Abstract
Description
「抗生物質が関係した状態」という用語は、抗生物質療法が腸の微生物叢のバランスを乱し、病原生物、例えばクロストリジウム・デフィシレ(C.difficile)、黄色ブドウ球菌(S.aureus)及びクロストリジウム・パーフリンジェンス(C.perfringens)のエンテロトキシン産生菌が繁茂することを可能にする場合に生じる状態を表す。これらの生物は、下痢、偽膜性大腸炎及び大腸炎を引きこすことがあり、他の症状の中で下痢、尿意促迫、腹痛、テネスムス及び発熱を呈する。下痢は、重度の場合には、脱水症及び脱水症に関連した医学的合併症を引き起こす。
Xは低級アルキルから選択され、この場合に使用する「低級アルキル」という用語は、1個又は2個の炭素原子を含む分岐又は直鎖アルキル基、例えばメチル基、エチル基、n−プロピル基、イソプロピル基などを表し;及び
YはOH又はケトン(=O)から選択され;及び
ZはH又は低級アルキルから選択され、この場合に本明細書で使用する「低級アルキル」という用語は、1〜5個の炭素原子を含む分岐又は直鎖アルキル基、例えばメチル基、エチル基、プロピル基、イソプロピル基、n−ブチル基、t−ブチル基などを表す〕
の構造を有する化合物が提供される。
18員大環状化合物及びその類似化合物は、発酵によって製造される。チアクミシン類を製造するためのダクチロスポランギウム・オーランティアカム(Dactylosporangium aurantiacum)亜種ハムデネンシス(hamdenensis)AB 718C−41 NRRL 18085の培養は、炭素源、無機塩及びその他の有機成分を1種又はそれ以上の吸収剤と共に含有する培地中で適切な通気条件下、滅菌環境中で混合しながら行う。
本発明のチアクミシン化合物を含む本発明の医薬組成物、特にOPT−80(これは、ほぼ完全にR−チアクミシンからなる)は、投与時に実質的に即時に抗生物質を放出するか、あるいは投与後の所定の時間又は期間で抗生物質を放出するように製剤され得る。
R−チアクミシンB(OPT−80の主要な最も活性な成分)の正確な構造を、以下の式IVに示す。R−チアクミシンBのX線結晶構造を、メタノール中で成長させた無色の平行六面体形状の結晶(0.08×0.14×0.22mm)から得、図1にORTEP図として示す。このX線構造により、以下の式IVに示す構造が確認される。その公式な化学名は、3−[[[6−デオキシ−4−O−(3,5−ジクロロ−2−エチル−4,6−ジヒドロキシベンゾイル)−2−O−メチル−β−D−マンノピラノシル]オキシ]−メチル]−12(R)−[[6−デオキシ−5−C−メチル−4−O−(2−メチル−1−オキソプロピル)−β−D−リキソ−ヘキソピラノシル]オキシ]−11(S)−エチル−8(S)−ヒドロキシ−18(S)−(1(R)−ヒドロキシエチル)−9,13,15−トリメチルオキサシクロオクタデカ−3,5,9,13,15−ペンタエン−2−オンである。
