Description
本発明は、GSK3β阻害効果を有する化合物を組み合わせた脳腫瘍治療用キット及び脳腫瘍治療方法、並びにGSK3β阻害効果を有する化合物を含む抗癌剤に関する。 The present invention relates to a brain tumor treatment kit and a brain tumor treatment method in which a compound having a GSK3β inhibitory effect is combined, and an anticancer agent comprising a compound having a GSK3β inhibitory effect.
(グリコーゲン合成酵素キナーゼ3β)
グリコーゲン合成酵素キナーゼ3β(以下、「GSK3β」と記載する場合もある)は、Wnt/β−カテニンシグナル系の制御因子群(参照:非特許文献1、2)の1つであり、生理的条件下の細胞において、APCがん抑制タンパク質やアキシンなどから構成される複合体のなかでβ−カテニン(GSK3βの基質)をリン酸化して、ユビキチン分解系に誘導する。
(Glycogen synthase kinase 3β)
Glycogen synthase kinase 3β (hereinafter sometimes referred to as “GSK3β”) is one of the Wnt / β-catenin signal system regulator groups (refer to Non-Patent Documents 1 and 2) and physiological conditions. In the cells below, β-catenin (GSK3β substrate) is phosphorylated in a complex composed of APC tumor suppressor protein, axin, etc., and induced into the ubiquitin degradation system.
GSK3βは様々な細胞内シグナル伝達を媒介する多機能セリン・スレオニンキナーゼ(リン酸化酵素)であり、エネルギー代謝、転写調節、細胞増殖・生存等を含む広範な細胞調節過程を制御する(参照:非特許文献3−6)。つまり、Wnt/β−カテニンシグナルの制御は本酵素の多彩な機能の1つにすぎない。GSK3βは細胞内シグナル伝達を媒介する多くのタンパク質リン酸化酵素とは異なり、正常細胞において活性化型として存在し、種々の刺激によってその活性が抑制的に制御されている。GSK3βの基質には、c-Jun、c-Myc等の多様ながん化関連転写因子(参照:非特許文献7、8)や、β−カテニン、Gliタンパク質等の原がん遺伝子産物(参照:非特許文献9、10)が含まれ、これら基質の不活性化を介して細胞の腫瘍性形質転換や腫瘍発生を妨げることが想定されている。しかし、GSK3βのがん抑制効果、あるいはGSK3β阻害による発がん作用を証明する実験的根拠は報告されていない(参照:非特許文献11)。 GSK3β is a multifunctional serine / threonine kinase (phosphorase) that mediates a variety of intracellular signal transduction, and controls a wide range of cellular regulatory processes including energy metabolism, transcriptional regulation, cell growth / survival, etc. Patent Documents 3-6). In other words, the control of the Wnt / β-catenin signal is only one of the various functions of this enzyme. Unlike many protein kinases that mediate intracellular signal transduction, GSK3β exists as an activated form in normal cells, and its activity is suppressed by various stimuli. GSK3β substrates include various canceration-related transcription factors such as c-Jun and c-Myc (see Non-Patent Documents 7 and 8), and proto-oncogene products such as β-catenin and Gli protein (see : Non-Patent Documents 9 and 10), and it is assumed that tumor inactivation and tumor development of cells are prevented through inactivation of these substrates. However, no experimental evidence has been reported to prove the cancer-suppressing effect of GSK3β or the carcinogenic effect of GSK3β inhibition (see Non-Patent Document 11).
(GSK3βが関与する疾患)
GSK3βがインスリン非依存性糖尿病(2型糖尿病)やアルツハイマー病をはじめとする神経変性疾患の発症にも関与していることがわかってきた(参照:非特許文献12、13)。そのため、GSK3β阻害剤を神経変性疾患や2型糖尿病やがん等の治療に応用する特許出願もなされている(参照:特許文献1、2)。
(Diseases involving GSK3β)
It has been found that GSK3β is also involved in the development of neurodegenerative diseases such as non-insulin-dependent diabetes (type 2 diabetes) and Alzheimer's disease (see: Non-Patent Documents 12 and 13). Therefore, patent applications have been made in which GSK3β inhibitors are applied to the treatment of neurodegenerative diseases, type 2 diabetes, cancer, and the like (see: Patent Documents 1 and 2).
(脳腫瘍)
脳腫瘍(頭蓋内腫瘍)は、頭蓋内に発生する新生物のみならず、過誤腫や肉芽腫などの占拠性病変を含めた総称である。
一般には、(1)神経上皮組織から発生する神経膠腫、(2)神経鞘細胞から発生する腫瘍、(3)脳膜及び関連組織から発生する腫瘍、(4)悪性リンパ腫、(5)血管原性腫瘍、(6)胚細胞腫、(7)奇形腫様腫瘍(頭蓋咽頭腫など)と腫瘍様病変(過誤腫など)、(8)下垂体前葉腫瘍、(9)周辺組織の腫瘍の頭蓋内進展(褐色細胞腫や脊索腫など)及び(10)転移性脳腫瘍等に分類される。
(Brain tumor)
Brain tumors (intracranial tumors) are a generic term that includes not only neoplasms that develop within the skull but also occupying lesions such as hamartomas and granulomas.
In general, (1) gliomas arising from neuroepithelial tissues, (2) tumors arising from nerve sheath cells, (3) tumors arising from brain membranes and related tissues, (4) malignant lymphomas, (5) blood vessels Primary tumor, (6) germinoma, (7) teratomas-like tumor (craniopharyngioma, etc.) and tumor-like lesion (eg hamartoma), (8) anterior pituitary tumor, (9) tumor of surrounding tissue It is classified into intracranial extension (such as pheochromocytoma and chordoma) and (10) metastatic brain tumor.
(神経膠腫)
神経膠腫(glioma)は、髄上皮(medullary epithelium)から分化してくる細胞系(グリア細胞、神経細胞、松果体実質細胞)の細胞から発生する腫瘍(新生物)の総称である。
一般に、グリア細胞系の腫瘍としては星細胞腫瘍系、乏突起細胞腫系、上衣腫系及び膠芽腫であり、神経細胞系としては髄芽腫、髄様上皮腫、神経芽細胞腫、神経節性神経腫及び神経細胞神経膠腫であり、松果体実質細胞系としては松果体細胞腫及び松果体芽細胞腫である。
なお、悪性神経膠腫のうち退形成性星細胞腫の割合は約30%、膠芽腫の割合は約57%であり、合わせて約80%以上を占める。
(Glioma)
Glioma is a general term for tumors (neoplasms) that develop from cells of cell lines (glial cells, nerve cells, pineal parenchymal cells) that differentiate from the medullary epithelium.
In general, glial cell lineage tumors are astrocytic, oligodendroma, ependymoma, and glioblastoma, and neuronal cell lines are medulloblastoma, medullary epithelioma, neuroblastoma, neuroblastoma Nodular neuromas and neuronal gliomas, and pineal parenchymal cell lines are pineal cell tumor and pineal blastoma.
Of the malignant gliomas, the proportion of anaplastic astrocytoma is about 30%, and the proportion of glioblastoma is about 57%, which accounts for about 80% or more.
(膠芽腫)
膠芽腫(神経膠芽腫)は、原発性脳腫瘍の約9%を占め、神経膠腫の中でも最も分化度が低い悪性の腫瘍である(WHO grade IV)。成人の大脳半球に好発し、脳実質内にび慢性に浸潤増殖する。
標準的な治療方法は、開頭手術により新たな神経学的脱落症状を来たさない範囲で腫瘍を摘出する。そして、摘出手術後は放射線療法及び化学療法を行う。
しかし、上記治療を行っても、ほぼ100%の症例に再発を認め、平均生存期間は発症より約1年と、生命予後は極めて悪い。
これにより、膠芽腫の治療剤の開発要望が非常に高い。
(Glioblastoma)
Glioblastoma (glioblastoma) accounts for about 9% of primary brain tumors and is the least differentiated malignant tumor of glioma (WHO grade IV). It occurs frequently in the adult cerebral hemisphere and infiltrates and grows chronically in the brain parenchyma.
The standard treatment method is to remove the tumor as long as it does not cause new neurological dropout symptoms by craniotomy. And radiation therapy and chemotherapy are performed after an excision operation.
However, even with the above treatment, almost 100% of cases have relapsed, with an average survival time of about one year from the onset, and the prognosis is very poor.
Accordingly, there is a very high demand for development of a therapeutic agent for glioblastoma.

(GSK3β)
GSK3βは基本的な細胞生命現象を調節している多機能タンパク質リン酸化酵素である。そして、GSK3βの異常は2型糖尿病、神経変性疾患やがんなどの慢性進行性疾患の発症や経過に関わることが明らかにされてきた。
発明者らは、すでに、(1)消化器癌患者の癌組織や消化器癌細胞株で特異的なGSK3βの発現亢進が見られること、(2)GSK3β阻害剤の投与により用量依存的に消化器癌細胞株の生存と増殖が抑制されアポトーシスが誘導されること、(3)消化器癌細胞株の増殖がGSK3βに対するsiRNAによって抑制されることを見出し、(4)GSK3β阻害剤が抗癌剤として有用であること、(5)GSK3β抑制効果が抗癌剤評価の指標として有用であることを実証している(Shakoori A, et al. Biochem Biophys Res Commun 2005;334(4):1365-73; Shakoori A, et al. Cancer Sci 2007;98(9):1388-93; Mai W, et al. Clin Cancer Res 2009;15(22):6810-9参照)。
また、GSK3βにはヒトGSK3βのほか、マウスGSK3βなど、そのオーソログも含まれるが、本発明の目的においてはヒトGSK3βが最も好ましい。GSK3β遺伝子やGSK3βタンパク質の配列情報は公知であり、公共データベースであるGenBankより容易に入手することができる。例えば、マウスGSK3β遺伝子と対応するGSK3βタンパク質のアミノ酸配列は、Accession No. BC060743及びAAH60743.1、あるいはBC006936及びAAH06936.1として開示されている。また、ヒトGSK3β遺伝子と対応するGSK3βタンパク質のアミノ酸配列は、Accession No. NM_002093及びNP_002084として開示されている。もちろん、これらの配列は一例であって、GSK3β遺伝子やGSK3βタンパク質はこれら配列に限定されない。
(GSK3β)
GSK3β is a multifunctional protein kinase that regulates basic cellular life phenomena. GSK3β abnormalities have been shown to be associated with the onset and course of chronic progressive diseases such as type 2 diabetes, neurodegenerative diseases and cancer.
The inventors have already (1) specific GSK3β expression increased in cancer tissues and gastrointestinal cancer cell lines of digestive cancer patients, and (2) digestion in a dose-dependent manner by administration of GSK3β inhibitors. Survival and growth of organ cancer cell lines are suppressed and apoptosis is induced, (3) Growth of gastrointestinal cancer cell lines is found to be suppressed by siRNA against GSK3β, and (4) GSK3β inhibitors are useful as anticancer agents (5) It has been demonstrated that GSK3β inhibitory effect is useful as an index for anticancer drug evaluation (Shakoori A, et al. Biochem Biophys Res Commun 2005; 334 (4): 1365-73; Shakoori A, et al. Cancer Sci 2007; 98 (9): 1388-93; Mai W, et al. Clin Cancer Res 2009; 15 (22): 6810-9).
In addition to human GSK3β, GSK3β includes its orthologs such as mouse GSK3β. For the purposes of the present invention, human GSK3β is most preferred. The sequence information of GSK3β gene and GSK3β protein is known and can be easily obtained from GenBank, which is a public database. For example, the amino acid sequence of GSK3β protein corresponding to the mouse GSK3β gene is disclosed as Accession No. BC060743 and AAH60743.1, or BC006936 and AAH06936.1. The amino acid sequences of GSK3β proteins corresponding to the human GSK3β gene are disclosed as Accession Nos. NM_002093 and NP_002084. Of course, these sequences are merely examples, and the GSK3β gene and GSK3β protein are not limited to these sequences.
(GSK3β阻害剤)
本明細書において、GSK3β阻害剤とは、GSK3βの機能を物理的あるいは化学的に阻害する物質又は化合物を意味する。このようなGSK3β阻害剤については、既に多くの化合物が同定されているが、その構造と作用メカニズムは多岐にわたる(Meijer L, Flajolet M, Greengard P. Trends in Pharmacol Sci 2004;25(9):471-80参照)。
GSK3βの活性は種々の段階:(a)転写後修飾(転写後の第9セリンと第216チロシン残基のリン酸化による制御)、(b)タンパク複合体との相互作用、(c)基質プライミング、(d)細胞内局在、で制御されており、上記したGSK3β阻害剤はそのいずれかの段階でGSK3βに作用するものと思われる(Meijer L, Flajolet M, Greengard P. Trends Pharmacol Sci 2004;25(9):471-80参照)。
発明者らは、すでに、2つの代表的GSK3β阻害剤(AR-A014418及びSB-216763)について、これらが癌に対して特異的な抑制作用を有することを、in vitro及びin vivoの両実験系で実証した(Shakoori A, et al. Biochem Biophys Res Commun 2005;334(4):1365-73; Shakoori A, et al. Cancer Sci 2007;98(9):1388-93; Mai W, et al. Clin Cancer Res 2009;15(22):6810-9; 非特許文献14参照)。
また、これらのGSK3β阻害剤が、がん細胞において転写後修飾(リン酸化)を受けたGSK3βの活性を阻害しうることを確認した(Mai W, et al. Oncology 2006;71(3-4):297-305; Mai W, et al. Clin Cancer Res 2009;15(22):6810-9; 非特許文献14参照)。
(GSK3β inhibitor)
In the present specification, the GSK3β inhibitor means a substance or compound that physically or chemically inhibits the function of GSK3β. Many compounds have already been identified for such GSK3β inhibitors, but their structures and mechanisms of action are diverse (Meijer L, Flajolet M, Greengard P. Trends in Pharmacol Sci 2004; 25 (9): 471 -80).
The activity of GSK3β is in various stages: (a) post-transcriptional modification (regulation by phosphorylation of post-transcription 9th serine and 216 tyrosine residues), (b) interaction with protein complex, (c) substrate priming , (D) intracellular localization, and the GSK3β inhibitor described above seems to act on GSK3β at any stage (Meijer L, Flajolet M, Greengard P. Trends Pharmacol Sci 2004; 25 (9): 471-80).
The inventors have already demonstrated that two representative GSK3β inhibitors (AR-A014418 and SB-216763) have a specific inhibitory action against cancer, both in vitro and in vivo. (Shakoori A, et al. Biochem Biophys Res Commun 2005; 334 (4): 1365-73; Shakoori A, et al. Cancer Sci 2007; 98 (9): 1388-93; Mai W, et al. Clin Cancer Res 2009; 15 (22): 6810-9; see non-patent document 14).
It was also confirmed that these GSK3β inhibitors can inhibit the activity of GSK3β that has undergone post-transcriptional modification (phosphorylation) in cancer cells (Mai W, et al. Oncology 2006; 71 (3-4) : 297-305; Mai W, et al. Clin Cancer Res 2009; 15 (22): 6810-9;

The physiological activity of GSK3β is regulated by phosphorylation (9th serine residue, inactivated type; 216th tyrosine residue, activated type).
The present inventors have already described that "the expression and activity of GSK3β in colorectal cancer cells and tissues is enhanced irrespective of β-catenin activation (nuclear accumulation) and has been verified in non-cancer cells and tissues. The enzyme activity was not controlled by phosphorylation (inactivation) of serine residues, whereas GSK3β (activated) was phosphorylated on the 216th tyrosine residue specifically in cancer cells and cancer tissues. It was confirmed that the image was expressed frequently.
In addition, the present inventors have already shown that the enhancement of GSK3β activity, particularly the high expression of the 216th tyrosine residue phosphorylated GSK3β (activated) fraction, maintains and promotes the survival and proliferation of cancer cells. A new mechanism of promoting action has been confirmed.
That is, by inhibiting GSK3β activity activated by phosphorylation or activation of the 216th tyrosine residue by using pharmacological and transcriptional regulation techniques, cancer can be treated or prevented.
