ICI 174864
Based on 1 Customer Validation
ICI 174864 is a selective and brain-penetrant δ-opioid receptor antagonist with Ke values of 22.0 nM to 30.6 nM at δ-opioid receptor in mouse vas deferens. ICI 174864 selectively blocks biological effects mediated by the δ-opioid receptor agonist DPDPE (HY-P1334) after central administration. ICI 174864 reverses hypotension in rats with endotoxic shock and inhibits acetic acid-induced writhing in mice. ICI 174864 can be used for the research of opioid receptor subtypes, endotoxic hypotension and analgesic pathways.

ICI 174864 selectively antagonizes delta opioid receptors in in vitro biochemical systems[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
ICI 174864 (10 μg; i.c.v.; single dose; 3-10 mg/kg; s.c.; single dose) induces dose-dependent behavioral depression and ptosis via s.c. administration, and postural abnormalities, barrel rotation, and hypothermia via i.c.v. administration in naive male Sprague Dawley rats[2].
ICI 174864 (10 μg; i.c.v.; single dose) suppresses acetic acid-induced writhing in male albino mice in a Naloxone-sensitive manner, while 5 μg (i.c.v.; single dose) selectively antagonizes the writhing-suppressant effect of delta agonist DPDPE (HY-P1334) without affecting mu agonist DAGO[2].
ICI 174864 (3μg; i.c.v.; single dose) completely blocks DADL-induced hyperphagia[3].
ICI 174864 (3 mg/kg; i.v.; single dose) significantly reverses endotoxic shock hypotension in male Sprague Dawley rats, without affecting blood pressure in normotensive rats[5].
ICI 174864 (3 mg/kg; i.v.; single dose) produces only a rapid, transient pressor response with no sustained effect in normotensive male Sprague Dawley rats[5].
