Abstract
本发明提供了一类α,β‑不饱和酰胺类化合物及其制备方法、药物组合物和用途,具体地,本发明提供了一种如下式I所示的化合物,其中,各基团的定义如说明书中所述。所述的化合物可以作为改善脑血流的化合物,用于制备治疗阿尔茨海默病、血管性痴呆等神经退行性疾病以及脑卒中的药物组合物。
Description
技术领域
本发明涉及药物化学和医药领域,具体涉及一类α,β-不饱和酰胺类化合物、其制备方法、含此类化合物的药物组合物,用于治疗阿尔茨海默病、血管性痴呆等神经退行性疾病以及脑卒中的药物的用途。
背景技术
阿尔茨海默氏病(Alzheimer’s disease,AD)是一种退行性大脑疾病,约占老年人痴呆症中的2/3,主要症状为记忆进行性丧失、β-淀粉样蛋白沉积(β-Amyloid,Aβ)和神经纤维缠结(Neurofibrillary tangles,NFT)等。AD的病理机制十分复杂,现有上市药物仅能短暂减缓或控制AD症状,靶向疾病机理的治疗尚未发现有效的途径。衰老是AD的最主要风险因素,95%以上的AD患者都是晚发型的,发病年龄在65岁以上。只有不到5%的AD是早发型的,发病原因主要为遗传因素。心脑血管疾病也是AD的主要风险因素,血管改变可能贡献于AD的病理发生,而不仅仅是已知的血管病变导致的血管性痴呆。毛细血管作为大脑中最丰富和最小的血管单位,其诱导的脑血流量(Cerebral blood flow,CBF)或血脑屏障(Bloodbrain barrier,BBB)的损伤与AD的记忆衰退有关。
越来越多的研究发现在AD的早期以及正常衰老-轻度认知障碍(Mild cognitiveimpairment,MCI)中,存在脑血流量降低、脑血管反应性损伤和血液动力学反应受损。早期研究发现,大脑中动脉经颅多普勒测量显示,具有较高脑血流量速度的个体患痴呆症或海马和杏仁核萎缩的可能性较小。MCI或AD早期的病人动脉自旋标记(Arterialspinlabeling)MRI显示在后齿状回和前突中脑血流量降低。在患AD高风险的老年人中脑血流量降低或脑血流量失调发生于认知能力下降,脑萎缩和β-淀粉样蛋白积聚之前。APOE是AD主要的遗传风险因子,同时是血管病变的易感基因。在动物模型中在以人APOE4基因125-127靶向替代鼠载脂蛋白E4(APOE)的转基因小鼠中,也发现脑血流量降低和血管功能障碍,而且还发现表达APOE4的小鼠的血管表型先于神经元和突触功能障碍。灌注不足会诱发或加剧阿尔茨海默氏病样的神经元功能障碍和神经病理学改变。慢性血流量减少50%将导致显著的认知变化,人脑血流持续的减少超过20%就会导致注意力丧失,而大鼠脑血流超过30%就会损害空间记忆。脑血流量减少会降低Na+/K+泵的活性以及依赖于它的所有过程(包括维持静息电位和glutamate摄取),它还会导致腺苷的产生,而腺苷会抑制谷氨酸的释放,进而影响神经元的功能。大鼠的双侧颈动脉阻塞会导致记忆障碍,神经元功能障碍,突触变化和β-淀粉样蛋白,从而导致神经毒性的β-淀粉样蛋白低聚物的积累。脑缺血、缺氧和Aβ沉积是相互影响的。灌注不足可触发Aβ加速沉积。Aβ反之会损伤脑血管功能,增加动脉血管收缩和降低脑血流量。在啮齿类动物,局部缺血导致神经元中高磷酸化Tau的积累和形成类似于人类神经退行性疾病和阿尔茨海默氏病中的纤维丝。灌注不足影响大脑的结构和功能变化,并提供了有希望的可能的生物标志物,可以潜在地识别诊断处于临床前状态的阿尔茨海默氏病。
毛细血管是大脑中最小的血管,从小动脉分支出来,形成了丰富的微血管网络,每克大脑的毛细血管最大表面积约为120cm2。毛细血管网络主要由内皮细胞,基底膜,周皮细胞,星形胶质细胞组成。在动物模型中已观察到毛细血管紊乱是痴呆症相关的神经退行性变化的先兆。AD的毛细血管收缩导致神经组织缺氧,这也可能是AD葡萄糖代谢下降的原因。而且缺血和缺氧已被证明可上调负责生成Aβ的酶β分泌酶(BACE1)。毛细血管血流主要通过周皮细胞调控,大量研究发现周皮细胞损伤与AD密切相关,在一些AD患者的大脑解剖样本中,周细胞的水平甚至会下降50%之多。周皮细胞缺陷转基因小鼠中,血流量降低,微血管减少,Aβ表达增加,血脑屏障通透性增加。许多神经病理学研究已经描述了在AD中脑毛细血管的形态改变以及类似于缺血性梗塞的脑室周围白质的病变。在晚期阿尔茨海默患者尸检研究显示脑内有大量毛细血管内皮细胞脱落,血管壁坍塌,密度减少。毛细血管由于其精细特殊的结构使其对损伤的易感性增加,毛细血管变性比血管淀粉样病变更频繁和普遍,潜在地表明AD脑微脉管系统的长期退化过程可能部分独立于淀粉样蛋白毒性。越来越多的研究表明血管因素是AD的主要危险因素,神经血管单元的损伤与AD相关。因此,寻找干预毛细血管提高脑血流可能对AD的预防及治疗有重要意义。
本发明提供一类靶向毛细血管提高脑血流,进而改善AD症状的目标化合物,用于临床阿尔茨海默病、血管性痴呆等神经退行性疾病以及脑卒中的治疗。

药理活性试验实施例
实施例1.本发明化合物对血流改善的活性测定
我们采用激光散斑测试血流量模型对化合物进行小鼠脑部血流改善的活性测试。其原理是通过激光散斑技术测量流动血液的光强变化,反映实时脑血流量;通过比较小鼠给药前后血流量变化程度可以检测化合物改善血流效果。
实验过程如图1中所示,将实验小鼠气麻30s后固定到架上,等待两分钟光强数据基线稳定,开始记录十分钟小鼠未给药时脑血流量光强度数据。随后通过腹腔注射测试化合物,并记录给药后六十分钟内小鼠脑血流量光强度数据。比较给药前后光强度变化可以获知小鼠脑血流量变化程度。
通过上述激光散斑模型,我们对实施例化合物进行了初步的小鼠脑部血流改善活性的测试,在本试验中采用阿魏酸(FA)作为阳性对照。化合物的血流改善效果见附图2,多个化合物在此模型中表现出对脑血流的明显改善作用,在5mg/kg剂量下,化合物9可使小鼠脑血流量提升约10%,化合物16可提升约20%。在20mg/kg剂量下,化合物30和59可使小鼠脑血流量提升约10%,化合物5、6、26、28、29、35、43和58均可使小鼠脑血流量提升约20%,化合物16、57和86可使小鼠脑血流量提升约30%,化合物27、84和104可提升约40%,化合物83可使小鼠脑血流量提升50%~60%。总体而言,本专利化合物具有良好的发展前景。
实施例3、本发明化合物体内药动学参数的测定
雄性ICR(CD-1)小鼠分为2组,每组3只,各组分别灌胃20mg/kg受试物或静脉注射5mg/kg受试物,分别在给药前、给药后0.25h、0.5h、1h、2h、4h、8h及24h取血,立即离心取血浆,以液相色谱-串联质谱法测定血浆中的药物浓度。
小鼠体内的药动学参数如下表所示。在小鼠体内,化合物27和83的口服生物利用度分别为14.7%和17.4%,具有良好的药代性质。
表2.化合物27和83在小鼠体内的药动学参数
另外,通过测定该化合物在脑组织的药物,发现该化合物具有良好的血脑屏障通透性,如表3所示,化合物27经小鼠口服后具有良好的脑组织药物分布,B/P约为0.7。
表3.脑组织的药物浓度测定
在本发明提及的所有文献都在本申请中引用作为参考,就如同每一篇文献被单独引用作为参考那样。此外应理解,在阅读了本发明的上述讲授内容之后,本领域技术人员可以对本发明作各种改动或修改,这些等价形式同样落于本申请所附权利要求书所限定的范围。
