Definitions
- the present invention relates to an antitumor agent comprising a combination of a pyrazolo [3,4-d] pyrimidine compound or a salt thereof and another antitumor agent, and an antitumor effect enhancer of the other antitumor agent.
- HER2 (also called ErbB2) is a receptor tyrosine kinase that belongs to the ErbB family.
- HER2 is considered as a cancer-causing gene (Non-patent document 1), and HER2 gene amplification, mutation, overexpression, and the like have been reported in various cancers (Non-patent document 2). It has been reported that in cancer cells with HER2 gene abnormality / overexpression, HER2 and downstream pathway signals are activated to enhance survival / proliferation signals of cancer cells (non-) Patent Documents 3 and 4). Therefore, an inhibitor capable of controlling the HER2 kinase activity is expected to exert an antitumor effect by inhibiting HER2 and downstream pathway signal transduction in cancer cells, and thus is useful as a cancer therapeutic agent. it is conceivable that.
- trastuzumab has been reported to be used in combination with paclitaxel (Non-Patent Document 5), paclitaxel / platinum compound (Non-Patent Document 6), and the like.
- lapatinib has been reported to be used in combination with capecitabine (Non-patent document 7), 5-FU (Non-patent document 8), S-1 (Non-patent document 9), and the like.
- lapatinib is known to exhibit a high inhibitory activity against EGFR (Epidmal growth factor receptor) in addition to HER2, and there is concern about side effects due to inhibition of the EGFR signal pathway.
- An object of the present invention is to provide a cancer treatment method using a pyrazolo [3,4-d] pyrimidine compound or a salt thereof that exhibits excellent antitumor effects while suppressing the occurrence of side effects.

Abstract
Description
HER2は、がん原因遺伝子として考えられており(非特許文献1)、HER2の遺伝子増幅や変異、過剰発現等が様々ながんで報告されている(非特許文献2)。これらHER2の遺伝子異常・過剰発現を伴うがん細胞においては、HER2及び下流pathwayのシグナルが活性化することによりがん細胞の生存・増殖シグナル等が亢進していることが報告されている(非特許文献3,4)。
従って、HER2のキナーゼ活性を制御できる阻害剤は、がん細胞におけるHER2及び下流pathwayのシグナル伝達を阻害することにより抗腫瘍効果を発揮することが想定されるため、がん治療薬として有用であると考えられる。

HER2リン酸化活性に対する化合物のインビトロでの阻害活性測定法の条件設定において、パーキンエルマー社のProfilerPro Peptide 22と同配列(5-FAM-EEPLYWSFPAKKK-CONH2)のペプチドを基質として用いたHER2キナーゼ反応の報告(PLoS One,6(7),e21487,2011)に基づき、ProfilerPro Peptide 22を基質に用いた。試験に用いた精製リコンビナントヒトHER2蛋白質はカルナバイオサイエンス社から購入した。
化合物の阻害活性測定においては、まず、合成例化合物をジメチルスルホキシド(DMSO)で段階希釈した。次に、キナーゼ反応用緩衝液(15mM Tris(pH 7.5)、2mM dithiothreitol、0.01% Tween20)中にHER2蛋白質、基質ペプチド(終濃度は0.5μM)、塩化マンガン(終濃度は10mM)、ATP(終濃度は6μM)と合成例化合物DMSO溶液(DMSOの終濃度は5%)を加えて25℃で40分間インキュベーションしキナーゼ反応を行った。そこへ終濃度30mMになるようEDTAを加えることで反応を停止させた。最後に、LabChip(登録商標) EZ Reader II(パーキンエルマー社)で、リン酸化されなかった基質ペプチド(S)とリン酸化されたペプチド(P)をマイクロ流路キャピラリー電気泳動によって分離・検出した。SとPそれぞれのピークの高さからリン酸化反応量を求め、リン酸化反応を50%抑制することのできる化合物濃度をIC50値(nM)と定義した。
結果を以下の表に示した。
HER2過剰発現ヒト胃癌細胞株であるNCI-N87細胞を、10%ウシ胎児血清を含むRPMI1640培地(ライフテクノロジーズ社製)中に懸濁させた。一方、EGFR過剰発現・高活性化ヒト類上皮がん細胞株であるA431細胞を、10%ウシ胎児血清を含むDMEM,high glucose培地(ライフテクノロジーズ社製)中に懸濁させた。次いで、それぞれの細胞懸濁液を、384ウェル平底マイクロプレートの各ウェルに播種し、5%炭酸ガス含有の培養器中37℃で1日培養した。合成例化合物をDMSOに溶解し、DMSOを用いて被検化合物を終濃度の500倍の濃度になるように希釈した。被検化合物のDMSO溶液を各細胞の懸濁に用いた培地で希釈し、これを細胞の培養プレートの各ウェルにDMSOの最終濃度が0.2%になるように加え、5%炭酸ガス含有の培養器中37℃でさらに3日培養した。化合物存在下で3日間培養後の細胞数計測はセルタイターグロ(プロメガ社製)を用いて、プロメガ社の推奨するプロトコールに基づき行った。以下の式より増殖阻害率を算出し、50%阻害する被検化合物の濃度(IC50(nM))を求めた。
結果を以下の表に示した。
増殖阻害率(%)=(C-T)/(C)×100
T:被検化合物を添加したウェルの発光強度
C:被検化合物を添加しなかったウェルの発光強度
また、一般式(I)で表されるピラゾロ[3,4-d]ピリミジン化合物は、EGFRキナーゼに比して優れたHER2キナーゼ阻害選択性を有することも明らかとなった。
HER2過剰発現ヒト乳癌細胞株であるSK-BR-3細胞は、10%ウシ胎児血清を含むMcCoy’s 5a培地(ライフテクノロジーズ社製)中に懸濁させた。細胞懸濁液を、384ウェル平底マイクロプレートの各ウェルに播種し、5%炭酸ガス含有の培養器中37℃で1日培養した。合成例化合物をDMSOに溶解し、DMSOを用いて被検化合物を終濃度の500倍の濃度になるように希釈した。被検化合物のDMSO溶液を各細胞の懸濁に用いた培地で希釈し、これを細胞の培養プレートの各ウェルにDMSOの最終濃度が0.2%になるように加え、5%炭酸ガス含有の培養器中37℃でさらに3日培養した。化合物存在下で3日間培養後の細胞数計測はセルタイターグロ(プロメガ社製)を用いて、プロメガ社の推奨するプロトコールに基づき行った。上記の式より増殖阻害率を算出し、50%阻害する被検化合物の濃度(IC50(nM))を求めた。
以下の実施例において、Compound 1は合成例化合物13の(R)-1-(1-アクリロイルピペリジン-3-イル)-4-アミノ-N-(4-(2-(ジメチルアミノ)-2-オキソエチル)-2,3-ジメチルフェニル)-1H-ピラゾロ[3,4-d]ピリミジン-3-カルボキサミドを示す。
ヒト胃癌細胞である4-1stは実験動物中央研究所よりフラグメント腫瘍として得た。ヌードマウス(BALB/cAJcl-nu/nu、日本クレア株式会社)の皮下にて移植継代後約1箇月の腫瘍を摘出し、約2mm角のフラグメントを作成した。フラグメント1個を移植針に詰め込み、ヌードマウスの右最後位肋骨付近から皮下に刺し、右背部まで進入させて内筒を押して腫瘍を押し出し移植した。腫瘍径の測定には電子ノギスを用い、1匹ずつ腫瘍の長径及び短径を電子ノギスの測定面で挟み測定した(Day0、4、8、11及び15)。この長径及び短径から腫瘍体積(tumor volume、TV)を算出した。算出した腫瘍体積から相対腫瘍体積(relative tumor volume、RTV)及び相対腫瘍体積変化率(T/C)を算出した。TV、RTV及びT/Cは以下の式より算出した。
腫瘍体積TV(mm3)=(長径、mm)×(短径、mm)×(短径、mm)/2
相対腫瘍体積RTV=(測定日のTV)/(群分け日のTV)
相対腫瘍体積変化率T/C(%)=(投与群の平均RTV)/(Control群の平均RTV)×100
また、体重の測定には動物用電子天秤を用いた。n日目の体重(BWn)からn日目体重変化率(BWCn)を以下の式により算出した。
体重変化率BWCn(%)=(BWn-BW0)/BW0×100
TVが100~300mm3になったヌードマウスを選別し、各群のTVの平均値が均等になるように等数法(MiSTAT(ver.2.0))により、各群6匹ずつの動物を割り付けた。Trastuzumab(ハーセプチン、Roche)は1日1回、Day1、8に尾静脈より投与した。Compound 1は1日1回、Day1-14に連日経口投与した。
併用効果および毒性の有無の判定は、群分け日(Day0)及び判定日(Day15)における腫瘍径および体重により実施した。なお、投与期間中は、投与液量算出のため、毎日体重を測定した。
結果を以下の表及び図1に示した。
Trastuzumabの代わりにTrastuzumab emtansine(カドサイラ、Roche)を用い、Trastuzumab emtansineを1日1回、Day1に尾静脈より投与した以外は、実施例1と同様の方法で実施した。
結果を以下の表及び図2に示した。
ヒト胃癌細胞株であるNCI-N87はAmerican Type Culture Collection(ATCC)から得た。10%ウシ胎仔血清(FBS)を含むRPMI-1640 (4.5g/L グルコース、10mM HEPES及び1mMピルビン酸ナトリウム含有)(和光純薬株式会社)培地において、5% CO2インキュベーター中において37℃で細胞株を培養した。
NCI-N87細胞をPBS中に8×107 cells/mLの濃度で再懸濁した。
1mLツベルクリン用シリンジと25Gの注射針を用いて、6週齢のヌードマウス(BALB/cAJcl-nu/nu、日本クレア株式会社)の右側胸部の皮下に8×106 cells/0.1 mLずつ細胞懸濁液を移植した。
腫瘍径の測定には電子ノギスを用い、腫瘍の長径及び短径を測定し、前述の式よりTV、RTV、T/Cを算出した。
また、体重の測定には動物用電子天秤を用いた。n日目の体重(BWn)からn日目体重変化率(BWCn)を前述の式により算出した。
TVが100~300mm3になったヌードマウスを選別し、各群のTVの平均値が均等になるように等数法(MiSTAT(ver.2.0))により、各群5匹ずつの動物を割り付けた。Capecitabine(ゼローダ、Roche)及びCompound 1は1日1回、Day1-14に連日経口投与した。
併用効果および毒性の有無の判定は、群分け日(Day0)及び判定日(Day15)における腫瘍径および体重により実施した。なお、投与期間中は、投与液量算出のため、毎日体重を測定した。
結果を以下の表及び図3,4に示した。
各試薬の入手元、腫瘍細胞株の入手元、使用培地、細胞播種数は以下の表に示した。
3日後にCellTiter-GloTM 2.0 Reagent(Promega Corporation)を25μL/ウェル添加し、化学発光をプレートリーダー(EnSpire(R) Multimode Plate Reader,PerkinElmer Japan Co., Ltd.)にて測定した。
得られたデータから各組み合わせの4ウェルの平均値を算出し、Vehicleを含む培地を添加したコントロールに対して標準化された細胞生存率を計算した。細胞生存率を1から減算することにより、Fa(Fraction of Affect)値を算出した。CIの算出には、Median Effect法を計算するメジアンエフェクト解析ソフトウェアCalcuSyn 2.0(CalcuSyn,Inc.)を用いた。
CIを算出するための両薬剤の濃度の組み合わせは、Fa値が1に近ければ一方の薬剤の効果が強すぎる濃度域、0に近ければいずれの薬剤の効果が弱すぎる濃度域と考えられ、相乗効果を議論するのに適当では無いため、Compound 1と他の抗腫瘍剤の各濃度の組み合わせによって算出されたFa値から、0.2≦Fa≦0.8となるような組み合わせを抽出した。
併用効果は以下の表の通りに判定した(Pharmacol Rev.,58(3),p.621-81,2006)。
