Description | a-Helical Corticotropin Releasing Factor (12-41) is a 30 amino acids long, α-helical analogue of corticotropin releasing factor/hormone. Corticotropin releasing factor (CRF) is a hypothalamic hormone, which stimulates the secretion of adrenocorticotrophic hormone (ACTH). a-Helical Corticotropin Releasing Factor (12-41) would suppress the stimulatory effect[1][2]. |

In Vitro | a-Helical Corticotropin Releasing Factor (0.3 nM; 5-min pulses every 40 min alternately) shows the inhibitory effect on stimulated release of immunoreactive ACTH from perifused equine anterior pituitary cells in vitro.[2]. a-Helical Corticotropin Releasing Factor (0.5-5 μM) suppresses CRH-induced ACTH secretion[2]. |
In Vivo | a-Helical Corticotropin Releasing Factor (12-41) (15-150 μg; s.c.; isolated for 30 or 60 min) suppresses the active behavioral response characteristic of guinea pig pups to brief isolation in novel surroundings[1]. Animal Model: Guinea pig pups (20-26 days old and )[1] Dosage: 15, 50, 150 μg per animal Administration: Subcutaneous injection; isolated in novel surroundings for 30 min or 60 min. Result: Resulted pups vocalized more and exhibited more locomotor activity in 20- to 26-day-old pups. Increased levels of vocalizing in isolated 4- to 6-day-old pups at 50 μg dose, though no changes were seen in locomotor activity. |
