MTEP is a potent, non-competitive and highly selective mGluR5 antagonist, with an IC₅₀ of 5 nM and a K_i of 16 nM. MTEP shows antidepressant and anxiolytic-like effects. MTEP can be used for Parkinson's disease research. MTEP is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

In Vitro

MTEP shows highly selective for mGluR5 over mGluR1, has no effect on other mGluR subtypes, and has fewer off-target effects than MPEP (HY-14609A)^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
