α-Helical CRF (12-41) CAS NO.158535-55-8
<p>α-Helical CRF (12-41) is a synthetic 30-amino acid peptide analog of corticotropin-releasing factor (CRF), engineered with a stabilized α-helical secondary structure to function as a potent and selective antagonist of CRF receptors (CRFR1 and CRFR2). It competitively blocks the binding of endogenous CRF, effectively inhibiting the activation of the hypothalamic-pituitary-adrenal (HPA) axis. This makes it an essen…

1.MECHANISM OF ACTION
The peptide exerts its effects by binding to CRF receptors with high affinity without triggering intracellular signaling, thereby acting as a competitive antagonist. By occupying the receptor binding site, it prevents endogenous CRF from initiating the cAMP/PKA transduction cascade, which normally leads to ACTH and glucocorticoid release. This specific blockade allows researchers to dissect the role of CRF in stress responses and behavioral models without the confounding effects of receptor activation.
2.PRODUCT INDICATIONS
α-Helical CRF (12-41) is indicated for experimental research into stress-related pathologies, including anxiety, depression, and addiction. It is widely used in receptor binding assays, HPA axis modulation studies, and animal models of chronic stress to evaluate the therapeutic potential of CRF pathway inhibition. Researchers also utilize it to validate the efficacy of novel small-molecule CRF antagonists in drug discovery pipelines.
3.CLINICAL EFFICACY OF PRODUCT
In preclinical studies, this antagonist has demonstrated significant efficacy in attenuating stress-induced ACTH secretion and reversing anxiety-like behaviors in rodent models. It effectively normalizes HPA axis hyperactivity and reduces stress-related feeding and locomotor alterations. While not for human use, its robust performance in vivo makes it a critical reference standard for proof-of-concept studies in neuropsychiatric drug development
