VU 0364770

Additional information:
VU0364770 is a Positive allosteric modulator at mGlu4 receptors (EC50 = 290 nM in mGlu4-expressing HEK 293 cells). VU0364770 produces efficacy alone and in combination with L-DOPA or an adenosine 2A antagonist in preclinical rodent models of Parkinson’s disease.{{Aramisulpride} site|{Aramisulpride} Neuronal Signaling|{Aramisulpride} Biological Activity|{Aramisulpride} In stock|{Aramisulpride} custom synthesis|{Aramisulpride} Autophagy} |Product information|CAS Number: 61350-00-3|Molecular Weight: 232.67|Formula: C12H9ClN2O|Synonym:|VU0364770|VU 0364770|Chemical Name: N-(3-Chlorophenyl)-2-pyridinecarboxamide|Smiles: O=C(NC1=CC(Cl)=CC=C1)C1=CC=CC=N1|InChiKey: SUYUTNCKIOLMAJ-UHFFFAOYSA-N|InChi: InChI=1S/C12H9ClN2O/c13-9-4-3-5-10(8-9)15-12(16)11-6-1-2-7-14-11/h1-8H,(H,15,16)|Technical Data|Appearance: Solid Power|Purity: ≥98% (or refer to the Certificate of Analysis)|Solubility: Soluble in DMSO|Shipping Condition: Shipped under ambient temperature as non-hazardous chemical or refer to Certificate of Analysis|Storage Condition: Dry, dark and -20 oC for 1 year or refer to the Certificate of Analysis.|Shelf Life: ≥12 months if stored properly.|Stock Solution Storage: 0 – 4 oC for 1 month or refer to the Certificate of Analysis.|Drug Formulation: To be determined.|HS Tariff Code: 382200|How to use|In Vitro:|VU0364770 is a selective positive allosteric modulator of mGlu4 in recombinant systems. VU0364770 is a potent PAM of multiple signaling pathways that enhances the response of the rat and human mGlu4 receptors to the endogenous agonist glutamate. VU0364770 produces a concentration-dependent potentiation of the response to an EC20 concentration of glutamate with EC50 of 1.1±0.2 μM and increases the maximal response to glutamate from 100 to 227±17%. Because of concerns that this chemical scaffold might possess activity at MAO, full IC50 determinations is performed for VU0364770 at the MAO-A and MAO-B isoforms; these studies result in Kis of 8.5 and 0.72 μM for human MAO-A and human MAO-B, respectively. When tested at a 10 μM concentration at each mGlu receptor, VU0364770 exhibits weak PAM activity (4.3-fold left shift of the glutamate CRC) at mGlu6 and antagonist activity (3.3-fold right shift of the glutamate CRC) at mGlu5 (compare to the 16.5-fold left shift of the glutamate concentration-response for mGlu4 at 10 μM). When further evaluated in a full concentration-response curve format, VU0364770 exhibits antagonist activity at mGlu5 with a potency of 17.9±5.5 μM and PAM activity at mGlu6 with a potency of 6.8±1.7 μM (compare with the potency of VU0364770 on the rat mGlu4 receptor of 290±80 nM).|In Vivo:|VU0364770 is a selective positive allosteric modulator of mGlu4 in recombinant systems.
