Definitions

  • the present invention belongs to the technical field of pharmaceutical chemistry, and specifically relates to a compound containing spirocyclic and cyclocyclic structures which can be used to treat nervous system diseases and tumors (including brain gliomas) and a preparation method thereof.
  • Microtubules are important components of the cytoskeleton and are responsible for important physiological functions such as cell proliferation, maintaining cell morphology and intracellular material transport.
  • central nervous system its main functional cell neurons are a specific type of cell that no longer undergo mitosis and have a polarized cell morphology.
  • the axons that transmit nerve signals outward rely on the rapid transport tracks formed by cytoskeletal proteins such as microtubules to achieve rapid transmission of intracellular substances between the cell body and nerve endings. Under pathological conditions, the composition and function of microtubules change, and they participate in the pathological process of many important diseases.
  • Alzheimer's disease there are two typical pathological manifestations, namely the aggregation of ⁇ -amyloid protein (A ⁇ ) and Tau protein.
  • a ⁇ ⁇ -amyloid protein
  • Tau Tau protein
  • Tubulin stabilizers can promote the binding of Tau protein to tubulin, improve the transport and function of vesicles involved in the protein quality control system in cells, and reduce the formation of neurofibrillary tangle deposition by tau. Therefore, they can be used to treat Alzheimer's disease and other neurodegenerative diseases, such as Huntington's disease, Alzheimer's disease, Parkinson's disease, frontotemporal dementia, multiple sclerosis and traumatic nerve injury.
  • glioma malignant tumor in the central nervous system that is highly malignant and has a poor therapeutic effect
  • This type of disease generally occurs in proliferating glial cells in the brain.
  • disordered cell proliferation causes diseased glial cells to develop into malignant cancer cells. Therefore, microtubule stabilizers that can pass through the blood-brain barrier, specifically affect the malignant proliferation of glial cells, and are relatively harmless to neuronal cells also have strong application prospects for this type of central nervous system diseases.

Description

一种作为治疗神经系统疾病和肿瘤的多环化合物 技术领域
本发明属于药物化学技术领域,具体涉及一种可用于治疗神经系统疾病和肿瘤(包括脑胶质瘤)的含有螺环和并环结构的化合物及其制备方法。
背景技术
微管是细胞骨架的重要组成成分,担负着细胞增殖,维持细胞形态和细胞内物质运输等重要生理功能。在中枢神经系统,其主要功能细胞神经元是一类特异的细胞类型,不再发生丝分裂,而且具有极化的细胞形态。其向外传递神经信号的轴突依赖微管等细胞骨架蛋白形成的快速运输轨道实现细胞内物质在胞体和神经末梢之间的快速传播。在病理状态下,微管组成及功能发生变化,参与很多重要疾病的病理发生过程。例如在阿尔茨海默氏病中(AD)有两个典型的病理表征,即β-淀粉样蛋白(Aβ)和Tau蛋白的聚集。Tau过度磷酸化后失去了其与微管蛋白的结合功能并形成神经纤维缠结沉积下来,使得微管介导的轴突物质传递到影响,导致远端的轴突退行性病变。微管蛋白稳定剂可以促进Tau蛋白与微管蛋白的结合,并改善细胞内参与蛋白质质量控制系统的囊泡物质运输及功能,降低tau形成神经纤维缠结沉积,因此可以用于治疗阿尔茨海默氏症和其它神经退行性疾病,比如亨廷顿氏病、阿尔兹海默氏病、帕金森氏病、额颞叶痴呆症、多发性硬化症和创伤性神经损伤。
另一方面,中枢神经系统还有一类恶性程度很高,治疗效果很差的恶性肿瘤,如脑胶质瘤。这类疾病一般发生在脑中可增殖的胶质细胞中,和大多数肿瘤细胞一样,无序的细胞增殖造成病变胶质细胞发展成恶性癌细胞。因此,可通过血脑屏障的,特异影响胶质细胞恶性增殖,而同时对神经元细胞相对无害的微管稳定剂对于这类中枢系统疾病也有很强的应用前景。

测试方法:
在实验前一天,将100,000个细胞以200,000个/ml的密度接种在24孔板中。
实验当天,向孔中加入含有实验浓度的待测化合物或含等体积DMSO的20ulPBS磷酸盐缓冲液。在37℃下孵育1小时后,再向每孔加入终浓度1μM的秋水仙素,继续在37℃下孵育3小时后,将板置于冰上。除去每个孔中的培养基,并用预冷的PBS漂洗每孔细胞,然后吸去PBS迅速加入0.1ml预冷的RIPA细胞裂解液(含0.5%脱氧胆酸钠,0.1%SDS,1%NP-40,5mM EDTA,pH8.0)。细胞裂解液在使用前添加商业蛋白酶抑制剂混合物(1:500)和1μM脱乙酰酶抑制剂曲古抑菌A(Trichostatin A,生工生物工程股份有限公司)。将细胞裂解物加入1.5ml离心管中,超声,13,000rpm离心10分钟,随后取上清,用BCA法测定蛋白浓度。
根据已有文献(Black,1989.Kurt,2011.),使用乙酰化微管蛋白作为微管聚合性的指标检测化合物的稳定微管的效能。通过SDS-PAGE(7.5%凝胶)分析HEK293T细胞裂解物,使用乙酰化微管蛋白抗体(1:20000,Sigma-Aldrich,T7451)和α微管蛋白抗体(1:2000,Proteintech,11224-1-AP)进行免疫印迹,然后孵育荧光分子偶联的IgG(1:40000,Licor), 使用Odyssey-Dlx成像系统显影。ImageJ进行灰度分析。
