MPEP 在人 mGlu2、-3、-4a、-7b 和 -8a 受体上的浓度为 100 mM,在人 mGlu6 受体上的浓度为 10 μM 时,既不表现出激动剂也不表现出拮抗剂活性[1]。

体内研究 (In Vivo) |
在小鼠的冲突饮酒试验、高架十字迷宫试验和四板试验中,MPEP(1-30 mg/kg)会产生抗焦虑样作用[2]。在尾部悬吊试验中,MPEP(1-20 mg/kg)确实缩短了小鼠的不动时间;然而,在行为绝望测试中,它对大鼠没有影响[2]。较低剂量的化学品(3 和 10 mg/kg)对四板试验中惩罚交叉的数量没有影响(F (3,36)=3.240,P<0.05)[2]。然而,MPEP(30 mg/kg ip)略微但显着增加了该测试中受惩罚交叉的数量(增加了 39%)。 MPEP(1、10和20mg/kg)显着缩短了尾部悬吊试验中小鼠的不动时间(F(3,28)=15.47,P<0.001),最高剂量后观察到减少了55%。其有效性与阳性标准丙咪嗪(20 mg/kg)相当[2]。

其他信息 |
2-methyl-6-(phenylethynyl)pyridine is a methylpyridine that coinsists of 2-methylp[yridine bearing an additional phenylethynyl group at position 6. Potent and highly selective non-competitive antagonist at the mGlu5 receptor subtype (IC50 = 36 nM) and a positive allosteric modulator at mGlu4 receptors. Centrally active following systemic administration in vivo. Reverses mechanical hyperalgesia in the inflamed rat hind paw. It has a role as a metabotropic glutamate receptor antagonist and an anxiolytic drug. It is a member of methylpyridines and an acetylenic compound. It is a conjugate base of a 2-methyl-6-(phenylethynyl)pyridinium(1+). It derives from a hydride of an acetylene.

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
