(a)本発明の化合物はより低い毒性を有する。
ステップ1:Ly101-38の合成
ステップ1:Ly101-41の合成
ステップ1:Ly101-42の合成
表Aの他の化合物は、異なる実施例1-22と同様の方法で調製した。
THP-1細胞株は、ATCC(American Type Culture Collection,Manassas,VA:アメリカンタイプカルチャーコレクション、米国バージニア州マナッサス)から購入した。37℃、5% CO2条件下で、10%熱不活性化ウシ血清、100倍Glutamax培地、及び0.05mMのβ-メルカプトエカノールを補充した増殖培地(Growth medium)(RPMI-1640)で細胞を維持した。化合物を0.1% DMSOに溶解した。エリスロマイシンを陽性コントロールとして使用した。
気管支上皮の主な機能は、正常な気道機能の維持を助ける防御バリアとして機能することである。気管支上皮細胞(BEC)は外部環境と内部環境の間のインターフェースを形成し、吸入による傷害の主要な標的となっている。BECは、炎症細胞をリクルートして活性化するケモカインやサイトカインを放出することにより、免疫と炎症反応を開始及び調整するエフェクターとしても機能できる。NF-κB、IL-6、IL-8などのサイトカインの分泌を測定することにより、様々なマクロライド誘導体の抗炎症効果を評価した。
BEAS-2B細胞株におけるIL-8発現阻害に対する実施例の化合物の効果を評価するために、最終容量1mLのアッセイ培地で、24ウェルプレートに100,000/mLの密度で細胞をプレーティングした。細胞を37℃、5% CO2で1日間インキュベートした。インキュベーション後、2日目に化合物を、3日目にLPSを添加した。1mMから開始して、DMSO中で3連の5点10倍又は2倍の段階希釈を行うことによって化合物ソースプレートを調製した(アッセイ中の実施例の化合物の最終最高濃度は100μMであり、DMSOは0.1%であった)。陽性コントロールは100μMエリスロマイシン処理細胞で構成され、陰性コントロールは0.1% DMSO処理細胞で構成された。10mgのLPS粉末を2mLのddH2Oに溶解して5mg/mLのLPSストック溶液を調製し、1バイアル当たり100μLにアリコートした。アッセイにおけるLPSの最終濃度は、培地でストック溶液を125倍に希釈することにより20μg/mLであった。
生後8週齢の雄C57BL/6Jマウス(Shanghai Xipuer Yibikai社から購入)をランダムに6群に分けた:生理食塩水(50μL)を気管内に注入した、対照群(コントロール);ブタ膵臓エラスターゼ(PPE、Sigma Chemical Co.,米国ミズーリ州セントルイス)(50μL生理食塩水中0.1UI)を同じ経路で投与した、肺気腫群;気管内にPPEを投与し、低/中/高用量の化合物Aを経口投与した、肺気腫+化合物A群;PPEを気管内投与し、エリスロマイシン100mg/mLを経口投与した、肺気腫+エリスロマイシン(EM)群。生理食塩水とPPEを週1回、4週間気管内注射した。化合物A及びエリスロマイシンを1日2回、4週間投与した。4週間後、全マウスを10%塩素水和物の腹腔内注射で犠牲にした。化合物Aは、LY101-25、LY101-22、LY101-45、LY101-39、LY101-33、LY101-27及びLY101-48から選ばれる化合物であった。肺組織を25cmH2Oの圧力で4%パラホルムアルデヒドで膨張させ、ホルマリン中で24時間固定し、パラフィンを包埋し、矢状面で切断し、ヘマトキシリン及びエオシン(H&E)で染色した。肺気腫の定量化は、解析ソフトウェアImage Jを用いて肺胞の平均コード長を測定することにより行った。
化合物Aによる治療でエラスターゼ誘発性肺気腫が減少した。エラスターゼを注入したマウスではびまん性の肺気腫病変がみられ、生理食塩水を注入したマウスと比べて肺胞の平均コード長(mean alveolar chord length)が著しく増加した。(図3及び図4)。化合物Aの治療により、投与量に依存して肺形態が改善し、平均コード長(mean chord length)が短縮した。100mg/mL投与時の平均コード長の最大26%の減少に達した。
この研究では、1本のタバコにつき11mgのタールと0.9mgのニコチンを含む市販のフィルターなしのタバコを使用した。8週齢の雄のC57BL/6Jマウス(Shanghai Xipuer Yibikai animal Coから購入)は、以下の4群に分けられた:第1群は対照群(NS6m)、第2群は動物モデルCS群(CS6m)、第3群はCS+化合物A 100mpk群(LY100)、第4群はCS+エリスロマイシン群(EM100)であった。マウスを使い捨てフィルターで覆われたプレキシガラスチャンバーに入れた。動物は、1日2回、週5日、24週間、1回当たり5本のタバコのCSを受けた。主流のCSは、タバコの燃焼が蠕動ポンプを介してマウスチャンバーに引き込まれる曝露システムによって生成された。第3群及び第4群では、マウスに化合物A(100mg/kg)を12週目から24週目まで1日2回経口投与した。最後のCS曝露から1週間後、血漿、気管支肺胞洗浄液(BALF)及び肺組織採取のために10%抱水クロラールを腹腔内注射して動物を犠牲にした。
化合物Aは、CS誘発COPDマウスの気道の組織病理学的変化を妨げた。肺切片の組織学的分析によると、CS群は、コントロールマウスに比べて炎症細胞の浸潤が多く、肺胞の増大が認められた。このような変化は化合物Aとエリスロマイシンの処理により著しく減衰した。
急性毒性試験は、OECDガイドライン423に従い、固定用量法を用いて行われた。簡単に言えば、研究は、各群の1性別から3匹の動物を用いて、5、50、300及び2000mg/kgの固定用量として実施された。最終用量を選択し、他の性別の3匹の動物をテストした。動物の肉眼的及び顕微鏡的な病理を決定した。行動、生化学的パラメータ及び死亡率も記録した。
雄のスパラグー・ダウリー(Sprague-Dawley)ラットに、エリスロマイシン又は化合物Aの100mg/kgを単回経口投与した(群当たりN-=3)。別の研究では、絶対的な経口バイオアベイラビリティとクリアランスのパラメータを得るために、側尾静脈を介して投与した後、ラット(N=3)に2つの化合物を30mg/mLの用量で単回静脈内投与した。化合物(10mg/mL)をIV注射用30% DMSOに溶解し、IG用0.5%CMC-Naにそれぞれ懸濁させた。エリスロマイシン又は化合物Aの静脈内(i.v.)投与の0.083、0.25、0.5、1、2、4、8、12、及び24時間後、及びエリスロマイシン又は化合物Aの経口(i.g.)投与の0.25、0.5、1、2、4、6、8、12時間後及び24時間後で採血した。プラズマ中の2つの化合物の濃度を、部分的に検証されたLC-MS/MS法によって測定した。
