Biological Activity of YM 298198 hydrochloride

DescriptionNon-competitive antagonist with high affinity and selectivity for mGlu1 receptors (Ki = 19 nM); inactive at other mGlu receptor subtypes (mGlu2-7), ionotropic receptors and glutamate transporters (IC50 > 10 μM). Inhibits glutamate-induced IP production more potently than CPCCOEt (IC50 values are 16 nM and 6.3 μM respectively), and is orally active in vivo, demonstrating an antinociceptive effect in hyperalgesic mice. Desmethyl derivative also available.

The protective signaling of metabotropic glutamate receptor 1 Is mediated by sustained, beta-arrestin-1-dependent ERK phosphorylation.[Pubmed:20566651]

J Biol Chem. 2010 Aug 20;285(34):26041-8.

Metabotropic glutamate receptor 1 (mGlu1) is a G protein-coupled receptor that enhances the hydrolysis of membrane phosphoinositides. In addition to its role in synaptic transmission and plasticity, mGlu1 has been shown to be involved in neuroprotection and neurodegeneration. In this capacity, we have reported previously that in neuronal cells, mGlu1a exhibits the properties of a dependence receptor, inducing apoptosis in the absence of glutamate, while promoting neuronal survival in its presence (Pshenichkin, S., Dolinska, M., Klauzinska, M., Luchenko, V., Grajkowska, E., and Wroblewski, J. T. (2008) Neuropharmacology 55, 500-508). Here, using CHO cells expressing mGlu1a receptors, we show that the protective effect of glutamate does not rely on the classical mGlu1 signal transduction. Instead, mGlu1a protective signaling is mediated by a novel, G protein-independent, pathway which involves the activation of the MAPK pathway and a sustained phosphorylation of ERK, which is distinct from the G protein-mediated transient ERK phosphorylation. Moreover, the sustained phosphorylation of ERK and protective signaling through mGlu1a receptors require expression of beta-arrestin-1, suggesting a possible role for receptor internalization in this process. Our data reveal the existence of a novel, noncanonical signaling pathway associated with mGlu1a receptors, which mediates glutamate-induced protective signaling.

Radioligand binding properties and pharmacological characterization of 6-amino-N-cyclohexyl-N,3-dimethylthiazolo[3,2-a]benzimidazole-2-carboxamide (YM-298198), a high-affinity, selective, and noncompetitive antagonist of metabotropic glutamate receptor type 1.[Pubmed:15976016]

J Pharmacol Exp Ther. 2005 Oct;315(1):163-9.

Metabotropic glutamate receptor type 1 (mGluR1) is thought to play important roles in the neurotransmission and pathogenesis of several neurological disorders. Here, we describe the radioligand binding properties and pharmacological effects of a newly synthesized, high-affinity, selective, and noncompetitive mGluR1 antagonist, 6-amino-N-cyclohexyl-N,3-dimethylthiazolo[3,2-a]benzimidazole-2-carboxamide (YM-298198). YM-298198 inhibited glutamate-induced inositol phosphate production in mGluR1-NIH3T3 cells with an IC50 of 16 +/- 5.8 nM in a noncompetitive manner. Its radiolabeled form, [3H]YM-298198, bound to mGluR1-NIH3T3 cell membranes with a KD of 32 +/- 8.5 nM and a Bmax of 2297 +/- 291 fmol/mg protein. In ligand displacement experiments using rat cerebellum membrane, an existing noncompetitive mGluR1 antagonist 7-(hydroxyimino)cyclo-propa[b]chromen-1a-carboxylate ethyl ester (CPCCOEt) competitively displaced [3H]YM-298198 binding, although glutamate and other mGluR1 ligands acting on a glutamate site failed to inhibit [3H]YM-298198 binding, suggesting that YM-298198 binds to CPCCOEt (allosteric) binding sites but not to glutamate (agonist) binding sites. Specificity was demonstrated for mGluR1 over mGluR subtypes 2 to 7, ionotropic glutamate receptors, and other receptor, transporter, and ion channel targets. In in vivo experiments, orally administered YM-298198 showed a significant analgesic effect in streptozotocin-induced hyperalgesic mice at doses (30 mg/kg) that did not cause Rotarod performance impairment, indicating that it is also useful even for in vivo experiments. In conclusion, YM-298198 is a newly synthesized, high-affinity, selective, and noncompetitive antagonist of mGluR1 that will be a useful pharmacological tool due to its highly active properties in vitro and in vivo. Its radiolabeled form [3H]YM-298198 will also be a valuable tool for future investigation of the mGluR1.
