  • Neurodegenerative disorders refer to diseases caused by the abnormal death of central neurons and the dysfunction of the nervous system. There is currently a lack of neurodegenerative diseases, and there is no fundamental treatment method that can slow down the progression of the disease so far. Many neurodegenerative diseases are caused by proteins of unknown activity. At present, methods that may be used to control protein levels, such as biological tools such as RNAi or CRIPSR, are difficult to deliver, especially to the nervous system.
  • a feasible treatment strategy is to control the level of proteins that affect the disease through low molecular weight compounds (compounds for short).
  • Proteolytic targeting chimera (PROTAC) technology to enhance the ubiquitination of disease proteins and target them to the proteasome degradation pathway is an emerging method, but only this method relies on certain E3 ligases, which may Does not exist in diseased cells.
  • the protein degradation ability of the proteasome is limited, and the degradation efficiency of certain large disease proteins or aggregates that cause neurodegenerative diseases is low.
  • autophagy is commonly found in eukaryotic cells. It has strong protein degradation ability but low selectivity.
  • PolyQ-related neurodegenerative diseases are a type of neurodegenerative diseases caused by variant proteins, which can be effectively treated by reducing the levels of variant proteins. Take Huntington’s disease (HD), the most common among them, as an example. This is a single-gene inherited disease. The mutation in the CAG repeat region of the exon1 exon of the HTT gene contained in the patient’s chromosome 4 results in a synthetic variant protein (mHTT). The glutamine repeat region (polyQ) is amplified. mHTT is susceptible to shearing, aggregation and toxicity, which eventually leads to specific neuron dysfunction and death. The current methods for controlling mHTT levels through low molecular weight compounds lack specificity, may cause side effects, and are non-allelective. They cannot distinguish between mHTT and wild-type HTT protein (wtHTT), which will lead to a decrease in wtHTT level, which has important biological functions.

Description

用于治疗神经退行性疾病的化合物 技术领域
本发明涉及生物医药领域,并且具体地涉及一种具有取代的双环结构的化合物,其药学上可接受的盐、立体异构体、溶剂化物、多晶型、互变异构体、同位素化合物、代谢产物或前药,在制备用于预防或治疗聚谷氨酰胺(polyQ)相关的疾病的药物中的用途。
背景技术
神经退行性疾病(Neurodegenerative Disorder)是指中枢神经元不正常死亡引起神经系统功能障碍而导致的疾病。目前缺乏针对神经退行性疾病,迄今为止没有可以减缓疾病发展进程的根本性治疗方法。许多神经退行性疾病是由活性未知的蛋白引起的。目前可能用于控制蛋白水平的方法例如RNAi或CRIPSR等生物工具,但其递送困难,尤其向神经系统的递送难以实现。
一种可行的治疗策略是通过低分子量化合物(简称化合物)来控制影响疾病的蛋白的水平。通过蛋白裂解靶向嵌合体(PROTAC)技术增强疾病蛋白的泛素化并将其靶向蛋白酶体降解途径是一种新兴方法,但仅这种方法依赖于某些E3连接酶,这些连接酶可能不存在于疾病细胞中。并且,蛋白酶体的蛋白降解能力有限,对导致神经退行性疾病的某些大型疾病蛋白或聚集体降解效率较低。自噬作为重要的蛋白降解途径,普遍存在于真核细胞中,蛋白降解能力强,但选择性较低。部分研究通过增强自噬作用来增加蛋白降解,但这样的方法缺乏特异性。
polyQ相关的神经退行性疾病是一类变异蛋白引起的神经退行性疾病,可以通过降低变异蛋白水平而得到有效治疗。以其中最常见的亨廷顿病(HD)为例,这是一种单基因遗传的疾病,患者的四号染色体所含基因HTT的exon1外显子的CAG重复区域变异导致合成的变异蛋白(mHTT)的谷氨酰胺重复区域(polyQ)扩增。mHTT易被剪切、聚集并产生毒性,最终导致特定神经元功能障碍和死亡。目前通过低分子量化合物控制mHTT水平的方法缺乏特异性,可能造成副作用,并且是非等位选择性的,无法区分mHTT与野生型HTT蛋白(wtHTT),会导致具有重要生物学功能的wtHTT水平降低。
同样,以脊髓小脑共济失调3型(SCA3;又称为Machado-Joseph disease,MJD)为例,这是全世界最常见的常染色体显性脊髓小脑共济失调和仅次于HD的常见polyQ相关疾病,由Ataxin-3基因(ATXN3;又称为MJD1基因)CAG重复数目增多导致编码蛋白ATXN3的C末端形成异常扩增的polyQ引起。一些研究通过siRNA、反义寡核苷酸等手段作用于ATXN3,减少变异ATXN3蛋白的表达,并证实了变异ATXN3蛋白的水平 降低能够带来治疗效果(Wang,Neuroscience,371,2018,138–154)。一些研究致力于通过低分子量化合物控制变异ATXN3蛋白的水平。通过化合物增强自噬作用的研究例如:Menzies et al.,Brain 2010,133:93–104;通过调节其他靶标来降低变异ATXN3蛋白的水平的研究例如:Costa MD,Brain,2016,139(11):2891-2908。但是这些研究都没有很好地解决特异性的问题。

发明人使用外源性表达polyQ-GFP融合蛋白(Q72-GFP或Q25-GFP)的HEK293T细胞,检测在细胞中能够对含有较长谷氨酰胺重复区域的蛋白的水平进行控制的化合物。方法如下:
(1)从头合成polyQ-GFP cDNA序列(表达Met-polyQ-GFP,其中polyQ为Q72或Q25)并亚克隆到pcDNA载体中。将其正向转染到HEK293T细胞(ATCC,CRL-3216)中,分别得到表达Q72-GFP的细胞和表达Q25-GFP的细胞。并且,用同样的方法获得表达Q53-GFP的细胞、表达Q46-GFP的细胞、表达Q38-GFP的细胞。
(2)分别纯化通过(1)表达的polyQ-GFP蛋白,以获取Q72-GFP、Q53-GFP、Q46-GFP、Q38-GFP和Q25-GFP(SEQ ID NO:1)。其中Q72-GFP、Q53-GFP、Q46-GFP、Q38-GFP与SEQ ID NO:1的氨基酸序列相比,区别在于谷氨酰胺重复区域的长度。
(3)使用步骤(1)中获得的表达Q72-GFP的细胞和表达Q25-GFP细胞。用100nM浓度的化合物1,或50nM浓度的化合物2处理细胞,2天后通过Incucyte检测荧光计数测量polyQ-GFP水平(图1)。观察到化合物1和化合物2能够有效降低HEK293T细胞中含有较长谷氨酰胺重复区域的蛋白(Q72-GFP)的水平,但不降低含有较短谷氨酰胺重复区域的蛋白(Q25-GFP)的水平。这一结果表明本发明化合物在细胞中能够选择性地降低polyQ异常扩增的蛋白的水平。

3.1化合物与全长HTT的亲和活性的OI-RD检测
使用接触式微阵列点印机(SmartArrayer 136,CapitalBio Corporation),按照现有技术(Zhu et al.,Sensors(Basel)2016,16(3),378;Fei et al.,J Biomed Opt 2010,15(1),016018)的方法制备化合物芯片。每个化合物各点印三份。用OI-RD测量化合物与全长mHTT(flHTT-Q73)和全长HTT-Q23(flHTT-Q23,SEQ ID NO:2)的亲和反应参数(图2)。化合物与fl-HTT-Q23没有亲和结合,与flHTT-Q73的亲和反应的结合速率常数、解离速率常数和平衡解离常数如表2所示。

3.2化合物与全长HTT的亲和活性的MST检测
用微量热泳动仪(MST,其中Monolith NT.115仪器来自NanoTemper Technologies)对化合物与全长HTT的亲和活性进行验证(图3)。反应缓冲液为20mM HEPES,pH 7.4,150mM NaCl,蛋白浓度500nM。本发明的化合物与fl-HTT-Q23没有亲和结合。化合物 1与flHTT-Q73的K d为0.13μM;化合物2与flHTT-Q73的K d为2.82μM。
综上,OI-RD检测和MST检测结果均表明本发明的化合物选择性地亲和结合flHTT-Q73。这一结论与化合物在HEK293T细胞中选择性地降低含有较长谷氨酰胺重复区域的蛋白水平的现象具有内在的一致性,说明化合物对上述蛋白水平的影响可能是通过选择性地与含有较长谷氨酰胺重复区域的蛋白结合而实现的。

(1)用化合物处理原代培养的Hdh Q140/Q7和Hdh Q7/Q7小鼠皮质神经元细胞,2天后通过蛋白印迹(2166抗体)检测mHTT、wtHTT水平(图4和图5)。化合物1和2使Q140基因敲入杂合小鼠(Hdh Q140/Q7)皮质神经元mHTT水平降低,而几乎不影响wtHTT水平。化合物1不降低Hdh Q7/Q7小鼠皮质神经元wtHTT水平。
(2)用抗polyQ抗体MW1和3B5H10检测mHTT,并且观察分子量较小的蛋白的条带,结果没有观察到mHTT的N-端碎片的增加(图6)。检测到的mHTT水平降低不是由于位点特异性剪切的增加。

用DAPI对神经元特异性微管蛋白标记物TUBB3染色。以细胞核计数对TUBB3信号覆盖面积进行归一化,并以野生型为对照,对数据进行归一化,分析神经元凋亡(图12)。
(2)胱天蛋白酶-3活性检测
在去除BDNF后,观察到HD神经元停滞,并出现了神经元收缩。
用NucView 488(Biotium,30029)检测活性胱天蛋白酶-3。去除BDNF后,使用Incucyte(Essen Bioscience,IncuCyte FLR)在培养箱内每3小时捕获图像,用Incucyte 2011A软件分析。共测试三批,结果一致(图13)。化合物1和2对于去除BDNF后HD神经元的停止进展和神经元收缩有明显的改善。

实验方法:每天进行一次脑室内注射,每次注射给药2μL含有浓度为25μM的化合物的人造脑脊液(ACSF:1mM葡萄糖,119mM NaCl,2.5mM KCl,1.3mM MgSO 4,2.5mM CaCl 2,26.2mM NaHCO 3,1mM NaH 2PO 4)。将含有等量DMSO的2μL ACSF用作对照。
注射10天后,提取小鼠脑皮质神经元蛋白,通过蛋白印迹(2166抗体)检测mHTT和wtHTT水平。每个样品重复检测3次,计算平均值(图17)。化合物2显著降低HdhQ140/Q7小鼠皮质mHTT水平,并相对于wtHTT表现出mHTT选择性。
8.2腹腔注射给药化合物2
实验方法:将化合物或对照用的DMSO用0.9%NaCl静脉内输注溶液稀释至0.05μg/μL,每天进行一次腹腔注射(0.5mg/kg),注射14天后,进行组织提取或行为学实验。
腹腔注射小鼠脑组织的体内化合物检测:小鼠腹腔注射给药DMSO或化合物之后2小时,解剖取脑,称重,提取脑组织内的化合物,用UPLC-MS(Acquity超高效液相色谱系统、Acquity UPLC BEH C18(1.7μm,2.1×50mm)柱和Xevo TQ-S质谱仪,Waters Corporation,Milford,MA,USA)进行LC-MS/MS分析。到达脑组织的化合物2水平为9.48ng/g。对照(DMSO)组未观测到化合物质谱信号。本发明的化合物能顺利透过BBB 递送至小鼠的脑,有利于通过口服给药化合物。
8.3腹腔注射化合物对HD小鼠皮质和纹状体mHTT和wtHTT水平的影响
(1)取Hdh Q140/Q7小鼠(5月龄),共13只,分为2组
按照8.2所述步骤给药化合物2。每天进行一次腹腔注射,注射14天后,提取蛋白,通过蛋白印迹检测HD小鼠皮质中的mHTT和wtHTT水平(图18)。
(2)取Hdh Q140/Q7小鼠(10月龄),共13只,每组6-7只。
按照上述方法给药并提取小鼠脑纹状体神经元蛋白,通过蛋白印迹检测mHTT和wtHTT水平(图19)。
(3)通过dot-blot实验(抗体:4C9,条形图示出重复检测两次的结果)和HTRF(抗体对:4C9/4C9)检测Hdh Q140/Q7小鼠皮质中的mHTT聚集物。每只小鼠平均重复取样两到三次(图20)。没有观察到mHTT聚集物的增加。化合物2给药组的mHTT水平降低不是由于mHTT溶解度变化。
综上,腹腔注射给药化合物2降低HdhQ140/Q7小鼠皮质和纹状体mHTT水平,并相对于wtHTT表现出mHTT选择性。因此化合物2具有开发为口服药物的前景。
8.4腹腔注射化合物2对HD小鼠行为缺陷的影响
实验动物:Hdh Q140/Q7小鼠,共32只,分为2组;(Hdh Q7/Q7)小鼠,共28只,分为2组
实验方法:按照8.2所述步骤给药化合物2。每天进行一次腹腔注射,注射14天后,进行行为学实验。
所有的行为学实验均在光照阶段进行。在开始实验之前,将所有小鼠在昏暗的红光下保持在行为测试室中一小时。
所有的行为学实验均在光照阶段进行。在开始实验之前,将所有小鼠在昏暗的红光下保持在行为测试室中一小时。
旋转棒试验:连续3天对小鼠进行预训练(旋转棒上以4rpm旋转2分钟)。然后在2分钟内以4至40rpm的加速速度测试小鼠5天。每次实验结果记录为在棒时间(旋转棒上的时间),直到从棒上跌落或直到任务结束。每次测试包括三次重复,试验间隔60分钟以减少压力和疲劳。分析每只小鼠三次试验的平均值(图21a)。
平衡梁试验:2厘米厚、总长度为100厘米的带刻度的棒,两侧悬挂于平台上。起点处有一道明亮的灯光,终点点处有一个装有食物的暗盒子。记录每只小鼠走过平衡梁的总时间(图21b)。本发明化合物能够改善HD模型小鼠的亨廷顿病相关行为缺陷,并且对野生型小鼠不产生影响。
