目录号 : KCM12415 CAS No. : 2036081-86-2 纯度 : ≥98%
JNJ-55511118 is a negative modulator of AMPA receptors containing transmembrane AMPA receptor regulatory protein γ8 (TARP-γ8). It inhibits glutamate-induced calcium flux in HEK293F cells co-transfected with TARP-γ8 and either GluA1o, GluA1i, GluA2i, GluA3o, or GluA4o (ICs = 11.22, 12.3, 7.41, 38.02, and 15.85 nM, respectively). JNJ-55511118 is selective for GluA1o receptors containing TARP-γ8 over GluA1o receptors containing TARP-γ2, -γ3, -γ4, or -γ7 (ICs = >10 μM for all). It reduces peak glutamate-induced currents in acutely dissociated murine hippocampal neurons to 60.7% of control cells when used at a concentration of 1 μM. JNJ-55511118 (1 μM) reduces field excitatory postsynaptic potentials (fEPSPs) in the hippocampal CA1 region from wild-type, but not TARP-γ8 knockout, mice. It also inhibits corneal kindling-induced seizures in mice (ED = 3.7 mg/kg).

生物活性

JNJ-55511118 is a selective TARP γ-8 binding AMPA receptor modulator with oral bioavailability and blood-brain barrier permeability, with a Ki of 26 nM. JNJ-55511118 reduces voluntary intake of sweetened alcohol in male mice. In rodent models, JNJ-55511118 inhibits hippocampal neurotransmission, reduces specific electroencephalogram frequency bands, induces transient hyperlocomotion, impairs learning and memory abilities, and exerts anticonvulsant effects. JNJ-55511118 is applicable to research related to alcohol use disorder and seizures.

体外研究

JNJ-55511118 is a potent and selective negative modulator of AMPA receptors containing TARP-γ8, with an average pIC50 range of 7.42 to 8.33 across human, rat, mouse, monkey, and canine GluA-γ8 combinations, and is inactive against TARP-type or TARP-free AMPA receptors lacking γ8.
JNJ-55511118 (1 μM; 50-60 s) inhibits glutamate-evoked currents in heterologously expressed AMPA receptors containing TARP-γ8 by accelerating desensitization and inactivation processes.
JNJ-55511118 exhibits weak antagonistic activity against the human 5-HT2B receptor (IC50 = 6 μM).

体内研究

JNJ-55511118 (0-10 mg/kg; p.o.; single dose) can significantly reduce multiple indicators of autonomous uptake of sweet wine in male C57BL/6J mice, but does not decrease the parameters related to autonomous consumption of sweet wine in female C57BL/6J mice. However, a dose of 10 mg/kg can alter rod discrimination behavior by increasing the number of responses to ineffective rods.
JNJ-55511118 (i.v./p.o., 0-10 mg/kg, single dose) can inhibit the population spike potential in the hippocampal CA1 region of anesthetized rats. Its intravenous injection ED50 is 0.4 mg/kg, and it can dose dependently reduce cortical EEG power in multiple frequency bands in freely moving rats. Transient hyperkinesia occurs at a dose of 10 mg/kg by gavage.
JNJ-55511118 (p.o.; single dose, 0-40 mg/kg) can produce potent and almost complete seizure protection in corneal and amygdala ignited mouse models, with an oral ED50 of 3.7 mg/kg. It can partially dose dependently produce seizure protection in the 6 Hz psychomotor epilepsy model of Mus musculus, with ED50 values of 18.3 mg/kg p.o. (32 mA) and 6.5 mg/kg p.o. (44 mA), respectively, increasing the seizure threshold of mice to PTZ.

Showed no effect on alcohol-reinforced response rate, total active lever presses, number of alcohol reinforcers earned, or alcohol intake (g/kg/1h).
Reduced percentage of responses on the active lever from 92 (vehicle) to 79.9 at 10 mg/kg dose.
Increased inactive lever responding at 10 mg/kg dose.
Showed no effect on sucrose-only self-administration parameters.
Animal Model: albino CF1 (male)
Dosage: 0-40 mg/kg
Administration: p.o.; single dose
Result: Provided near-complete seizure protection at doses ≥5 mg/kg p.o.: 25/32 animals at these doses had Racine scores of 0, compared to 0/8 vehicle-treated animals.
Fitted an ED50 of 3.7 mg/kg p.o.
for seizure protection, with an EC50 of 938 ng/mL based on brain concentration.
Provided partial seizure protection: at doses ≥10 mg/kg p.o., 12/32 animals were protected in the 32 mA model, and 11/40 animals were protected in the 44 mA model.
Fitted an ED50 of 18.3 mg/kg p.o.
for the 32 mA model (76% maximum protection, EC50 4644 ng/mL plasma concentration) and 6.5 mg/kg p.o.

Significantly increased the PTZ threshold for clonus from 33.3 mg/kg to 49.5 mg/kg.
Significantly increased the PTZ threshold for twitch from 30.7 g/kg to 42.4 mg/kg.
Protected 11/12 rats from seizure, compared to 1/12 rats protected with vehicle.
Significantly reduced mean afterdischarge duration from 92 seconds (vehicle) to 35 seconds.
