SRX246 has no interaction at V1b and V2 receptors. SRX246 shows negligible binding at 64 other receptors classes, including 35 G-proteincoupled receptors. SRX246 is a potent and CNS-penetrant vasopressin 1a (V1a) receptor antagonist (Ki=0.3 nM for human V
Selective vasopressinV1Breceptor agonist (Ki values are 0.16, 64, 100 and 3800 nM for V1B, oxytocin, V2 and V1A receptors respectively). Displays weak antidiuretic, vasopressor and in vitro oxytocic activities.
Potent and selective human vasopressinV1Breceptor agonist (Ki values are 1.2, 151, 240 and 750 nM for V1B, V1A, Oxytocin and V2 receptors respectively). Stimulates ACTH and corticosterone secretion and exhibits negligible vasopressor activity in vivo.
