产品描述 2-PMPA (2-(Phosphonomethyl)pentanedioic acid) is a potent and selective inhibitor of glutamate carboxypeptidase II (GCPII) (IC50=300 pM).
靶点活性 GCP II:300 pM
体外活性 2-PMPA is a potent and selective inhibitor of GCPII. GCPII is an enzyme that catabolizes the abundant neuropeptide N-acetyl-aspartyl-glutamate (NAAG) to N-acetylaspartate (NAA) and glutamate. 2-PMPA demonstrates robust efficacy in numerous animal models of neurological disease. 2-PMPA is a highly polar compound with multiple negative charges causing significant challenges for analysis in biological matrices[1]. 2-PMPA reduces ketamine-induced decrease of cell viability and increase of LDH levels in the mixed cultures but not in the neuronal cultures[2].
体内活性 Intraperitoneal administration of 100 mg/kg 2-PMPA results in maximum concentration in plasma of 275 μg/mL at 0.25 h. The half-life, area under the curve, apparent clearance, and volume of distribution are 0.64 h, 210 μg×h/mL, 7.93 mL/min/kg, and 0.44 L/kg, respectively[1]. 2-PMPA at 250 mg/kg, in an anesthetized mouse, after an initial rise, produces a rapid decline and a striking attenuation in BOLD signals in gray matter. The signature of 2-PMPA on brain T2* signals in gray matter at both 167 and 250 mg/kg includes a significant initial rise lasting several minutes[3]. 2-PMPA exhibits neuroprotective activity in an animal model of stroke and anti-allodynic activity in CCI model. Administration of 2-PMPA (50 mg/kg) produces a mean peak concentration of 2-PMPA of 29.66±8.1 μM. This concentration is about 100,000 fold more than is needed for inhibition of NAAG peptidase and suggests extremely good penetration to the brain. Administration of 50 mg/kg 2-PMPA (i.p.) produces a continuously increasing extracellular NAAG concentration, which startes directly after application[4].
细胞实验 Neuronal cultures and neuron–glia mixed cultures are treated with ketamine diluted in the culture medium (1, 3, 10, 30, 100, 300, 1000, 2000, 3000 μM) for 24 h to compare neurotoxicity in these two different cell cultures. 2-PMPA is selected to explore the protective effect on ketamine-induced neurotoxicity in these two different cell cultures. Cells are exposed to 2-PMPA (20, 50, 100 μM) half an hour before 10 μM ketamine treatment in neuronal cultures and 2 mM ketamine treatment in neuron–glia mixed cultures for 24 h. Different doses of ketamine chosen in neuronal cultures and neuron–glia mixed cultures are based on the results of cell viability tests[2].

TargetMol Calculator 体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。

母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。

体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。

第一步:请输入动物实验的基本信息
