In Vitro

NMDA receptor antagonist 2 leads to excellent potency at NR2B (K_i=0.88 nM) and selectivity over hERG binding (IP=20000 nM). NMDA receptor antagonist 2 is evaluated in a functional assay measuring Ca₂₊ flux in cells expressing recombinant NR1/NR2B receptors. Selectivity over the hERG-channel is evaluated in an MK-499-binding assay^[1].
NMDA receptor antagonist 2 is highly potent in a functional assay using cells expressing NR2B (IC₅₀=1.0 nM) and remains equipotent in a binding assay using a sample of homogenized human temporal cortex (K_i=0.81 nM). In an electrophysiology assay using NR2B receptors, Compound 22 shows full blockade of ion flux with K_D=0.35 nM. Compound 22 also exhibits high levels of selectivity over NR2A (IC₅₀=200 μM), hERG binding (IP=20 μM), α-adrenergic receptors based on Prazosin binding (IC₅₀>100 μM), and CYP P450s including CYP3A4, 2C9, and 2D6^[1].

In Vivo

In pharmacokinetic studies with higher species, NMDA receptor antagonist 2 shows excellent oral bioavailability (F=83%), half-life (T_1/2=7.5 hours) and clearance (CL=3.6 mL/min/kg) in dog. And it exhibits moderate clearance (CL=12 mL/min/kg) and oral bioavailability (F=17%) in rhesus, the half-life (T_1/2) is 1.5 hours^[1].
In a rat pharmacokinetic study, NMDA receptor antagonist 2 shows oral bioavailability (F=23 %), half-life (T_1/2=0.7 hours) and clearance (CL=24 mL/min/kg), the receptor occupancy ED₅₀ with oral administration is 4.8 mg/kg in rat^[1].
In the spinal nerve ligation model of neuropathic pain in rats, surgical ligation of two lumbar nerves in the spinal column induces a state of mechanical allodynia^[1].
NMDA receptor antagonist 2 (oral administration; 3-30 mg/kg) inhibits tactile allodynia in a dose-dependent manner after oral administration at 10 and 30 mg/kg. It produces an average improvement in the maximal possible effect of 15% (3 mg/kg), 41% (10 mg/kg), and 69% (30 mg/kg) compared to vehicle treated animals^[1].
NMDA receptor antagonist 2 (oral administration; 3-30 mg/kg) is efficacious in an acute rodent model of Parkinson’s disease. Haloperidol (HY-14538) is administered at a dose previously shown to elicit an acute cataleptic response in rats, compound 22 reduces catalepsy scores in a dose-dependent manner, producing average improvements of 34% (3 mg/kg), 86% (10 mg/kg), and 92% (30 mg/kg) when it compares to vehicle group^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
