      Alomone Labs A-850002 inhibits mGluR1 mediated Ca2+ mobilization in U2OS cells.
      Dose-response of normalized inhibition of human mGluR1 mediated, L-glutamate evoked Ca2+ mobilization by A-850002 (#A-390). IC50 was determined at 253 nM. hmGluR1-expressing cells were loaded with calcium-sensitive dye, incubated with a range of concentrations of A-850002, and stimulated by 15 µM L-glutamate (EC80). Changes in intracellular Ca2+ following stimulation were detected as changes in maximum relative fluorescence (RLU) using FLIPRTETRA™.

    Scientific background

    A-850002 is a synthetic, selective and potent antagonist of mGluR1 receptors. It inhibits mGluR1 receptors in rat primary cerebellar granule neurons with an IC50 value of 27 nM in calcium mobilization assays and human mGluR1 receptors expressed in 1321N1 type cells with an IC50 of 43 nM1,2.

    Metabotropic glutamate receptors (mGluRs) are G-protein coupled receptors that play an important role in synaptic plasticity and other neuro-physiological and pathological processes including a major role in central sensitization and neuropathic pain. Type 1 mGluRs are mainly found on post-synaptic neurons and are known to affect the fate of neuronal progenitor cells, neural stem cells and the formation of the hippocampus3.
