| Hazard Information | Back Directory | [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) |
