(2) 反応を室温に放冷し、水を加え、混合物をろ過し、ろ過ケーキを真空下で乾燥し、中間体1を得る。或いは、反応を室温に放冷し、水を加え、混合物を有機溶媒(例、酢酸エチル、ジクロロメタン又はクロロホルム)で抽出し、次いで、有機層を留去乾燥し、中間体1を得る。
(1) 中間体1をまとめて溶媒(例、エタノール又はTHF等)(酸(例、酢酸又は希塩酸等)が含まれていてもよい)に加える。次いで、還元剤(例、Fe粉末、Zn粉末、Pd/C又はRaney−Ni等)を加える。反応は室温或いは加熱下で行う。
(2) 反応完結後、反応混合物を室温に放冷し、有機溶媒(例、ジクロロメタン、酢酸エチル又はクロロホルム等)で抽出し、有機層を留去乾燥し、得られた粗生成物をカラムクロマトグラフィ(シリカゲルカラム又は分取クロマトグラフィカラム)で精製し、中間体2を得る。
(1) 中間体2を有機溶媒(例、THF、ジクロロメタン、アセトニトリル又はDMF等)に溶解し、続いて、混合物に、有機塩基(例、トリエチルアミン又はDIEA等)及び原料3を加え、混合物を室温で数時間撹拌し、反応させる。或いは、中間体2、原料3及び有機塩基(例、DIEA又はトリエチルアミン等)を有機溶媒(例、ジクロロメタン、DMF、THF、アセトニトリル又はDMF等)に溶解し、縮合剤(例、HATU(2-(7-アゾベンゾトリアゾール-1-イル)-N,N,N',N'-テトラメチルウロニウム ヘキサフルオロリン酸塩)、EDC(1-エチル-3-(3-ジメチルアミノプロピル)カルボジイミド)又はDCC(N,N'-ジシクロヘキシルカルボジイミド)等)を加える。
(2) 水を反応混合物に加え、混合物を有機溶媒(例、ジクロロメタン、酢酸エチル又はクロロホルム等)で抽出し、有機層を合わせ、得られた残渣をカラムクロマトグラフィ(シリカゲルカラム又は分取クロマトグラフィカラム)で精製し、式(I)の化合物を得た。

1) 細胞の解凍:
・細胞凍結チューブを液体窒素から取り出し、37℃-39℃の水浴中に入れ、急速に細胞に解凍した。

1) 細胞懸濁液の調製
・培地を培養瓶から除去した。細胞をPBSで二度すすぎ洗った。膵酵素を加え、細胞を消化した。消化された細胞を遠心分離し回収した。細胞を10% ウシ胎児血清を含む培地で再懸濁し、カウントし、適切な濃度(細胞生存率は90%を超えるようにするべき)に調整した。細胞濃度は5×104/mlとした。
薬剤を細胞培養プレートに加えた。インキュベータにプレートを入れ、37℃で5% CO2下72 時間インキュベートした。
XTT使用溶液をプレートに加えた。プレートをインキュベータに入れ、37℃で5%CO2下2 時間インキュベートした。次いで、プレートをマイクロプレートリーダに入れ、450 nmで吸光度を読み取った。
1) パーセント阻害を以下の計算式で計算した。
%阻害剤=(吸光度(媒体)−吸光度(化合物))/(吸光度(媒体)−吸光度(陽性対照)×100%;
2) データをGraphPad Prism 5.0に入力し、曲線にプロットし、IC50を得た。
結果:
表2から、本発明化合物のH1975 (NSCLC, 非小細胞肺癌)に対する細胞増殖阻害効果が、エルロチニブ塩酸塩及びトシル酸ラパチニブに比べて非常に優れていることがわかる。
