常见问题列表

生物活性
CNQX disodium (FG9065 disodium) 是一种有效的竞争性 AMPA /海藻酸酯受体 (AMPA/kainate receptor) 拮抗剂,IC50 分别为 0.3 μM 和 1.5 μM。CNQX disodium 是一种竞争性的非 NMDA 受体拮抗剂。CNQX disodium 会阻止大鼠恐惧增强的表达。
靶点

IC50: 0.3 μM (AMPA) and 1.5 μM (kainate receptor)

体外研究

CNQX disodium (FG9065 disodium; 2-5 μM) reversibly blocks the Schaffer collateral and mossy fibre excitatory postsynaptic potential (EPSP), while sparing the fast and slow GABA-mediated inhibition in superfusion of hippocampal slices.
CNQX disodium (1-5 μM) produces a selective and dose-dependent reduction in the amplitude of the monosynaptic component of the DR-VRR recorded from lumbar spinal segments.

体内研究

CNQX disodium (FG9065 disodium; 0.75-3 mg/kg; IP; 20 min before testing) decreased the number of cocaine responses in a dose-dependent manner during the first 15-min cocaine-free interval.
The bilateral infusion of CNQX disodium (0.5 or 1.25 μg) into the amygdala or dorsal hippocampus 10 min prior to a retention test partially blocks the expression of stepdown inhibitory avoidance in rats 24 h after training. CNQX disodium causes a complete blockade at a dose of 0.5 μg.

Animal Model: Male Wistar rats weighing 180-200 g
Dosage: 0.75, 1.5, and 3 mg/kg
Administration: IP; 20 min before testing
Result: Decreased the number of cocaine (IV; 0.25 mg/infusion) responses in a dose-dependent manner during the first 15-min cocaine-free interval.
