OT antagonist 1 (Compound 4) is a potent, selective Oxytocin antagonist with a Ki of 50 nM.

IC50 & Target

Ki: 50 nM (Oxytocin)[1]

In Vitro

Oxytocin (OT) is a nonapeptide hormone that acts on the OT receptor, a seven-transmembrane (7TM) (Gq-coupled) receptor. The OT receptor has no subtypes but is related to the vasopressin receptors V1A, V1B and V2. OT antagonists have therapeutic potential in a number of areas including pre-term labour: Benign Prostatic Hyperplasia and sexual dysfunction. As a result there is significant interest in the identification of potent, selective, orally bioavailable OT antagonists[1].
