Merotocin

Merotocin (INN) (developmental code name FE-202767), also known as carba-1-(4-FBzlGly⁷)dOT, is a peptidic agonist of the oxytocin receptor that was derived from oxytocin.[1][2][3] It is under development by Ferring Pharmaceuticals for the treatment of preterm mothers with lactation failure requiring lactation support, and is in phase II clinical trials for this indication.[3] Merotocin is potent (EC₅₀ < 0.1 nM) and highly selective (>1000-fold over the related vasopressin receptors).
