| Bioactivity | Dizocilpine (MK-801), a potent anticonvulsant, is a selective and non-competitive NMDA receptor antagonist, with a Kd of 37.2 nM in rat brain membranes. Dizocilpine acts by binding to a site located within the NMDA associated ion channel and thus prevents Ca2+ flux[1][2]. |
| Invitro | Dizocilpine (MK-801) progressively suppresses of current induced by NMDA. Mg2+ (10 mM) prevents Dizocilpine from blocking the N-Me-D-Asp-induced current, even when Dizocilpine is applied for a long time in the presence of NMDA. Dizocilpine blocks NMDA-activated single-channel activity in outside-out patches[3]. Dizocilpine (MK-801; <500 μM) inhibits activation of microglia induced by LPS with increased Cox-2 protein expression in BV-2 cells. Dizocilpine (<500 μM) reduces microglial TNF-α output with an EC50 of 400 μM in BV-2 cells[4]. |
| In Vivo | Dizocilpine (MK 801) (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 ((+)-MK 801) (0.05, 0.2 mg/kg, i.p.) attenuates subsequent cocaine-primed reinstatement without disruption in rats. Dizocilpine (MK 801) (0.2 mg/kg, i.p.) prior to two reactivation sessions in the home cage shows no suppression on subsequent cocaine-primed reinstatement[5]. |
