生物活性:
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.
体内研究:
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.Animal Model:Guinea pig pups (20-26 days old and )
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.
体外研究:
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.. a-Helical Corticotropin Releasing Factor (0.5-5 μM) suppresses CRH-induced ACTH secretion.
