Definitions

  • the present invention relates to substituted dimethylcyclobutyl compounds of general formula I,
  • medicaments comprising said substituted dimethylcyclobutyl compounds as well as the use of said substituted dimethylcyclobutyl compounds for the preparation of medicaments, which are particularly suitable for the prophylaxis and/or treatment of disorders or diseases that are at least partially mediated via sigma receptors.
  • sigma receptor ligands may be useful in the treatment of psychosis and movement disorders such as dystonia and tardive dyskinesia, and motor disturbances associated with Huntington's chorea or Tourette's syndrome and in Parkinson's disease (Walker, J. M. et al, Pharmacological Reviews, 1990, 42, 355). It has been reported that the known sigma receptor ligand rimcazole clinically shows effects in the treatment of psychosis (Snyder, S. H., Largent, B. L. J. Neuropsychiatry 1989, 1 , 7). The sigma binding sites have preferential affinity for the dextrorotatory isomers of certain opiate benzomorphans, such as (+)SKF 10047, (+)cyclazocine, and
  • (+)pentazocine and also for some narcoleptics such as halopehdol.
  • the sigma receptor has at least two subtypes, which may be discriminated by stereoselective isomers of these pharmacoactive drugs. Possible sigma- site-mediated drug effects include modulation of glutamate receptor function, neurotransmitter response, neuroprotection, behaviour, and cognition (Quirion, R. et al. Trends Pharmacol. Sci., 1992, 13:85-86). Most studies have implied that sigma binding sites (receptors) are plasmalemmal elements of the signal transduction cascade. Drugs reported to be selective sigma ligands have been evaluated as antipsychotics (Hanner, M. et al. Proc. Natl.
  • an object of the present invention was to provide compounds that are particularly suitable as active ingredients in medicaments, especially in medicaments for the prophylaxis and/or treatment of disorders or diseases related to sigma receptors, preferably sigma-1 receptors, such as food intake related disorders or pain.
  • the substituted dimethylcyclobutyl compounds of general formula I given below show good to excellent affinity for sigma receptors, in particular they show good to excellent affinity to sigma-1 receptors.
  • These compounds are therefore particularly suitable as pharmacologically active agents in a medicament for the prophylaxis and/or treatment of disorders or diseases related to sigma receptors, preferably related to sigma-1 receptors.

I,
a process for their preparation, medicaments comprising said substituted dimethylcyclobutyl compounds as well as the use of said substituted dimethylcyclobutyl compounds for the preparation of medicaments, which are particularly suitable for the prophylaxis and/or treatment of disorders or diseases that are at least partially mediated via sigma receptors.
The search for new therapeutic agents has been greatly aided in recent years by better understanding of the structure of proteins and other biomolecules associated with target diseases. One important class of these proteins is the sigma receptor, a cell surface receptor of the central nervous system (CNS) which may be related to the dysphoric, hallucinogenic and cardiac stimulant effects of opioids.
From studies of the biology and function of sigma receptors, evidence has been presented that sigma receptor ligands may be useful in the treatment of psychosis and movement disorders such as dystonia and tardive dyskinesia, and motor disturbances associated with Huntington's chorea or Tourette's syndrome and in Parkinson's disease (Walker, J. M. et al, Pharmacological Reviews, 1990, 42, 355). It has been reported that the known sigma receptor ligand rimcazole clinically shows effects in the treatment of psychosis (Snyder, S. H., Largent, B. L. J. Neuropsychiatry 1989, 1 , 7). The sigma binding sites have preferential affinity for the dextrorotatory isomers of certain opiate benzomorphans, such as (+)SKF 10047, (+)cyclazocine, and
(+)pentazocine and also for some narcoleptics such as halopehdol.
The sigma receptor has at least two subtypes, which may be discriminated by stereoselective isomers of these pharmacoactive drugs. Possible sigma- site-mediated drug effects include modulation of glutamate receptor function, neurotransmitter response, neuroprotection, behaviour, and cognition (Quirion, R. et al. Trends Pharmacol. Sci., 1992, 13:85-86). Most studies have implied that sigma binding sites (receptors) are plasmalemmal elements of the signal transduction cascade. Drugs reported to be selective sigma ligands have been evaluated as antipsychotics (Hanner, M. et al. Proc. Natl.
Acad. Sci., 1996, 93:8072-8077). The existence of sigma receptors in the CNS, immune and endocrine systems have suggested a likelihood that it may serve as link between the three systems.
Thus, there is a need to find compounds that have pharmacological activity towards the sigma receptor, being both effective and selective, and having good "drugability" properties, i.e. good pharmaceutical properties related to administration, distribution, metabolism and excretion.
Therefore an object of the present invention was to provide compounds that are particularly suitable as active ingredients in medicaments, especially in medicaments for the prophylaxis and/or treatment of disorders or diseases related to sigma receptors, preferably sigma-1 receptors, such as food intake related disorders or pain. Surprisingly, it has been found that the substituted dimethylcyclobutyl compounds of general formula I given below show good to excellent affinity for sigma receptors, in particular they show good to excellent affinity to sigma-1 receptors. These compounds are therefore particularly suitable as pharmacologically active agents in a medicament for the prophylaxis and/or treatment of disorders or diseases related to sigma receptors, preferably related to sigma-1 receptors.
Thus, in one of its aspects the present invention relates to a dimethylcyclobutyl compound of general formula I,

PHARMACOLOGICAL METHODS:
Some representative compounds of the invention were tested for their activity as sigma (sigma-1 and sigma-2) inhibitors. The following protocols were followed:
Sigma-1 receptor binding
Brain membrane preparation and binding assays for the sigma-1 receptor were performed as described (DeHaven-Hudkins et al., Characterization of the binding of [3H]-(+)-pentazocine to recognition sites in guinea pig brain, Eur. J. Pharmacol. 227, 371-378) with some modifications.
In brief, guinea pig brains were homogenized in 10 vols. (w/v) of Tris-HCI 50 mM, 0.32 M sucrose, pH 7.4, with a Kinematica Polytron PT 3000 at 15000 r.p.m. for 30 s. The homogenate was centhfuged at 1000 g for 10 min at 4 0C and the supernatants collected and centrifuged again at 48000 g for 15 min at 4 0C. The pellet was resuspended in 10 volumes of Tris-HCI buffer (50 mM, pH 7.4), incubated at 37 0C for 30 min, and centrifuged at 48000 g for 20 min at 4 0C. Following this, the pellet was resuspended in fresh Tris-HCI buffer (50 mM, pH 7.4) and stored on ice until use.
Each assay tube contained 10 μL of [3H]-(+)-pentazocine (final concentration of 0.5 nM), 900 μL of the tissue suspension to a final assay volume of 1 mL and a final tissue concentration of approximately 30 mg tissue net weight/mL. Non-specific binding was defined by addition of a final concentration of 1 M haloperidol. All tubes were incubated at 37 0C for 150 min before termination of the reaction by rapid filtration over Schleicher & Schuell GF 3362 glass fibre filters [previously soaked in a solution of 0,5% polyethylenimine for at least 1 h]. Filters were then washed with four times with 4 ml_ of cold Tris-HCI buffer (50 mM, pH 7.4). Following addition of scintillation cocktail, the samples were allowed to equilibrate overnight. The amount of bound radioactivity was determined by liquid scintillation spectrometry using a Wallac Winspectral 1414 liquid scintillation counter. Protein concentrations were determined by the method of Lowry et al. (Protein measurement with the FoNn phenol reagent, J. Biol. Chem, 193, 265).
Sigma-2 receptor binding
Binding studies for sigma-2 receptor were performed as described (Radesca et al., Synthesis and Receptor Binding of Enantiomeric N-Substituted cis-N- [2-(3,4-Dichlorophenyl)ethyl]-2-(1 -pyrrolidinyl)ciclohexylamines as High- Affinity Receptor Ligands, J. Med. Chem. 34, 3065-3074) with some modifications. In brief, brains from sigma receptor type I (sigma-1 ) knockout mice (Langa, F., Codony X., Tovar V., Lavado A., Gimenez E., Cozar P., Cantero M., Dordal A., Hernandez E., Perez R., Monroy X., Zamanillo D., Guitart X., Montoliu LL, 2003, Generation and phenotypic analysis of sigma receptor type I (Sigmal ) knockout mice, European Journal of Neuroscience, Vol. 18, 2188-2196) were homogenized in a volume of 10 mL/g tissue net weight of ice-cold 10 mM Tris-HCI, pH 7.4, containing 320 mM sucrose (Tris- sucrose buffer) with a Potter-Elvehjem homogenizer (10 strokes at 500 r.p.m.) The homogenates were then centrifuged at 1000g for 10 min at 4 0C, and the supernatants were saved. The pellets were resuspended by vortexing in 2 mL/g ice-cold Tris-sucrose buffer and centrifuged again at
1000 g for 10 min. The combined 1000g supernatants were centrifuged at 31000 g for 15 min at 4 0C. The pellets were resuspended by vortexing in 3 mL/g 10 mM Tris-HCI, pH 7.4, and the suspension was kept at 25 0C for 15 min. Following centrifugation at 31000 g for 15 min, the pellets were resuspended by gentle Potter Elvehjem homogenisation to a volume of 1.53 mL/g in 1 O mM Tris-HCI pH 7.4.
The assay tubes contained 10 μL of [3H]-DTG (final concentration of 3 nM), 400 μL of the tissue suspension (5.3 mL/g in 50 mM Tris-HCI, pH 8.0) to a final assay volume of 0.5 mL. Non-specific binding was defined by addition of a final concentration of 1 M halopehdol. All tubes were incubated at 25 0C for
120 min before termination of the reaction by rapid filtration over Schleicher & Schuell GF 3362 glass fibre filters [previously soaked in a solution of 0,5% polyethylenimine for at least 1 h]. Filters were washed with three times with 5 mL volumes of cold Tris-HCI buffer (10 mM, pH 8.0). Following addition of scintillation cocktail samples were allowed to equilibrate overnight. The amount of bound radioactivity was determined by liquid scintillation spectrometry using a Wallac Winspectral 1414 liquid scintillation counter. Protein concentrations were determined by the method of Lowry et al. (Protein measurement with the FoNn phenol reagent, J. Biol. Chem, 193, 265).
