Description
1269795 五、發明說明(1) 發明之範# 本發明係關於5-曱氧基-2-[ [ (4-曱氧基-3, 5 -二曱基-2-吡啶基)-曱基]亞磺醯基]-1 H-苯并咪唑(其一般名為奧美 拉唑)。更特定而言,其係關於5 -曱氧基-2-[[(4-曱氧基 - 3, 5 -二甲基-2 -吡啶基曱基]亞磺醯基]-1H-苯并咪唑之 (S)-對掌異構體之鉀鹽新穎結晶形式。本發明也關於一種 製備該(S)-奥美拉唑之鉀鹽形式之方法,及包含該化合物 的醫藥組合物。 本發明背景及先前技藝
化合物5-曱氧基-2-[[(4-曱氧基-3, 5 -二曱基-2 -吡啶 基)-甲基]亞續醯基]-1II -苯并味嗤(一般名為奧美拉嗤)及 其治療上可接受之鹽被記載在EP 51 29中。EP 1 24 4 9 5揭 示奧美拉唑之特異性鹼性鹽。奧美拉唑是一種質子幫浦抑 制劑,能有效抑制胃酸分泌,因此為一種有用的抗潰癌 劑。更廣泛地說,奥美拉唾可用來防止及治療哺乳類(特 別是人類)的胃酸相關疾病。
奧美拉唑是一種亞楓及鏡像化合物,其中硫原子為鏡像 中心,因此,奥美拉唑為其兩種對掌異構體(R )-及(S )(即 (R)-奧美拉σ坐及(S )-奧美拉唾)的消旋混合物。奥美拉嗤 之對掌異構體的絕對構形已經由對一種非鹽形式之(+ )-對 掌異構體之Ν -烷化衍生物進行X光研究而得知。 該非鹽形式之(+ )-對掌異構體及非鹽形式之(-)-對掌異 構體分別具有R及S構形。W0 94/ 279 88揭示測量上述對掌 異構體之旋光性的條件。
第5頁 1269795 五、發明說明(2) W0 9 4/279 88揭示奥美拉唑之單-對掌異構體的某些鹽類 及其製法’這些化合物具改良的藥物動力及代謝性質,而 賦予改良的治療模式(p r 〇 f i 1 e ),如個體差異較低。 W0 96/02535揭示一種製備奧美拉唑之單-對掌異構體及 其結構相關化合物及鹽之方法。UO 9 6/ 0 1 623揭示一種包 含(R ) _及(S )-奥美拉唑之鎂鹽之醫藥劑型。
WO 98/54171揭示一種製備(S) -奧美拉唑之鎂鹽之三水 合物之方法,其中(S )-奥美拉唑之鉀鹽被用作中間物。根 據先前技藝所述,(S) -奥美拉唑之鉀鹽結晶成一種曱醇溶 劑合物。 (S)-奥美拉唑之某些鹽如鉀鹽因其内因性特質(諸如高 安定性及在水中的高溶解度)通常為適合靜脈注射之化合 物,然而曱醇溶劑合物並不適合靜脈注射,因為合併注射 甲酵會導致被注射者死亡,因此需要一種不含曱醇的(S)-與美拉唑鉀鹽。 在後文中,本發明之新穎(S)-奥美拉唑鉀鹽被稱為(S)-與美拉唑鉀鹽B型,而按照W 〇 9 8 / 5 4 1 7 1之(s )-奧美拉唑鉀 鹽之先前技藝形式被稱為(S)-奥美拉唑鉀鹽A型。
圖式之簡要說明 圖1為根據本發明製備之(S)-奧美拉唑之鉀鹽B型的X光 粉末繞射光譜。 圖2為根據w〇 9 8 / 5 4 1 7 1實例2製備之(S )—奥美拉唑之鉀 獴A塑的X光粉末繞射光譜。 發明之說明
