TECHNICAL FIELD

The present invention relates to a diazepine derivative having a P2X4 receptor antagonist activity.

BACKGROUND ART

The ATP receptors are roughly classified into the P2X family of the ion channel type receptors, and the P2Y family of the G protein coupling type receptors, and seven kinds (P2X1 to P2X7) and eight kinds (P2Y1, P2Y2, P2Y4, P2Y6, and P2Y11 to P2Y14) of subtypes have so far been reported, respectively.

The P2X4 receptor (Genebank No. X87763), a subtype of the P2X family, has been reported to be widely expressed in the central nervous system, and the like (Non-patent documents 1 to 5).

The onset mechanisms of intractable pains, including neuropathic pain, have not been precisely elucidated. If non-steroidal anti-inflammatory drugs (NSAIDs) and morphine are not effective, no therapy is available for that pain. Therefore, very heavy physical and mental burden is given to patients and surrounding people. Neuropathic pain is often caused by injury of a peripheral nerve or the central nerve, and it is caused by, for example, after-trouble of operation, cancer, spinal cord injury, herpes zoster, diabetic neuritis, trigeminal neuralgia, and the like.

Recently, Inoue et al. verified the involvement of the P2X receptor in neuropathic pain by using a spinal nerve-damaged animal model in which allodynia can be detected. The authors described that nerve-damaged type unusual pain (especially allodynia) is induced through the P2X4 receptor expressed in the microglia cells of the spinal cord (Non-patent documents 6 and 7, and Patent document 1).

Therefore, a substance that inhibits the activity of the P2X4 receptor is expected to be a prophylactic or therapeutic agent for pains of nociceptive pain, inflammatory pain, and neuropathic pain.

Patent document 2 reported that a benzofuro-1,4-diazepin-2-one derivative represented by the following general formula (A):

[Image Omitted]

(in the formula, R₁is a halogen, and R₂is hydrogen, a halogen, nitro, cyano, C(O)—OR₃, C(O)—NR₄R₅, SO₂—OR₃, or SO₂—NR₄R₅, or alternatively, R₁is hydrogen, and R₂is a halogen, nitro, cyano, C(O)—OR₃, C(O)—NR₄R₅, SO₂—OR₃, or SO₂—NR₄R₅) has a P2X4 receptor antagonist activity.

It was also reported that paroxetine, which is an antidepressant, also has a P2X4 receptor antagonist activity (Non-patent document 8).

The inventors of the present invention also found that a naphtho[1,2-e]-1,4-diazepin-2-one derivative represented by the following formula (B):

[Image Omitted]

and related compounds thereof has a P2X4 receptor antagonist activity, and filed patent applications (Patent documents 3, 4 and 5).

The compounds of Patent documents 3 to 5 mentioned above and the compounds of the present invention represented by the general formula (I) mentioned later are distinguishable from each other in that, in the former compounds, the substituent of the phenyl group at the 5-position is hydroxy group, a halogen atom, an alkyl group having 1 to 8 carbon atoms, tetrazolyl group, or the like, whereas, in the latter compounds, the phenyl group or the heterocyclic ring represented by G is bound via NHC(═O), NHC(═O)NH, or NHS(O)₂represented by B. In addition, although Patent documents 4 and 5 describe an acylamino group having 2 to 8 carbon atoms and an acylamino group having 2 to 8 carbon atoms and substituted with 1 to 3 halogen atoms as the substituent of the aforementioned phenyl group, they only refer to lower alkylcarbonylamino groups such as acetylamino and trifluoromethylcarbonylamino groups as specific examples thereof, and do not describe benzoylamino group wherein G is phenyl group, and B is NHC(═O) and the like of the compounds of the present invention represented by the general formula (I) mentioned later.

Further, Patent document 6 describes a naphtho[1,2-b]-1,4-diazepin-4-one derivative represented by the following formula (C):

[Image Omitted]

However, although Patent document 6 describes that the compound represented by the aforementioned formula (C) is used as a photographic coupler, there is no description suggesting relation between such a compound and P2X4 receptor antagonist activity.

Further, Patent document 7 describes a 1,4-benzodiazepine derivative having a phosphodiesterase 2 inhibitory activity, which is represented by the formula (D):

[Image Omitted]

However, this patent document does not describe that the compound of the formula (D) has a P2X4 inhibitory activity.

Hereafter, the pharmacological efficacies of the compounds of the present invention will be described.

The P2X4 receptor antagonist activity of the compounds of the present invention was measured as follows.

The ATP receptor (human P2X4) was introduced into the 1321N1 cells, and the cells were used as a stable ATP receptor expression system. The P2X4-expressing 1321N1 cells were inoculated on a 96-well plate, cultured under the conditions of 37° C. and 5% CO₂for 24 hours, and used for calcium measurement. Fura-2 AM, which is a calcium fluorescent indicator, was dissolved in an extracellular fluid for calcium imaging, and the inoculated cells were treated with the solution, and left standing at room temperature for 45 minutes so that Fura-2 AM was incorporated into the cells. For the measurement, a microplate reader, FLUOstar Optima (BMG Labtech), was used. The light emitted from a xenon lamp was passed through 340 nm and 380 nm filters, respectively and irradiated on the cells, fluorescences of 510 nm, F340 and F380, emitted from the cells were measured, and change of the ratio F340/F380 was used as an index of change of intracellular calcium level. The measurement was performed by adding ATP to each well at a final concentration of 1 μM, and observing the ATP-induced Ca²⁺ response over time. In the measurement, a treatment with a test substance was performed 15 minutes before the addition of ATP, and the inhibition activity of the test substance was calculated by comparison of the result with the result obtained in the absence of the test substance.

As clearly seen from the results for the compounds of Examples 215 and 216, the compounds of the present invention showed superior P2X4 receptor antagonist activity (Tables 22 and 23).

As clearly seen from the result for the compound of Example 217, the compound of the present invention showed superior analgesic activity.

Therefore, the diazepine derivatives represented by the aforementioned general formula (I) and (II), and pharmacologically acceptable salts thereof have a P2X4 receptor antagonist activity and accordingly, it is considered that they are useful as prophylactic or therapeutic agents for pains of nociceptive pain, inflammatory pain, and neuropathic pain. More specifically, they are useful as prophylactic and therapeutic agents for pains accompanying various cancers, pains accompanying diabetic nerve damage, pains accompanying viral diseases such as herpes, arthrosis deformans, and the like. The prophylactic or therapeutic agent of the present invention may be used together with other medicaments if needed, and may be used together with, for example, opioid analgesics (morphine, fentanyl), sodium channel blockers (Novocain, lidocaine), NSAIDs (aspirin, ibuprofen), and the like. Further, when it is used for cancerous pain, it may be used together with, for example, anticancer agents such as anticancer chemotherapeutic agents.

The compounds of the present invention can be administered to a human by an appropriate administration method, such as oral administration or parenteral administration.

For manufacturing pharmaceutical preparations containing the compounds of the present invention, dosage forms such as tablets, granules, powders, capsules, suspensions, injections, and suppositories can be prepared by the methods usually used in the field of pharmaceutical manufacturing.

For manufacturing such preparations, in the case of tablets, for example, usual excipients, disintegrating agents, binders, lubricants, dyes, and the like are used. Examples of excipient include lactose, D-mannitol, crystalline cellulose, glucose, and the like, examples of disintegrating agent include starch, carboxymethylcellulose calcium (CMC-Ca), and the like, examples of lubricant include magnesium stearate, talc, and the like, and examples of binder include hydroxypropylcellulose (HPC), gelatin, polyvinylpyrrolidone (PVP), and the like. For manufacturing injection, solvents, stabilizers, dissolving aids, suspending agents, emulsifiers, soothing agents, buffering agents, preservatives, and the like are used.

As for the administration dose, the compounds of the present invention as the active ingredient can usually be administered to an adult in a daily dose of about 0.01 to 100 mg in the case of injection, or a daily dose of 1 to 2000 mg in the case of oral administration, but the dose may be increased or decreased depending on age, symptoms, and the like.

(P2X4 Receptor Antagonist Activity)
(Test Method)

The P2X4 receptor antagonist activity of the compounds of the present invention was measured as follows. The 1321N1 cells stably expressing human P2X4 receptor were inoculated on a 96-well plate, cultured under the conditions of 37° C. and 5% CO₂for 24 hours, and then used for intracellular calcium measurement. Fura-2 AM, which is a calcium fluorescent indicator, was used for the intracellular calcium measurement. Fura-2 AM dissolved in an assay buffer was added to the cells, the cells were left standing at room temperature for 45 minutes so that Fura-2 AM was incorporated into the cells, and then the plate was subjected to the fluorescence measurement. The treatment of the cells with each test substance was performed 15 minutes before the addition of ATP, and inflow of calcium into the cells as a response induced by the addition of ATP was measured over time by using a microplate reader. The ratio of fluorescence values obtained with excitation lights of 340 nm and 380 nm was used as an index of the change of intracellular calcium level, and the inhibition activity of the test substance was calculated on the basis of the comparison with the value obtained in the absence of the test substance (control).

(Analgesic Activity)

The analgesic activity of the compounds of the present invention was measured by the following method.

Preparation of Neuropathic Pain Model (Modified Chung Model)

Neurogenic pain model (modified Chung model) was prepared according to the description of Non-patent document 9. More specifically, under isoflurane anesthesia, back hair of rats was extensively shaved, the shaved parts were wiped with rubbing alcohol, the rats were fixed on an incubator in the abdominal position, and the skins were cut and opened along the dorsal median line on the upper and lower sides of the sacroiliac bone. The left lateral paravertebral muscle was separated in the sacral region, and then the ligament was separated. The sacroiliae rim and the upper part thereof were cut and opened along the pyramid, the L5 nerve was ligated, and the nerve was cut on the peripheral side. The operative wound was sutured, and infection was prevented by intraperitoneal injection of Luinesin after the operation.

The pain threshold value (paw withdrawal threshold (g)) was calculated according to the up down method by stimulating the sole with a von Frey filament (Stoelting Co., TOUCH-TEST SENSORY EVALUATOR) and determining presence or absence of withdrawal response. The rats that showed a 50% pain threshold value of 5 g or lower in the von Frey filament test were determined to have allodynia.

Up Down Method and Calculation Method of 50% Threshold Value

As the von Frey filaments, seven filaments giving different stimulation strengths were used. The 50% threshold value was calculated according to the up down method by referring to the method of Chaplan et al. (Chaplan S R, Bach F W, Pogrel J W, Chung J M, Yaksh T L.: Quantitative assessment of tactile allodynia in the rat paw, J. Neurosci. Methods, 53:55-63 (1994).

Evaluation Method and Results

The efficacy was evaluated by orally administering the compounds of Examples 48 and 118 using an oral feeding needle to rats on the day 9 after the modified Chung operation, and observing the influence on the pain threshold value determined by the von Frey filament test. As a result, oral administration of 50 mg/kg of the compounds of Examples 48 and 118 raised the pain threshold value of the diseased limb, and it was observed that there was a significant difference compared with the result for the vehicle group.
