Description

悪性リンパ腫治療剤Malignant lymphoma treatment
 本発明は、アミノピラジン誘導体を有効成分として含有する悪性リンパ腫治療剤又は予防剤に関するものである。 The present invention relates to a therapeutic or preventive agent for malignant lymphoma containing an aminopyrazine derivative as an active ingredient.
 JAK2チロシンキナーゼ(以下、JAK2ともいう)はJAK/STAT経路を始めとした種々の細胞内シグナル経路を活性化することで細胞の増殖及び生存、抗アポトーシスに関与する。JAK2は多くの固形癌及び血液がん(例えば、真性多血症、本態性血小板血症)の発症及び進展に関与することが知られているが、悪性リンパ腫においてもJAK2の関与が示唆されている。例えばホジキンリンパ腫、B細胞リンパ腫(例えば、縦隔大細胞型B細胞リンパ腫)、NK/T細胞リンパ腫(例えば、血管免疫芽球性T細胞リンパ腫、ALK陽性未分化大細胞型リンパ腫)において、JAK2の変異若しくは転座に基づくJAK2の活性化が認められている(例えば、非特許文献1参照。)。また、同時に、ホジキンリンパ腫、B細胞リンパ腫(例えば、縦隔大細胞型B細胞リンパ腫、びまん性大細胞性リンパ腫、濾胞性リンパ腫、マントル細胞リンパ腫、バーキットリンパ腫)において、JAK2の抑制因子であるSOCS1(サイトカインシグナル抑制因子1)の不活性化によるJAK2の活性化が確認されている(例えば、非特許文献2,3,4参照。)。このように、ホジキンリンパ腫、B細胞リンパ腫、T細胞リンパ腫において複数のメカニズムによるJAK2の活性化が確認されていることから、JAK2活性化が異常なリンパ球の増殖を引き起こすと考えられる。
 また現在、JAK2阻害剤であるSB1518については、再発難治性を含むホジキン、非ホジキンリンパ腫の治療剤として、臨床試験が開始されている(例えば、非特許文献5、6参照。)。
 以上より、JAK2阻害剤は効率的に悪性リンパ腫患者のリンパ球の異常増殖を抑えることができると考えられ、新規な分子標的薬として有望である。
 一方、真性多血症及び本態性血小板血症の一部は、骨髄線維症に転化することが知られており、真性多血症から続発した続発性骨髄線維症の患者、及び、本態性血小板血症から続発した続発性骨髄線維症の患者のJAK2遺伝子に変異が生じていることが報告されている(例えば、非特許文献7、8参照。)。
 更に、一部の患者においては、真性多血症、本態性血小板血症、又は、骨髄線維症が急性骨髄性白血病に転化することも報告されており、真性多血症から続発した急性骨髄性白血病の患者、本態性血小板血症から続発した急性骨髄性白血病の患者、及び、骨髄線維症から続発した急性骨髄性白血病の患者のJAK2遺伝子に変異が生じていることも報告されている(例えば、非特許文献7、8参照。)。
 従って、JAK2阻害剤はこれらの続発性骨髄線維症、及び、続発性急性骨髄性白血病の治療剤としても有用である。
JAK2 tyrosine kinase (hereinafter also referred to as JAK2) is involved in cell proliferation and survival and anti-apoptosis by activating various intracellular signal pathways including the JAK / STAT pathway. JAK2 is known to be involved in the development and development of many solid cancers and blood cancers (eg, polycythemia vera, essential thrombocythemia), but it is suggested that JAK2 is also involved in malignant lymphoma Yes. For example, in Hodgkin lymphoma, B cell lymphoma (eg, mediastinal large B cell lymphoma), NK / T cell lymphoma (eg, hemangioblastic T cell lymphoma, ALK positive anaplastic large cell lymphoma) Activation of JAK2 based on mutation or translocation is recognized (for example, refer nonpatent literature 1). At the same time, SOCS1 which is a suppressor of JAK2 in Hodgkin lymphoma and B cell lymphoma (for example, mediastinal large cell B cell lymphoma, diffuse large cell lymphoma, follicular lymphoma, mantle cell lymphoma, Burkitt lymphoma) Activation of JAK2 due to inactivation of (cytokine signal inhibitory factor 1) has been confirmed (see, for example, Non-Patent Documents 2, 3, and 4). Thus, since activation of JAK2 by several mechanisms has been confirmed in Hodgkin lymphoma, B cell lymphoma, and T cell lymphoma, JAK2 activation is considered to cause abnormal lymphocyte proliferation.
Currently, SB1518, which is a JAK2 inhibitor, has started clinical trials as a therapeutic agent for Hodgkin and non-Hodgkin's lymphoma that are refractory to relapse (see, for example, Non-Patent Documents 5 and 6).
As mentioned above, it is thought that a JAK2 inhibitor can suppress the abnormal proliferation of the lymphocyte of a malignant lymphoma patient efficiently, and is promising as a novel molecular target drug.
On the other hand, it is known that some of polycythemia vera and essential thrombocythemia are converted to myelofibrosis. Patients with secondary myelofibrosis secondary to polycythemia vera and essential platelets It has been reported that a mutation has occurred in the JAK2 gene of a patient with secondary myelofibrosis secondary to blood glucose (see, for example, Non-Patent Documents 7 and 8).
Furthermore, in some patients, it has been reported that polycythemia vera, essential thrombocythemia, or myelofibrosis is converted to acute myeloid leukemia, and acute myeloid disease secondary to polycythemia vera It has also been reported that mutations have occurred in the JAK2 gene in patients with leukemia, patients with acute myeloid leukemia secondary to essential thrombocythemia, and patients with acute myeloid leukemia secondary to myelofibrosis (eg, Non-Patent Documents 7 and 8).
Therefore, a JAK2 inhibitor is useful as a therapeutic agent for these secondary myelofibrosis and secondary acute myeloid leukemia.

Further, a solution diluted 20 times with assay buffer was used as a test substance solution. As a negative control, a solution obtained by diluting DMSO 20 times with assay buffer was used. As the assay buffer, 15 mM Tris-Cl (pH 7.5), 0.01 (v / v)% Tween-20, 1 mM dithiothreitol was used.

2. Measurement of JAK2 and JAK3 tyrosine kinase activity ELISA was used to measure the activity.

Finally, 20 μL of JAK2 tyrosine kinase (Karna Biosciences) (diluted to 0.75 nM in assay buffer) or JAK3 tyrosine kinase (Karna Biosciences) (diluted to 0.75 nM in assay buffer) was added and stirred. And reacted at 30 ° C. for 1 hour. The plate was washed 4 times with wash buffer (50 mM Tris-Cl, pH 7.5, 150 mM NaCl, 0.02 (v / v)% Tween-20), then blocking buffer (0.1% Bovine Serum Albumin, 50 mM Tris, 50 mM Tris). -Cl, pH 7.5, 150 mM NaCl, 0.02 (v / v)% Tween-20) was added in an amount of 150 μL, and blocking was performed at 30 ° C. for 30 minutes. The blocking buffer was removed, and Horse Radish Peroxidase-labeled anti-phosphotyrosine antibody (BD Bioscience) (diluted 10,000-fold with blocking buffer) was added in an amount of 100 μL and incubated at 30 ° C. for 30 minutes. The plate was washed four times with a washing buffer, and 100 μL of 3,3 ′, 5,5′-tetramethylbenzidine solution (Sigma-Aldrich) was added to develop the color for 10 minutes. The reaction was stopped by adding 100 μL of 0.1 M sulfuric acid. Absorbance at 450 nm was measured with a microplate reader (BIO-RAD, Model 3550).

3. Analysis of Measurement Results The measured absorbance was subjected to nonlinear regression analysis using a SAS system (SAS Institute Inc.), and the concentration (IC 50 ) of the test substance that inhibits each tyrosine kinase activity by 50% was calculated. The results are shown in Tables 13 to 18.

The test substance solution was added to each well in triplicate.
After culturing for 3 days, the number of viable cells was counted by the MTT method. The MTT method was performed as follows. First, 10 μL of 5 mg / mL MTT (3- (4,5-Dimethylthiazol-2-yl) -2,5-diphenyltetrazolium bromide) solution was added to each well. After standing for 4 hours in a CO 2 incubator, 100 μL of 2-propanol solution containing 0.04N hydrochloric acid was added to each well to stop the reaction. The produced MTT formazan was sufficiently dissolved with a multi-channel pipette, and the absorbance at 595 nm (Thermo's Multiskan FC) was measured using 655 nm as a control. Nonlinear regression analysis was performed using a SAS system (SAS Institute Inc.), and the concentration of the test substance that inhibits cell growth by 50% (IC 50 ) was calculated. The results are shown in Table 19.
