次に、本発明のグリチルレチン酸誘導体の代表的な製造方法について説明する。
本発明の医薬組成物は、有効成分として本発明のグリチルレチン酸誘導体を含有している。本発明のグリチルレチン酸誘導体は、一般的に用いられている種々の処方を適用して各種の製剤形態をとる医薬組成物として提供される。本発明の医薬組成物は、典型的には、本発明のグリチルレチン酸誘導体、またはその薬学的に許容される塩から選択される1種若しくはそれ以上を有効成分として含有することができ、また薬学的に許容される担体をさらに含むことができる。また、通常製剤化に用いられる担体や賦形剤、その他の添加剤を用いて、錠剤、散剤、細粒剤、顆粒剤、カプセル剤、丸剤、液剤、注射剤、坐剤、軟膏、貼付剤等に調製され、経口的(舌下投与を含む)な方法、または皮下注射および腹腔内注射を含む非経口的な方法により投与される。
本発明者らは、本願発明に係るグリチルレチン酸誘導体とは異なるグリチルレチン酸誘導体の合成にも成功している(特許第4649549号)。当該特許発明に係るグリチルレチン酸誘導体(当該特許における「化合物B」、以下「化合物B」と称する)は、本願発明に係るグリチルレチン酸誘導体と同様に、ギャップ結合を阻害することにより活性化ミクログリアからのグルタミン酸放出を抑制し、また神経細胞死を抑制し、そして種々の神経疾患の治療剤となり得るものである。
式(2)の化合物において、X-がヨウ素イオン(I-)である本発明のグリチルレチン酸誘導体(以下、TypeC-05ともいう)を以下のスキームで合成した。
水(260mL)に濃塩酸(104mL)を加え、氷冷下でTiCl3(22%)を376mL加えた。アルゴンガスをバブリングして撹枠しながら酢酸ナトリウム(215g)を加え、水(160mL)で希釈した。
C57BL/6Jマウス(8週齢オス,各群n=4)の後肢に、慢性坐骨神経損傷手術(CCI)を施し、慢性痛を引き起こした。マウスの後肢足蹠にvon Frey hairを押し当て、回避行動を示す機械強度の閾値を記録した(CCI術前日~術後14日)。
コントロール:同容量生理食塩水
Gabapentin:30mg/kg 腹腔内投与
化合物No.37:100mg/kg 皮下投与
化合物No.37:20mg/kg 皮下投与
化合物No.37:20mg/kg 腹腔内投与
図3に示すように、術後8日目の観測から各試験群に相違が生じ始め、化合物No.37を100mg/kgで皮下投与した群および化合物No.37を20mg/kgで腹腔内投与した群においては、Gabapentinと比較して顕著に疼痛閾値の上昇が見られた。特に腹腔内投与ではGabapentinよりも低い濃度において疼痛閾値の上昇が見られている。
CCI術後14日目に上述のマウスの大後頭孔から脳脊髄液を採取し、グルタミン酸濃度をHPLCで定量測定した。
本願発明に係るグリチルレチン酸誘導体(上記式(2)の化合物)とカルベノキソロンとのLD50(50%致死量)を比較した。その結果、カルベノキソロンが100mg/kgであったのに対して、本願発明に係るグリチルレチン酸誘導体では>5000mg/kgを示した(図示せず)。このことから、本願発明に係るグリチルレチン酸誘導体はカルベノキソロンに比べて最大耐量が高く、安全性の観点からみても従来のギャップ結合阻害剤よりも優れていることがわかる。
神経変性疾患に対する動物モデルとして、筋萎縮性側索硬化症(ALS)の急性発症モデルとして汎用されている、ヒトスーパーオキシドジスムターゼ1(superoxide dismutase 1,SOD1)G93A変異トランスジェニックマウスを用いて、薬効評価を行った。
次に、神経変性疾患に対する動物モデルとして、アルツハイマー病モデルとして汎用されている、ヒトアミロイドβ1-42ペプチド(Aβ)脳室内注入マウス(Doi et al.,Am J Pathol.175(5):2121-32,2009)を用いて、本願発明のグリチルレチン酸誘導体(化合物No.37群)の薬効評価を行った。
連合学習は恐怖条件付け学習試験を用いて評価した(Mouri et al.,FASEB J.21,2135-2148,2007;Nagai et al.,FASEB J.17,50-52,2003)。マウスをステンレス製グリッドを設置した透明のアクリル製ケージに入れ、20秒間の音刺激(80dB)を与え、さらに、その最後の5秒間に電気刺激(0.6mA)を加えた。この組み合わせ刺激を1セットとし、15秒間のインターバルで4回繰り返し、恐怖条件付けを行った。状況依存性試験および音刺激依存性試験は、恐怖条件付けの24時間後に行った。前者では、恐怖条件付けを行ったグリッド付アクリル製白色ケージへマウスを入れ、音および電気刺激を与えない状況下でのすくみ行動を2分間測定した。また、後者では、床にウッドチップを敷いたアクリル製黒色ケージにマウスを入れ、連続した音刺激を与えたときのすくみ行動を1分間測定した。結果はそれぞれ、全測定時間に対するすくみ行動時間の百分率(%)として表した。結果を図6に示す。
