I− 生物学的評価
化合物A1はフリーラジカル捕捉実験を行うために用いた。生物学的な抗酸化剤及び抗フリーラジカル剤として作用するこれらの能力に関して、本発明に従ういくつかの化合物をin vitroで試験した。
フリーラジカル捕捉実験(これは、炭素(CH3及びCO2ラジカル)及び酸素(OHラジカル)を主としており、化合物A1について行われた)は、PBNの官能化がフリーラジカル種を捕捉するこれらの化合物の能力に影響は及ぼさないことを示した。図7に示すように、炭素を中心とするフリーラジカル種に特有のEPRシグナルが観察できた。
a− カスパーゼIII(caspase III)の酵素活性アッセイによるラット皮質ニューロンにおける抗アポトーシス能の評価。
これらの両親媒性ニトロンの保護効果を、過酸化水素で30分間毒素化した後の神経−筋共培養物において評価した。
NARP遺伝子(ミトコンドリア鎖のV複合体のタンパク質(サブユニット6)をコードする)の変異により特徴付けられる線維芽細胞株について試験を行う。これらの細胞は、スーパーオキシドジスムターゼ酵素を異常に過剰生産することを特徴とし、この遺伝的な不足は、スーパーオキシドフリーラジカル生産の増加を引き起こすことを示唆する。このスーパーオキシドフリーラジカルの過剰生産は、細胞のアポトーシスが加速されるプロセス引き起こす(Geromel V., Kadhom N., Cebalos-Picot I., Ouari O., Polidori A., Munnich A., Rotig A., Rustin P. Hum. Mol. Genet. (2001) 10, 1221-1228)。

アミンは気体のHClを10分間バブリングする(bubbled)エーテル60mlに溶解する。媒体を−20℃に2時間置き、次いで、減圧下でろ過する。ベーンポンプを用いて溶液のトレースを除去し、E4のアンモニウムハイドロクロライド(3.75g−0.0243mol−定量的収率)を白色粉末の形で得る。

III− 本発明の分子の疎水性の測定:
本発明の1つの目的は、in vivoでの膜内外での通過及び輸送を促進するために、フリーラジカル捕捉剤であるHLBを調節することである。
logl/C=−k(log P)2+k’(log P)+k’’
C:標準的な生物学的応答を生み出すモル濃度
k、k’及びk’’:最小二乗法により決定される定数。
log Kow=a log k’+b
ここで、a及びbは、溶媒系を特徴付ける経験的な定数である。
ここで、tRは試料の保持時間を表し、及び、t0は移動相の溶出時間を表す。
y=ax+b
ここで、yはlog k’及びaはlog k’wを表し、
及び、xは溶離剤のメタノールフラクションを表す。
1− 炭化水素鎖を有する化合物の場合、得られた値は本発明者の予想と一致する。疎水性の規模は、鎖の炭素原子数に直接比例している。一方、log k’値に対する鎖の結合様式(chain junction)の役割は重要ではなく、アミドまたはウレタン結合は、チオエーテル結合より極性の性質である。従って、疎水性が高まる次の順が得られる:
A5<A1<A2
2− フッ素化化合物の場合、化合物A3は、化合物A4が示すよりも、より高い親和性を脂質媒体に示し、この観察は、これらそれぞれのCMC値に一致することが分かる。しかし、化合物A3及びA4は、互いによく似たlog k’wを有するが、一方で、これらのCMC値は2倍以上変化する。これはフッ素化された鎖の性質に由来し、これは異常な界面活性特性を示す。それゆえ、界面活性の概念と疎水性の概念の間には、明白な区別が必要である。ゆえに、疎水性が高まる次の順が得られる:
A5<A1<A2<A4<A3
3− PBNのlog k’wの値は、いずれの合成した化合物のそれよりもかなり低い。Hansch’s仮説に従うと、本発明者は、化合物がよりよい膜内外浸透性を有し、そのためフリーラジカルを捕捉する優れた活性を有することが導き出せ得る。
