SIB 1757 may be used in mGluR5 metabotropic glutamate receptor-mediated cell signaling studies.
Azioni biochim/fisiol
SIB 1757 is a highly selective mGluR5 metabotropic glutamate receptor antagonist. It non-competitively inhibits glutamate-induced increase in Ca2+ at human metabotropic glutamate receptor 1 (hmGluR1).1 Inhibition of mGlu5 receptor renders protection to neurons2 against methamphetamine-induced oxidative damage.3
We have used potent and selective non-competitive antagonists of metabotropic glutamate receptor subtype 5 (mGlu5) -- 2-methyl-6-phenylethynylpyridine (MPEP), [6-methyl-2-(phenylazo)-3-pyridinol] (SIB-1757) and [(E)-2-methyl-6-(2-phenylethenyl)pyridine] (SIB-1893) - to examine whether endogenous activation of this particular metabotropic glutamate receptor subtype contributes to neuronal degeneration.

Methamphetamine (MA), a widely used drug of abuse, produces oxidative damage of nigrostriatal dopaminergic terminals. We examined the effect of subtype-selective ligands of metabotropic glutamate (mGlu) receptors on MA neurotoxicity in mice. MA (5 mg/kg, i.p.; injected three times, every

Cell lines expressing the human metabotropic glutamate receptor subtype 5a (hmGluR5a) and hmGluR1b were used as targets in an automated high-throughput screening (HTS) system that measures changes in intracellular Ca2+ ([Ca2+]i) using fluorescence detection. This functional screen was used to
