Background on PMPA (NAALADase inhibitor)

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].

Neuroprotection produced by the NAALADase inhibitor 2-PMPA in rat cerebellar neurons.[Pubmed:10940354]

Eur J Pharmacol. 2000 Aug 18;402(1-2):31-7.

The present study examined the neuroprotective actions of the N-acetylated-alpha-linked-acidic dipeptidase (NAALADase) inhibitor 2-(phosphonomethyl)pentanedioic acid (2-PMPA) in four in vitro models of neurotoxicity. Using neuron-enriched primary cultures derived from rat embryo (E15) cerebellum, 2-PMPA afforded 100% neuroprotection from injuries induced by hypoxia (EC(50)=8.4 microM). In contrast, against glutamate or N-methyl-D-aspartate (NMDA) injury, 2-PMPA was less potent and its efficacy limited to a maximum of 46% and 16%, respectively. 2-PMPA was not effective against veratridine-induced injury. Also, the less potent analog of 2-PMPA, 2-[phosphonomethyl]succinic acid (2-PMSA), was ineffective. Unlike 2-PMPA, the endogenous NAALADase substrate and mGlu(3) receptor agonist N-acetyl-aspartyl-glutamate (NAAG) was neuroprotective against all four injury mechanisms and compared to 2-PMPA, exhibited a different "phosphate effect" on neuroprotection. These results confirm the superior efficacy of 2-PMPA to protect against injury caused by cellular anoxia, and are discussed relative to upstream modulation of hyperglutamatergic activity vs. downstream modulation of metabotropic receptors as possible targets for ischemia/stroke therapy.

Binding of the glutamate carboxypeptidase II (NAALADase) inhibitor 2-PMPA to rat brain membranes.[Pubmed:11557259]

Eur J Pharmacol. 2001 Sep 14;427(2):91-6.

2-Phosphonomethyl pentanedioic acid (2-PMPA) is a potent and selective inhibitor of glutamate carboxypeptidase II (NAALADase), and has shown robust neuroprotective activity in both in vitro and in vivo models of ischemia. In the brain, glutamate carboxypeptidase II (GCPII) (EC3.4.17.21) hydrolyzes the neuropeptide N-acetylaspartylglutamate (NAAG) to glutamate and N-acetylaspartate. We report the development and characterization of a [(3)H]2-PMPA binding assay. [(3)H]2-PMPA binding was dependent on protein concentration, saturable, and displaceable. The association (k(on)) and dissociation (k(off)) rate constants were 3x10(6) M(-1) s(-1) and 0.01 s(-1), respectively. The dissociation equilibrium constant (K(d)) determined from the ratio of the rate constants (K(d)=k(off)/k(on)) was 1 nM. Scatchard analysis revealed one binding site with K(d)=2 nM and B(max)=0.7 pmol/mg. Binding exhibited similar pharmacological properties to GCPII enzyme activity, including chloride dependency, cobalt stimulation and inhibition by phosphate and quisqualate. The binding of [(3)H]2-PMPA also showed tissue specificity in that tissues previously reported to be devoid of GCPII enzymatic activity were devoid of [(3)H]2-PMPA binding. [(3)H]2-PMPA binding represents an additional probe for the study of GCPII activity, and may be useful as a high throughput screening assay.

Morphine tolerance and reward but not expression of morphine dependence are inhibited by the selective glutamate carboxypeptidase II (GCP II, NAALADase) inhibitor, 2-PMPA.[Pubmed:12629525]

Neuropsychopharmacology. 2003 Mar;28(3):457-67.

Inhibition of glutamate carboxypeptidase II (GCP II; NAALADase) produces a variety of effects on glutamatergic neurotransmission. The aim of this study was to investigate effects of GCP II inhibition with the selective inhibitor, 2-PMPA, on: (a) development of tolerance to the antinociceptive effects, (b) withdrawal, and (c) conditioned reward produced by morphine in C57/Bl mice. The degree of tolerance was assessed using the tail-flick test before and after 6 days of twice daily (b.i.d.) administration of 2-PMPA and 10 mg/kg of morphine. Opioid withdrawal was measured 3 days after twice daily morphine (30 or 10 mg/kg) administration, followed by naloxone challenge. Conditioned morphine reward was investigated using conditioned place preference with a single morphine dose (10 mg/kg). High doses of 2-PMPA inhibited the development of morphine tolerance (resembling the effect of 7.5 mg/kg of the NMDA receptor antagonist, memantine) while not affecting the severity of withdrawal. A high dose of 2-PMPA (100 mg/kg) also significantly potentiated morphine withdrawal, but inhibited both acquisition and expression of morphine-induced conditioned place preference. Memantine inhibited the intensity of morphine withdrawal as well as acquisition and expression of morphine-induced conditioned place preference. In addition, 2-PMPA did not affect learning or memory retrieval in a simple two-trial test, nor did it produce withdrawal symptoms in morphine-dependent, placebo-challenged mice. Results suggest involvement of GCP II (NAALADase) in phenomena related to opioid addiction.
