明 細 書 鎮 痛 剤 技術分野  Description Pain Relief Technical Field
本発明は医薬の発明に関するものであり、 より詳しく言うと、 ピぺリジン誘導 体又はその薬理学的に許容される塩を有効成分として含む鎮痛剤に関するもので ある。 背景技術  The present invention relates to a pharmaceutical invention, and more particularly, to an analgesic containing a piperidine derivative or a pharmacologically acceptable salt thereof as an active ingredient. Background art
急性痛は組織損傷の可能性を持つ剌激による痛みであり、 骨折や切傷など受傷 による痛み、虫垂炎などの炎症性の痛み、及び術後痛などが急性痛に分類される。 急性痛の治療には、 主としてモルヒネなどの麻薬性鎮痛薬、 非ステロイ ド系抗炎 症薬 (NSAIDs)、又は局所麻酔薬が用いられている。急性痛が長期に持続すると、 痛覚伝導系の正常機能が障害され、 慢性疼痛の原因となる場合があるので、 より 優れた鎮痛効果を発揮できる薬剤の開発が望まれている。  Acute pain is pain due to irritation, which may cause tissue damage. Pain due to injury such as a fracture or cut, inflammatory pain such as appendicitis, and postoperative pain are classified as acute pain. For the treatment of acute pain, narcotic analgesics such as morphine, non-steroid anti-inflammatory drugs (NSAIDs), or local anesthetics are mainly used. If acute pain persists for a long period of time, the normal function of the pain sensory system may be impaired, which may cause chronic pain. Therefore, it is desired to develop a drug that can exert a superior analgesic effect.
また、 神経因性疼痛は末梢神経系または中枢神経系の損傷、 機能障害などが原 因となって生じる痛みであり、 モルヒネなどのオビオイ ド系薬物でさえも十分に 奏効しないことから、 難治性疼痛ともいわれる。 神経因性疼痛を伴う疾患として は、 例えば帯状疱疹後神経痛、 三叉神経痛、 糖尿病性神経症、 術後や外傷後の遷 延痛など、 痛覚過敏ゃァロディニァの症状を呈する疾患を挙げることができる。 現在、 神経因性疼痛に対する薬物療法として、 消炎鎮痛薬やオビオイ ドなどの鎮 痛剤に加えて、 抗うつ薬、 抗てんかん薬、 抗不整脈薬、 GABA作動薬などの鎮痛 補助薬を併用する方法が採用されている。 しかしながら、 神経因性疼痛に対する 有効な治療法は未だ確立されているとはいえないのが現状である。  Neuropathic pain is caused by damage to the peripheral nervous system or central nervous system, dysfunction, etc., and even intractable drugs such as morphine and other obioids do not respond sufficiently. Also called pain. Diseases associated with neuropathic pain include, for example, diseases exhibiting hyperalgesia parodynia, such as postherpetic neuralgia, trigeminal neuralgia, diabetic neuropathy, and prolonged pain after surgery or trauma. At present, pharmacotherapy for neuropathic pain is a combination of analgesics such as anti-inflammatory analgesics and obioids, and adjuvant analgesics such as antidepressants, antiepileptics, antiarrhythmics, and GABAergic drugs. Has been adopted. However, effective treatments for neuropathic pain have not yet been established.

試験例 1 :式 ( I ) の化合物の鎮痛作用 Test Example 1: Analgesic effect of compound of formula (I)
ホルマリンテストにより本発明の医薬の鎮痛作用を検討した。 ホルマリンテス トは炎症性疼痛モデルの一つであり、 鎮痛作用の検討に広く用いられている。 ホ ルマリンをラットに皮下投与すると二相性の痛み行動を示す。 第 1相 (ホルマリ ン投与後 9分まで) は局所神経の直接刺激による急性痛、 第 2相 (ホルマリン投 与後 10〜60 分) は第 1相の痛み刺激と炎症反応による持続的疼痛刺激により誘 導される痛覚過敏と考えられている (ペインクリニック、 1 5卷、 4 9 8— 5 0 2頁、 1 9 9 4年)。  The analgesic effect of the medicament of the present invention was examined by a formalin test. Formalin test is one of the inflammatory pain models, and is widely used to study analgesic effects. Subcutaneous administration of formalin to rats shows biphasic pain behavior. Phase 1 (up to 9 minutes after formalin administration) is acute pain due to direct stimulation of local nerves, Phase 2 (10-60 minutes after formalin administration) is phase 1 pain stimulation and continuous pain stimulation due to inflammatory response (Pain Clinic, Vol. 15, pp. 498—502, pp. 199-4).
( 1 )動物およびカテーテル装着手術  (1) Animal and catheter mounting surgery
SD系雄性ラット (体重 290〜310g、 セアツク吉富) を用い、 ハロタン (フロー セン、 武田薬品工業株式会社製) 麻酔下で Yakshand Rudyの方法 (フイジォロジ カル · ビヘイビア一 (Physiol . Behav. ), 1 7卷、 1 0 3 1— 1 0 3 6頁、 1 9 7 6年) に準じて、 大槽より脊髄クモ膜下腔にポリエチレン製カテーテル(PE10、 べクトンディッキンソンアンドカンパニー) を挿入して留置した。体重減少(10 以上)、 脊髄傷害や強いストレス症状の認められるものは実験から除外し、 手術 後 3〜7曰に実験を行った。  Using male SD rats (body weight: 290-310 g, Yoshitsumi SEATUK) and anesthesia with halothane (Flosen, manufactured by Takeda Pharmaceutical Co., Ltd.), Yakshand Rudy's method (Physiol. Behav.), 17 Vol., 10 3 1—10 36, 1976), a polyethylene catheter (PE10, Becton Dickinson and Company) was inserted into the spinal subarachnoid space from the cisternal and placed there. . Those with weight loss (10 or more), spinal cord injury or severe stress symptoms were excluded from the experiment, and the experiment was performed 3 to 7 after the operation.
(2)薬液調製 試験化合物の投与用量は 10 gで検討した。 投与薬液は、 化合物 6 6および化 合物 1 3 2については、 ジメチルスルホキシド (DMS0、 ナカライテスク株式会社 製) で溶解し、 lmol/L 塩酸 (和光純薬工業株式会社製) を加えて酸性化した後 に生理食塩水(大塚生食注、株式会社大塚製薬工場製)で希釈した(DMS0 : lmol/L 塩酸:生理食塩水 =30: 3 : 67)。 化合物 1 2および化合物 1 3 3については蒸 留水 (大塚蒸留水、 株式会社大塚製薬工場製) で溶解した。 対照群にはそれそれ の溶媒を投与した。 薬液投与容量は 1匹あたり 10 Lとし、 投与用量が 10 /gと なるように lmg/mL の溶液を調製した。 ホルマリンは、 ホルムアルデヒド液 (特 級、 36%、 関東化学株式会社製) を蒸留水 (大塚蒸留水、 株式会社大塚製薬工場 製) で希釈して 5%とした。 (2) Chemical solution preparation The administration dose of the test compound was 10 g. The administered drug solution was prepared by dissolving Compound 66 and Compound 132 with dimethyl sulfoxide (DMS0, manufactured by Nacalai Tesque, Inc.) and adding lmol / L hydrochloric acid (manufactured by Wako Pure Chemical Industries, Ltd.) to acidify. After that, the mixture was diluted with saline (Otsuka Ishoku Injection, manufactured by Otsuka Pharmaceutical Factory Co., Ltd.) (DMS: lmol / L hydrochloric acid: saline = 30: 3: 67). Compounds 12 and 13 were dissolved in distilled water (Otsuka distilled water, manufactured by Otsuka Pharmaceutical Factory Co., Ltd.). Control groups received their respective solvents. The volume of drug solution administered was 10 L per animal, and a lmg / mL solution was prepared so that the dose would be 10 / g. Formalin was prepared by diluting formaldehyde solution (special grade, 36%, manufactured by Kanto Chemical Co., Ltd.) with distilled water (Otsuka Distilled Water, manufactured by Otsuka Pharmaceutical Factory Co., Ltd.) to 5%.
( 3 )薬理作用の検討  (3) Pharmacological studies
実験は 1群 5匹で行った。 上記(1 )の方法でカテーテルを留置した動物をボー ルマンケージで保定し、 ホルマリン投与 10分前にカテーテルから薬液 10 /L を 脊髄クモ膜下腔投与( i . t . )した後、 続けてカテーテルのフラッシュのために生理 食塩水 (大塚生食注、 株式会社大塚製薬工場製) 10/ Lを投与した。 対照群には、 同様の方法で溶媒又は蒸留水を投与した。 その後、 両側後肢をケージから出して 運動を妨げない状態にし、 30G 注射針 (眼内注射針、 二プロ医ェ株式会社製) を 用いて左後肢背側に 5%ホルマリン 50 L を皮下投与した。 ホルマリン投与 1分 後から、 処置足を振る動作 (flinching 回数/分) を測定し、 痛み反応の指標と した。 測定は、 ホルマリン投与後 1分から 6分までは 1分毎に、 10分より 60分 までは 5分毎にそれそれ行った。 測定前および測定中に強いストレス症状が認め られた場合には実験を中止した。  The experiment was performed with 5 animals per group. The animal in which the catheter was indwelled by the method (1) above was kept in a Bollman cage, and 10 minutes before the administration of formalin, 10 / L of the drug solution was intrathecally administered (i.t.) from the catheter to the spinal cord. For flushing the catheter, 10 / L of physiological saline (Otsuka Raw Food Infusion, manufactured by Otsuka Pharmaceutical Factory Co., Ltd.) was administered. The control group received a solvent or distilled water in the same manner. Then, both hind limbs were taken out of the cage so as not to hinder the movement, and 50 L of 5% formalin was subcutaneously administered to the dorsal side of the left hind limb using a 30G injection needle (intraocular injection needle, manufactured by Nipro Medical Co., Ltd.). . One minute after the administration of formalin, the movement of shaking the foot (flinching frequency / min) was measured and used as an index of pain response. Measurements were taken every minute from 1 to 6 minutes after formalin administration and every 5 minutes from 10 to 60 minutes. The experiment was stopped if severe stress symptoms were observed before and during the measurement.
(4)データ処理  (4) Data processing
Flinching回数の経時的変化についての測定結果は、平均土標準誤差で表した。 統計解析は SASを用いて行った。 分散に差がない場合は Student' s t-test を用 い、 分散に差がある場合は Aspin-Welchtestを用いて Pく 0.05 を有意とした。 対 照群と試験化合物投与群について、 投与後 10分までを第 1相、 10分から 60分 までを第 2相として、 それそれの flinching回数の合計を比較し、 有意な低下が 認められた場合に鎮痛作用ありと判定した。 また、 下記の計算式:抑制率(50 = 1- 〔(薬物投与群 flinching回数) / (対照群 flinching回数)〕 x 100に従 つて抑制率を算出した。 結果を第 1 1表に示す。 化合物 66、 化合物 132、 及 び化合物 133は第 1相及び第 2相のいずれに対しても鎮痛作用を示した。また、 化合物 12は第 2相において優れた疼痛抑制作用を示した。 The measurement results for the change over time of the number of times of flinching were represented by an average soil standard error. Statistical analysis was performed using SAS. If there was no difference in variance, Student's t-test was used, and if there was a difference in variance, P-0.05 was considered significant using Aspin-Welchtest. Phase 1 in the control group and test compound administration group up to 10 minutes after administration, 10 minutes to 60 minutes As a second phase, the total number of flinching times was compared, and if a significant decrease was observed, it was judged that there was an analgesic effect. The inhibition rate was calculated according to the following formula: inhibition rate (50 = 1-[(number of flinching times in drug administration group) / (number of flinching times in control group))] x 100. The results are shown in Table 11. Compound 66, compound 132, and compound 133 showed analgesic activity in both phase 1 and phase 2. Compound 12 showed excellent pain-suppressing activity in phase 2.
