Our bioassay
Alomone Labs A-841720 inhibits mGluR1-mediated Ca2+ mobilization in U2OS cells.Dose-response of A-841720 (#A-440) normalized inhibition of human mGluR1-mediated, L-glutamate evoked Ca2+ mobilization. Cells were loaded with calcium-sensitive dye, incubated with a range of A-841720 concentrations, and stimulated with 5 µM L-glutamate (EC80). Changes in intracellular Ca2+ following stimulation were detected as changes in maximum relative fluorescence (RLU) using FLIPRTETRA™. IC50 was determined at 3.86 nM.

Scientific background
A-841720 is a potent, non-competitive antagonist of mGluR11,2 with an IC50 of 10 nM1. At higher concentrations it also inhibits mGluR5 receptors displaying an IC50 value of 342 nM1.
Glutamate is the most abundant excitatory neurotransmitter in the central nervous system. It modulates the activity of many types of synapses by activating in part metabotropic glutamate receptors (mGluRs). mGluRs consist of three groups: I, II, and III with a total of eight subtypes, mGluR1 to mGluR8. mGluR1 plays an important role in the central sensitization of pain and in a variety of functions with potential implications in neurological and psychiatric disorders1,2.
Target mGluR1, mGluR5
