AZD-8418

AZD-8418 is an orally active positive allosteric modulator of metabotropic glutamate receptor 2 (mGluR2), with an EC₅₀ of 0.86 μM for rat mGlu2 receptors. AZD-8418 reduces the in vitro binding level of [³H]AZ12559322 in prefrontal cortex brain tissues of non-human primates. AZD8418 enhances the inhibitory effect of the mGlu2/3 agonist DCG-IV (HY-101335) on field excitatory postsynaptic potentials (fEPSP) in rat hippocampal brain slices. AZD-8418 reduces nicotine self-administration behavior in rats, and blocks cue-induced reinstatement of nicotine-seeking and food-seeking behaviors. The attenuating effect on nicotine self-administration behavior develops rapid tolerance, while inhibition of food self-administration behavior requires chronic administration. AZD-8418 can be used in research related to nicotine dependence and neuropsychiatric disorders.

IC₅₀ & Target

^[2]

rat mGluR2

0.86 μM (EC₅₀)

All mGluR Isoforms :

In Vitro

AZD-8418 (5 μM; 30 min) potently binds to [³H]AZ12559322 at metabotropic glutamate receptor 2 in tissue sections of cynomolgus monkey prefrontal cortex, reducing signal intensity by approximately 40-45%^[1].
AZD-8418 acts as a positive allosteric modulator of mGlu2 receptors in in vitro experiments using rat hippocampal CA1 brain slices. It potentiates DCG-IV-induced inhibition of fEPSP, with an EC₅₀ value of 0.86 μM, and exhibits no intrinsic agonist activity^[2].

Parmacokinetics

Species	Dose	Route	Note	C_max	T_max	AUC
Rat^[2]	5 mg/kg	p.o.	Day 1	690 nM	1 h	3041 nM·h
Rat^[2]	5 mg/kg	p.o.	Day 7	528 nM	1 h	2761 nM·h

In Vivo

AZD-8418 (0.37-14.92 mg/kg; p.o.; single administration) dose-dependently inhibits nicotine self-administration behavior in brown rats (Rattus norvegicus) without altering their response for maintaining food intake^[2].
AZD8418 (3.73-14.92 mg/kg/day; p.o.; for 14 consecutive days) produces a dose-dependent reduction in nicotine self-administration behavior in rats at the initial stage of administration, but tolerance develops rapidly; the highest dose also inhibits food self-administration, and this effect has a delayed onset^[2].
AZD-8418 (1.12-14.92 mg/kg; p.o.; single administration) completely blocks cue-induced relapse of nicotine-seeking behavior in rats at all tested doses, and also blocks cue-induced food-seeking behavior^[2].

Protocol

All Cell Biology

Organotypic Brain Slice Culture
Organotypic brain slice culture is an ex vivo method in which CNS tissue slices are maintained on a stable support with culture medium and oxygen access, preserving tissue architecture, multiple resident brain cell types, and network organization better than dissociated cultures. The commonly used membrane-interface method places brain or hippocampal slices on a porous membrane insert at the air-liquid interface; culture medium reaches the tissue through the membrane while the slice remains oxygenated from the humidified incubator atmosphere. Readouts depend on the experimental aim: slice survival can be monitored by propidium iodide uptake or LDH release, tissue organization by immunostaining, live structural changes by repeated imaging, and neuronal/network function by electrophysiology or multi-electrode recordings.

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.
