Description: NBI-34041 is potent and high-affinity CRF1 receptor antagonist. NBI-34041 is safety and efficacy in attenuating elevated stress response. NBI-34041 is effective in reducing endocrine responses to pharmacological and behavioral challenge mediated by CRF(1) receptors. NBI-34041 is safe and does not impair basal regulation of the HPA system but improves resistance against psychosocial stress. NBI-34041 demonstrates that inhibition of the CRF system is a promising target for drug development against depression and anxiety disorders.
