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.
Glutamate is the most abundant excitatory neurotransmitter in the central nervous system and it modulates 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.
A-841720 (#A-440) is a highly pure, synthetic, and biologically active compound.
