Definitions

  • the invention belongs to the field of chemistry and medicine, and specifically relates to 2,4-disubstituted pyrimidine derivatives, and preparation methods and uses thereof.
  • it relates to the application of a 2,4-disubstituted pyrimidine derivative as an inhibitor of Janus tyrosine kinase 2 and FMS-like tyrosine kinase 3 (JAK2-FLT3).
  • MPNs Myeloproliferative neoplasms
  • pluripotent hematopoietic stem cells which are manifested by the excessive proliferation of one or more lines of myeloid cells, and the increase in one or more lines of peripheral blood.
  • thrombus thrombus, extramedullary hematopoiesis, bone marrow fibrosis and transform into acute leukemia.
  • diseases include polycythaemia vera (PV), primary thrombocytosis (PT) and primary myelofibrosis (PMF).
  • JAK2 kinase in the Janus kinase (JAK) family plays an important role in MPNs.
  • JAK-signal converter and activator of transcription (JAK-STAT) pathways control the survival, proliferation and differentiation of various cells through cytokine-mediated signal transmission.
  • JAK-STAT JAK-signal converter and activator of transcription
  • the phosphorylation of JAK2, phosphorylation of downstream STAT, and activation of gene transcription will eventually lead to the increase of red blood cell and myeloid cell proliferation, differentiation and survival.
  • JAK2 inhibitors There are a variety of JAK2 inhibitors in clinical trials.
  • Ruxolitinib has been approved by the FDA for myelofibrosis, and the others such as Lestaurtinib (CEP701), CYT-387, LY2784544, BMS-911543, etc. are still undergoing clinical trials .
  • FMS-like tyrosine kinase 3 (FLT3) mutations are also closely related to MPNs: ITD (internal tandem repeat) mutations knocked into mouse FLT3 can cause mice to develop myeloproliferative diseases.
  • FLT3 is a receptor tyrosine kinase that plays a vital role in the development of hematopoietic progenitor cells.
  • AML acute myeloid leukemia
  • ITD internal tandem repeat
  • Small molecule FLT3 inhibitors have been in clinical trials as single drugs or combination chemotherapy.
  • JAK2/FLT3 dual-target inhibitors for the treatment of MPNs have gradually become a research and development hotspot.
  • the JAK2/FLT3 dual-target inhibitor Fedratinib has been approved by the FDA for priority use in myelofibrosis, and the macrocyclic structure compound Pacritinib is also undergoing clinical trials. Phase III study (for the treatment of myelofibrosis).
  • the existing JAK2/FLT3 dual-target inhibitors have poor enzymatic activity, low oral bioavailability, and still cannot meet medical needs. Therefore, they have developed better selectivity, higher activity, and better in vivo pharmacokinetics.
  • Property inhibitors are currently a hot spot in research and development.

Description

2,4-二取代嘧啶衍生物及其制备方法和用途 技术领域
本发明属于化学医药领域,具体涉及2,4-二取代嘧啶衍生物及其制备方法和用途。特别是涉及一种2,4-二取代嘧啶衍生物作为贾纳斯酪氨酸激酶2以及FMS样的酪氨酸激酶3(JAK2-FLT3)抑制剂的应用。
背景技术
骨髓增殖性肿瘤(myeloproliferative neoplasms,MPNs)是一组起源于多能造血干细胞的恶性骨髓增殖性疾病,表现为髓系细胞一系或多系的过度增殖,进而外周血一系或多系增多,有形成血栓、髓外造血、骨髓纤维化及转化为急性白血病的趋势。这类疾病包括真性红细胞增多症(polycythaemia vera,PV)、原发性血小板增多症(primary thrombocytosis,PT)和原发性骨髓纤维化(primary myelofibrosis,PMF)。
目前的临床治疗方法仍不能治愈MPNs类疾病。近年来的研究发现,贾纳斯激酶(JAK)家族中的JAK2激酶在MPNs中起着重要作用。JAK-信号转换器和转录激活因子(JAK-STAT)通路通过细胞因子介导信号传递,控制多种细胞的存活、增殖和分化。而JAK2磷酸化、下游STAT磷酸化以及基因转录的激活会最终导致红细胞和髓细胞增殖、分化和存活的增加。现已有多种JAK2抑制剂在进行临床试验,其中JAK2抑制剂Ruxolitinib已被FDA批准用于骨髓纤维化,其余如Lestaurtinib(CEP701),CYT-387,LY2784544,BMS-911543等仍在进行临床研究。
此外,最新的研究表明,FMS样酪氨酸激酶3(FLT3)突变也与MPNs息息相关:ITD(内部串联重复)突变敲入小鼠FLT3后,可导致小鼠产生骨髓增生性疾病。FLT3是一种受体酪氨酸激酶,它在造血祖细胞的发育过程中起着至关重要的作用。急性髓细胞白血病(AML)患者中约有30%发现激活的FLT3内串联重复(ITD)突变,而这是导致疾病复发的高危因素。小分子FLT3抑制剂已经作为单一药物或者组合化疗在进行临床试验,然而到目前为止,这些候选药物要么没有产生足够的初始反应,要么不能维持治疗效益,其原因主要是由于继发性的耐药性。临床资料也表明病人治疗后外周血白血病细胞急剧下降,但骨髓反应却几乎没有,这些失败的可能机制之一是可能存在独立的替代生存途径,白血病细胞可以通过进一步的遗传突变或代谢适应。这些途径可能包括mTOR-PI3K-Akt,JAK-STAT或Ras-MAPK。同时抑制这些途径可能将使白血病细胞摆脱FLT3的限制。
在这基础上,同时靶向JAK2通路则有以下几个优点:(a)AML病例中几乎没有发现JAK2突变,(b)在AML中发现磷酸化-JAK2升高,(c)在FLT3-TKI耐药株FLT3-ITD中,JAK信号的负调节器即细胞因子1/2/3的抑制物会被显著下调。同时,有证据表明,抑制JAK2-FLT3两个信号通路可以增强具有FLT3-ITD突变的AML患者的临床疗效。 基于此,JAK2/FLT3双靶点抑制剂治疗MPNs也逐渐成为研发热点,目前已有JAK2/FLT3双靶点抑制剂Fedratinib被FDA批准优先用于骨髓纤维化,大环结构化合物Pacritinib也在进行临床三期研究(用于治疗骨髓纤维化)。然而,现有的JAK2/FLT3双靶点抑制剂酶活性较差,口服生物利用度不高,仍不能满足医疗需求,因此,开发出选择性更好、活性更高、具有更好体内药代属性的抑制剂是目前研发的热点。

药理活性实验
以下代表性实验(不限于此)用于分析本发明化合物的生物活性
MTT法测细胞增殖抑制实验
测试本发明受试化合物对癌细胞活力的影响,在MV4-11、MOLM-13、SET-2上进行,MV4-11和MOLM-13为人白血病细胞系,来自美国典型培养物中心(American Type Culture Collection,ATCC),表达FLT3受体,并包含FLT3-ITD突变;SET-2为原发性血小板增多症细胞,购自中国成都博威士顿生物科技有限公司,持续表达JAK2受体,并包含V617F突变。
MV4-11、MOLM-13和SET-2细胞装于96孔培养皿中,介质为100μL IMDM,包含10%胎牛血清(购于草原绿野生物公司,100mL/瓶,-20℃密闭冻存),每孔有10000-15000个细胞,受试化合物在100%DMSO(二甲基亚砜)中制备,加入到细胞中,获得浓度为100nM到0.032nM(按照5倍稀释浓度的6个浓度点),空白对照组每孔加入100μL新鲜培养基,溶剂对照组每孔加入等体积含与药物最高实验浓度等量DMSO的新鲜培养基,每组设置3-5个平行孔,在37℃5%CO 2中培养72h。在终点时,向每个孔中加入20μLMTT(5mg/mL),并将细胞再孵育1-3小时。用20%SDS处理过夜后,在分光光度计(Molecular Devices,Sunnyvale,USA)上获得波长570nM的吸光度OD值。
按抑制率=[(溶剂对照组平均OD值-实验组平均OD值)/(溶剂对照组平均OD值–空白对照组平均OD值)]×100%,计算各实验组抑制率。
计算出各浓度化合物对细胞增殖活性的抑制率后,将化合物处理浓度与其对应的抑 制率用Graphpad prism软件拟合剂量-响应曲线,并拟合IC 50值。测定结果见表1。
体外激酶活性测定实验
在一个反应管内,依次加入缓冲液(8mM MOPS,pH 7.0,0.2mM EDTA,10mM MnCl 2),待测激酶、待测激酶的底物,10mM醋酸镁和γ33P-ATP溶液,以及不同浓度的化合物,然后向反应中加入MgATP以启动酶反应过程,并在室温下孵育40分钟。最终用5微升的3%磷酸盐缓冲液终止反应,并把10微升的反应液滴定到FiltermatA膜上,用75mM的磷酸盐溶液洗三次,每次5分钟,再用甲醇洗一次,最后干燥Filtermat A膜并对其进行闪烁计数,闪烁计数值的大小反映了底物被磷酸化的程度,从而可以表征激酶活性抑制情况。@500nM表明在500nM水平对酶的抑制率(%),数据由Eurofins公司测得。测定结果见表1。

结果表明,本发明的大部分受试化合物对MV4-11、MOLM-13和SET-2细胞增殖具有较好的抑制活性,同时对JAK2和FLT3也具有较好的抑制活性,是一种新型的、潜在的和具备治疗JAK2-FLT3-ITD相关疾病潜力的抑制剂。
表2本发明优选化合物对JAK1/2/3和FLT3激酶抑制剂活性
Figure PCTCN2020098523-appb-000320
结果表明,本发明多个优选化合物具有较好的体外酶学抑制活性,以及良好的选择性。
我们选用优选化合物CLJ-44为代表进行JAK2/FLT3信号通路相关蛋白进行免疫印迹实验,实验选择FLT3高表达的MV4-11细胞以及JAK2高表达细胞SET-2进行。不同浓度的CLJ-44处理细胞后,收集细胞,让蛋白样品失活并充分裂解。用8%-16%梯度胶进行SDS-PAGE凝胶电泳后,进行恒流转膜。用5%脱脂牛奶封闭后,4℃孵育一抗FLT3(CST,3462S),p-FLT3(CST,3464S),STAT5(CST,9363S),p-STAT5(Abcam,ab32364),JAK2(Proteintech,02802),p-JAK2(Abcam,ab32101),JAK1(Santa Cruz Biotechnology,sc-136225),p-JAK1(Santa Cruz Biotechnology,sc-101716),GAPDH(Abways,AB0037),Rb(Abways,CY5661),p-Rb(Abways,CY5260)。次日用PBS/T洗涤3次,而后室温孵育二抗辣根酶标记山羊抗小鼠二抗(Abways,AB0102),辣根酶标记山羊抗兔二抗(Abways,AB0101),再用洗涤PBS/T洗涤3次后加入ECL化学发光底物显影。结果表明,优选化合物能够明显抑制JAK2/FLT3的自身磷酸化,并且表现出剂量依赖关系,对通路相关蛋白如STAT5,也表现出相同的作用。对JAK亚型JAK1,则表现出较弱的作用,与激酶结果一致,说明了该优选化合物的良好选择性。
结合优选化合物良好的药代动力学参数以及极好的细胞和酶活性,我们选用CLJ-44进行动物实验。我们用MV4-11细胞和SET-2细胞建立小鼠异种移植瘤模型来考察其药效。NOD/SCID免疫缺陷小鼠(购于北京华阜康生物科技股份有限公司)接收后适应环 境,饮食活动均正常后,常规培养MV4-11和SET-2细胞,当生长至80%融合度时,收集细胞,血球计数板进行细胞计数,调整细胞浓度到3×10 7个/mL,细胞收集完成后,取100μL细胞悬液于小鼠背部皮下注射接种。当肿瘤体积到达100mm 3时,开始给药。给药方案采用口服每天给药,由结果可知,60mg/kg给药时,CLJ-44在MV4-11模型上抑瘤率达到93%,60mg/kg给药时,在SET-2模型上抑瘤率达到85%。综上所述,CLJ-44具有良好体内抑制肿瘤生长的效果。

Ba/F3-EpoR-JAK2V617F驱动恶性肿瘤小鼠模型
接着,我们探究了CLJ-44在Ba/F3-EpoR-JAK2V617F驱动恶性肿瘤小鼠模型中的机制和药效。Babl/c-nude小鼠(北京华阜康生物科技股份有限公司)接收后适应环境,当小鼠饮食活动均正常后,开始建模。常规培养Ba/F3-EpoR-JAK2V617F细胞(四川大学生物治疗国家重点实验室),当生长至80%融合度时,1000rpm离心3min收集细胞,PBS重悬细胞,细胞计数仪进行细胞计数,并计算细胞存活比例,活细胞比例超过90%方可用于实验,调整细胞浓度到1×10 7个/mL,细胞收集完成后,细胞悬液置于冰上预冷,每只老鼠接种量为1.0×10 6/只,批量诱导建模。阳性对照药物Ruxolitinib磷酸盐和Fedratinib购自四川蜀研生物科技有限公司。给药方式采用一天两次口服给药,空白对照组和模型组小鼠口服等体积生理盐水,结果如图3所示,4个剂量的CLJ-44抑制脾脏增长效果呈良好的剂量依存关系。在CLJ-447.5、15、30、45mg/Kg的剂量下,各组脾脏增长抑制分别为18.74%,35.67%,79.79%和101.08%,阳性对照药物Ruxolitinib磷酸盐和Fedratinib脾脏增长抑制分别为35.09%和40.23%。CLJ-44低剂量15mg/Kg的抑制脾脏增长效果与阳性对照药物Ruxolitinib磷酸盐和Fedratinib 30mg/Kg的效果相当。当CLJ-44以30mg/Kg的剂量治疗Ba/F3-EpoR-JAK2V617F驱动恶性肿瘤小鼠时,治疗效果远远优于同等剂量下的阳性对照药物Ruxolitinib磷酸盐和Fedratinib。在CLJ-4445mg/Kg的剂量下,Ba/F3-EpoR-JAK2V617F驱动恶性肿瘤小鼠脾脏恢复正常小鼠重量。
JAK2V617F诱导骨髓纤维化模型
JAK2突变型JAK2V617F基因载体MSCV-JAK2V617F-GFP(成都万道生物科技发展有限公司),BALB/c小鼠(江苏集萃药康生物科技有限公司)作为供体,取小鼠骨髓细胞,感染JAK2V617F病毒,然后将感染病毒的骨髓细胞通过尾静脉回输到X射线致死照射的BALB/c受体小鼠中,即可诱导出JAK2V617F阳性的骨髓纤维化小鼠模型。在建模45天后,通过流式分析外周血发现,GFP+肿瘤细胞群比例在10%以上,判定达到给药标准。给药方式采用一天两次口服给药,空白对照组和模型组小鼠口服等体积生理盐水,经过长达8周的治疗后,结果如图4所示,在JAK2V617F诱导骨髓纤维化小鼠模型中,CLJ-4430mg/Kg组抑制脾脏增长率为96.73%,Fedratinib 30mg/Kg组抑制脾脏增长率为29.46%,所以当CLJ-44以30mg/Kg的剂量治疗JAK2V617F诱导骨髓纤维化小鼠时,治疗效果远远优于同等剂量下的阳性对照药物Fedratinib。
虽然,上文中已经用一般性说明、具体实施例和实验,对本发明做了详尽的描述,但在本发明的基础上,可以对其进行一些修改或改进,这对于本领域技术人员而言是显而易见的。因此,在不偏离本发明精神的基础上所做的修改或改进,均属于本发明要求保护的范围。
