Abstract
Description
[Technical Field]
[0001] The present invention relates to morphinan derivatives having opioid δ receptor agonistic activity. [Background technology]
[0002] Opioids exert their effects by binding to opioid receptors, which have three subtypes: μ, δ, and κ. Agonists for all three subtypes are known to have analgesic effects. However, while morphine, an agonist with high affinity for the opioid μ receptor, has a strong analgesic effect, it also has side effects such as dependence, drug abuse, tolerance, respiratory depression, constipation due to inhibition of gastrointestinal motility, nausea and vomiting, decreased blood pressure, bradycardia, suppression of the cough reflex, and drowsiness. Eptazocine, a selective agonist of the opioid kappa receptor, has a strong analgesic effect, but causes dependence, tolerance, drowsiness, constipation, and mild respiratory depression, while also causing sweating, nausea, vomiting, and dry mouth. On the other hand, activation of the opioid δ receptor is known to produce analgesic, antidepressant, and anxiolytic effects. For example, enkephalin, an endogenous ligand of the opioid δ receptor, is known to have analgesic properties. Furthermore, receptor-deficient mice exhibit increased anxiety-like and depressive-like behaviors (Non-Patent Document 1), and enhancement of the enkephalin-δ receptor system is known to be involved in emotional regulation (Non-Patent Document 2). Furthermore, the antidepressant and anxiolytic effects of various δ receptor agonists are antagonized by δ receptor antagonists in various anxiety and depression models in rats and mice, demonstrating the usefulness of selective δ receptor agonists as antidepressant and anxiolytic drugs (Non-Patent Documents 3-7, Patent Document 1, Patent Document 2). Agonists that selectively activate the opioid δ receptor are expected to have little or no side effects that manifest through activation of the opioid μ receptor or opioid κ receptor. In addition, activation of the δ receptor has been suggested to have an ameliorative effect on neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease, ischemia, stroke, dysuria, HIV infection, alcoholism, diabetes, etc. (Non-Patent Document 8). Various compounds have been reported as opioid δ agonists, and their analgesic, antidepressant, and anxiolytic effects have been demonstrated (Patent Documents 1 to 6, Non-Patent Document 9). Some opioid δ agonists, such as SNC80 and BW373U86, have been reported to induce convulsions (Non-Patent Documents 5, 6, and 10). In addition to the classic tricyclic antidepressants and monoamine oxidase inhibitors, tetracyclic antidepressants and triazolopyridine antidepressants have been developed. In recent years, selective serotonin reuptake inhibitors (SSRIs), serotonin-noradrenaline reuptake inhibitors (SNRIs), and noradrenergic and specific serotonergic antidepressants (NaSSAs) have become popular. However, none of these antidepressants are particularly effective in terms of remission rates. Furthermore, their usefulness is limited by the risk of increased aggression early after initiation of treatment and an increased risk of suicidal ideation and suicide attempts in younger patients. Benzodiazepines are widely used as anti-anxiety drugs, but these drugs have unresolved issues, such as dependency at normal doses, hypnotic effects, muscle relaxation, sedation, and cognitive impairment, making them difficult to use in elderly people and patients with poor general health. Recently, SSRIs and SNRIs, which were developed as antidepressants, have been expanded to treat various anxiety disorders, but they do not provide immediate relief and can have adverse effects. Furthermore, anesthetics such as barbiturates also have anxiolytic effects, but are dangerous because their effective doses are close to the lethal dose. Therefore, there is a need for the development of anti-anxiety drugs and anti-depressants that exert their effects through a mechanism of action different from that of currently used drugs and that have improved side effects and safety.

Example 40 Opioid receptor function test The functional activity of the compounds provided by the present invention at μ, δ, and κ opioid receptors was examined. Methods: The Lance Ultra cAMP kit (PerkinElmer) was used and assays were performed according to the prescribed method. To evaluate agonist activity, CHO cells expressing each human opioid receptor (δ, μ, and κ; accession numbers and catalog numbers are listed below) were incubated with the test compound in the presence of 10 μM forskolin in assay buffer (1×HBSS, 1 M HEPES, pH 7.4, 250 mM IBMX (Isobutylmethylxanthine), 7.5% BSA) for 30 minutes. The cAMP detection reagent included in the kit was then added, and time-resolved fluorescence measurements were performed one hour later using an EnVision plate reader (PerkinElmer). The test compound and each control drug (δ: SNC80, μ: DAMGO, κ: U-69593) were incubated for 10 min. -12 ~10 -5 The test compound was evaluated over a range of concentrations, and the dose-response curve was calculated from the fluorescence value at 665 nm. 50 value and E max The value was calculated. max The values were calculated as the percentage of the maximum response of the test compound when the maximum response of each control drug was taken as 100%.

[0133] NC: Maximum response was not achieved at the highest concentration (10 μM), so ED 50 The value was not calculated. * : Because the maximum response was not achieved at the highest concentration, the response rate at the highest concentration is shown as a reference value. As shown in Table 6, it was confirmed that the compounds of the present invention have potent agonist activity against opioid δ receptors, and have no or only very weak agonist activity against μ and κ receptors. Example 41 Mouse elevated plus maze test (Test Method) Male C57BL / 6N mice aged 5-6 weeks were used for the study. A 40-cm-high plus-maze apparatus was used, consisting of an open-ended runway (6 cm wide, 30 cm long) and a walled runway (6 cm wide, 30 cm long, with walls 15 cm high). Mice were placed facing the walled runway and allowed to enter the plus-maze spontaneously. The test substance was dissolved in saline or 0.005 N HCl-saline and administered subcutaneously to the back 30 minutes before the start of the test. A video camera was started to record the mouse's exploratory behavior at the start of the test, and the test began when the mouse entered the plus-maze. The video footage was used to determine the time spent in each runway, and the percentage of time spent in the open-ended runway (%) was calculated. (Test results) As shown in Figures 1 and 2, in this experiment, Compounds 1 (compound described in Example 1) and 7 (compound described in Example 7) significantly increased the percentage of time spent in the wall-free lane at subcutaneous administration of 3 mg / kg and 10 mg / kg, respectively, demonstrating anxiolytic effects. Furthermore, Compounds 3 (compound described in Example 3), 9 (compound described in Example 9), and 10 (compound described in Example 10) tended to increase the percentage of time spent in the wall-free lane (Figures 3 to 5).
[0134] Example 42 Rat elevated plus maze test The anxiolytic effect of the compounds of the present invention was examined using the rat elevated plus maze test. (Test Method) Male Wistar rats aged 7-9 weeks were used in this study. A 50-cm-high plus-maze apparatus consisted of an open-walled runway (10 cm wide, 50 cm long) and a walled runway (10 cm wide, 50 cm long, with walls 30 cm high). Rats were placed facing the walled runway and allowed to enter the plus-maze spontaneously. Exploratory behavior was observed for 5 minutes. The test substance was dissolved in a 4.5% cyclodextrin solution and orally administered 2 hours before the start of the study. Test data were automatically analyzed using video image behavioral analysis software (PanLab Smart 3.0, PanLab SL), and the percentage of time spent in the open runway (%) was calculated. (Test results) As shown in Figure 6, in this experiment, compounds 7 (compound described in Example 7), 3 (compound described in Example 3), and 10 (compound described in Example 10) significantly increased the percentage of time spent in the wall-free lane when administered orally at 3 mg / kg, demonstrating anxiolytic-like effects. Example 43 hERG (human ether-a-go-go related gene) potassium channel inhibition test (Test Method) Tests were performed using CHO cells stably expressing the hERG channel (purchased from the Channelopathy Foundation) using a Port-a-Patch autopatch clamp apparatus (Nanion Technologies). hERG currents were measured by holding the cell membrane potential at -80 mV and then administering a +20 mV depolarizing pulse for 1.5 seconds followed by a -50 mV test pulse for 1.5 seconds every 10 seconds. The tail currents induced by the test pulses were monitored. Test compounds were dissolved in extracellular solution (137 mM NaCl, 4 mM KCl, 1.8 mM CaCl2, 1 mM MgCl2, 10 mM D(+)-glucose, 10 mM HEPES, pH 7.4) and perfused for 5 minutes at room temperature. Percent inhibition was calculated as the percentage of the tail current after compound application relative to the maximum tail current before compound application (100%). For the test, cells with a peak tail current of 300 pA or more, a tail current run-down of less than 10% of the initial current value, and a leak current of less than 200 pA were used. (Test results) Table 7 shows the test results. In the table, compounds 1, 3, 7, 9, and 10 are compounds described in Examples 1, 3, 7, 9, and 10, respectively. As is clear from Table 7, all of the test compounds exhibited only weak inhibitory effects. On the other hand, it was found that the compounds described in WO 2013 / 35833 (Patent Document 4) include compounds with strong hERG inhibitory activity.

[0136] Comparative Compound 1: Example 93 (Compound 104) of WO 2013 / 35833 Comparative Compound 2: Example 205 (Compound 267) of WO 2013 / 35833 Example 44 Hyperemotional response inhibition test in olfactory bulbectomized (OBX) rats (Test Method) Saitoh et al.'s method (Saitoh A, Yamada M, Yamada M, Takahashi K, Yamaguchi K, Murasawa H, Nakatani A, Tatsumi Y, Hirose N, Kamei J: Antidepressant-like effects of the delta-opioid receptor agonist SNC80 ([(+)-4-[(alphaR)-alpha-[(2S,5R)-2,5-dimethyl-4-(2-propenyl)-1-piperazinyl] -(3-methoxyphenyl)methyl]-N,N-diethylbenzamide) in an olfactory bulbectomized rat model. Brain Res. 2008 OBX rats were generated by surgically removing the olfactory bulb and then rearing them in isolation according to the [1208:160-169] standard. Emotional hyperactivity was assessed 14 days after surgery before group allocation and 2 hours after administration on days 1, 4, 7, 10, and 14 according to the criteria for evaluating emotional hyperactivity established by Gomidata et al. (Gomida et al.: Behavioral pharmacological and electroencephalographic studies of 7-chloro-1-methyl-5-phenyl-1H-1, 5-benzodiazepine-2, 4-(3H, 5H:)-dione (clobazam). Japanese Journal of Pharmacology 82, 267 (1983)). The drug was administered subcutaneously once daily for 14 consecutive days. Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), was used as a positive control. 1% cyclodextrin (CD) was used as the vehicle. (Test results) Administration of 0.1 mg / kg of the test substance (the compound described in Example 7 above) significantly reduced the emotional hyperreactivity of OBX rats compared to the vehicle-treated group from day 4 of administration, and by day 7 of administration, the level had recovered to the same level as that of the sham-operated rats. Administration of 1 mg / kg of the test substance significantly reduced the emotional hyperreactivity of OBX rats compared to the vehicle-treated group from day 1 of administration, and by day 4 of administration, the level had recovered to the same level as that of the sham-operated rats. These effects were sustained until day 14. On the other hand, administration of 10 mg / kg of fluoxetine significantly reduced the emotional hyperreactivity of OBX rats compared to the vehicle-treated group on day 14 of administration. These findings suggest that the test substance, unlike SSRIs, may exhibit antidepressant-like effects from a single dose. Furthermore, it is possible that tolerance to the antidepressant-like effects of the test substance may not develop.
[0137] Example 45 Reserpine-induced Parkinson's disease model mouse (Test Method) ICR male mice (5 weeks old: Japan SLC) were obtained and used after an acclimation period (5-12 days). The PD model was created based on the report by Hille et al. (Exp Neurol. 2001, 172:189). Reserpine (5 mg / kg) was administered intraperitoneally 18-24 hours before the start of the test. On the day of the test, the test compound was administered subcutaneously, and the animals were immediately placed in a locomotor activity cage and the distance traveled was measured for 60 minutes. (Test results) Administration of 10 mg / kg of the test substance (the compound described in Example 7 above) showed a significant increase in exploratory behavior and also showed a tendency to increase rearing behavior, although this was not significant (P=0.16), suggesting that the test substance has a therapeutic effect on Parkinson's disease.
[0138] Example 46 Evaluation using a rat model of cerebral infarction-induced overactive bladder (Test Method) A transient middle cerebral artery occlusion model was created using 8-week-old male SD rats under isoflurane inhalation anesthesia. The next day, a small neck incision was made again under isoflurane inhalation anesthesia, and a catheter for administration was placed in the jugular vein and guided to the back. Cystometry surgery was also performed, and the other end of the cannula inserted into the bladder was guided to the back and connected to a sieve. Four days after cerebral ischemic surgery, cystometry measurements were performed without anesthesia and without restraint. After a stable period of measurement, vehicle was intravenously administered to the bladder, and pre-administration values for the test substance were measured for approximately 30 minutes. Subsequently, the test substance was administered intravenously at approximately 30-minute intervals, starting with the lowest dose, and post-administration values were measured for approximately 30 minutes. Animals that were determined to have frequent urination (urination intervals of 10 minutes or less) in the pre-administration measurements were used, and resting pressure, micturition pressure, micturition interval, and single voided volume at each time point were calculated. (Test results) The measurement results are shown in Table 8. As is clear from Table 8, the test substance (the compound described in Example 7 above) did not affect the resting pressure or micturition pressure at any dose. On the other hand, the micturition interval and the single micturition volume tended to increase in a dose-dependent manner, suggesting that the test substance has an effect of improving frequent urination.

The residual rate at 0 hours of reaction was set to 100%, and the residual rate after incubation was plotted log-linearly against time, and the regression line (y = 100e -kt , k = linear slope: elimination rate constant) was calculated and metabolic clearance CL was calculated using the following formula: int(mL / min / kg) was calculated. CL int * = k (-min) × 52.5 (mg MS protein / g liver) × 26 (g liver / kg) / MS protein (mg MS protein / mL) *: Davies, B. and Morris, T.: Physiological parameters in laboratory animals and humans.
