CTOP

CAS No. 103429-31-8

CTOP ( —— )

产品货号. M30716 CAS No. 103429-31-8

Potent and selective μ opioid receptor antagonist (Ki values are 0.96 and >10,000 nM for μ and δ receptors respectively). Causes behavioral effects on central administration in vivo. Also increases K+ currents in rat locus ceruleus neurons in vitro via a μ receptor independent mechanism.

纯度: >98% (HPLC)

    CTOP (0-0.5 nmol, ICV, once) antagonizes the analgesic effect of morphine in a dose-dependent manner.CTOP (0-2 nmol, ICV, once) causes withdrawal hypothermia and a loss of body weight in morphine-dependent animals.CTOP (0-1.5 nmol per side, Intra-VTA injection) enhances extracellular dopamine levels in the nucleus accumbens and dose-dependently enhances locomotor activity. Animal Model:Male CFLP mice (25-30 g)Dosage:0, 0.001, 0.05, 0.075, 0.1, and 0.5 nmol (made up in artificial cerebrospinal fluid (CSF) and kept in plastic tubes at -25℃ until use)Administration:Intracerebroventricular (i.c.v.) administration, once Result:Antagonized the analgesic effect of morphine in a dose-dependent manner, antagonized.the morphine-induced hypermotility in a dose-dependent manner.Animal Model:Male CFLP mice (25-30 g, Acute dependence to morphine was induced by a single dependence-inducing (100 mg/kg) dose of morphine-HC1)Dosage:0, 0.001, 0.05, 0.2, and 2 nmol Administration:Intracerebroventricular (i.c.v.) administration, once Result:Decreased the body temperature in a dose-dependent manner, and caused withdrawal hypothermia and a loss of body weight in morphine-dependent animals.Animal Model:Long-Evans hooded rats (12, male, 350-450 g) Dosage:0, 0.015, 0.15, and 1.5 nmol per sideAdministration:Intra-VTA (ventral tegmental area) injection Result:Enhanced extracellular dopamine levels in the nucleus accumbens, dose-dependently increased activity, whereas had no effect on feeding and drinking behavior.
