3-[(2-METHYL-1,3-THIAZOL-4-YL)ETHYNYL]PYRIDINE Chemical Properties,Usage,Production

Uses

MTEP Hydrochloride is a potent mGlu5 receptor antagonist, acting as a negative allosteric modulator.

Biological Activity

Cell permeable: yes', 'Primary Target
mGluR5', 'Product does not compete with ATP.', 'Reversible: no', 'Target IC50: 5 nM in Ca2+-flux assay', 'Target Ki: 16 nM for mGluR5 (metabotropic glutamate receptor subtype-5)

in vivo

MTEP (0-5 mg/kg, i.p., once) inhibits the catalepsy induced by Haloperidol (HY-14538) (0.5 mg/kg/2 ml i.p.)[2].
MTEP (0.3-3 mg/kg, intraperitoneal injection, once) induces antidepressant-like effects in male C57BL/6J mice[3].

Animal Model:Male Wistar rats (215-315 g, 5-9/group)[2]
Dosage:1, 3 and 5 mg/kg
Administration:IP, once, injected 60 min after Haloperidol (HY-14538) (0.5 mg/kg/2 ml i.p.)
Result:Inhibited the catalepsy induced by Haloperidol (HY-14538).
Animal Model:Male C57BL/6J mice (23-25 g)[3]
Dosage:0.3, 1 and 3 mg/kg
Administration:IP, 1 h before the test
Result:Significantly decreased the immobility time of mice in the tail suspension test (TST) by 24%, 41% and 48%, respectively. The efficacy of MTEP used at doses of 1 and 3 mg/kg was not significantly different from that of Imipramine (HY-B1490A) (20 mg/kg, ip), used as a positive standard.

IC 50

mGluR5: 5 nM (IC50); mGluR5: 16 nM (Ki)
