IC50& Target | Ki: 37.2 nM (NMDA receptor, in rat brain membrane)[1] |
体外研究 (In Vitro) | [3H]Dizocilpine maleate binds with NMDA receptor with a Kdof 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 ec50of 400 μM in BV-2 cells[4].

体内研究 (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].
