Background

A 841720 is a novel non-competitive antagonist of metabotropic glutamate receptor 1 (mGluR1), with an IC50 value of 10.7 nM to 10 µM L-glutamate-induced calcium release at human mGluR1 receptors [1].

Glutamate as the major excitatory neurotransmitter in the central nervous system functions through two types of receptors, ionotropic glutamate receptors and metabotropic glutamate receptors (mGluRs). MGluRs includes group I mGluRs (mGluR1 and mGluR5 receptors), group II (mGluR2 and mGluR3 receptors) and group III (mGluR4, 6, 7, 8 receptors) [1].

In cells, agonist-induced calcium release was concentration-dependently inhibited by A 841720 in a human mGluR5 receptor FLIPR functional assay. But the IC50 value was just 343 nM. In cells expressing recombinant mGluR5 receptors, A 841720 did not block agonist-induced response. In the human mGluR1 receptor FLIPR assay, the log concentration-response curve was shifted by A 841720 at 10 nM to the right. A 841720 at increasing concentrations profoundly reduced the amplitude of L-quisqualate-evoked calcium release. A 841720 at 30 nM reduced the maximal agonist-induced response by 38%. L-quisqualate-induced response was completely abolished by A 841720 at 100 nM [1].

In a water maze test, all rats gradually learned to locate the submerged platform. Treatment with A 841720 significantly slowered rats to find the platform than vehicle control rats. Rats treated with A 841720 at both 30 and 100 µmol/kg doses not only significantly traveled longer distance to find the hidden platform, but also significantly spent longer time to reach the platform [1].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
