PMPA is a selective inhibitor of NAALADase with Ki value of 275 pM [1].NAALADase also known as GCPII is a zinc metalloenzyme that resides in membranes and involves in the catalyzing process of neuropeptide NAAG to NAA and glutamate. It has been shown that NAALADase has the highest expression in nervous/ prostatic tissues and cancers and NAALADase inhibition produces a variety of effects on providing neuroprotection, detection, imaging and treatment of prostate cancer [2] [3].PMPA is a potent NAALADase inhibitor and has a more activity than reported NAALADase inhibitor ZJ43. In male C57/Bl mice model, high doses of PMPA inhibited the morphine tolerance development (resembling the effect of 7.5 mg/kg of the NMDA receptor antagonist, memantine) while had no effect on severity of withdrawal; 100 mg/kg PMPA also significantly potentiated morphine withdrawal, but inhibited both acquisition and expression of morphine-induced conditioned place preference which suggested NAALADase involves in phenomena related to opioid addiction [4]. PMPA treatment increased the mice latency to enter the dark box during the training day and at the dose of 150 mg/kg PMPA treatment impaired spontaneous alternation and reduced locomotion in Y-maze task which demonstrated that PMPA affected mice learning and memory tasks through NAALADase inhibition [5].References: [1].
