CGP 36742 blocks the late inhibitory postsynaptic potential (i.p.s.p.) in CA1 pyramidal neurons[2].
CGP 36742 (1 μM) prevents kynurenate from antagonizing N-methyl-d-aspartate (NMDA) (HY-17551)-induced release of noradrenaline from rat brain slices potently[4].
CGP 36742 (1 μM) increases the somatostatin-like immunoreactivity (SRIF-LI) release from hippocampal slices exposed to NMDA[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
CGP 36742 (10 mg/kg; i.p.; once daily for 14 d) are effective in an olfactory bulbectomy (OB) model of depression in rats[1].
CGP 36742 (30-200 mg/kg; p.o.; administered in a cumulative manner at intervals of 2.5-3 h) blocks the neuronal depression induced by iontophoretically applied baclofen in anaesthetized rats[2].
CGP 36742 (1-10 mg/kg; i.v.; 25-30 min before test) dose dependently attenuates paired-pulse inhibition measured at latencies of > 100 ms[2].
CGP 36742 (50-1000 mg/kg; i.v. or p.o.; once or twice) can penetrate the blood-brain barrier in male Sprague-Dawley rats [3].

-
Animal Model:Male Albino Swiss mice (22-26 g)[1]
-
Dosage:10, 30 mg/kg
-
Administration:Intraperitoneal injection (i.p.); 30 min before test
-
Result:Significantly reduced the immobility time in the forced swim test at both doses (10 mg/kg by 32% and 30 mg/kg by 40%).
Had no effect on the spontaneous locomotor activity in mice.
-
Animal Model:Male Wistar rats (200-250 g), olfactory bulbectomy model[1]
-
Dosage:10 mg/kg
-
Administration:Intraperitoneal injection (i.p.); once daily for 14 d
-
Result:Single administration did not alter the olfactory bulbectomy (OB)-induced learning deficit, induced following bulbectomy.
Restored the learning deficit in OB rats (five trials) without affecting performance in sham-operated animals.
Reduced the OB-related increase in the number of rearings + peepings.
-
Animal Model:Male rats (weighing 280-320 g)[2]
-
Dosage:30-200 mg/kg
-
Administration:Oral gavage (p.o.); administered in a cumulative manner at intervals of 2.5-3 h.
-
Result:Antagonized baclofen-induced inhibitory effects on spontaneously firing cortical neurons in a dose-dependent manner.
-
Animal Model:Male Sprague-Dawley rats (200-325 g)[3]
-
Dosage:50, 100, 200, 500, 1000 mg/kg
-
Administration:Intravenous injection (i.v.) via tail vein of 50, 100, 200 mg/kg, oral gavage (p.o.) of 500, 1000 mg.kg; in two rats given an i.v. injection of 100 mg/kg, a second i.v. injection of 100 mg/kg was given after 6 h and samples were collected for another 6 h.
-
Result:The appearance in the rat brain frontal cortex after i.v. injection was seen in the first 30 min dialyzate collected and peaked in the 1 h dialysate.
Removed or metabolized from brain in dialyzates collected 3 h post-injection.
The presence was again seen 30 min after the second 100 mg/kg i.v. injection administered 6 h after the first injection.
Showed the appearance in the third ventricle of the rat brain after two i.v. injections of 100 mg/kg with an interval of 6 h.
Showed that the highest concentrations were seen 1.5 or 2 h after the p.o..
