PF-06478939 TFA

PF-06478939 TFA is a potent and selective peptide agonist for oxytocin and vasopressin receptors, with EC50 values of 0.01 nM and 0.078 nM respectively. Its design prevents brain penetration, making it a valuable tool for studying the peripheral physiological and behavioral roles of these receptor systems in both in vitro and in vivo research models.
