生物活性:
Nelonemdaz (Salfaprodil) potassium is an NR2B-selective and uncompetitive antagonist of N-methyl-D-aspartate (NMDA). Nelonemdaz potassium is also a free radical scavenger. Nelonemdaz potassium has excellent neuroprotection against NMDA- and free radical-induced cell death.
体内研究:
Nelonemdaz potassium (0.5-20 mg/kg; i.v.) reduces cerebral infarct evolving 24 h after 60-mins occlusion of the middle cerebral artery occlusion (MCAO) substantially and dose dependently.Nelonemdaz potassium (5 mg/kg; i.v.) protects white matter such as axons and myelin as well as gray matter from ischemic brain injury.Animal Model:Male Sprague-Dawley rats (260 to 300 g) (clip occlusion model)
Dosage:0.5-20 mg/kg
Administration:I.v. administration 5 mins after reperfusion
Result:Produced a large neuroprotective effect, with a maximal reduction in infarct volume of 66% at doses of 2.5 to 5 mg/kg. Not observed neuronal damage in the most vulnerable cortical area after administration of 5 mg/kg.
Animal Model:Male Sprague-Dawley rats (260 to 300 g) (intraluminal thread occlusion model)
Dosage:5 mg/kg
Administration:I.v. administration 30 mins after reperfusion
Result:Did not change physiologic variables such as arterial pH, PCO2, PO2, and hematocrit. Reduced infarct volume evolving in the cortex and the striatum substantially. Reduced white matter damage in the striatum and external capsule markedly.

Nelonemdaz potassium (10-300 μM) shows apparent neuroprotection against 300 μM N-methyl-d-aspartate (NMDA) at doses as low as 30 μM.Nelonemdaz potassium (10-500 μM) inhibits the electrophysiologic response of cultured cortical neurons to 300 μM NMDA in a concentration-dependent manner.Nelonemdaz potassium (0.1-1 μM) produces a marked reduction of Fe2+-induced neurotoxicity, even at doses of 0.1 to 0.3 μM.Nelonemdaz potassium (0.1-1 μM) blocks the degeneration of neurons and glia in cortical cell cultures.Nelonemdaz potassium (0-350 μM) effectively scavenges superoxide radicals (IC50=63.07±1.44 μM), nitric oxide (IC50=155.8±4.88 μM), and hydroxyl radicals (IC50=58.45±1.74 μM).Nelonemdaz potassium (0.78-12.5 μM) decreases the amount of antimycin A-induced ROS/RNS formation in a dose-dependent manner, with an IC50 of 2.21±0.11 μM.Nelonemdaz potassium (0.19-12.5 μM) inhibits malondialdehyde (MDA) formation with an IC50 of 2.72±0.26 μM.Nelonemdaz potassium (0-125 μM) effectively reduces iron-ascorbate-induced lipid peroxidation (IC50=24.56±0.07 μM).
