Dizocilpine maleate (Synonyms: 地卓亞平馬來酸鹽; MK-801 maleate)
Dizocilpine maleate (MK-801 maleate) 是一種有效，選擇性，非競爭性的 NMDA 受體拮抗劑，Kd 值為 37.2 nM。
生物活性
Dizocilpine maleate (MK-801 maleate) is a potent, selective and non-competitive NMDA receptor antagonist with Kd of 37.2 nM in rat brain membranes.
IC50 & Target
Ki: 37.2 nM (NMDA receptor, in rat brain membrane)[1]
體外研究(In Vitro)
[3H]Dizocilpine maleate binds with NMDA receptor with a Kd of 37.2±2.7 nM in rat cerebral cortical membranes[1].
Dizocilpine maleate causes a progressive, long-lasting blockade of current induced by N-Me-D-Asp[3].
Dizocilpine maleate progressively suppresses of current induced by NMDA. Mg2+ (10 mM) prevents Dizocilpine from blocking the N-Me-D-Asp-induced current, even when Dizocilpine (MK-801) is applied for a long time in the presence of NMDA. Dizocilpine blocks NMDA-activated single-channel activity in outside-out patches[3].
Dizocilpine maleate (< 500 μM) inhibits activation of microglia induced by LPS with increased Cox-2 protein expression in BV-2 cells. Dizocilpine (MK-801; <500 μM) reduces microglial TNF-α output with an EC50 of 400 μM in BV-2 cells[4].
體內(nèi)研究(In Vivo)
Dizocilpine maleate (MK 801 maleate) (1 mg/kg) treatment before each METH injection reduces the extent of DA depletion by 55% in striatal of mice. Dizocilpine (MK 801) (1 mg/kg) also attenuates the effects of METH on microglial activation in striatal of mice[4].
Dizocilpine maleate (0.05, 0.2 mg/kg, i.p.) attenuates subsequent cocaine-primed reinstatement without disruption in rats. Dizocilpine maleate (0.2 mg/kg, i.p.) prior to two reactivation sessions in the home cage shows no suppression on subsequent cocaine-primed reinstatement[5].
Dizocilpine maleate (0.03, 0.1, 0.3 and 1 mg/kg, i.p.) significantly increases the ambulation of mice at 0.3 and 1 mg/kg, but not at 0.03 and 0.1 mg/kg[6].
