Description
技术领域
本发明涉及对激酶具有抑制活性的新的2,3,5-取代的噻吩化合物、包含所述化合物作为活性成分的抗癌剂以及用于制备所述化合物的方法。
背景技术
蛋白激酶是催化定位于蛋白质中的酪氨酸残基、丝氨酸残基和苏氨酸残基上的羟基的磷酸化的酶,在引起细胞生长、分化和增殖的生长因子信号的转导中起重要作用。
为了维持生物体的稳态,体内信号转导系统需要在打开和关闭之间平稳地保持平衡。然而,特定蛋白激酶的突变或过表达破坏正常细胞(通常处于体内信号转导继续的状态)中的信号转导系统,从而引起多种疾病,例如癌症、炎症、代谢疾病和脑疾病。引起异常细胞生长疾病的代表性蛋白激酶的实例包括Raf、KDR、Fms、Tie2、SAPK2a、Ret、Abl、Abl(T315I)、 ALK、极光激酶A、Bmx、CDK/周期蛋白E、Kit、Src、EGFR、EphA1、 FGFR3、FLT3、Fms、IGF-1R、IKKb、IR、Itk、JAK2、KDR、Met、mTOR、 PDGFRa、Plk1、Ret、Syk、Tie2、TrtB等。因此,通过开发对多种蛋白激酶中的特定激酶具有选择性抑制活性的化合物,从而进行了开发目标抗癌剂的研究。
同时,急性髓细胞性白血病(acute myeloid leukemia,AML)是致死性血液疾病之一,并且是血细胞连续增殖同时异常分化的疾病。Fms样酪氨酸受体激酶-3(Fms-Liketyrosine receptor kinase-3,FLT3)通常在造血干细胞和祖细胞中表达,并且是在造血中发挥重要作用的受体酪氨酸激酶。FLT3是患有急性髓细胞性白血病的患者中最经常突变的基因之一。在患有AML的患者的约25%的病例中,FLT3基因突变成FLT3-ITD,并且FLT3-ITD突变是使早期诊断困难的主要因素之一。除了FLT3-ITD突变之外,已经报道了活化环(activation loop)中的D835氨基酸的点突变 (D835Y、D835V和D835F)。这些突变在约10%的患有AML的患者中发现,并且通过使FLT3的失活状态不稳定来诱导FLT3的过度活跃。过度活跃的突变如FLT3-ITD和FLT3-D835点突变通过连续增加与血细胞分化和增殖有关的较低信号而引起AML。因此,诱导AML的FLT3突变已经成为AML靶向治疗剂的开发中的药物靶标。
作为迄今为止开发的采用FLT3作为靶标的新药候选材料,来他替尼、舒尼替尼、索拉非尼、quizartinib、tandutinib等已进入临床试验。已经报道所有的候选材料对FLT-ITD突变体表现出强的活性,然而quizartinib诱导FLT3-ITD+F691L、FLT3-ITD+D835Y、FLT3-ITD+F691L+D835Y(三重突变体)等的抗性突变体。因此,迫切需要开发对抗药性的FLT3点突变也具有抑制活性的新化合物作为急性髓细胞性白血病(AML)的靶向治疗剂。

实验例2:对Ba/F3细胞系的抑制活性的测量
将表达FLT3突变基因的Ba/F3细胞系在包含90%RPMI、10%FBS 和抗生素(Welgene)的培养液中培养。将100uL的Ba/F3细胞系置于经 TC处理的96孔板(SPL)的5,000个孔中的每个孔中,然后向其中分别注入1uL用二甲基亚砜稀释的测试化合物(从1mM浓度各自稀释3个点,总共10个浓度)。此后,将所得细胞系在细胞培养箱中孵育72小时。向其中添加50uL细胞滴度glo(Promega)溶液,将所得混合物在室温下储存10分钟,然后通过使用读数器(Envision,PerkinElmer)测量发光强度。发光强度显示为测试化合物的每种最终浓度的图,并且通过使用Prism 5.0(GraphPad)软件获得GI50值。
通过使用供应有小鼠IL-3(R&D Systems)的培养液来培养无FLT3 突变基因的亲本Ba/F3细胞系,使得在包含90%RPMI、10%FBS和抗生素(Welgene)的培养液中的最终浓度变为1ng/mL。通过与如上所述相同的方法来测量活性。
