 35965 hydrochloride exhibits anxiolytic properties [1] [2].
