Carbetocin Acetate

Tetracosactide is a synthetic peptide, which corresponds to the first 24 amino acids of the naturally occurring hormone ACTH (adrenocorticotropic hormone). It stimulates the adrenal cortex to produce corticosteroids, mineralocorticoids, and, to a lesser extent, androgens.

Chemical Structure
ExplanationCarbetocin (trade name Duratocin) is an eight amino acid long analogue of oxytocin (a nonapeptide) with improved in vivo stability over oxytocin. Carbetocin primarily agonizes peripherally expressed oxytocin receptors.

SequenceThree Letter Code: Butyryl-Tyr(Me)-Ile-Gln-Asn-Cys-Pro-Leu-Gly-NH2(Disulfide bond)
ApplicationCarbetocin is a drug used to control postpartum hemorrhage, bleeding after giving birth, since it causes contraction of the uterus.
ActivityAgonist
Biological ActivityCarbetocin acetate, an oxytocin (OT) analogue, is an oxytocin receptor agonist with a Ki of 7.1 nM. Carbetocin acetate has high affinity to chimeric N-terminus (E1) of the oxytocin receptor (Ki=1.17 μM). Carbetocin acetate has the potential for postpartum hemorrhage research. Carbetocin acetate can crosse the blood-brain barrier and produces antidepressant-like activity via activation of oxytocin receptors in the CNS.
