ICI 174864, a putative delta opioid antagonist, reverses endotoxemic hypotension: pretreatment with dynorphin 1-13, A kappa agonist, blocks this action.
    Neuropeptides, 1984, Volume: 5, Issue:1-3

    The putative delta opioid receptor antagonist ICI 174864 (3 mg/kg, i.v.) significantly reversed endotoxic shock hypotension at a dose which lacked significant pressor actions in normotensive, non-endotoxemic rats. In contrast, dynorphin 1-13, when administered either before (0.1 or 1.0 mg/kg, i.v.) or following (1.0 mg/kg, i.v.) injection of endotoxin, failed to alter the course of ensuing circulatory shock. Additionally, pretreatment with dynorphin 1-13 prevented the subsequent reversal of endotoxemic hypotension by ICI 174864. It is concluded that: 1) delta opioid receptors mediate the endogenous opioid component of endotoxic shock hypotension; and 2) functional interactions occur between ligands for mu, delta, and kappa opioid receptor subtypes, which may predict potential interactions with a common macromolecular opioid receptor complex.
