本発明による化合物の合成に必要な出発物質は市販されているか、または常法によって容易に製造できる。例えば、4−クロロキノリン誘導体はOrg.Synth.Col.Vol.3,272(1955),Acta Chim. Hung.,112,241(1983)、または、WO98/47873などに記載されるような慣用的手段によって合成することができる。
【0052】
あるいは、4−クロロキナゾリン誘導体は、まず、(1)安息香酸エステルをホルムアミドと反応させてキナゾロン誘導体を得、ついで(2)トルエンまたはスルホランを溶媒として使用してオキシ塩化リンの存在下、4−キナゾロン誘導体を加熱することにより製造できる。キナゾロン誘導体は安息香酸エステル、ナトリウムメトキシド、ホルムアミド、およびN,N−ジメチルホルムアミドやメタノールのような溶媒の存在下で合成するのが一般的である。
【0053】
つぎに、適当な溶媒中あるいは無溶媒中において、ニトロフェノールに対し4−クロロキノリン誘導体あるいは相当するキナゾリン誘導体を作用させ、4−(ニトロフェノキシ)キノリン誘導体あるいは相当するキナゾリン誘導体を合成した後、適当な溶媒(例えば、N,N−ジメチルホルムアミド)中、触媒(例えば、水酸化パラジウム−炭素、パラジウム−炭素) の存在下、水素雰囲気下において攪拌すると4−(アミノフェノキシ)キノリン誘導体あるいは相当するキナゾリン誘導体が得られる。あるいはまた、アミノフェノールに対し、塩基(例えば、水素化ナトリウム)の存在下、4−クロロキノリン誘導体あるいは相当するキナゾリン誘導体をさせると4−(アミノフェノキシ)キノリン誘導体あるいは相当するキナゾリン誘導体が得られる。
【0054】
あるいは、4−(アミノフェノキシ)キナゾリン誘導体は、アミノフェノールを水酸化ナトリウム水溶液に溶解し、有機溶媒に溶解した4−クロロキナゾリン誘導体と相関移動触媒(例えば、テトラ−n−ブチルアンモニウムブロミド)の存在下、または触媒なしで、2相系反応させることによって製造できる。

化合物の用途 医薬組成物
本発明における化合物は、インビボにおいて腫瘍増殖抑制作用を有する(薬理試験例2、3、および4)。
【0062】
本発明による化合物は、また、インビトロにおいてヒトKDRを安定に発現するNIH3T3細胞をVEGF(vascular endothelial growth factor)で刺激したときに起こるヒトKDR細胞内領域の自己リン酸化活性を阻害する(薬理試験例1)。VEGF がVEGFのレセプターとして細胞膜上に存在するKDRに結合すると、KDR細胞内領域のチロシンキナーゼによる自己リン酸化を介し、MAPK(mitogen−activated protein kinase)の活性化などを引き起こす(Shibuya M, Ito N, Claesson−Welsh L., in Curr. Topics Microbiol Immunol., 237, 59−83 (1999); Abedi, H. and Zachary, I., J. Biol. Chem., 272, 15442−15451 (1997))。MAPKの活性化は血管新生における血管内皮細胞の増殖に重要な役割を担うことが知られている(Merenmies, J. et al., Cell Growth & Differ., 83−10 (1997); Ferrara, N. and Davis−Smyth, T., Endocr. Rev., 18, 4−25 (1997))。従って本発明による化合物は血管新生抑制作用を有する。
【0063】
病態部位における血管新生は、主として、腫瘍、糖尿病性網膜症、慢性関節リウマチ、乾癬、アテローム性動脈硬化症、カポジ肉腫のような疾患、ならびに固形癌の転移と深く結びついていることが知られており(Folkman, J. Nature Med. 1: 27−31 (1995); Bicknell, R., Harris, A. L. Curr. Opin. Oncol. 8: 60−65 (1996))、本発明による化合物は、これらの治療に用いることができる。
【0064】
本発明によれば、本発明による化合物を含む医薬組成物が提供される。本発明による医薬組成物は腫瘍、糖尿病性網膜症、慢性関節リウマチ、乾癬、アテローム性動脈硬化症、カポジ肉腫のような疾患、ならびに固形癌の転移の治療に用いることができる。
【0065】
本発明による化合物は、経口および非経口(例えば、静脈内投与、筋肉内投与、皮下投与、直腸投与、経皮投与)のいずれかの投与経路で、ヒトおよびヒト以外の動物に投与することができる。したがって、本発明による化合物を有効成分とする医薬組成物は、投与経路に応じた適当な剤型に処方される。
【0066】
具体的には、経口剤としては、錠剤、カプセル剤、散剤、顆粒剤、シロップ剤などが挙げられ、非経口剤としては、注射剤、座剤、テープ剤、軟膏剤などが挙げられる。
【0067】
これらの各種製剤は、通常用いられている賦形剤、崩壊剤、結合剤、滑沢剤、着色剤、希釈剤などの薬学上許容される担体を用いて常法により製造することができる。
【0068】
賦形剤としては、例えば、乳糖、ブドウ糖、コーンスターチ、ソルビット、結晶セルロースなどが、崩壊剤としては、例えば、デンプン、アルギン酸ナトリウム、ゼラチン末、炭酸カルシウム、クエン酸カルシウム、デキストリンなどが、結合剤としては例えばジメチルセルロース、ポリビニルアルコール、ポリビニルエーテル、メチルセルロース、エチルセルロース、アラビアゴム、ゼラチン、ヒドロキシプロピルセルロース、ポリビニルピロリドンなどが、滑沢剤としては、例えば、タルク、ステアリン酸マグネシウム、ポリエチレングリコール、硬化植物油などがそれぞれ挙げられる。
【0069】
また、上記注射剤は、必要により緩衝剤、pH調整剤、安定化剤、等張化剤、保存剤などを添加して製造することができる。
【0070】
本発明による医薬組成物中、本発明による化合物の含有量は、その剤型に応じて異なるが、通常全組成物中0.5−50重量%、好ましくは、1−20重量%である。
【0071】
投与量は患者の年齢、体重、性別、疾患の相違、症状の程度などを考慮して、個々の場合に応じて適宜決定されるが、例えば0.01−100mg/kg、好ましくは、0.1−50mg/kgの範囲であり、これを1日1回または数回に分けて投与する。
【0072】
本発明による化合物は他の医薬と組み合わせて投与することができる。投与は、同時にあるいは経時的にすることができる。例えば、対象疾患が悪性腫瘍の場合、本発明による化合物を標的となる血管の血管内皮細胞に作用させることにより腫瘍を退縮させ、ついで、抗癌剤を投与することにより腫瘍を効果的に消滅させることができる。抗癌剤の種類や投与間隔等は癌の種類や患者の状態に依存して決定できる。悪性腫瘍以外の疾患も同様に治療できる。
【0073】
本発明によれば、腫瘍、糖尿病性網膜症、慢性関節リウマチ、乾癬、アテローム性動脈硬化症、およびカポジ肉腫からなる群から選択される疾患の治療に用いられる医薬の製造のための、本発明による化合物の使用が提供される。
【0074】

【0075】
本発明によれば、更にまた、本発明による化合物を標的血管の血管内皮細胞と接触させることを含んでなる、標的血管の血管新生を阻害する方法が提供される。標的血管としては、疾患の原因となる組織(例えば、腫瘍組織、網膜症組織、関節リウマチ組織)への栄養補給に関与する血管が挙げられる。本発明による化合物と血管内皮細胞との接触は、例えば、全身投与(静脈内投与、経口投与等)、局所投与(経皮投与、関節内投与等)、キャリアーを用いる薬物ターゲティング(リポソーム、リピッドマイクロスフェアー、高分子化医薬等)により実施できる。

Pharmacological Test Example 1: Measurement of KDR phosphorylation inhibitory activity using ELISA method
NIH3T3 cells transfected with human KDR (Sawano A et al., Cell Growth & Differentiation, 7, 213-221 (1996), "Flt-1 but not KDR / Flk-1 tyrosinase catalysate catalysate catalysate catalysed pharmacokinetic activity. whis is related to vascular environmental growth factor ") was cultured in a DMEM medium (purchased from GIBCO BRL) containing 10% fetal bovine serum in a 5% carbon dioxide gas incubator until it became 50-70% confluent. Harvested cells were plated in a collagen type 1 coated 96-well flat bottom plate with the same medium at 1.5 × 10 54The cells were seeded at a number of cells / well and cultured at 37 ° C. overnight. The medium was replaced with a DMEM medium containing 0.1% fetal calf serum, a test substance dissolved in dimethyl sulfoxide was added to each well, and the cells were further cultured at 37 ° C. for 1 hour. Human recombinant vascular endothelial growth factor (hereinafter abbreviated as VEGF) was added to a final concentration of 100 ng / ml, and the cells were stimulated at 37 ° C. for 2 minutes. After removing the medium and washing the cells with phosphate buffered saline (pH 7.4), a solubilization buffer (20 mM HEPES (pH 7.4), 150 mM NaCl, 0.2% Triton X-100, 10% Glycerol, 5 mM Sodium orthovanadate, 5 mM disodium ethylenediaminetetraacetate, 2 mM Na4P2O7) Was added and shaken at 4 ° C. for 2 hours to prepare a cell extract.
[0154]
To a microplate for ELISA (Maxisorp; purchased from NUNC), 50 μl of phosphate buffered saline (pH 7.4) containing 5 μg / ml of anti-phospho-tyrosine antibody (PY20; purchased from Transduction Laboratories) was added, and 4 ° C. And allowed to stand overnight for solid phase immobilization. After washing the plate, 300 μl of a blocking solution was added, and the mixture was allowed to stand at room temperature for 2 hours to perform blocking. After washing, the entire amount of the above cell extract was transferred and allowed to stand at 4 ° C. overnight. After washing, an anti-KDR antibody (purchased from Santa Cruz) was reacted for 1 hour at room temperature, and after washing, a peroxidase-labeled anti-rabbit Ig antibody (purchased from Amersham) was reacted for 1 hour at room temperature. After washing, a chromogenic substrate for peroxidase (purchased from Sumitomo Bakelite) was added to start the reaction. After an appropriate color was obtained, a reaction stop solution was added to stop the reaction, and the absorbance at 450 nm was measured using a microplate reader. The KDR phosphorylation activity of each well was determined by taking the absorbance when VEGF was added without adding a drug as 100% KDR phosphorylation activity, and the absorbance when no drug and VEGF were added as 0% KDR phosphorylation activity. Was. By changing the concentration of the test substance in several steps, the inhibition rate against the phosphorylation of KDR in each case was determined, and the 50% inhibitory concentration of the KDR phosphorylation of the test substance (IC50) Was calculated.
