2-PMPA
Based on 6 publication(s) in Google Scholar
2-PMPA (2-(Phosphonomethyl)pentanedioic acid) is a glutamate carboxypeptidase II (GCPII) inhibitor with an IC50 of 0.0003 μM. 2-PMPA shows low blood-brain barrier penetration. 2-PMPA sodium blocks the hydrolysis of NAAG, regulates glutamate levels in the brain and neurovascular coupling. 2-PMPA is applicable to the research of neurological diseases.

2-PMPA remains stable in rat plasma when stored at room temperature for 4 h, subjected to 3 freeze-thaw cycles, stored at -80°C for 28 days, and placed in a 10°C autosampler for 18 h[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
2-PMPA (80 mg/kg; i.p.; single dose) exerts no significant effects on motor coordination or cognitive ability in Swiss-Webster mice within 24 hours[1].
2-PMPA (100 mg/kg; intraperitoneal injection; single dose) is rapidly absorbed in male Wistar rats, with low brain penetration (a brain/plasma AUC0-t ratio of 0.018), while it shows higher penetration in peripheral nerve tissues[2].

Solvent & Solubility
H2O : 100 mg/mL (442.24 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (stored under nitrogen, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
