CPP-115 hydrochloride
CPP-115 hydrochloride is an orally active, selective GABA-AT inhibitor with a Ki value of 9.7 μM. CPP-115 hydrochloride blocks GABA degradation and increases GABA levels in the brain. CPP-115 hydrochloride does not bind to GABA transporters, does not displace GABA from GABAA/GABAB receptors, and does not act as an agonist/antagonist of GABAC receptors. CPP-115 hydrochloride reduces cocaine-induced dopamine release, blocks cocaine-induced conditioned place preference, and suppresses seizure activity in a rat model of infantile spasms. CPP-115 hydrochloride can be used in research related to infantile spasms and epilepsy.

Actividad biológica
CPP-115 hydrochloride potently and irreversibly inactivates GABA-AT with a kinact/KI of 52 mM·min-1, 187 times more efficiently than vigabatrin[1].
CPP-11 (6 mM) hydrochloride does not exhibit inhibitory or inactivating activity against alanine aminotransferase or aspartate aminotransferase at concentrations up to 6 mM[1].
CPP-115 (0-4.0 equiv; up to 120 h) hydrochloride time-dependently inactivates pig brain GABA-AT with a turnover number of 1.3 per active site, with greater inactivation observed at higher equivalents of the compound[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
CPP-115 (1 mg/kg) hydrochloride reduces cocaine-induced dopamine release in the nucleus accumbens (NAcc) of rats to 250% of the basal level, and its potency is over 300 times higher than that of Vigabatrin[1].
CPP-115 (0.1-1 mg/kg) hydrochloride suppresses seizure episodes in the adrenocorticotropic hormone (ACTH)-resistant multi-hit infantile spasm rat model, with a potency 100-fold higher than that of Vigabatrin and better tolerability[1].
CPP-115 (20 mg/kg per day for 45 consecutive days) hydrochloride causes only 5%-30% loss of electroretinogram in rats after 45 days of administration, showing extremely low retinal toxicity compared to the effective dose of Vigabatrin[1].
CPP-115 (0.7-7 mg/kg/day; p.o.; daily; 28 days) hydrochloride is well tolerated in healthy Beagle dogs[1].

-
Animal Model:unspecified[1]
-
Dosage:1 mg/kg
-
Administration:administered with cocaine during training
-
Result:Eliminated cocaine-induced conditioned place preference, with rats spending 7.8 minutes in the cocaine-paired chamber and 7.2 minutes in the unpaired chamber (comparable to saline/saline control levels).
Did not produce place preference alone.
-
Animal Model:unspecified[1]
-
Dosage:1 mg/kg
-
Administration:administered to modulate cocaine-induced dopamine release
-
Result:Reduced cocaine-induced nucleus accumbens dopamine level increase from 550% of basal levels to 250% of basal levels.
-
Animal Model:unspecified[1]
-
Dosage:0.5 mg/kg
-
Administration:administered with cocaine
-
Result:Prevented displacement of [11C]-raclopride in the nucleus accumbens, indicating insufficient dopamine release to displace the tracer.
-
Animal Model:unspecified[1]
-
Dosage:20 mg/kg/day
-
Administration:daily; 45 days
-
Result:Resulted in only 5-30% electroretinographic loss, a dose that is 20-40 times higher than the effective infantile spasms dose of 0.5-1 mg/kg/day.
