Description
6−O−メチルエリスロマイシンA(クラリスロマイシン)は、式:
本発明者等は、6−O−メチルエリスロマイシンAが、少なくとも2種の別個の結晶形(同定のために、「フォームI」及び「フォームII」と指定される)で存在し得ることを見出した。結晶形は、それらの赤外スペクトル、示差走査熱量測定サーモグラム及び粉末X線回折パターンによって同定される。フォームI及びフォームII結晶は、全く同一の抗菌活性のスペクトルを有するが、フォームI結晶は意外にも、フォームII結晶のものの約3倍の固有溶解速度を有する。本発明者等の研究所に於ける研究により、エタノール、テトラヒドロフラン、酢酸イソプロピル及びイソプロパノール又はエタノール、テトラヒドロフラン、酢酸イソプロピル若しくはイソプロパノールと他の一般的な有機溶媒との混合物から再結晶したとき、6−O−メチルエリスロマイシンAは、これまで確認されなかったフォームI結晶として唯一生成することが明らかになった。
(a)エリスロマイシンAを6−O−メチルエリスロマイシンAに転化する工程;
(b)6−O−メチルエリスロマイシンAを、(i)エタノール、(ii)酢酸イソプロピル、(iii)イソプロパノール、(iv)テトラヒドロフラン並びに(v)エタノール、酢酸イソプロピル、イソプロパノール及びテトラヒドロフランからなる群から選択された第一溶媒と、5〜12個の炭素原子の炭化水素、3〜12個の炭素原子のケトン、3〜12個の炭素原子のカルボン酸エステル、4〜10個の炭素原子のエーテル、ベンゼン、1〜4個の炭素原子のアルキル、1〜4個の炭素原子のアルコキシ、ニトロ及びハロゲンからなる群から選択された1個又は2個以上の置換基で置換されたベンゼン並びに極性非プロトン性溶媒からなる群から選択された第二溶媒との混合物、からなる群から選択された溶媒で処理する工程;
(c)工程(b)で生成された結晶性6−O−メチルエリスロマイシンAを単離する工程、並びに
(d)工程(c)で単離された6−O−メチルエリスロマイシンAを、環境温度と約70℃との間の温度で乾燥して、6−O−メチルエリスロマイシンAフォームIを生成する工程
からなる、6−O−メチルエリスロマイシンAフォームIの製造方法を提供する。
6−O−メチルエリスロマイシンAは、エリスロマイシンAの6−ヒドロキシ基のメチル化によって製造される。しかしながら、6位に加えて、エリスロマイシンAには11、12、2’及び4’’位にヒドロキシ基が、そして3’位に窒素が含まれており、これらの全ては潜在的に、アルキル化剤に対し反応性がある。それで、6−ヒドロキシ基をアルキル化する前に、種々の反応性官能基を保護することが必要である。代表的な6−O−メチルエリスロマイシンAの製造は、米国特許第4,331,803号、同第4,670,549号、同第4,672,109号及び同第4,990,602号並びにヨーロッパ特許明細書第260938B1号に記載されており、これらは、参照してここに組み込まれる。保護基の最終的除去に続いて、6−O−メチルエリスロマイシンAは、脱保護反応からの残留溶媒、無機塩及び他の不純物を含有する固体、半固体又はシロップとして存在し得る。6−O−メチルエリスロマイシンAフォームIは、上記の溶媒を使用して、このシロップ又は半固体から直接結晶化させることができる。また、粗製反応生成物が固化している場合、固体を上記の溶媒のいずれかから再結晶することができる。純粋な6−O−メチルエリスロマイシンAフォームIはまた、上記の溶媒系の全てからフォームII又はフォームIとフォームIIとの混合物を再結晶することによっても得ることができる。本明細書で使用されるとき、用語「6−O−メチルエリスロマイシンA」は、あらゆる純度の状態又はそれらの混合物で、6−O−メチルエリスロマイシンAフォームI又はIIを含むことが意味される。
の6−O−メチルエリスロマイシンAオキシム誘導体のメチル化、そしてR3がベンゾイルであるときには、更に脱保護、脱オキシム化及び還元性メチル化によって、6−O−メチルエリスロマイシンAが得られる。米国特許第4,672,109号参照。
のメチル化が含まれる。次いで、保護基の除去及び脱オキシム化を、一段階で酸で処理することにより行って、6−O−メチルエリスロマイシンAを得る。ヨーロッパ特許明細書第260938B1号及び米国特許第4,990,602号参照。
本発明はまた、1種又は2種以上の非毒性で薬物的に許容される担体と一緒に配合された6−O−メチルエリスロマイシンAフォームIからなる薬物組成物を提供する。この薬物組成物は特に、固体若しくは液体状で経口投与用に、非経口注射用に又は直腸投与用に製剤することができる。
