Abstract
Description
本出願は2018年2月28日出願の米国仮特許出願第62/636,831号の恩典を主張するものであり、その全体が参照により本明細書に組み入れられる。
本発明は、米国国立衛生研究所(NIH)が授与した助成金番号R21NS084084に基づく政府支援により行った。米国政府は本発明において一定の権利を有する。
本発明は、がん化学療法の改善に関する。
細胞周期チェックポイントは、細胞周期事象の順序および忠実度をモニタリングおよび調整する監視機構である。細胞の分裂プログラムに欠陥が検出される際に、チェックポイントは関連サイクリン-cdk複合体の制御を通じて後続の細胞周期移行を防止する。DNA損傷に応答するチェックポイントが細胞周期のG1期、S期、およびG2期について記載されている。例えば、p53腫瘍抑制因子は、G1/Sチェックポイントの主要な制御因子であり、DNA損傷に応答して細胞周期遅延またはアポトーシスを促進しうる。複製前にDNA損傷を修復するために細胞周期を停止させる細胞の能力を損なう欠陥G1チェックポイントを有するがん細胞は、変異を蓄積し、かつ、がん形成に有利な変則性を伝播するための手段を備える。したがって、これらのがん細胞は、G2チェックポイントに依存して、分裂死によるアポトーシスをもたらす過度のDNA損傷を防止する(Chen T, et al. Drug Discovery Today. 2012;17(5-6):194-202(非特許文献1); Bucher N, et al., British Journal of Cancer.2008;98(3):523-8(非特許文献2))。正常細胞では、G1チェックポイントは損なわれず、したがって、G2チェックポイントには、DNA損傷修復の前に細胞周期を停止させることによる負荷がかからない。したがって、G2チェックポイントの調節は、正常細胞の増殖よりもむしろ腫瘍発生に選択的に影響する。
本開示の一局面は、式(I):

がんにおけるWEE1の役割
本発明者らは、小児脳腫瘍のパネルにおけるWEE1の発現を調査したところ、髄芽腫(medullo)、原始神経外胚葉性腫瘍(PNET)、および小児GBMを含む高悪性度腫瘍において、ならびに低悪性度毛様細胞性星細胞腫(PA)において、WEE1が正常脳に比べて過剰発現されることを発見した。これらのデータは、WEE1発現の増大が腫瘍発生に関与していることを裏づけている。
脳がんにおけるWEE1キナーゼの同定
髄芽腫治療の新規分子標的を同定するために、本発明者らは、腫瘍組織中での遺伝子発現のパスウェイ解析を使用する統合型ゲノムスクリーニング、およびDaoy髄芽腫細胞株中でのキノーム全体のsiRNAスクリーニングを行った。本発明者らは、Affymetrixマイクロアレイでの測定による、16個の髄芽腫試料および3個の正常小脳組織試料に関する遺伝子発現プロファイリングを行った(Int J Cancer.2012;131(8):1800-9)。IPAソフトウェア(Ingenuity)および遺伝子セット濃縮解析を使用してパスウェイ解析を行うことで、特異的シグナル伝達ネットワークを同定した。細胞周期関連遺伝子は分子カテゴリーに最も豊富に存在し、キナーゼは機能カテゴリーに最も豊富に存在した。髄芽腫における分子カテゴリーおよび機能カテゴリーと全制御不全遺伝子との比較により50個の特異的遺伝子が同定され、29個が髄芽腫中で正常小脳に比べて有意に過剰発現された。次に本発明者らは、キノーム全体のsiRNAスクリーニングを行って、髄芽腫細胞増殖に必須のキナーゼを同定した。髄芽腫Daoy細胞株に、710個の各キナーゼ遺伝子を標的とする2130個のsiRNA、または非サイレンシング対照を遺伝子導入した。
急性骨髄性白血病におけるWEE1の同定
WEE1は、S期停止を誘導する代謝拮抗剤であり、かつ急性骨髄性白血病(AML)治療成功の主要構成要素である、シタラビンでの処置後の、AML細胞生存のメディエーターとして同定された。シタラビンにWEE1阻害物質を追加することで、細胞周期チェックポイントが損なわれ、シタラビン単独の場合に比べていっそうアポトーシスが誘導される。これらのデータは、正常p53機能を有すると報告された細胞株中で作成された。
WEE1キナーゼ活性の阻害を判定するためのLanthaScreen TR-FRETアッセイ
LanthaScreen(商標)キナーゼ活性アッセイを行って、本開示の化合物のWEE1キナーゼ阻害活性を評価した。LanthaScreen Eu時間分解蛍光共鳴エネルギー移動(TR-FRET)キナーゼ結合アッセイ(Invitrogen)を、384ウェル低容量プレート(Corning)中で、組換えWEE1キナーゼ、キナーゼトレーサー178、およびLanthaScreen Eu抗GST抗体(Invitrogen)を使用して行った。段階希釈阻害物質溶液5μL、キナーゼトレーサー178溶液5μL、およびキナーゼ/抗体溶液5μLからなる反応混合物中、25℃でアッセイを行った。すべての試薬を1倍キナーゼ緩衝液A(Invitrogen)中溶液として最終所望濃度3倍で調製した。阻害物質溶液は最終DMSO濃度が0.5%を超えないように調製され、この濃度はキナーゼ活性に影響がないことが示された。阻害物質を最終濃度範囲0.04nM〜10μMでアッセイした。キナーゼトレーサー178を最終濃度150nMで使用し、抗体およびキナーゼをそれぞれ最終濃度3nMおよび5nMで使用した。すべての試薬を一緒に室温で1時間インキュベートし、TR-FRETで使用可能になったPerkinElmer Envision 2104マルチラベルリーダー(励起 = 340nm; トレーサー発光 = 665nm; 抗体発光 = 615nm; 遅延 = 100μs; 積分 = 200μs)を使用して読み取った。発光比(665nm/615nm)を各阻害物質濃度について測定し、データを対数用量反応曲線の非線形回帰分析を用いて解析してIC50値を測定した。
髄芽腫細胞中での細胞生存率に対するWEE1阻害物質の効果
WEE1キナーゼ阻害物質の効果を評価するために、Daoy細胞およびONS-76細胞(ヒト初代髄芽腫細胞株)を試験化合物で処理し、細胞増殖をMTSアッセイにより測定した(図1Aおよび図1B)。Daoy細胞およびONS-76細胞を滅菌96ウェルプレート(Corning Inc.)中に、培地100μL中、細胞2000個/ウェルで播種した。阻害物質をAZD1775のMTS EC50(Daoy; EC50 = 150nM、ONS-76; EC50 = 290nM)ならびにEC50を超える濃度およびEC50未満の濃度で投与した。細胞を各希釈薬物溶液50μLと共に72時間インキュベートした。細胞生存率をCellTiter 96(登録商標)AQueous One細胞増殖試薬(Promega)30μLとの2時間のインキュベーションにより測定し、ホルマザン濃度をBioTek Synergy H1プレートリーダーを使用する比色分析(吸収 = 490nm)を通じて評価した。試験化合物の平均IC50値、または細胞阻害パーセントを以下の表に列挙する。
ND = 未決定。調査期間中、濃度範囲にわたる細胞生存率の有意な減少はなかった。
DAOY細胞中でのWEE1キナーゼ活性の阻害を判定するためのCDK ELISA
WEE1は、CDC2-サイクリンB複合体を安定化するサイクリン依存性キナーゼ1(CDK1)のTyr15残基の選択的リン酸化を通じてCDC2を不活性化する。したがって、WEE1キナーゼ活性の阻害は、Tyr15におけるその基質CDK1のリン酸化を防止すると考えられる。定量的解析では、ELISAアッセイを用いて、単一濃度での(220nM; 図2A)および濃度範囲にわたる(図2B)本開示のWEE1阻害物質による処置後のDaoy細胞溶解液中でのpCDK1(Tyr15)の相対レベルを測定した。Daoy細胞を滅菌6ウェルプレートに細胞200,000個/ウェルでプレーティングし、用量220nMの活性阻害物質で処理し、24時間インキュベートした後、細胞溶解液を調製した。DMSO対照と比較した際に、この濃度で細胞p-CDK1レベルを阻害することがわかったあらゆる化合物を、1000μM〜62.5μMの濃度範囲にわたって試験した。薬物インキュベーション後に、培地を細胞から吸引し、次に細胞をトリプシン処理し、プロテアーゼ阻害物質を含むTES/SB緩衝液に再懸濁させた。細胞を氷上で超音波処理を通じて溶解させ、使用前に細胞溶解液をELISA Pathscan(登録商標)試料希釈液で最終量100μLおよびタンパク質濃度0.05mg/mlに希釈した。p-CDK1 Tyr15の相対濃度を、推奨プロトコールによる酵素結合免疫吸着測定法(Cell Signaling、ELISA Pathscan(登録商標)ホスホCdc2(Tyr15))を使用して測定した。
阻害物質の合成
tert-ブチル(1,3-ジオキソイソインドリン-2-イル)カルバメートの合成。無水フタル酸(10.0g、67.5mmol)の還流トルエン(110ml)溶液にカルバジン酸tert-ブチル(9.40g、70.9mmol)を数回に分けて加えた。得られた懸濁液を還流条件下で18時間加熱した後、冷却し、析出物を濾去した。濾液をヘキサンで洗浄し、減圧乾燥させて所望の生成物を白色結晶性固体(16.1g、61.4mmol、91%)として得た。
