生物活性

MPEP Hydrochloride is a potent, selective, noncompetitive, orally active and systemically active mGlu5 receptor antagonist, with an IC₅₀ of 36 nM for completely inhibiting quisqualate-stimulated phosphoinositide (PI) hydrolysis. MPEP Hydrochloride has anxiolytic-or antidepressant-like effects.

IC50 & Target[1][2]

mGluR5

36 nM (IC₅₀)

体外研究(In Vitro)

MPEP does not show agonist or antagonist activity at 100 mM on human mGlu2, -3, -4a, -7b, and -8a receptors nor at 10 μM on the human mGlu6 receptor.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究(In Vivo)

MPEP (1-30 mg/kg) induces anxiolytic-like effects in the conflict drinking test and the elevated plus-maze test in rats as well as in the four-plate test in mice.
MPEP (1-20 mg/kg) does shorten the immobility time in a tail suspension test in mice, however it is inactive in the behavioural despair test in rats.
MPEP (30 mg/kg i.p.) slightly but significantly increases (by 39%) the number of punished crossings in the four-plate test, lower doses of the compound (3 and 10 mg/kg) does not affect the number of punished crossings in that test (F (3,36)=3.240, P<0.05).
MPEP (1, 10 and 20 mg/kg) significantly (by 55% after the highest dose), (F(3,28)=15.47, P<0.001) decreases the immobility time of mice in the tail suspension test. Its efficacy is similar to that of imipramine (20 mg/kg), used as the positive standard.

Animal Model:	Male Wistar rats (200 ± 250 g).
Dosage:	IP or PO.
Administration:	0.3, 1 and 10 mg/kg, i.p. (Conflict drinking test).
Result:	At a dose of 0.3 mg/kg was not ffective, at doses of 1 and 10 mg/kg i.p. significantly (F (3,30)=11.193, P<0.001), increased the number of shocks (by 330 and 507%, respectively) accepted during the experimental session in the Vogel test.

Animal Model:	Male Wistar rats (200 ± 250 g).
Dosage:	IP or PO.
Administration:	1, 3 and 10 mg/kg, i.p. or 10 and 30 mg/kg, p.o.(Elevated plus-maze test).
Result:	Administered at a dose of 1 mg kg71 i.p. did not change the entries into and time spent in the open arms. At doses of 3 and 10 mg/kg i.p. significantly (F (3,24)=22.978, P<0.001) dose-dependently increased the time spent in the open arms (up to 45 and 74%, respectively), and the percentage of entries into the open arms (up to 48 and 68%, respectively, F(3,24)=5.678, P<.01). At doses of 3 and 10 mg/kg i.p. significantly increased (by 64%) the total number of entries and reduced (by about 25%) the total time spent (data not shown) in the arms (either type). At the dose of 30 mg/kg (po, but not 10 mg/kg) significantly (up to 64%, F (2,16)=14.249, P<0.001) increased the percentage of the time spent in the open arms and the percentage of entries into the open arms (up to 63%, F (2,16)=7.295, P<0.01). MPEP given p.o. in both doses used did not change the total number of entries nor the total time spent in the arms (either type).

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
