Description
技术领域
本发明属于生物医药技术领域。更具体地,涉及一种硫脲化合物及其制备方法与应用。
背景技术
自噬是真核细胞中高度保守,经溶酶体途径降解生物大分子和细胞器的代谢过程。自噬作为细胞降解系统中的重要途径,主要降解细胞胞浆中长寿命蛋白、受损细胞器等,维持细胞的蛋白质稳态、能量代谢等,保持细胞的生理功能。自噬功能受抑制或过度激活是许多疾病发生发展的重要因素,如自噬功能受损是神经退行性疾病的重要特征。在亨廷顿病、帕金森等神经退行性疾病中,突变型亨廷顿蛋白mHTT、路易小体α-synuclein等毒性蛋白累积,引发神经细胞毒性,是造成疾病的重要成因。因此,促进神经毒性蛋白的自噬性清除是治疗亨廷顿病、帕金森病等神经退行性疾病的可行策略。如中国专利申请公开了一种醋酸棉酚在制备治疗神经退行性疾病药物中的应用,其通过醋酸棉酚激活自噬通路发挥作用,从而达到治疗神经退行性疾病的作用。但目前通过促进自噬清除神经毒性蛋白治疗神经退行性疾病化合物的研究较少,迫切需要提供多几种促进自噬清除神经毒性蛋白治疗神经退行性疾病化合物。

具体实施方式
以下结合说明书附图和具体实施例来进一步说明本发明,但实施例并不对本发明做任何形式的限定。除非特别说明,本发明采用的试剂、方法和设备为本技术领域常规试剂、方法和设备。
除非特别说明,以下实施例所用试剂和材料均为市购。
实施例1硫脲化合物J3的制备
反应方程式如下:
将5mmol苯甲酰基异硫氰酸酯与6mmol 5-氨基-3-甲基-2,4-噻酚二羧酸二乙酯加入到100ml的圆底烧瓶中,向圆底烧瓶中加入30mL无水乙腈,安装冷凝管,将反应体系置于油浴中搅拌回流反应,通过薄层色谱(TLC)指示反应完成后,将反应体系冷却至室温,待固体析出,抽滤、洗涤并收集滤饼,真空干燥滤饼可得产物硫脲化合物J3:5-苯甲酰基硫脲-3-甲基-2,4-噻酚二羧酸二乙酯。
结构表征:

对硫脲化合物J3进行核磁氢谱测试,结果如图2所示:硫脲化合物J3的分子氢谱波峰与目标产物一一对应,数量合理;
对硫脲化合物J3进行质谱测试,结果如图3所示:硫脲化合物J3的质谱图中相对分子质量与所合成的J3的相对分子质量一致。
实施例2 J3在细胞水平降解突变型亨廷顿蛋白的实施例
用20μM的J3处理突变亨廷蛋白顿模型细胞(CFP-103Q-HeLa,HeLa细胞在HTT第一个外显子插入含人源103个谷氨酰胺残基的polyQ结构并融合表达青色荧光蛋白的稳转细胞株)48h后,检测可溶性和不可溶性突变型亨廷顿蛋白表达水平或检测突变型亨廷顿蛋白聚集体数量。
对于蛋白水平检测,取培养板,吸去培养基,用预冷的PBS清洗细胞培养板2~3次,吸去PBS,加入适量含有蛋白酶抑制剂Cocktail的裂解液,用细胞刮轻轻将细胞刮下,收集细胞裂解液至预冷的1.5mL EP管中,冰上裂解30min后在4℃低温环境下以15000xg的速度,离心20min,将上清液转移至新的EP管中,得到可溶性突变型亨廷顿蛋白(Soluble mHTT);
将离心下来的细胞沉淀用预冷的裂解液洗3次,加入含4%十二烷基硫酸钠(SDS)的裂解液后以40%振幅超声破碎20次,每次1s,超声结束后,100℃煮沸30分钟,得到不可溶突变型亨廷顿蛋白(Insoluble mHTT)。对两部分蛋白分别采用BCA法测定蛋白浓度,加入5xLoading Buffer和PBS将蛋白上样量调整一致,置于95℃水浴锅中煮5min,得到蛋白样品。
使用SDS-PAGE进行电泳,经蛋白质免疫印迹(western blot),对可溶性突变型亨廷顿蛋白和不可溶性突变型亨廷顿蛋白进行化学发光成像(分别测试用20μM的J3处理CFP-103Q-HeLa处理0、12、24、48小时时的成像情况),对条带进行分析。
如图4所示,采用western blot检测J3不同给药时间梯度后Insoluble mHTT、Soluble mHTT、β-肌动蛋白(β-Actin)的表达水平,β-Actin作为内参蛋白,可见SolublemHTT、Insoluble mHTT随时间增长逐渐降低(左图)。统计结果显示,用J3处理24h以及48h后的Soluble mHTT(中间图)、Insoluble mHTT(右图)表达水平与0h相比均显著降低。
对于突变型亨廷顿蛋白聚集体数量进行检测,吸去细胞培养板中的培养基,加入PBS清洗三次,吸去PBS,加入4%多聚甲醛固定15min,吸去多聚甲醛,PBS轻柔洗三次,在激光共聚焦显微镜中以CFP通道观察用完全培养基(CM)以及20μM的J3给药48h后蛋白聚集体的数量变化和弥散的CFP荧光变化。
如图5所示,用20μM的J3给药48h后荧光显示减少(左图),从统计图中可以看出,与CM相比,突变型亨廷顿蛋白聚集体数量显著下降(右图),证明本申请硫脲化合物J3能显著降解突变型亨廷顿蛋白。
实施例3 J3在细胞水平诱导突变型亨廷顿蛋白通过自噬-溶酶体途径降解的实施例
氯喹(CQ)是一种常用的自噬后期阻断剂,能够抑制溶酶体酸化,阻断自噬底物降解,单用CQ时的LC3-II即为细胞本底自噬水平,用20μM的J3与40μM的CQ单用或联用处理野生型HeLa细胞6h后采用western blot进行检测后,用western blot检测微管相关蛋白1轻链3I(LC3-I)、微管相关蛋白1轻链3II(LC3-II)、甘油醛-3-磷酸脱氢酶(GAPDH,内参蛋白)的表达水平。
如图6所示,J3诱导的LC3-II在合用CQ后表达水平较单用CQ更高(左图),统计结果同样显示与单用CQ相比,J3诱导的LC3-II在合用CQ后出现进一步累积(右图),可见,J3能增加自噬流,是一种自噬诱导剂。
用20μM的J3与40μM氯喹(CQ)单用或联用处理CFP-103Q-HeLa细胞6h后用westernblot检测Insoluble mHTT、Soluble mHTT、β-肌动蛋白(β-Actin)的表达水平。
如图7所示,与完全培养基(CM)相比J3单用能够降低突变型亨廷顿蛋白表达,J3与CQ联用时Soluble mHTT、Insoluble mHTT表达水平均较J3单用更高(左图)。统计结果同样显示J3能够减少Soluble mHTT、Insoluble mHTT的表达量,而J3降解mHTT的效果能够被CQ逆转,与单用J3处理组相比,Soluble mHTT、Insoluble mHTT表达均有回升(右图),这表明J3可通过自噬-溶酶体途径清除mHTT。
正常野生型亨廷顿蛋白承担着神经保护功能,有重要的生理意义,用20μM的J3和1μM的雷帕霉素(Rap)处理野生型HeLa细胞48h后检测检测野生型亨廷顿蛋白(HTT)、GAPDH的表达水平。
如图8所示,Rap处理后,HTT的表达有一定的降低,但使用J3处理后,HTT的表达水平无明显变化(左图)。统计结果显示Rap对野生型亨廷顿蛋白具有一定的降解作用,J3处理细胞后野生型亨廷顿蛋白的变化无统计学意义(右图),说明J3对野生型亨廷顿蛋白无显著降解效果,结合实施例2中J3能够显著降解突变型亨廷顿蛋白,证明其降解作用对突变型亨廷顿蛋白有一定选择性。
实施例4 J3的安全性实施例
本次实验采用Q140模型小鼠,该类型小鼠的主要表型是活力下降,步态紊乱,运动功能受损。通过基因敲入的方法将亨廷顿病(Huntington’s Disease,HD)患者带有CAG重复扩增的HTT基因的exon 1替换小鼠基因组HTT的exon1,这类小鼠可利用内源性HTT启动子表达mHTT蛋白,在遗传学背景上接近HD病人。
实验中,将小鼠分为野生型(WT)和HdhQ140模型组(HdhQ140/Q140),其中HdhQ140模型组按照体重随机分为3组,溶媒组(注射纯玉米油)12只(HdhQ140:Vehicle);J3低剂量(30mg/kg)组10只;J3中剂量(60mg/kg)组10只;野生型组(WT:Vehicle,注射纯玉米油)12只。J3用玉米油溶解后充分混悬,配制成对应浓度的混悬液,按0.1mL/10g腹腔注射给药,每2天一次,连续给药12周,记录给药期间1~10周小鼠体重变化和用3%水合氯醛麻醉后,对心脏(Heart)、肝脏(Liver)、肾脏(Kidney)进行苏木精-伊红(HE)染色初步分析毒性。
如图9所示:J3低剂量组与中剂量组处理的雄性小鼠(Male Mouse,上图)、雌性小鼠(Female Mouse,下图)在给药过程体重(Weight)与野生型组和HdhQ140模型组相比均无明显减少。证明了硫脲化合物J3对小鼠无明显毒副作用。
如图10所示:在HE染色结果中,心脏、肝脏、肾脏细胞排列整齐,肾脏中肾小球球囊腔清晰可见,J3低剂量组(30mg/kg)对小鼠脏器无明显毒副作用,结合实例5中J3低剂量组就能够显著降低亨廷顿蛋白表达、改善生物标志物,说明J3低剂量组足以达到给药效果且无明显毒副作用。
实施例5 J3降低亨廷顿蛋白表达、改善生物标志物的实施例。
将小鼠分为野生型(WT)和HdhQ140模型组(HdhQ140/Q140),其中模型组小鼠按照体重随机分为3组,分别是溶媒组(注射纯玉米油)12只(HdhQ140:Vehicle或HdhQ140/Q140);J3低剂量(30mg/kg)组10只;J3中剂量(60mg/kg)组10只。野生型组(WT:Vehicle或WT,注射纯玉米油)12只小鼠。J3用玉米油溶解后充分混悬,配制成对应浓度的混悬液,按0.1mL/10g腹腔注射给药,每2天一次,连续给药12周,给药结束后恢复三天,进行旷场试验、平衡木试验,用3%水合氯醛麻醉后取小鼠脑组织并提取纹状体总蛋白,检测总亨廷顿蛋白(T-HTT)、中间多棘神经元标志物(DARPP-32),内参蛋白α微管蛋白(α-tubulin)。
如图11所示:与HdhQ140/Q140组相比,J3低剂量(30mg/kg)给药后,T-HTT表达减少,DARPP-32的表达有显著上调(左图),统计结果显示与WT组相比,HdhQ140/Q140组亨廷顿蛋白出现更大分子量的蛋白片段,DARPP-32明显下调,说明模型构建成功。与HdhQ140/Q140组相比,J3低剂量(30mg/kg)给药可清除亨廷顿蛋白,且对DARPP-32的表达有显著上调(右图)。证明了J3低剂量组能够显著降低亨廷顿蛋白表达、改善生物标志物。
如图12所示:与HdhQ140/Q140组相比,J3中剂量(60mg/kg)给药后,T-HTT表达减少,DARPP-32的表达有显著上调(左图),统计结果显示与HdhQ140/Q140相比,J3中剂量(60mg/kg)给药可清除亨廷顿蛋白,且对DARPP-32的表达有显著上调(右图)。证明了J3中剂量组能够显著降低亨廷顿蛋白表达、改善生物标志物。
如图13所示:免疫组化实验结果与western blot结果类似,可见与WT组相比,HdhQ140/Q140组小鼠纹状体亨廷顿蛋白高表达,细胞核周围亨廷顿蛋白高表达,DARPP-32表达下调。与HdhQ140/Q140组相比,低剂量、中剂量组别中J3可清除亨廷顿蛋白,对DARPP-32的表达同样有一定的上调。证明了与HdhQ140/Q140组相比,30mg/kg、60mg/kg J3均可体内水平降解亨廷顿蛋白,改善棘神经元标志物DARPP-32的表达水平。
如图14所示:左图旷场实验(Open field test)中,J3给药后,小鼠爬壁站立次数显著增加,自主活力上升(左图)。平衡木试验(Balance beam test)的中,J3给药后,小鼠四肢跌落次数显著减少(中图),小鼠的运动平衡、协调能力增强(右图)。证明了与HdhQ140/Q140组相比,30mg/kg、60mg/kg J3均可改善相关行为学表型。
上述实施例为本发明较佳的实施方式,但本发明的实施方式并不受上述实施例的限制,其他的任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化,均应为等效的置换方式,都包含在本发明的保护范围之内。
