本申请要求于2016年10月20日向中华人民共和国国家知识产权局提交的第201610915634.9号中国发明专利申请的权益,在此将其全部内容以援引的方式整体并入本文中。
技术领域
本发明公开了一种咪唑类化合物晶型、盐型及其制备方法,还包括所述晶型和盐型在制备治疗脑血管疾病药物中的应用。
背景技术
蛋白酪氨酸激酶是一类将磷酸基团从ATP催化转移到位于蛋白质底物的酪氨酸残基的酶,其在正常细胞生长中起作用。许多生长因子受体蛋白通过酪氨酸激酶起作用,并且通过该过程影响信号,进而调节细胞生长。例如,FGFR(Fibroblast growth factor receptor,成纤维细胞生长因子受体)、VEGFR(Vascular endothelial growth factor receptor,血管内皮细胞生长因子受体)和PDGFR(Platelet-derived growth factor receptor,血小板衍生生长因子受体)。然而,在某些条件下,这些受体或者突变或者过量表达,变得异常,引起细胞繁殖不受控制,导致肿瘤生长,最终引发熟知的疾病——癌。生长因子受体蛋白酪氨酸激酶抑制剂通过抑制上述磷酸化过程,起到治疗癌和其他特征为非控制的或异常细胞生长的疾病。
不受控制的血管生成是癌症的标志。在1971年Dr.Judah Folkman提出,肿瘤生长取决于血管生成,(参见Folkman,New England Journal of Medicine,285:1182-86(1971)。根据Dr.Judah Folkman在不生长另外的血管以滋养肿瘤的情况下,肿瘤仅能生长到一定的尺寸。在其最简单的表述中指出,一旦发生了肿瘤“成活”,肿瘤细胞群的每次增加必须由在肿瘤上会聚的新毛细管的增加来进行。目前理解的肿瘤的“成活”是指肿瘤生长的血管前相,其中占几个立方毫米体积并且不超过几百万个细胞的肿瘤细胞群可以存活于现存的宿主微脉管上。
已经表明,可以通过抑制血管生成而不是抑制肿瘤细胞本身的增殖来治疗肿瘤。血管生成已经与大量不同类型的癌症相关,所述的癌症包括实体瘤和血液运载的肿瘤。与血管生成相关的实体瘤包括但不限于:横纹肌肉瘤,视网膜母细胞瘤,尤因肉瘤,成神经细胞瘤和骨肉瘤。血管生成与乳腺癌、前列腺癌、肺癌和结肠癌相关。血管生成还与血液运载的肿瘤相关,所述的血液运载的肿瘤如白血病,淋巴瘤,多发性骨髓瘤以及各种急性或慢性骨髓肿瘤疾病中的任何一种,其中发生白血细胞不受限制的增殖,通常伴随有贫血、削弱的血液凝固以及淋巴结、肝和脾的增大。还认为,血管生成在骨髓异 常中起一定的作用,所述的异常引起白血病、淋巴瘤和多发性骨髓瘤。
血管生成在癌症的转移中起主要作用,如果能够抑制或消除血管源活性,那么尽管肿瘤存在也将不生长。在疾病状态下,防止血管生成可以减少由新微血管系统的侵入而导致的损伤。针对血管源性过程的控制的疗法可能导致这些疾病的去除或减轻。
其中,FGFR(Fibroblast growth factor receptor,成纤维细胞生长因子受体)、VEGFR(Vascular endothelial growth factor receptor,血管内皮细胞生长因子受体)和PDGFR(Platelet-derived growth factor receptor,血小板衍生生长因子受体)抑制剂抑制血管生成研究越来越成熟。

实验例7:大鼠体外全血凝血过程中TXB2水平的释放的实验
实验原理:
体外凝血过程中,血栓素A2(TXA2)通路被激活,大量TXA2生成并迅速代谢转化为稳定形态即血栓素B2(TXB2)。
该通路的关键酶为血栓素合成酶,在体外凝血过程加入该酶的特异抑制剂(待测化合物),能够抑制TXA2的生成,从而减少TXB2的含量。
以抑制TXB2生成的IC50反映待测化合物的活性。
实验动物:
雄性Sprague-Dawley(SD)大鼠,购买自上海斯莱克实验动物中心
实验试剂:
0.9%生理盐水溶液,100M氢氧化钠溶液(溶媒),100uM血栓素合成酶抑制剂溶液,异氟烷
实验步骤和方法:
1、将生理盐水溶解的化合物溶液梯度稀释至所需浓度,于离心管中加入167uL化合物溶液。
2、雄性SD大鼠异氟烷麻醉,心脏取血,迅速加入离心管中至0.5mL,摇匀,放入37℃恒温水浴中孵育30分钟至血液全凝。
3、取出离心管,6000g,4℃离心5分钟,取血清。
4、使用LC-MS/MS-AG(API 4000)检测TXB2的含量。
数据分析:
以溶媒组为对照,根据以下公式,将每个样品的TXB2含量归一化为对照组%(Control%):Control%=(测试管TXB2含量-阴性管TXB2含量)/对照管TXB2含量×100
注:测试管:不同浓度化合物
阴性管:高浓度(100uM)血栓素合酶抑制剂
对照管:溶媒
使用GraphPad Prism,以化合物浓度为横坐标,Control%为纵坐标,将数据进行拟合,并计算IC50值。
实验结果见表10:
