生物活性
(-)-MK 801 Maleate作用于大鼠腦組織膜，是一種有效的，選擇性的，非競爭性NMDA受體拮抗劑，Kd為37.2 nM。體外研究
[3H]MK-801 labels high-affinity binding sites in rat cerebral cortical membranes in a saturable manner. MK-801 produces a potent blockade of depolarizing responses to NMDA in rat cerebral cortical slices. The only compounds that are able to compete for [3H]MK-801 binding sites are substances known to block the responses of excitatory amino acids mediated by the NMDA receptor subtype. MK-801 inhibits N-methyl-D-aspartate-induced [3H]norepinephrine (NE) release and [3H]TCP binding in the hippocampus with IC50 of 20 nM and 9 nM, respectively. MK-801 causes a progressive, long-lasting blockade of current induced by NMDA. Mg2+ (10 mM) prevents MK-801 from blocking the N-Me-D-Asp-induced current, even when MK-801 is applied for a long time in the presence of NMDA. MK-801 is also effective at blocking NMDA-activated single-channel activity in outside-out patches. MK-801 (< 500 μM) prevents LPS-induced activation of microglia in a concentration-dependent manner with increased Cox-2 protein expression in BV-2 cells. MK-801 (< 500 μM) reduces microglial TNF-α output with EC50 of 400 μM in BV-2 cells.體內(nèi)研究
Treatment of mice with MK-801 (1 mg/kg) before each METH injection reduced the extent of DA depletion by 55% in striatal of mice. MK-801 (1 mg/kg) attenuates the effects of METH on microglial activation in striatal of mice. MK-801 (0.05 mg/kg or 0.2 mg/kg, i.p.) in rats just prior to reactivation of the cocaine-associated memory in the CPP context attenuates subsequent cocaine-primed reinstatement, while no disruption occurres in rats that do not receive reactivation in the CPP context. MK-801 (0.2 mg/kg, i.p.) prior to two reactivation sessions in the home cage does not suppress subsequent cocaine-primed reinstatement.生物活性

體外研究
體外神經(jīng)生理學(xué)研究使用大鼠皮質(zhì)切片制劑，證明了dizocilpine對N-Me-D-Asp去極化響應(yīng)具有有效的，選擇性的，非競爭性的拮抗作用，但是對紅藻氨酸或使君子氨酸無此作用。Phencyclidine，ketamine，SKF 10047，和dizocilpine的對映異構(gòu)體，作為N-Me-D-Asp拮抗劑的效能與它們作為[3H] dizocilpine結(jié)合抑制劑的效能密切相關(guān)。這表明，dizocilpine結(jié)合位點與N-Me-D-Asp受體相關(guān)，并解釋了dizocilpine作為抗痙攣劑的作用機制。
體內(nèi)研究
在脊髓缺血性損傷(ISCI)后，所有對照組大鼠患有嚴重的永久性神經(jīng)功能缺損，而dizocilpine治療的大鼠具有統(tǒng)計學(xué)上(P < .05)更好的神經(jīng)功能，并且恢復(fù)良好。組織病理學(xué)表明對照組大鼠的腰灰質(zhì)出現(xiàn)嚴重的神經(jīng)元壞死，而dizocilpine處理的大鼠僅表現(xiàn)出輕度損傷。這些結(jié)果表明，ISCI 之前，dizocilpine單劑量給藥提供顯著的神經(jīng)保護作用。
