Carbetocin (acetate)

Carbetocin 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[1][2][3].
