Biological Activity of VU 0364770

DescriptionPositive allosteric modulator at mGlu4 receptors (EC50 = 290 nM in mGlu4-expressing HEK 293 cells). Reverses haloperidol-induced catalepsy in rats; prevents attentional deficit and forelimb asymmetry in a rodent model of Parkinson's disease. Exhibits affinity for MAO-B and MAO-A (Ki values are 0.72 μM and 8.5 μM respectively). Brain penetrant.

Protocol

Kinase Assay [1]
The effects of VU0364770 on rat mGlu1 and mGlu5 are assessed by using calcium mobilization and measuring the glutamate concentration-response relationship in the presence and absence of 10 μM VU0364770. Using a double-addition protocol, VU0364770 is added to the cells, followed 2.5 min later by a full concentration-response of glutamate. Shifts of the concentration-response relationship are used to assess potential potentiator (left shift of more than 2-fold) or antagonist (right shift of more than 2-fold or depression of the maximum response by at least 75%) activity of VU0364770. Compounds are further assessed for mGlu5 antagonist activity by performing a full concentration-response curve, starting at 30 μM and serially diluted it by using 1:3 dilutions, in the presence of an EC80 concentration of glutamate[1].

Animal Administration [1]
Rats[1] Adult male Sprague-Dawley rats, weighing 250 to 300 g, are used. Rat are examined for catalepsy 30 min after the administration of either VU0364770 (1-56.6 mg/kg s.c.), VU0364772 (1-56.6 mg/kg s.c.), A2A antagonist (56.6 mg/kg p.o.), Preladenant (0.03-30 mg/kg p.o.), or vehicle. In the interaction studies rats ate administered VU0364770 (10 or 30 mg/kg) + vehicle, VU0364770 (10 or 30 mg/kg)+Preladenant (0.1-1 mg/kg), or vehicle+Preladenant (0.1-1 mg/kg) 30 min before testing.

[Lessons learned from the evacuation of the VU University Medical Centre after flooding].[Pubmed:28224872]

Ned Tijdschr Geneeskd. 2017;161:D861.

On 8 September 2015, flooding of the lower floors of the VU University Medical Center in Amsterdam caused serious damage to many vital technical services, such as water and power supplies. The decision was made to completely evacuate the university hospital. This paper describes the chronology and events of that day and shares a number of important lessons that were learned, in order to help readers to optimise crisis organisation in their own institutions. A serious situation or disaster can never be standardised in protocols or manuals; flexibility, improvisation and confidence in one another's expertise and commitment are therefore essential.

The metabotropic glutamate receptor 4-positive allosteric modulator VU0364770 produces efficacy alone and in combination with L-DOPA or an adenosine 2A antagonist in preclinical rodent models of Parkinson's disease.[Pubmed:22088953]

J Pharmacol Exp Ther. 2012 Feb;340(2):404-21.

Parkinson's disease (PD) is a debilitating neurodegenerative disorder associated with severe motor impairments caused by the loss of dopaminergic innervation of the striatum. Previous studies have demonstrated that positive allosteric modulators (PAMs) of metabotropic glutamate receptor 4 (mGlu(4)), including N-phenyl-7-(hydroxyimino) cyclopropa[b]chromen-1a-carboxamide, can produce antiparkinsonian-like effects in preclinical models of PD. However, these early mGlu(4) PAMsexhibited unsuitable physiochemical properties for systemic dosing, requiring intracerebroventricular administration and limiting their broader utility as in vivo tools to further understand the role of mGlu(4) in the modulation of basal ganglia function relevant to PD. In the present study, we describe the pharmacologic characterization of a systemically active mGlu(4) PAM, N-(3-chlorophenyl)picolinamide (VU0364770), in several rodent PD models. VU0364770 showed efficacy alone or when administered in combination with L-DOPA or an adenosine 2A (A2A) receptor antagonist currently in clinical development (preladenant). When administered alone, VU0364770 exhibited efficacy in reversing haloperidol-induced catalepsy, forelimb asymmetry-induced by unilateral 6-hydroxydopamine (6-OHDA) lesions of the median forebrain bundle, and attentional deficits induced by bilateral 6-OHDA nigrostriatal lesions in rats. In addition, VU0364770 enhanced the efficacy of preladenant to reverse haloperidol-induced catalepsy when given in combination. The effects of VU0364770 to reverse forelimb asymmetry were also potentiated when the compound was coadministered with an inactive dose of L-DOPA, suggesting that mGlu(4) PAMs may provide L-DOPA-sparing activity. The present findings provide exciting support for the potential role of selective mGlu(4) PAMs as a novel approach for the symptomatic treatment of PD and a possible augmentation strategy with either L-DOPA or A2A antagonists.
