Abstract
Description
本発明は、Pimキナーゼ阻害(以下、Pim阻害という)作用を有し、抗がん剤等の医薬として有用な化合物及びそれを含有する医薬に関する。 The present invention relates to a compound having Pim kinase inhibition (hereinafter referred to as Pim inhibition) and useful as a medicament such as an anticancer agent, and a medicament containing the same.
プロテインキナーゼは、細胞内や細胞間での情報伝達の制御に重要な役割を果たしており、がんをはじめとする様々な疾患に関与している。近年では、上皮細胞増殖因子受容体(EGFR)チロシンキナーゼ阻害剤のゲフィチニブやエルロチニブ、Bcr-Ablチロシンキナーゼ阻害剤のイマチニブや、多種類のプロテインキナーゼを阻害するソラフェニブなど、プロテインキナーゼを標的とした阻害剤が分子標的治療薬としてがんの治療分野で広く臨床使用されており、高い有効性が示されている。ヒトのプロテインキナーゼは500種類以上あるとも言われており、今後も新しいがん分子標的治療薬の開発を目的としたターゲットとして大きな可能性を秘めているものと考えられる。 Protein kinases play an important role in the control of information transmission within and between cells and are involved in various diseases including cancer. In recent years, protein kinase targeting inhibitors such as epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors gefitinib and erlotinib, Bcr-Abl tyrosine kinase inhibitor imatinib, and sorafenib that inhibits many types of protein kinases The drug is widely used clinically in the field of cancer treatment as a molecular targeted therapeutic agent, and has shown high effectiveness. It is said that there are more than 500 types of human protein kinases, and it is believed that they have great potential as targets for the development of new cancer molecular targeted therapeutics.
Pim-1は、細胞周期の進行やアポトーシスを制御する種々の細胞内因子をリン酸化することにより、細胞の生存や増殖を正に制御するセリン・スレオニンキナーゼである。例えば、Pim-1は、アポトーシス促進因子であるBADをリン酸化することにより不活性化し、抗アポトーシス因子として働くことが知られている。また、Pim-1は、細胞周期の進行を正に制御するCDC25AやCDC25Cをリン酸化することによりホスファターゼ活性を上昇させるとともに、細胞周期の進行を負に制御するp21をリン酸化することにより不活性化させて、細胞周期の進行を加速させることが報告されている。さらにPim-1は、蛋白質の合成制御因子である4E-BP1をリン酸化することにより蛋白合成を増加させ、細胞の増殖を促進させることが知られている。Pim-1には、相同性の高いPim-2とPim-3の2種類のアイソザイムが知られているが、これらについてもPim-1と同様に、上記の機能を部分的に共有していると考えられている。 Pim-1 is a serine / threonine kinase that positively controls cell survival and proliferation by phosphorylating various intracellular factors that control cell cycle progression and apoptosis. For example, Pim-1 is known to be inactivated by phosphorylating BAD, which is a proapoptotic factor, and to act as an anti-apoptotic factor. In addition, Pim-1 increases phosphatase activity by phosphorylating CDC25A and CDC25C that positively control cell cycle progression, and inactive by phosphorylating p21 that negatively regulates cell cycle progression. To accelerate cell cycle progression. Furthermore, Pim-1 is known to increase protein synthesis and promote cell growth by phosphorylating 4E-BP1, which is a protein synthesis regulator. Pim-1 is known to have two types of isozymes, Pim-2 and Pim-3, which are highly homologous, and, like Pim-1, also partially share the above functions. It is believed that.
以上のように、Pim-1、Pim-2およびPim-3は、細胞の生存や増殖に関わる様々な因子の活性制御に関与しており、がんなどの細胞の異常増殖を特徴とする疾患に深く関与していると考えられている。実際に、Pimは、急性骨髄性白血病をはじめとする血液がんや、前立腺がんをはじめとする固形がんなど、種々のがんの進展に関与していることが報告されている(非特許文献1~5)。また、血管新生(非特許文献6)や化学療法における抗がん剤に対する耐性(非特許文献7)にも関与することが示唆されており、Pimはがん治療において魅力的な分子標的と考えられ、それを阻害する化合物は新しいがんの治療薬として期待される。さらに、Pimの関与はがん以外の領域にも及んでいる。例えば、Pimは、炎症性サイトカインの作用を増強させるとともに、産生量を増加させることが報告されており(非特許文献8)、関節リウマチなどの炎症性疾患の治療を目的とした分子標的になり得ると考えられる。
これまでに幾つかのPim阻害剤が報告されている(非特許文献9~12)。
As described above, Pim-1, Pim-2 and Pim-3 are involved in the control of the activity of various factors involved in cell survival and proliferation, and diseases characterized by abnormal cell proliferation such as cancer Is thought to be deeply involved in In fact, Pim has been reported to be involved in the development of various cancers such as hematological cancers including acute myeloid leukemia, and solid cancers including prostate cancer.

細胞内のDNA断片化を指標に、本発明化合物のがん細胞に対するアポトーシス誘導作用をin vitroにて評価した。なお、本実験では、Pim阻害作用を有することが知られているSGI-1776と、アポトーシスを誘導することが知られているトポイソメラーゼ1阻害剤のSN-38を陽性対照薬として用いた。ヒト大腸がんHCT116細胞を1%FBS/RPMI1640に浮遊させ、96ウェルプレートに播種して5%CO2、37℃にて3時間培養後、DMSOに溶解した被験化合物を1%FBS/RPMI1640で希釈して加え、さらに48時間培養した。培養後、Cell Death Detection ELISA PLUS(Roche)を使用して、添付の操作手順に従って細胞内のDNA断片量を測定した。なお、コントロールは被験化合物を含まない条件で測定した。結果は、コントロールにおけるDNA断片量を1とした相対量(Fold)で表した。その結果、図4に示すように、本発明の化合物は、細胞増殖抑制作用を示す濃度において、DNAの断片化を誘導した。この結果から、本発明の化合物がアポトーシス誘導作用を発揮することが示唆された。

ヒト急性骨髄性白血病MV-4-11細胞移植マウスにおける抗腫瘍効果
本発明化合物のin vivoにおける抗腫瘍効果についてヒト急性骨髄性白血病MV-4-11細胞移植マウスを用いて検討した。雄性、6週齡のBALB/c系マウスの鼠径部皮下にMV-4-11細胞を移植後(5x106cells/mouse)、1/2ab2(aは腫瘍の長径、bは短径)より求めた推定腫瘍体積が約100mm3に達した時点(1日目)より2日に1回3週間、5%グルコースに溶解した本発明の化合物を静脈内(i.v.)または経口(p.o.)投与した。また、コントロールは本発明の化合物の非投与群とした。22日目に腫瘍を摘出して重量を測定した後、次式により腫瘍増殖阻止率IR(%)を求めた。
腫瘍増殖阻止率IR(%)
=(1-投与群の腫瘍重量/非投与対照群の腫瘍重量)×100
その結果、表9に示すように、本発明の化合物はin vivoにおいて抗腫瘍効果を発揮することが示された。

Antitumor effect in mice transplanted with human acute myeloid leukemia MV-4-11 cells The in vivo antitumor effect of the compound of the present invention was examined using mice transplanted with human acute myeloid leukemia MV-4-11 cells. Male, after implantation the MV-4-11 cells groin subcutaneously BALB / c mice of 6 weeks old (5x10 6 cells / mouse), 1 / 2ab 2 (a major axis of the tumor, b is the minor axis) than The compound of the present invention dissolved in 5% glucose is administered intravenously (iv) or orally (p) once every two days for 3 weeks once the estimated tumor volume obtained reaches about 100 mm 3 (Day 1). O.) Administration. The control was a non-administration group of the compound of the present invention. On the 22nd day, the tumor was excised and weighed, and then the tumor growth inhibition rate IR (%) was determined by the following formula.
Tumor growth inhibition rate IR (%)
= (1-tumor weight of administration group / tumor weight of non-administration control group) × 100
As a result, as shown in Table 9, it was shown that the compound of the present invention exerts an antitumor effect in vivo.
