Behavioural effects of a selective NMDA NR1A/2B receptor antagonist in rats with unilateral 6-OHDA+parafascicular lesions
Brain Res Bull 2009 Feb 16;78(2-3):91-6.PMID:19007866DOI:10.1016/j.brainresbull.2008.10.004.
Experimental lesions involving the parafascicular (Pf) nucleus and medial forebrain bundle (MFB) may model to some extent the pathological loss of glutamatergic neurons from the centromedian-parafascicular (CM-Pf) complex and nigral dopaminergic cell loss observed clinically at post-mortem in Parkinson's disease (PD) cases. Our study investigated whether there were alterations in symptomatology in such rats with unilateral 6-OHDA+Pf lesions after treatment with either a selective NR1A/NR2B NMDA antagonist and/or l-dopa. Rats were given dual surgery to the MFB with 6-hydroxydopamine (6-OHDA) and Pf with N-methyl-d-aspartate (NMDA). (i) An NR1A/NR2B selective NMDA antagonist (BZAD-01; 10mg/kg), (ii) l-dopa (25mg/kg), (iii) BZAD-01+l-dopa (10mg/kg; 25mg/kg) or (iv) vehicle solution were administered for 6 weeks, during which behavioural testing was performed. BZAD-01 improved postural asymmetry in the first month as well as apomorphine-induced rotation. The latter was also improved by l-dopa in this model. These data support the use of selective NR1/NR2B NMDA antagonists in the therapeutics of PD.
Neuroprotective effects of a selective N-methyl-D-aspartate NR2B receptor antagonist in the 6-hydroxydopamine rat model of Parkinson's disease
Clin Exp Pharmacol Physiol 2008 Nov;35(11):1388-94.PMID:18785982DOI:10.1111/j.1440-1681.2008.05046.x.
1. Current pharmacotherapies for the treatment of Parkinson's disease (PD) are largely symptomatic and do not attenuate the characteristic nigral (dopamine) cell loss. 2. Using the 6-hydroxydopamine (6-OHDA) rat model of PD, we investigated the novel, potentially neuroprotective compound BZAD-01, which is an N-methyl-D-aspartate (NMDA) glutamate receptor antagonist selective for the NR2B subunit. 3. Forty female Sprague-Dawley rats were pretreated with either 10 mg/kg BZAD-01 or vehicle (5% sucrose and 0.1% ascorbate) in their drinking water for 11 days prior to and for 3 days following 6-OHDA surgery. During surgery, rats received an injection of either a toxic dose of 16 microg 6-OHDA or a non-toxic dose of 1 microg 6-OHDA (sham) into the medial forebrain bundle. A series of behavioural tests, including curling (measuring body axis bias), head position bias and narrow beam, was performed fortnightly for 8 weeks after surgery to assess the effects of BZAD-01 pretreatment on parkinsonism. Drug-induced rotational asymmetry was also assessed just before rats were killed. Post-mortem immunohistochemistry was performed to quantify the degree of nigral dopamine cell loss. 4. Pretreatment of 6-OHDA-lesioned rats with BZAD-01 significantly reduced the amount of dopamine cell loss and significantly improved all behavioural measures. Furthermore, there was no significant difference in any of the behavioural measures between lesioned rats pretreated with BZAD-01 and rats that underwent sham surgery.
Evaluation of behavioural effects of a selective NMDA NR1A/2B receptor antagonist in the unilateral 6-OHDA lesion rat model
Brain Res Bull 2009 Feb 16;78(2-3):85-90.PMID:18822357DOI:10.1016/j.brainresbull.2008.08.023.
The degeneration of the dopaminergic nigrostriatal pathway in Parkinson's disease (PD) is associated with altered transmission at striatal NMDA receptors containing NR2B subunits. We investigated a potential novel therapeutic compound, 4-trifluoromethoxy-N-(2-trifluoromethyl-benzyl)-benzamidine (BZAD-01), a selective NMDA NR1A/2B receptor antagonist for PD and compared it with levodopa, the standard treatment for PD. This study also evaluated whether combining levodopa and BZAD-01 gave better improvements of parkinsonian symptoms. Parkinsonism was induced by microinjection of the toxin, 6-hydroxydopamine (6-OHDA) into the medial forebrain bundle (MFB) of 40 Sprague-Dawley rats. Parkinsonism and the efficacy of drugs were assessed using a battery of behavioural tests including balance beam, apomorphine-induced rotation, body axis bias or "curling", head position bias and disengage sensorimotor latency test. Immunohistochemistry was performed on post-mortem tissue to estimate the loss of dopaminergic neurons. The main effects were that BZAD-01 co-administration prevented chronic levodopa-induced potentiation of apomorphine rotation. However levodopa-treated rats were slower than either controls or BZAD-01-treated rats in the locomotor test. The improvement in the apomorphine rotation test suggests that BZAD-01 may be a useful adjunct to levodopa monotherapy.
