Description
本発明の新規な特徴は、添付の請求項に詳細に記載する。本発明のこれらの特徴および利点は、本発明の原理を利用する例示的な実施形態を記載している下記の詳細な説明および添付の図面を参照することにより、より良好に理解されるであろう。
別段に定義されていない限り、本明細書で使用される全ての技術用語および科学用語は、本発明が属する分野の当業者に一般に理解されるものと同じ意味を有する。
式I:
1つの実施態様では、式Iの化合物を、以下のスキーム1〜7の通りに合成する。この合成の最終生成物は、式Iの化合物を、非晶質固体として、あるいは形態A〜Eなどの結晶形態として、あるいは直接的または間接的に薬学的に許容される塩として与える。この全合成ルートをさまざまに変形することにより、より優れた収率、材料原価、および/または高いキラル純度がもたらされ得る。
様々な実施態様では、式Iの化合物の非晶質形態、結晶形態A、B、C、D、もしくはEの形態、またはこれらの組合せを、医薬組成物中で投与する。本発明の医薬組成物は、被験者に適切に投与するための組成物を製剤化するために、薬学的に許容される担体および賦形剤を、式Iの化合物の非晶質、結晶形態A、B、C、D、もしくはEの形態、またはこれらの組合せと共に含む。
単一の作用メカニズムによって使用を限定することを意図しないが、本明細書に記載した方法は、式Iの化合物の非晶質、結晶形態A、B、C、D、もしくはE、またはこれらの混合物を含む式Iの化合物を投与することによって、LFA−1とICAM−1との間の相互作用を阻害することによる、炎症に関連する疾患の開始および進行の阻害を包含する。いくつかの実施態様では、この方法は、抗炎症効果をin-vitroおよびin-vivoでもたらし、炎症が介在する疾患の治療および/または疾患メカニズムの研究に有用である。
実施例2を、炭酸セシウムの代わりに炭酸カリウムを用いて繰り返した。
Bocで保護されたブロモフェニルアラニン(化合物7)(100g)を、撹拌およびアルゴンを用いて脱気しながらDMSO(400 mL)に溶解させた。メタンスルフィン酸ナトリウム(98g)、ヨウ化銅(28.7g)、炭酸カリウム(40 g)、およびL-プロリン(26.75g)を28〜30℃で添加した。反応物を約87℃にて17〜19時間加熱した。反応物を冷却し、砕いた氷を用いて反応を停止させ、30〜40分間撹拌し、クエン酸(350 g) を用いてpHを約12から約3〜4に調整した。反応を停止させた反応混合物を、ろ過し、ジクロロメタンで3回抽出し、塩化アンモニウム溶液で洗浄し、重硫酸ナトリウム溶液で洗浄し、塩水で洗浄した。ジクロロメタン中の粗生成物を減圧下で、水分含量が約0.5%未満になるまで濃縮し、さらに精製することなく次の工程に用いた。ジクロロメタン中の粗化合物8に、窒素下で撹拌しながらベンジルアルコールおよびDMPAを加えた。反応物を0〜5℃に冷却した。これに撹拌しながら30分間かけてEDC-HCL (1.03当量)を添加した。TLCおよびHPLCによって反応の完結が示された後、重炭酸ナトリウム溶液を用いて反応を停止させ、有機相を分離し、水性相をジクロロメタンで抽出した。有機相をクエン酸溶液で洗浄し、合わせた有機相を塩水溶液で洗浄した。ジクロロメタンを45〜50℃で除去し、その濃縮物を、さらに精製することなく次の工程に用いた。化合物9のアミノ基を、ジオキサン中の4NのHClを、塩化メチレン中10〜15℃の化合物9に添加することによって脱保護した。遊離のアミノ種のHCl塩である化合物10を、ジエチルエーテルからろ過によって単離した。化合物10の単離は、ジメチルホルムアミド/ジクロロメタン溶媒系を用いて再結晶することによって実施した。
