d[Cha4]-AVP TFA is a potent and selective vasopressin (AVP) V1b receptor agonist with a Ki of 1.2 nM for human V1b receptor. d[Cha4]-AVP TFA shows more selective for V1b receptor than human V1a receptor, V2 receptor, and oxytocin receptors[1][2].

IC50 Target

Ki: 1.2 nM (vasopressin V1B receptor), 151 nM (vasopressin V1A receptor), 240 nM (Oxytocin receptor), 750 nM (vasopressin V2 receptor)

(In Vitro)

d[Cha4]-AVP binds to hV1b receptors and human oxytocin receptors with pKi values of 9.68 and 7.68, respectively[2].
d[Cha4]-AVP stimulates [Ca2+]i increase in hV1b-CHO cells with a pEC50 value of 10.05. d[Cha4]-AVP shows pEC50 values of 6.53 and 5.92 at hV1a and hV2 receptors, respectively, and behaved as a weak antagonist at hOT receptors (pKB=6.31)[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
