alpha-Helical CRF (9-41) (trifluoroacetate salt)

alpha-Helical CRF (9-41) is a synthetic peptide antagonist of corticotropin-releasing factor (CRF). It inhibits CRF-induced adrenocorticotropic hormone (ACTH) release from isolated rat anterior pituitary cells when used at concentrations ranging from 0.5 to 5 µM. In vivo, alpha-helical CRF (9-41) (0.02-0.6 µmol/kg) inhibits CRF-induced ACTH release in non-anesthetized, intact rats. It also inhibits stress-induced ACTH release in rats when administered at a dose of 0.6 µmol/kg. alpha-Helical CRF (9-41) increases social interaction time in a rat model of nicotine-induced conditioned anxiety. It also reduces binge-like ethanol consumption in mice.Synonyms: alpha-Helical Corticotropin-Releasing Factor (9-41). Molecular Formula: C166H274N46O53S2 . XCF3COOH. Formula Weight: 3826.4.
