NBI-34041

(Synonyms: SB-723620)

NBI-34041 (SB-723620) is a selective and orally active nonpeptide CRF1 receptor antagonist with an IC₅₀ of 58.9 nM and a K_i of 4.0 nM for human CRF1 receptor. NBI-34041 has no inhibitory effect on the CRF2 receptor. NBI-34041 can be used for depression and anxiety disorders research.

For research use only. We do not sell to patients.

In Vitro

NBI-34041 could inhibit the production of cAMP in a concentration-dependent manner with an IC₅₀ of approximately 60 nM. At concentrations of NBI-34041 up to 10 000 nM, NBI-34041 is unable to fully inhibit sauvagine stimulated cAMP from cells expressing the human CRF2 receptor^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

NBI-34041 (3-30 mg/kg; oral gavage; a single dose) significantly attenuates the elevation in plasma ACTH induced by CRF. NBI-34041 also demonstrates efficacy in attenuating shock-induced ACTH release in a dose-dependent manner^[1].

Animal Model:

Male Wistar or Sprague-Dawley rats (300-350 g)^[1]
Dosage:

3 mg/kg, 10 mg/kg, or 30 mg/kg
Administration:

Oral gavage; a single dose
Result:

Did not impair diurnal adrenocorticotropic hormone (ACTH) and cortisol secretion or CRF evoked ACTH and cortisol responses but attenuated the neuroendocrine response to psychosocial stress.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
