CTOP TFA (0-2 nmol, ICV, once) causes withdrawal hypothermia and a loss of body weight in animals[1].
CTOP TFA (0-1.5 nmol per side, Intra-VTA injection) enhances extracellular dopamine levels in the nucleus accumbens and dose-dependently enhances locomotor activity[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Male CFLP mice (25-30 g)[1]
-
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 in a dose-dependent manner, antagonized the 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)[1]
-
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 animals.
-

Solvente y solubilidad
H2O : 50 mg/mL (Need ultrasonic)
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: PBS
Solubility: 100 mg/mL; Clear solution; Need ultrasonic
