Description
しかしながら、インフルエンザを適用とした薬剤は、抗菌剤などと比較してはるかに少ない。現在使用されているアマンタジンおよびオセルタミビルなどは、耐性化などの問題を有している。
抗インフルエンザウイルス剤を組み合せて使用する方法は、インフルエンザウイルスの耐性化の低減、治療効果の増強および/または副作用の低減等を目的として検討されている。しかしながら、組合せに用いられる薬剤の数が限られており、必ずしも満足できる効果が得られていない。
一方、抗ウイルス活性を有するピラジン誘導体が、知られている(特許文献1)。このピラジン誘導体は、細胞内でリボシルリン酸化を受け、ウイルスのRNAポリメラーゼを阻害することによって抗ウイルス作用を示すことが知られている(特許文献2)。
しかしながら、ノイラミニダーゼ阻害剤およびピラジン誘導体を含有する医薬組成物ならびにノイラミニダーゼ阻害剤およびピラジン誘導体を組み合せて使用する方法は、全く知られていない。
本明細書において、特にことわらない限り、ハロゲン原子とは、フッ素原子、塩素原子、臭素原子およびヨウ素原子を;アシル基とは、たとえば、ホルミル基、アセチル、プロピオニル、ブチリル、イソバレリルおよびピバロイルなどの直鎖状または分枝鎖状のC2−12アルカノイル基、ベンジルカルボニルなどのアルC1−6アルキルカルボニル基、ベンゾイルおよびナフトイルなどの環式炭化水素カルボニル基、ニコチノイル、テノイル、ピロリジノカルボニルおよびフロイルなどの複素環式カルボニル基、スクシニル基、グルタリル基、マレオイル基、フタロイル基ならびにアミノ酸(アミノ酸としては、たとえば、グリシン、アラニン、バリン、ロイシン、イソロイシン、セリン、トレオニン、システイン、メチオニン、アスパラギン酸、グルタミン酸、アスパラギン、グルタミン、アルギニン、リジン、ヒスチジン、ヒドロキシリジン、フェニルアラニン、チロシン、トリプトファン、プロリンおよびヒドロキシプロリンなどが挙げられる。)から誘導されるN末端が保護されていてもよい直鎖状または分枝鎖状のα−アミノアルカノイル基を;アルキルオキシカルボニル基とは、たとえば、メトキシカルボニル、エトキシカルボニル、1,1−ジメチルプロポキシカルボニル、イソプロポキシカルボニル、2−エチルヘキシルオキシカルボニル、tert−ブトキシカルボニルおよびtert−ペンチルオキシカルボニルなどの直鎖状または分枝鎖状のC1−12アルキルオキシカルボニル基を;アルアルキルオキシカルボニル基とは、たとえば、ベンジルオキシカルボニルおよびフェネチルオキシカルボニル基などのアルC1−6アルキルオキシカルボニル基を;アリールオキシカルボニル基とは、たとえば、フェニルオキシカルボニルなどの基を;アルアルキル基とは、たとえば、ベンジル、ジフェニルメチル、トリチル、フェネチルおよびナフチルメチルなどのアルC1−6アルキル基を;アルコキシアルキル基とは、たとえば、メトキシメチルおよび1−エトキシエチルなどのC1−6アルキルオキシC1−6アルキル基を;アルアルキルオキシアルキル基とは、たとえば、ベンジルオキシメチルおよびフェネチルオキシメチルなどのアルC1−6アルキルオキシC1−6アルキル基を;
好ましい塩としては、薬理学的に許容される塩が挙げられ、ナトリウムとの塩が、より好ましい。
R1が、水素原子;R2が、フッ素原子;R3が水素原子である化合物が好ましい。
本発明の医薬組成物によって、より重篤なインフルエンザの治療または予防などの処置が可能となる。また、使用する個々の薬剤量を減じて投与しても強い抗インフルエンザウイルス作用を示すことより、各々の薬剤の副作用を減じることが可能となる。
試験化合物として、T−705を選択した。ノイラミニダーゼ阻害剤として、GS−4071を選択した。
(1)MDCK細胞の培養
培養液10%ウシ胎児血清添加イーグルMEM培地中、5%二酸化炭素条件下、37℃で継代培養されているマージン−ダービー イヌ腎(Madin-Darby Caine Kidney)(以下、MDCKとする)細胞をエチレンジアミン四酢酸トリプシン法によって剥離し、同培地で100μLに2×104個の細胞を含むように調製した懸濁液を96ウェルプレートに播種した。5%二酸化炭素条件下、37℃で一夜培養し、単層となったMDCK細胞を得た。
試験培地として、1%ウシ血清アルブミンを含み、カナマイシン60μg/mLおよびビタミン類を通常の4倍濃度加えたイーグルMEM培地に3μg/mLとなるようL−1−トシルアミド−2−フェニルエチルクロロメチルケトン(TPCK)処理トリプシンを加えた培地を用いた。
(1)で得られたMDCK細胞の培養上清を取り除き、イーグルMEM培地ですすいだ後、各ウェルにウシ血清アルブミンおよびビタミン類を試験培地の2倍濃度含むイーグルMEM培地を100μL、試験培地の4倍濃度のTPCK処理トリプシンを含むイーグルMEM培地で4.0×103PFU/mLに調整したインフルエンザウイルス(PR/8(H1N1))液を50μLおよび設定濃度の4倍濃度のT−705またはGS−4071を含むイーグルMEM培地(T−705設定濃度(μg/mL):0.0156、0.0313、0.0625、0.125、0.25、0.5、1、2、4/GS−4071設定濃度(μg/mL):0.00313、0.00625、0.0125、0.025、0.05、0.1、0.2、0.4、0.8)または5:1の重量濃度比になるよう混合したT−705およびGS−4071を設定濃度の4倍含む同培地を50μL加えた。
薬剤添加後、5%二酸化炭素条件下、35℃で2日間培養した。
インフルエンザウイルスの増殖に伴って認められる細胞変性効果(CPE)は、ジャーナル・オブ・ビロロジカル・メソッズ(J. Virol. Methods)、2002年、第106巻、p.71〜79およびプロシーディングズ・オブ・ザ・ナショナル・アカデミー・オブ・サイエンス(Proc. Natl. Acad. Sci.)1998年、第95巻、p.8874〜8849に記載の方法により判定した。
培養終了後、カルシウム・マグネシウム不含ダルベッコリン酸緩衝液で希釈した0.033%ニュートラルレッド溶液を各ウェルに100μL加え、5%二酸化炭素条件下、35℃で静置した。2時間後、ウェル内の液を吸引除去し、100μLのカルシウム・マグネシウム不含ダルベッコリン酸緩衝液で2回すすいだ後、各ウェルに0.1mol/Lクエン酸ナトリウムおよび0.1mol/L塩酸を含む緩衝液(pH4.2)とエタノールを容量比1:1で混合した液を100μL加え、遮光下、室温に静置した。30分後にマイクロプレートリーダー(バイオ−ラッド(BIO-RAD)Model 550)にて吸光度(540nm)を測定した。非感染コントロールは、インフルエンザウイルス液の代わりに試験培地の4倍濃度のTPCK処理トリプシンを含むイーグルMEM培地50μLを加え、試験群と同様の操作を行い、吸光度を測定した。ブランクには、MDCK細胞を播種しないウェルに非感染対照と同様の操作を加え、吸光度を測定した。例数は、8で実施し、平均値を用い、ブランクの値を差引いた数値を吸光度とした。非感染コントロールの吸光度から感染コントロールの吸光度を差引いた値をウイルス増殖の完全抑制値とし、以下に示す式から各試験のウイルス増殖抑制率を算出した。
ウイルス増殖抑制率=[(単剤および併用作用時の吸光度)−(感染コントロールの吸光度)]/[(非感染コントロールの吸光度)−(感染コントロールの吸光度)]
単剤および二剤併用時の濃度、併用比率およびウイルス増殖抑制率から、SAS release 8.2(SASインスティチュートジャパン)を用いて、チョウ(Chou)らのメディアンエフェクト(Median effect)法を用いて解析した。アドバンスド・エンザイム・レギュレーション(Advanced Enzyme Regulation)1984年、第22号、p.27〜55に示された方法のうち、作用機序が完全に独立している薬剤同士(mutually nonexclusive drug)の場合の方程式を用いCI値を算出した。併用効果の判定は、タイラ(Taira)らの論文[アクタメディカ岡山(Acta Medica Okayama.)2006年、第60号、p.25〜34]の記載に準じ、CI≦0.8のとき相乗、0.8<CI<1.2のとき相加、1.2≦CIのとき拮抗とし、50%ウイルス増殖抑制時のCI値で判定した。
試験化合物として、T−705を選択した。ノイラミニダーゼ阻害剤として、ザナミビルを選択した。試験例1に記載の方法により同様の試験を行った。
試験化合物として、T−705を選択した。ノイラミニダーゼ阻害剤として、GS−4071を選択した。インフルエンザウイルスとしてVictoria/3/75(H3N2)を用いて、試験例1に記載の方法により同様の試験を行った。
試験化合物として、T−705を選択した。ノイラミニダーゼ阻害剤として、ザナミビルを選択した。試験例3に記載の方法により同様の試験を行った。
