Imidazole derivatives

Abstract

Novel imidazole derivatives are disclosed. These compounds have a good affinity to the NMDA (N-methyl-D-aspartate)-receptor subtype selective blockers, which have a key function in modulating neuronal activity and plasticity which makes them key players in mediating processes underlying development of CNS as well as learning and memory formation. These compounds are useful in the control or treatment of diseases mediated by this receptor.

Description

SUMMARY OF THE INVENTION

The present invention relates to compounds of formula

having valuable CNS, learning and memory forming pharmacological properties.

BACKGROUND OF THE INVENTION

Under pathological conditions of acute and chronic forms of neurodegeneration overactivation of NMDA receptors is a key event for triggering neuronal cell death. NMDA receptors are composed of members from two subunit families, namely NR-1 (8 different splice variants) and NR-2 (A to D) originating from different genes. Members from the two subunit families show a distinct distribution in different brain areas. Heteromeric combinations of NR-1 members with different NR-2 subunits result in NMDA receptors displaying different pharmaceutical properties. Therapeutic indications for NMDA NR-2B receptor subtype specific blockers include acute forms of neurodegeneration caused, e.g., by stroke and brain trauma, and chronic forms of neurodegeneration such as Alzheimer's disease, Parkinson's disease, Huntington's disease, ALS (amyotrophic lateral sclerosis) and neurodegeneration associated with bacterial or viral infections, and, in addition, depression and chronic and acute pain.

Test Method

3 H [R-(R*,S*)]-α-(4-Hydroxy-phenyl)-β-methyl-4-(phenyl-methyl)-1-piperidine propanol) Binding

Male Füllinsdorf albino rats weighing between 150-200 g were used. Membranes were prepared by homogenization of the whole brain minus cerebellum and medulla oblongata with a Polytron (10.000 rpm, 30 seconds), in 25 volumes of a cold Tris-HCl 50 mM, EDTA 10 mM, pH 7.1 buffer. The homogenate was centrifuged at 48,000 g for 10 minutes at 4° C. The pellet was resuspended using the Polytron in the same volume of buffer and the homogenate was incubated at 37° C. for 10 minutes. After centrifugation the pellet was homogenized in the same buffer and frozen at −80° C. for at least 16 hours but not more than 10 days. For the binding assay the homogenate was thawed at 37° C., centrifuged and the pellet was washed three times as above in a Tris-HCl 5 mM, pH 7.4 cold buffer. The final pellet was resuspended in the same buffer and used at a final concentration of 200 mg of protein/ml.

3 H-Ro 25-6981 binding experiments were performed using a Tris-HCI 50 mM, pH 7.4 buffer. For displacement experiments 5 nM of 3 H-Ro 25-6981 were used and non specific binding was measured using 10 mM of tetrahydroisoquinoline and usually it accounts for 10% of the total. The incubation time was 2 hours at 4° C. and the assay was stopped by filtration on Whatmann GF/B glass fiber filters (Unifilter-96, Packard, Zürich, Switzerland). The filters were washed 5 times with cold buffer. The radioactivity on the filter was counted on a Packard Top-count microplate scintillation counter after addition of 40 mL of microscint 40 (Canberra Packard S.A., Zürich, Switzerland).

The effects of compounds were measured using a minimum of 8 concentrations and repeated at least once. The pooled normalized values were analyzed using a non-linear regression calculation program which provide IC 50 with their relative upper and lower 95% confidence limits.

The IC 50 (μM) of preferred compounds of formula I, tested in accordance with the above mentioned methods, is <0.1 μM. In the table below are shown some data for binding activity:
