Definitions

  • the present invention relates to a tricyclic heterocyclic ring compound useful for preventing and/or treating for a disease caused by stress, process for preparation thereof and use thereof.
  • a disease caused by stress means that by psychosocial or physical stress stimulation (stressor), the distortion (response to stress) in the body subjected to these stimulations occurs and any disorders in systemic various areas develop.
  • stressor influences (response to stress) on the activities of nervous system, endocrine system and immune system to void these functions, these influences lead to organic lesions in brain itself or peripheral organs. In case of being subjected to excess stress, it causes diseases leading to marked reduce of quality of life (so-called, QOL).
  • Diseases caused by stress include, for example, central nervous system diseases (e.g. depression etc.), digestive system diseases (e.g. irritable bowel syndrome, gastric ulcer etc.), cardiovascular system diseases (e.g. essential hypertension etc.) and the like.

No. 11/722,623 filed Jun. 22, 2007, which is a 371 of PCT/JP2005/023450 filed Dec. 21, 2005, which claims priority of Japanese Application Nos. 2004-371033 filed Dec. 22, 2004 and 2005-261914 filed Sep. 9, 2005. The above-noted applications are incorporated herein by reference in their entirety.
    • TECHNICAL FIELD
  • The present invention relates to a tricyclic heterocyclic ring compound useful for preventing and/or treating for a disease caused by stress, process for preparation thereof and use thereof.
    • BACKGROUND ART
  • A disease caused by stress means that by psychosocial or physical stress stimulation (stressor), the distortion (response to stress) in the body subjected to these stimulations occurs and any disorders in systemic various areas develop. Concretely, since stressor influences (response to stress) on the activities of nervous system, endocrine system and immune system to void these functions, these influences lead to organic lesions in brain itself or peripheral organs. In case of being subjected to excess stress, it causes diseases leading to marked reduce of quality of life (so-called, QOL).
  • Diseases caused by stress include, for example, central nervous system diseases (e.g. depression etc.), digestive system diseases (e.g. irritable bowel syndrome, gastric ulcer etc.), cardiovascular system diseases (e.g. essential hypertension etc.) and the like. As medicinal drugs for remedy for diseases caused by these stresses, anti depressant drug, anti anxiety drug and drug for symptomatic treatment against organic lesions of peripheral organs (e.g. antacids, gastric mucoprotective drugs etc.) have been developed for the purpose of alleviating psychological stressor. However, these drugs become effective to some extent, but these addictions, side effects or the like frequently develop. At present, the therapy for these diseases comes to definitive therapy. Therefore, the development of the preventing and/or therapeutic drug for diseases caused by stress having highly safety and coming to possible definitive therapeutic drug has been longed for.
  • Meanwhile, there are mitochondrial benzodiazepine receptor (hereinafter, it is abbreviated as MBR) (“Science 198, 849-851, 1977”, “Proc. Natl. Acad. Sci., 89, 3805-3809, 1977”) in mitochondrial outer membrane, which transport cholesterol from intracellular to the internal membrane of mitochondria that is the active site of P-450scc. Steroid synthesized in the brain is called as neurosteroid. Cholesterol, which is the steroid precursor, is converted into pregnenolone metabolized with side-chain cleavage enzyme P-450scc. This process is the first process of steroid production system. However, it has been indicated that this transport process was the rate determining process in steroid production system rather than metabolism with P-450scc. It has been thought that the neurosteroid content in the brain could be adjusted if the function of MBRs could be regulated. It has been thought that as a result of balance between an excitatory signaling system and an inhibitory signaling system was collapsed by neurosteroid content in the brain varying under stress condition, the various stress-related diseases could be caused by changes of activities in nerve system, immune system and endocrine system which were regulated by these nerve systems.
  • As mentioned above, the disrupted balance between an excitatory signaling system and an inhibitory signaling system caused by stressor load can be improved to the desirable balanced condition by the increase or the inhibition of neurosteroid production, which is useful for prevention or treatment for stress-related diseases. Therefore, it is expected that the compounds having affinity for MBRs are extremely useful for prevention and/or treatment for these diseases, if they are supplied
  • As the preventive and/or therapeutic agent for a disease caused by stress, the compound represented by formula (Y):

  • AY-XY—YY—ZY—BY  (Y)
  • (wherein, AY is cyclic group which may have a substituent(s), XY, YY and ZY are each independently single bond or a spacer of which main chain has an atom number of 1-3, BY is hydrocarbon which may have a substituent(s) or cyclic group which may have a substituent(s).), a salt thereof, a N-oxide thereof, a solvate thereof or a prodrug thereof is known to have the affinity to MBRs (see, WO04/113300).

    • Biological Example 1 Receptor Binding Experiment
  • Affinity of the compound of the present invention for MBR was measured using a rat membrana cerebri specimen. The measuring method of the present invention has improved measurement accuracy and measurement sensitivity so as to evaluate the compound of the present invention as follows. A Wistar male rat was decapitated and the whole brain was extirpated, and then the cerebellum was removed. For the rat membrana cerebri specimen used in the binding experiment, 50 mmol/L of an ice-cold tris-hydrochloric acid buffer (pH 7.4) was added and it was homogenized and centrifuged. After the resulting deposit was washed, it was resuspended to be prepared to about 1 mg/ml. The binding experiment was conducted using [3H]PK11195 as an MBR selective ligand.
  • In the case of calculating the all binding amount in a saturation experiment, the membrane specimen, [3H]PK11195 at several concentrations, dimethyl sulfoxide (DMSO) in a final concentration of 0.5 vol %, and 50 mmol/L of a tris-hydrochloric acid buffer (pH 7.4) were mixed (all amount 200 μl), followed by incubation at room temperature for one hour. In the case of calculating the nonspecific binding amount, [3H]PK11195 in a final concentration of 20 μmol/L was added instead of DMSO, followed by incubation for one hour. They were rapidly filtered on a GF/B filter pretreated with 0.3% polyethylenimine using a harvester, and washed with 50 mmol/L of a tris-hydrochloric acid buffer (pH 7.4) twice. After the filter was dried, radioactivity was measured by a liquid scintillation counter. With respect to the data obtained in the binding experiment, a Scatchard analysis was performed using analysis software KELL (Ver.6 BIOSOFT) to calculate a dissociation constant (KD value).
  • In the case of calculating the all binding amount in a competition experiment, the membrane specimen, [3H]PK11195 in a final concentration of 0.5 or 1 nmol/L, DMSO in a final concentration of 0.5 vol %, and 50 mmol/L of a tris-hydrochloric acid buffer (pH 7.4) were mixed (all amount 200 μl), followed by incubation at room temperature for one hour. In the case of calculating the nonspecific binding amount, PK11195 in a final concentration of 20 μmol/L instead of DMSO was added, followed by incubation. In the case of calculating the affinity of the compound of the present invention, a DMSO solution of the present invention in a final concentration of 10 pmol/L to 1 μmol/L instead of DMSO was added, followed by incubation. One hour later, they were sucking filtered in the above method, and the radioactivity on the filter was measured with a liquid scintillation counter. From the obtained data, the concentration of the compound of the present invention (IC50 value) needed to inhibit the specific binding amount of [3H]PK11195 by 50% was calculated. An inhibition constant (Ki value) was calculated using a KD value and an IC50 value according to the formula of Cheng and Prusoff (Biochem. Pharmacol. 1973; 22: pp. 3099-3108).
  • As a result, it was revealed that the compound of the present invention had high affinity to MBR.

    • Biological Example 2 Study on Antistress Effect (1)
  • Psychological stressor was loaded using a Wistar male rat (Brain Res. 1994; 641: pp. 21-28). Water was accumulated by the depth of about 10 cm in a container having a platform in the center. Thirty-minutes after a medium or the compound of the present invention (the compound of Example 38) was intravenously administered at a dose of 0.01 mg/kg or orally administered at a dose of 1 mg/kg, stressor loading was initiated, and one hour later, the number of dejection was counted (10 animals in each group). The rat administered the compound of the present invention and the rat to which the stressor was not loaded had little dejection after one hour. On the other hand, it was revealed that the medium treatment group to which the stressor was loaded showed remarkable dejection (the number of dejection: mean number 10.5 by intravenous administration, and mean number 8.5 by oral administration), while the compound of the present invention significantly inhibited the number of dejection than the medium treatment group (the number of dejection: mean number 8.2 by intravenous administration and mean number 6.2 by oral administration).
  • As a result, it was found that the compound of the present invention had an antistress effect.
    • Biological Example 3 Study on Antistress Effect (2)
  • Physical stressor was loaded using a male Sprague-Dawley (SD) rat (CHARLES RIVER LABORATORIES JAPAN, INC., 7 week old at being used) (Gastroenterology 1988; 94: pp. 611-622; Jpn. J. Phrmacol. 1998; 77: pp. 211-217). Thirty minutes after a medium (0.5% Tween 80 physiological saline) or the compound of the present invention (the compound of Example 38) was orally administered at a dose of 1 mg/kg, stressor loading was initiated by restraining both anterior branches of the rat with a binding band (Marvel Ltd.). Evaluation was performed by measuring the number of dejection 30 and 60 minutes after the initiation of stressor loading (15 animals in each group). It was revealed that the medium treatment group loaded the stressor showed remarkable dejection (the number of dejection: mean number 10.1 (60 minutes after)), while the compound of the present invention significantly inhibited the number of dejection than the medium treatment group (the number of dejection: mean number 7.5 (60 minutes after)).
  • As a result, it was found that the compound of the present invention had an antistress effect.
    • Biological Example 4 Oral Absorbability of Rat
  • Using a fasted SD male rat (CHARLES RIVER LABORATORIES JAPAN, INC.), under the condition that the compound of the present invention (the compound of Example 38) was solubilized, the plasma concentration after administration in the tail vein at a dose of 0.1 mg/kg and the plasma concentration after gastric gavage administration at a dose of 1 mg/kg were measured. The blood was collected from a rat jugular vein under an unanesthetized condition 5, 15, and 30 minutes, and 1, 2, 3, 4, 6, and 8 hours after intravenous administration, and 15 and 30 minutes, and 1, 2, 3, 4, 6, and 8 hours after oral administration. Then the blood was centrifuged at 3000 rpm for 10 minutes and the supernatant was collected as plasma. The concentration of the compound in plasma was measured with LC/MS/MS (1100 HPLC System (Agilent Co. Ltd.), API 4000 (MDS SCIEX Ltd.)). From the obtained plasma concentration, an area under the curve (AUC, ng·h/ml) and a maximum plasma concentration (Cmax, ng/mL) were calculated. In addition, Bioavailability (B.A.) of the compound of the present invention was calculated from AUC in oral administration and AUC in intravenous administration.
  • As a result, it was found that the compound of the present invention showed B.A. of 86.9% and is excellent in oral absorbability.
    • Biological Example 5 Competition Experiment of MBR Ligand
  • Using a Wistar male rat, psychological stressor similar to that in Biological Example 2 described above was loaded. Each treatment group was set as follows: a medium was intravenously administered (treatment group 1), the compound of the present invention (the compound of Example 38) was intravenously administered at a dose of 0.1 mg/kg (treatment group 2), an MBR selective agonist (CB34) was intravenously administered at a dose of 1 mg/kg (treatment group 3), or after the compound of the present invention (the compound of Example 38) was intravenously administered at a dose of 0.1 mg/kg, an MBR selective agonist was intravenously administered at a dose of 0.1 mg/kg (treatment group 4). In each group, stressor loading was initiated 10 minutes after administration, and the number of dejection was counted one hour later (10 animals in each group). The rats in the treatment groups 1, 3, and 4 showed remarkable dejection (the number of dejection: treatment group 1 (mean number 10.9), treatment group 3 (mean number 9.5), treatment group 4 (mean number 10.1)), while the number of dejection was inhibited in the rat in the treatment group 2 (the number of dejection: mean number 7.3). From this result, it was revealed that the effect observed in single administration of the compound of the present invention was reduced by administration of the MBR selective agonist.
  • As a result, it was speculated that the compound of the present invention expressed an antistress effect since it had an MBR antagonism.
    • Biological Example 6 Study on Inhibitory Action on Abdominal Pain in RCS Loading Model
  • A Wistar male rat (6 week old at being received) was anesthetized with pentobarbital sodium (Kyoritsu Seiyaku Corporation), its abdomen was incised and the abdominal muscle was exposed, and then Force Transducer (F-12IS-SL (STAR MEDICAL Ltd.)) was fitted. Penicillin was intramuscular administered after the operation, and a recuperative period of 5 days was set.
  • During from AM 9:00 to PM 5:00 on a 1st day of the initiation of stress loading, the feeding environment temperature was alternately changed to 24° C. and 2° C. in an hour interval, and during from PM 5:00 to AM 9:00 in the next morning, the rat was fed under the environment of 2° C. From a 2nd day to a 4th day, during AM 9:00 to PM 6:00, the feeding environment temperature was alternately changed to 24° C. and 2° C. in an hour interval, and during PM 6:00 to AM 9:00 in the next morning, the rat was fed under the environment of 2° C. and Repeated cold stress (RCS) was loaded. A medium or the compound of the present invention (the compound of Example 38) was orally administered twice a day at a dose of 1 mg/kg. For the animal to which RCS was not loaded (nonstress loaded rat), a medium was administered.
  • After RCS was loaded for 4 days, abdominal pain evaluation was performed on a 5th day (10 to 12 animals in each group). At evaluating abdominal pain, the stress loaded rat and the nonstress loaded rat received only an indwelling operation were put in a measuring cage, and a balloon (Fogarty catheter 6F (Baxter Ltd.)) was inserted by about 3 cm into the rectum from the anus and fixed. After confirming that abdominal exercise was stable, the liquid amount in the balloon was stepwisely increased to 0, 0.3, 0.6, 0.9, and 1.2 mL in 5 minutes interval. Contraction of abdominal muscle for extension stimulation in each balloon liquid amount was recorded using the Chart software (Chart v5.0.2. (ADInstruments Inc.)) by passing the signal from the pressure transducer amplified by the amplifier (Windo Gragf (GOULD Inc.)) through the data collection system (PowerLab (ADInstruments Inc.)). During 5 minutes in which balloon extension stimulation was loaded, the number of signals from the pressure transducer in 3 minutes was counted, and the obtained number was regarded as the number of abdominal muscle contraction and set as the index of abdominal pain. As shown in FIG. 1, for the number of abdominal muscle contraction increased as compared to the nonstress loaded rat in the medium treatment group, the compound of the present invention significantly inhibited the number of abdominal muscle contraction in all balloon capacities.
  • As a result, it was found that the compound of the present invention had an inhibitory action on abdominal pain induced by stress.
