Description
化合物11−(2−ピロリジン−1−イル−エトキシ)−14,19−ジオキサ−5,7,26−トリアザ−テトラシクロ[19.3.1.1(2,6).1(8,12)]ヘプタコサ−1(25),2(26),3,5,8,10,12(27),16,21,23−デカエン(化合物I)は、PCT/SG2006/000352において初めて記載されたものであり、数多く医学的状態の治療のための薬学的活性薬剤として有意な見込みを示し、この化合物によって示される活性プロフィールに基づいてこの化合物の臨床的開発が進行中である。
本発明は、11−(2−ピロリジン−1−イル−エトキシ)−14,19−ジオキサ−5,7,26−トリアザ−テトラシクロ[19.3.1.1(2,6).1(8,12)]ヘプタコサ−1(25),2(26),3,5,8,10,12(27),16,21,23−デカエンのクエン酸塩を提供する。
上述したように、11−(2−ピロリジン−1−イル−エトキシ)−14,19−ジオキサ−5,7,26−トリアザ−テトラシクロ[19.3.1.1(2,6).1(8,12)]ヘプタコサ−1(25),2(26),3,5,8,10,12(27),16,21,23−デカエンの特定の塩が単一の頑強な多形として存在するということが今や見いだされた。特に、本出願人は、この化合物のクエン酸塩が単一の多形として存在することを見いだした。
化合物Iの塩酸塩の形成(比較例)
遊離塩基11−(2−ピロリジン−1−イル−エトキシ)−14,19−ジオキサ−5,7,26−トリアザ−テトラシクロ[19.3.1.1(2,6).1(8,12)]ヘプタコサ−1(25),2(26),3,5,8,10,12(27),16,21,23−デカエンをジクロロメタンに溶解させ、環流状態にし、活性炭で処理した。混合物を熱いうちにセライトのパッドに通してろ過し、クロロメタンで洗浄した。ろ液にメタノール性HClを加え、混合物を10〜15℃で2〜3時間かく拌した。スラリーを5〜10℃に冷却し、ろ過し、ヘプタンで洗浄し、真空オーブン中、40〜45℃で乾燥させて、塩酸11−(2−ピロリジン−1−イル−エトキシ)−14,19−ジオキサ−5,7,26−トリアザ−テトラシクロ[19.3.1.1(2,6).1(8,12)]ヘプタコサ−1(25),2(26),3,5,8,10,12(27),16,21,23−デカエン塩酸塩を得た。
クエン酸塩の形成
化合物I(50mg、0.106mmol)をTHF又はトルエン(2ml)中に懸濁させ、ゆるやかに65℃まで加熱すると、明澄な溶液になった。次いで、溶液をクエン酸1当量で処理し、65℃で1時間加熱し、ゆっくりと一晩かけて5℃まで冷まして結晶化を促進した。次いで、このようにして形成した結晶をろ過によって単離した。
クエン酸塩の形成
化合物I(50mg、0.106mmol)をTHF(2ml)中に懸濁させ、ゆるやかに65℃まで加熱すると、明澄な溶液になった。次いで、溶液をクエン酸(水溶液として)1当量で処理し、90℃で1時間加熱し、ゆっくりと一晩かけて5℃まで冷まして結晶化を促進した。次いで、このようにして形成した結晶をろ過によって単離した。
熱重量分析及び示差走査熱量測定
塩酸塩(比較)及びクエン酸塩の両試料を、以下の条件下、熱重量分析及び示差走査熱量測定に付した。50ポジションオートサンプラを装備したTA Instruments Q2000においてDSCデータを収集した。認証インジウムを使用して、エネルギー及び温度較正に関して計器を較正した。一般に、ピンホール付きアルミニウムパンの中で各試料0.5〜3mgを10℃.min-1で25℃から270℃まで加熱した。
X線回折分析
塩酸塩(比較)及びクエン酸塩の両試料をX線回折に付して特徴的なX線回折パターンを決定した。使用した条件は以下のとおりであった。X線粉末回折パターンは、Siemens D5000回折計において、CuKα放射線(40kV、40mA)、θ−θゴニオメータ、V20の発散スリット及び受光スリット、グラファイト二次モノクロメータならびにシンチレーションカウンタを使用して収集した。認証コランダム標準(NIST 1976)を使用して計器を性能チェックした。
周囲条件下で実験される試料は、粉末を使用するフラットパネル標本(flat plate specimens)としてそのままで用意した。約35mgの試料を、研磨されたゼロバックグラウンド(zero-background)(510)シリコンウェーハに切り込まれたキャビティの中にやさしく詰め込んだ。分析中、試料をそれ自体の面において回転させた。データ収集の詳細は以下のとおりであった。
・角度範囲:2〜42°2θ
・ステップサイズ:0.05°2θ
・収集時間:4s.step-1
非周囲条件下で実験される試料は、熱伝導性化合物を有するシリコンウェーハに取り付けた。そして、試料を適切な温度まで約10℃.min-1で加熱し、その後、等温で約2分間保持したのち、データ収集を開始した。
可変温度X線回折
クエン酸塩の試料の安定性を精査するために、可変温度X線回折を実施した。このように、塩を、X線回折条件下、一連の温度で走査し、特徴的なピークを決定した。各走査の結果は先に説明した図面に示されている。
