Description

[Technical field]

[0001] The present invention relates to a Ca-containing N-pyridyl urea derivative. 2+ The present invention relates to a pharmaceutical composition for use in the treatment or prevention of a disease or disorder caused by activation of calmodulin-dependent kinase II, particularly a pharmaceutical composition for use in improving cognitive function, and a method for treating or preventing a disease associated with cognitive impairment using the compound. [Background technology]

[0002] N-methyl-D-aspartate (NMDA) receptors (NMDA receptors, NMDARs), which are glutamate-gated cation channels in neurons, are known to regulate synaptic plasticity, which is the basis of neural development, connectivity, and cognition, through their abundance and activity. NMDA receptors are distributed ubiquitously throughout the brain, and NMDA receptors have properties that are distinct from the other major subtypes of ionotropic glutamate receptors (AMPA and kainate receptors). Mammalian NMDA receptors are thought to be composed of four subunits, consisting of two sets of heterodimers of GluN1 and GluN2, with a glycine-binding site on the GluN1 subunit and a glutamate-binding site on the GluN2 subunit. Four types of GluN2 subunits have been cloned, GluN2A, GluN2B, GluN2C, and GluN2D, and each has different expression sites and timing in vivo. There have been reports on the regulation of NMDA receptors via GluN2B (Patent Documents 1 and 2).

[0003] Ca 2+ Calmodulin-dependent protein kinase II (CaMKII) is a Ca 2+CaMKII is a serine / threonine-specific protein kinase controlled by the NR2A / calmodulin complex, and is known to be involved in many signal transduction cascades and is thought to play an important role in the plasticity of synaptic transmission and higher brain functions including learning and memory. It has been reported that the binding of CaMKII to GluN2B is involved in signal transduction, particularly in the long-term potentiation (LTP) phenomenon of synaptic responses (Non-Patent Documents 1-3). It has also been reported that GluN2A of CaMKII is involved in LTP (Non-Patent Document 2). Genome-wide association analysis has suggested that NR2A of CaMKII is strongly correlated with schizophrenia, depression, and the like (Non-Patent Document 4).

[0004] There have been many reports on N-pyridyl urea derivatives having pharmaceutical activity (for example, Patent Documents 3 and 4). There has also been a report on a method for synthesizing N-pyridyl urea derivatives (Non-Patent Document 6). [Prior art documents] [Patent documents]

[0055] [ka]

[0056] Under an argon atmosphere, a solution (1.0 mL) of N,N'-bis(4-methoxy-2-pyridyl)urea (compound 1, 0.25 mmol, 68.5 mg) and N,N'-bis(2-methyl-2-pyridyl)urea (compound 2, 0.75 mmol, 181.5 mg) in dehydrated toluene (1.0 mL) was added with separately prepared rhodium hydride tetrakistriphenylphosphine complex (14.4 mg, 5 mol%, Ahmad, N. et al., Inorg. Synth., 15, 58 (1974)) and 1,2-bis(diphenylphosphino)benzene (11.2 mg, 10 mol%) at room temperature, and the mixture was heated to reflux for 3 hours. Then, the solvent was distilled off under reduced pressure, and the residue was subjected to silica gel column chromatography (hexane:ethyl acetate=5:1) to obtain the title compound (No. 1, 90.5 mg, 70%) as a white solid.

[0075] [ka]

[0076] Under an argon atmosphere, 2-aminobenzoxazole (1 mmol, 134.1 mg) was reacted with phenyl isocyanate (1 mmol, 119.0 mg) in tetrahydrofuran (2 mL) to give N-(2-benzoxazolyl)-N'-phenylurea (234.5 mg, 93%). Next, N,N'-bis(2-pyridyl)urea (0.25 mmol, 53.5 mg), rhodium hydride tetrakistriphenylphosphine complex (14.4 mg, 5 mol%), and 1,2-bis(diphenylphosphino)benzene (11.2 mg, 10 mol%) were added to the obtained N-(2-benzoxazolyl)-N'-phenylurea (0.25 mmol, 63.1 mg) at room temperature, and the mixture was heated to reflux for 3 hours.

[0103] [Test Example 3] Confirmation test of cognitive function improvement effect The cognitive impairment of olfactory bulbectomized mice (OBX mice) (10 weeks old), a model mouse with cognitive impairment, was confirmed by chronic treatment (oral administration) of the test compound (1 mg / kg) once a day for 2 weeks, and a significant improvement in cognitive function was confirmed. The results of the confirmation test are shown in Figure 4a-c. OBX mice were generated using 10-week-old DDY male mice (Nippon SLC, Hamamatsu, Japan). Olfactory bulbectomy surgery was performed under conditions of anesthesia with sodium pentobarbital (50 mg / kg, intraperitoneal administration; Dainippon, Osaka, Japan). The mice were fixed in a brain fixator, and a hole with a diameter of 1 mm was drilled in the skull above the olfactory bulb. The olfactory bulb and prefrontal cortex were aspirated and removed using a suction pump. In the Sham group, the same procedures as in the OBX group were performed except for the aspirated removal of the olfactory bulb.

[0104] Figure 3a-b shows the results of behavioral analysis. Figure 3a shows the results of examining the attention function of sham mice and OBX mice (n=5 each) using the conventional Y-maze method, and treatment with the test compound (1mg / kg) showed a significant improvement in attention function. The Y-maze method is a method in which mice are allowed to walk freely through three arms for 8 minutes. If the arms are designated A, B, and C, a mouse in A will enter either arm B or C. If a mouse enters arm B, the mouse will then enter arm C. In this way, entering ABC is considered a correct answer. On the other hand, entering ABA or not entering a new arm is considered an incorrect answer. The positions of the arms that the mouse moved to are recorded in the order of selection, and the number of times the mouse moved to each arm during the measurement time is counted, which is considered to be total arm entries. Furthermore, the number of correct answers (combinations in which three different arms were selected consecutively) was counted, and this number was taken as the number of alternations. The ratio of the number of alternations to the total arm entries minus 2 was expressed as Alternation (%) as an index of normal alternation behavior (correct rate of spatial working memory). *<0.05 (vs. Sham), +<0.05 (vs. OBX) indicate significance. Figure 3b shows the results of a conventional novel object recognition test in which memory for novel objects was measured in sham mice, OBX mice, and OBX mice treated with a test compound (1 mg / kg) (n=5 each), and a significant improvement in memory impairment was observed by treatment with the test compound (1 mg / kg). In the novel object recognition test, two blocks of the same shape were placed in a mouse cage and the mouse was allowed to freely explore the object for 10 minutes (training trial). After 1 hour, one of the blocks was replaced with a novel object, and the mouse was allowed to freely explore the object for another 5 minutes (retention trial). In the training and retention trials, the number of contacts with each of the two objects was measured, and the discrimination index was calculated as the percentage of contacts with the swapped block to the total number of contacts in the retention trial. *<0.05 (vs. Sham), +<0.05 (vs. OBX) indicate significance.
