化合物が下記の表からは選択されない式(I)によって表される化合物またはその化合物の製薬上許容される塩に関するものである。
本発明の化合物を、下記のアッセイで調べた。
T250フラスコで培養したA710(α1b、α2δ、β3を共発現するHEK293)を回収し、緩衝液A(20mM HEPES、10mM EDTA pH=7.4)で1回洗浄した。ペレットを、ポリトロン(Polytron)を用いて緩衝液A中で20秒間均質化した。10分間遠心後、得られたペレットを、同じ緩衝液で1回、緩衝液B(20mM HEPES、0.1mM EDTA pH=7.4)で2回洗浄した。最終的に得られたペレットを同じ緩衝液に再懸濁させ、小分けし、−70℃で保存した。標準としてウシ血清アルブミンを用いるバイオラッド(Biorad)DC法によって、タンパク質含有量を測定した。
解凍後、膜を緩衝液C(50mM TRIS pH=7.1)で1回洗浄し、氷冷アッセイ緩衝液(20mM HEPES pH=7.4)に再度懸濁させて、最終タンパク質濃度をタンパク質50μg/ウェルとした。競争結合実験のため、被験化合物の非存在下または少なくとも11種類の濃度でのその化合物の存在下に、膜を室温で1時間にわたり、7nM[3H]−GABAペンチンとともにインキュベートした。100μM GABAペンチンの存在下に、非特異的結合を測定した。インキュベーション終了後、懸濁液を96ウェルワットマン(Whatmann)GF/Bフィルタープレート(Packard)上で濾過し、氷冷アッセイ緩衝液で3回洗浄した。プレートを乾燥させ、マイクロシンチ(microscint)20(Packard)を50μLずつ各ウェルに加えた。プレートを密封し、パッカード・トップカウントを用いてカウントした。プレートを通常のcpmカウントモードでカウントし(2分間)、一定クエンチング補正によってDPMに変換した。
神経障害性疼痛の脊髄神経結紮モデルを用いて、神経損傷誘発触覚異痛に対する被験化合物の効果を評価した(S. H. Kim and J. M. Chung, Pain 50: 355-363 (1992))。雄スプレーグ・ドーリーラット(175〜200g)に、4−0絹縫合糸を用いて、後根神経節に対して遠位の左L5/L6脊髄神経の片側強圧結紮を施した。脊髄神経結紮以降7〜14日間に、ラットをワイヤメッシュ上のチャンバに入れることで、行動侵害受容試験を行った。ラットについて、神経損傷の部位と同じ側の左後足の足底面に、一連の較正フォン・フレー(von Frey)フィラメントを当てることで、触覚異痛を調べた(非不快点状刺激までの後足引き込み閾値低下)。平均50%後足引き込み閾値(g.)を、ディクソン(Dixon)「上下(up-down)」ノンパラメトリック試験を用いて求めた(Chaplan et al., J. Neurosci. Methods, 53: 55-63 (1994))。薬剤投与前引き込み閾値>4gを示したラットは、異痛性ではないと見なし、本試験から除外した。薬剤投与前引き込み閾値を測定した後、ラットに腹腔内または経口注射で被験化合物を投与した。注射から30、60、90、120分後に後足引き込み閾値を測定することによって、触覚異痛に対する被験化合物の効果を経時的に測定した。上記のモデルにおいて、実施例1は30mg/kgで腹腔内投与した後に65%の効果を生じ、 実施例50は20mg/kgで腹腔内投与した後に100%の効果を生じ、実施例115は30mg/kgで腹腔内投与した後に60%の効果を生じた。
本発明の化合物は、以下の方法に従って製造することができる。置換基は、別段の定義がある場合を除き、式Iの場合と同じである。
