To provide stable, crystalline, water-soluble forms of substituted 3-cyanoquinoline compounds that selectively inhibit kinase activity and then inhibit cell proliferation and tumorigenesis.SOLUTION: The present invention relates to maleate salt forms of (E)-N-{4-[3-chloro-4-(2-pyridinylmethoxy)anilino]-3-cyano-7-ethoxy-6-quinolinyl}-4-(dimethylamino)-2-butenamide, methods of preparing crystalline maleate salt forms, associated compounds, and pharmaceutical compositions containing the maleate salt forms. The maleate salts are useful in treating cancers, particularly those affected by kinases of the epidermal growth factor receptor family.SELECTED DRAWING: Figure 1 【課題】キナーゼ活性を選択的に阻害し、次いで細胞増殖および腫瘍形成を阻害する置換３−シアノキノリン化合物の安定な結晶水溶性形態を提供すること。【解決手段】本発明は、（Ｅ）−Ｎ−｛４−［３−クロロ−４−（２−ピリジニルメトキシ）アニリノ］−３−シアノ−７−エトキシ−６−キノリニル｝−４−（ジメチルアミノ）−２−ブテンアミドのマレイン酸塩形態、結晶マレイン酸塩形態を調製する方法、関連する化合物、およびそのマレイン酸塩形態を含有する医薬組成物に関する。このマレイン酸塩は、癌、特に上皮増殖因子受容体ファミリーのキナーゼの影響を受ける癌の治療に有用である。【選択図】図１
