Description

Lu AF21934 is a selective and brain-penetrant mGlu4 receptor positive allosteric modulator with an EC50 of 500 nM for mGlu4 receptor[1].

IC50 & Target[1]

mGlu4 Receptor

500 nM (EC50)

In Vivo

Lu AF21934 treatment shows a dose-dependent anxiolytic-like effect in the stress-induced hyperthermia, four-plate, and marble-burying tests. The anti-hyperthermic effect of Lu AF21934 (5 mg/kg) in the SIH test is inhibited by the benzodiazepine receptor antagonist flumazenil (10 mg/kg) and is not serotonin dependent. Lu AF21934 does not produce antidepressant-like effects in the tail suspension test in mice; however, it decreases the basal locomotor activity of mice that are not habituated to activity cages[1]. Lu AF21934 (0.5-5 mg/kg sc) does not influence tremor but at doses of 0.5 and 2.5 mg/kg reverses harmaline-induced hyperactivity. Lu AF21934 at a dose of 2.5 mg/kg potentiates the inhibitory influence of harmaline on the exploratory activity and AP1 during the first 30 min of the measurement and counteracts the harmaline-increased basic activity during the period of 30-90 min[2]. Lu AF21934 (0.1-5 mg/kg) dose-dependently inhibits hyperactivity induced by MK-801 or amphetamine. It also antagonizes head twitches and increases frequency of spontaneous excitatory postsynaptic currents in brain slices, induced by DOI[3].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (7.93 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (7.93 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Animal Administration
[1]

Rats: Lu AF21934 is dispersed in 20% (2-hydropropyl)-b-cyclodextrin and are administered subcutaneously (s.c.) 60 min before the test. Lu AF21934 (2, 5, 10 and 15 mg/kg, s.c.) and diazepam (5 mg/kg, i.p.) are administered acutely 1 h before the Vogel’s conflict test. The effects of each drug in all experiments are measured in groups of 8-10 animals[1].

Mice: Lu AF21934 is dispersed in 20% (2-hydropropyl)-b-cyclodextrin and are administered subcutaneously (s.c.) 60 min before the test. Mice are gently placed into the box and allowed to explore for 15 s. Then, each time a mouse passed from one plate to another, the experimenter electrifies the whole floor thus evoking a visible flight reaction of the animal. If the animal continues running, no new shock is delivered for the following 3 s[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
