I.1.クレアチンからのエステルの直接合成。
本発明者らは、[7−8]に開示された手順を用いてクレアチンステアロイルエステルを調製しようとした。結果は、表1に示されている。
本発明者らは、保護されたクレアチンを使用することによってクレアチン脂肪エステルを調製しようとした。[12−13]に従ってクレアチン上で2つの保護基(PG)を発生させた(表2参照のこと)(スキーム2を参照のこと)。
プロトコールおよび収率が、表3にまとめられている。
II.1.一般的手順
この合成は、ステアロイルアルコールによってジ保護クレアチニン、(Z2)−クレアチニンの環を開くことと、それに続く、水素/Pd下での脱保護によって実施される。本明細書において以下、スキーム3は、クレアチンステアロイルエステル調製の合成順序を示す:
窒素下で、100mlの無水ジクロロメタン中、クレアチニン(1.124g−1当量)を有するジイソプロピルエチルアミン(5.2ml−3当量)の溶液に、クロロギ酸ベンゾイル(4.2ml−3当量)を加えた。クロロギ酸ベンゾイルは、氷浴中に滴加する。混合物を、氷浴中で30分および室温で一晩、撹拌しながら反応させる。
反応は、CCM(シリカ、ヘプタン/酢酸エチル)およびLC/MSによって管理する。反応媒体を、ジクロロメタンおよび水の添加によって抽出する。ジクロロメタン相を、水で3回洗浄し、硫酸マグネシウムによって乾燥した。
ジクロロメタン溶液を、真空下での蒸発によって濃縮し、結晶化させる。3.25gの粗(Z2)−クレアチニンが得られる(87%)。(Z2)−クレアチニンは、構造の決定のためにシリカゲル(ヘプタン/酢酸エチル勾配)上で精製され得る。粗生成物を使用して、エステル化ステップを実施する。
80℃に加熱した試験管中でステアロイルアルコール(alcool)(0.5g−2当量)を、1当量の粗(Z2)−クレアチニンと5時間反応させる。反応を、CCM(シリカ、ヘプタン/酢酸エチル)およびLC/MSによってモニタリングする。
粗(Z2)−クレアチンステアロイルエステルを、シリカゲル(ヘプタン/酢酸エチル勾配)上で精製し、286mgの純粋な(Z2)−クレアチンステアロイルエステルを50%の収率で得る。
純粋な(Z2)−クレアチンステアロイルエステル(140mg)を、窒素下で無水ジクロロメタン/メタノール溶液(6ml/12ml)中に溶解する。Pd/Al2O3 5%(20mg)を加える。反応混合物を、真空下で脱気し、パージされるよう凍結し、真空を水素によって破壊する。水素を用いるパージを3回行う。次いで、媒体を室温にし、激しい撹拌下で反応させる。
A.クレアチニンの保護。
アルコール基を有する種々の分子を、ジ保護クレアチニンへの求核付加について試験した。結果は、表5に示されている。
Z基の脱保護は、その極めて極性の特徴について周知であるグアニジン官能基の回復につながる。
脂肪エステルの透過性を評価するために使用されるin−vitro細胞ベースBBBモデルは、グリア細胞および脳内皮細胞の同時培養からなる。
