E−メタニコチン及びヒドロキシ安息香酸に由来する、本明細書に記載されているヒドロキシ安息香酸塩は、E−メタニコチン及び他の酸に由来する他の塩に対して多数の利点を有する。一般に、E−メタニコチンのヒドロキシ安息香酸塩は、高度に結晶性で、他の塩より吸湿性が低い傾向がある水溶性物質である。例えば、(2S)−(4E)−N−メチル−5−[3−(5−イソプロポキシ−3−ピリジン)イル)]−4−ペンテン−2−アミンのp−ヒドロキシ安息香酸塩は、物理的及び化学的に安定であり、自由流動性の結晶粉末である。このような特性は、薬学的製剤の開発及び医薬の製造にとって明確な利点である。必要であれば、この塩は、薬学的な処理のために、許容可能な粒径範囲へと製粉することが可能である。この塩は、固体の経口剤形の製造のために選択され得る多様な賦形剤と適合性を有する。これは、薬学的に確定された水和物である多糖誘導体などの賦形剤及び緩やかに結合した表面水のみを有する賦形剤の場合に、特に当てはまる。例示として、E−メタニコチンとフマル酸などのある種のE−メタニコチンに由来する塩は、塩内に不純物を形成する傾向がある。例えば、E−メタニコチン中の第2級アミンの、フマル酸中のオレフィンへのMichael付加反応から不純物が生じる。これらの不純物は、塩の化学的純度を低下させ、長期保存時に、塩の化学的完全性に対して悪影響を与える。
(E)−メタニコチン型化合物のヒドロキシ安息香酸塩を調製するために使用することが可能なヒドロキシ安息香酸は、以下の一般式:

本明細書に記載されている(E)−メタニコチン型の化合物が合成的に産生される様式は、変化し得る。例えば、これら化合物は、パラジウムによって触媒される芳香族ハロゲン化物のカップリング反応、及び保護されたアミン置換基を含有する末端オレフィン、第1級又は第2級アミンを取得するための保護基の除去、及び第2級又は第3級アミンを提供するために場合によって行われるアルキル化によって調製することが可能である。特に、ある種のメタニコチン型化合物は、3−ハロ置換され、場合によって5−ハロ置換されたピリジン化合物又は5−ハロ置換されたピリミジン化合物を、保護されたアミン官能基を有するオレフィン(例えば、フタルイミド塩の、3−ハロ−1−プロペン、4−ハロ−1−ブテン、5−ハロ−1−ペンテン又は6−ハロ−1−ヘキセンとの反応によって提供されるオレフィンなど)を用いた、パラジウムによって触媒されるカップリング反応に供することによって調製することが可能である。「Frank et al., J. Org. Chem., 43(15):2947−2949 (1978)」;及び「Malek et al., J. Org. Chem., 47:5395−5397 (1982)」を参照されたい。
(E)−メタニコチンヒドロキシベンゾアートは、上述したE−メタニコチン型化合物をヒドロキシ安息香酸と反応させることによって形成される。塩を調製するために使用される各成分(E−メタニコチン及びヒドロキシ安息香酸)の化学量論は、変動することが可能である。ヒドロキシ安息香酸:塩基(E−メタニコチン)のモル比は、典型的には2:1ないし1:2、より典型的には2:1又は1:1であることが典型的であるが、他の比(3:2など)が可能である。酸:塩基のモル比は1:1であることが好ましい。本発明の塩が形成される様式に応じて、本発明の塩は、塩形成の際に存在する溶媒を閉塞し得る結晶構造を有し得る。このため、本発明の塩は、アリール置換されたアミンに対する溶媒の変動する化学量論の水和物及び他の溶媒和物として生じ得る。
所望であれば、ヒドロキシ安息香酸塩が一旦単離されたら、例えば、薬学的に許容される別の酸との直接反応によって、又は(強塩基との反応及び適切な溶媒中への抽出によって)遊離塩基をまず単離した後、薬学的に許容される別の酸との反応によって他の塩形態を形成することが可能である。このような手順は、当業者に公知である。
本発明の薬学的組成物は、純粋な状態で、又は前記化合物が他の何らかの薬学的に適合性のある生成物(不活性であってもよく、又は生理的に活性であってもよい。)と組み合わされた組成物の形態で、本明細書に記載されているヒドロキシベンゾアートを含む。このような組成物は、例えば、経口、非経口、直腸又は局所的に投与することが可能である。
本明細書に記載のヒドロキシ安息香酸塩は、ニコチン性化合物の他種が治療法として提案されている状態及び疾患の種類を治療するのに有用である。例えば、Williams et al.,DN&P 7(4):205−227(1994)、Arneric et al.,CNS Drug Rev.1(1):1−26(1995)、Arneric et al.,Exp.Opin.Invest.Drugs5(1):79−100(1996)、Bencherif et al.,J.Pharmacol.Exp.Ther.279:1413(1996)、Lippiello et al.,J.Pharmacol.Exp.Ther.279:1422(1996)、Damaj et al.,Neuroscience(1997)、Holladay et al.,J.Med.Chem.40(28):4169−4194(1997)、Bannon et al.,Science 279:77−80(1998)、PCT WO94/08992、PCT WO96/31475並びにBencherifらの米国特許第5,583,140号、Dullらの米国特許第5,597,919号及びSmithらの米国特許第5,604,231号を参照する。
