MTEP

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^[1][2][3][4]. MTEP is a click chemistry reagent, itcontains 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]. 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].
