Definitions
- the present invention relates to a novel biphenylacetamide derivative useful as a therapeutic agent for epilepsy.
- Epilepsy is a chronic disease in which paroxysmal movement, consciousness, sensory abnormalities, and behavioral abnormalities resulting from excessive excitation of cranial nerve cells are repeated. And one in three cases of this disease is refractory epilepsy that shows resistance to existing drug treatments.
- Epilepsy seizures are broadly classified into partial seizures and generalized seizures. Partial seizures indicate behavioral abnormalities and electroencephalographic abnormalities that start in a limited area of the unilateral cerebral hemisphere. Partial seizures are further classified into simple partial seizures, complex partial seizures, and secondary generalized tonic-clonic seizures.
- generalized seizures are seizures that do not show a localized seizure origin and manifest symptoms in bilateral hemispheric synchronization. The usual clinical symptoms of generalized seizures are characteristic systemic motor symptoms with loss of consciousness.
- the electroencephalogram at the time of seizure is bilaterally synchronized. Absence attack (Absence ⁇ seizure), atypical absence attack (Atypical absence seizure), myoclonic attack (Myoclonic seizure), tonic seizure (Clonic seizure), clonic seizure, tonic-clonic seizure ), Weakness attacks (Atonic ⁇ ⁇ ⁇ seizure), West syndrome (West syndrome) and Lennox-Gastaut syndrome are classified as generalized seizures.
- antiepileptic drugs have no specific mechanism of action, and various mechanisms are considered to act in a complex manner. Therefore, some of the drugs that have been developed as antiepileptic drugs so far have been widely used in multiple neurological and mental disorders (Pawel, DZ et al., Non-epilepsy use of antiepileptic drugs, Pharmacological Reports, 2006, 58, 1-12).
- bipolar disorder manic-depressive disorder
- mood modulation has few specific treatments (lithium only)
- some antiepileptic drugs have a mood-stable effect (mood stabilizer) is recognized and used.
- Valproic acid has been used.
- valproic acid has been used in clinical practice as well as lithium (Angel, I and Horovitz, T., Bipolar disorder and valproic acid) as a first-line drug for bipolar depression.

Lock and make 1000 tablets.
- Formulation Example 2 Preparation of powder After mixing the compound of Example 1 (500 g), lactose (470 g), hydroxypropylcellulose (25 g) and light anhydrous silicic acid (5 g), a powder is prepared.
- the biphenylacetamide derivative of the present invention has a maximum electric shock convulsion model (MES) evaluation, a subcutaneous injection pentetrazole model (minimum convulsion model, scPTZ) evaluation, and a 6 Hz spirit. Strong anticonvulsant activity in all motor seizure model evaluation and / or rat amygdala kindling model evaluation.

- the compounds of the present invention are antiepileptic drugs (e.g., partial seizures including simple partial seizures, complex partial seizures and persistent secondary generalized seizures with loss of consciousness, absence seizures, myoclonic seizures, clonic seizures, It is useful as a prophylactic and / or therapeutic drug for generalized seizures such as tonic seizures, tonic-clonic seizures, weakness seizures, West syndrome and Lennox-Gastaut syndrome.
- these group of compounds of the present invention are also expected as preventive and / or therapeutic agents for intractable epileptic seizures for which pharmacotherapy is not yet effective.

以下に、本発明の代表的化合物の薬理試験結果を示し、該化合物についての薬理作用を説明するが、本発明はこれらの試験例に限定されるものではない。
また、双極性障害への改善効果を評価するに際し臨床予測性の高い妥当な動物モデルは未だ報告されていないが、本疾患の背景にある「躁状態」、「うつ状態」それぞれの病態を捉えた動物モデルは幾つか報告されており、それぞれの代表的モデルとしてメタンフェタミンとクロルジアゼポキシドを併用投与した際に認められる過剰な運動亢進状態(躁状態)、強制水泳時に見られる無動状態(うつ状態)を指標にした改善評価が一般的に用いられている。これら両モデルに対し改善活性を示す化合物は本病態の躁うつ分裂的な気分変動を安定化させる効果として期待できる。
本試験は、薬物の抗痙攣作用を評価する試験である。この試験で用いる動物モデルは、全般性強直間代発作や二次性全般化部分発作の表現系である。Slc:ddY系雄性マウス(一群3匹、体重20~30g)に被験化合物50及び100 mg/kgを経口投与し、1時間後に角膜より電気刺激(60Hz,25mA,0.2秒間)を与え、誘発される後肢の強直性伸展痙攣の発現抑制を観察した。なお、コントロールは0.5%トラガント液あるいは0.5%メチルセルロース液を投与した。結果を以下の表19に示す。
本試験は、試験例1と同様に薬物の抗痙攣作用を評価する試験である。この試験で用いる動物モデルは、試験例1の表現系とは異なり、全般性の欠神発作やミオクロニー発作の表現系である。Slc:ddY系雄性マウス(一群3匹、体重20~30g)に被験化合物50及び100 mg/kgを経口投与し、1時間後にペンテトラゾール85 mg/kgを皮下投与した。その後、30分間における間代性痙攣の発現の有無を観察した。なお、コントロールは0.5%トラガント液あるいは0.5%メチルセルロース液を投与した。結果を以下の表23に示す。
本試験は、マウスに加え、ラットにおける薬物の抗痙攣作用を評価する試験である。この試験で用いる動物モデル(キンドリングモデル)は、焦点性の単純部分発作、複雑部分発作及び二次性全般化部分発作の臨床所見に類似するモデルであり、極めて臨床予測性が高いことが知られている。Slc:Wistar系雄性ラット(体重250~300g)の大脳皮質(前、後)ならびに扁桃核に慢性電極を留置し、術後1週間目より扁桃核へ1日1回、2週間前後にわたり電気刺激(50Hz,400μA,1秒)を与えた。刺激条件は、Loscherらの方法[Epilepsy Res., 40:63-77(2000)]に従った。また、Racineらの方法[Motor seizure. Electroenceph. Clin. Neurophysiol., 32:281-294(1972)]に基づいた発作重症度においてstage5の発作が連続10回発現するまで刺激を継続し、キンドリングモデルを完成させた。完成したモデルに、試験化合物を各々100mg/kgで経口投与し、投与1時間後に、発作が誘発される閾値刺激電流(発作閾値)、脳波上に認められる後発射の持続時間(後発射時間)及び発作重症度(stage score 1~5)を指標に評価した。発作閾値ならびに後発射時間は試験化合物投与前の各値に対する変化率を平均で表した。なお、コントロールは0.5%トラガント液を投与した。結果を表24に示す。マイナスは減少あるいは短縮を意味する。
本試験は、試験例1ならびに試験例2と同様に薬物の抗痙攣作用を評価する試験である。この試験で用いる動物モデルは、試験例1ならびに試験例2とは異なり、既存の抗てんかん薬に治療抵抗性を示す発作の表現系である。Slc:ddy系雄性マウス(一群5匹、体重20~30g)に被験化合物100 mg/kgを経口投与し、30分あるいは1時間後に角膜より電気刺激(6Hz,32mA,3秒間)を与え、誘発される前肢の間代性痙攣、挙尾反応、無動状態の発現の有無を観察した。なお、コントロールは0.5%トラガント液、0.5%メチルセルロース液、或いは、Olive oilを投与した。結果を表25に示す。
本試験は、薬物の協調運動能抑制作用を評価する試験である。Slc:ddy系雄性マウス(体重20~30g)を試験前日にローターロッド装置(直径4cmの円柱棒を回転させる装置、13回転/分)で3分間落下しないで歩行できるように訓練する。一群10匹に被験化合物を経口投与し、1時間後に上記同様にローターロッド装置に乗せ、100秒間歩行状態を観察した。100秒以内に協調運動障害にて落下した動物を陽性としてカウントした。なお、コントロールは0.5%メチルセルロース液を投与した。結果を表26に示す。
本試験は、薬物の抗うつ作用を評価する代表的な試験である(Porsoltら、Nature,266:730-732、1977,Porsolt ら、 Eur . J. Pharmacol .,47 : 379- 391 、 1978)。Crl:CD(SD)系雄性ラット(1群12匹、体重200~250g)を後肢が底面に接触できない深さ(205 mm)まで水を溜めた直径200 mmの水槽で15分間強制的に水泳を行わせ、水泳終了15分後に被験化合物を経口投与した。翌日、同用量の被験化合物を投与し、前日と同時刻に5分間水槽に移して、水泳行動を行わない無動時間を測定した。コントロール群に対する無動時間の短縮度合いにより抗うつ作用を評価した。コントロール群は0.5%メチルセルロース液を投与した。なお、上記条件において双極性障害に適応を持つLamotrigineは用量依存的に無動時間を短縮した。結果を表27に示す。
本試験は、薬物の抗躁作用を評価する試験である。本評価系は、統合失調症治療薬とは異なる気分安定化薬として臨床で使用されている抗躁病薬で有効性が確認できる試験系である(Arbanら、Behav. Brain Res.,158:123-132、2005、Foreman ら、 Pharmacol. Biochem. Behav. ,89 : 523-534 、 2008)。Slc:C57BL/6J 系雄性マウス(1群8匹、体重20~26g)に被験化合物を経口投与し、30分後にメタンフェタミン(4mg/kg)及びクロルジアゼポキシド(10mg/kg)を腹腔内投与した。その後90分間アクリル製ケージ(内寸:W360mm×D230mm×H310mm)の中で自由行動させ、動物の移動距離をEthovision software(Ver.3.1)を用いて測定した。新規環境馴化時間30分を除いた後半60分間の移動距離を測定値として用いた。コントロール群に対する短縮度合いにより抗躁作用を評価した。なおコントロール群は0.5%メチルセルロース液を投与した。なお、上記条件において、双極性障害に臨床適応を持つLamotrigineは用量依存的に移動距離を短縮した。結果を表28に示す。
