MPEP is a selective mGlu5 receptor antagonist with IC50 of 36 nM, exhibits no appreciable activity at mGlu1b/2/3/4a/7b/8a/6 receptors.MPEP是mGlu5受体非竞争性拮抗剂,IC50为36 nM,还是mGlu4受体的正向变构调节剂。
MPEP hydrochloride is a potent and selective antagonist of the mGluR5 receptor (metabotropic glutamate receptor subtype 5). MPEP hydrochloride positively modulates the hmGluR4 in a recombinant expression system, and the effect of MPEP hydrochloride is fully dependent on the activation of the orthosteric agonist L-AP4. MPEP hydrochloride reduces DHPG-induced excitations but not the excitations induced by AMPA. MPEP hydrochloride is an activator of mGluR-4.
~30 mg/kg测试前一小时腹腔注射或口服
动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
