Description
技术领域
本发明涉及一种靶向多巴胺D3受体的诊疗药物及其应用,属于化学技术领域。
背景技术
中枢神经系统的多巴胺受体是一类G蛋白偶联受体。研究表明,多种神经系统疾病与多巴胺受体相关,包括帕金森病、精神分裂症、药物成瘾等等(Zhan J,etal.Neuropharmacology 2018,141:11-20;Le Foll B,et al.Prog Brain Res 2014,211:255-275)。根据序列同源性、药理活性特点和蛋白结构,多巴胺受体分为D1、D2、D3、D4、D5五种亚型(Yang P,et al.Ageing Res Rev 2020,57:100994)。其中,多巴胺D3受体(D3R)在脑内纹状体、额叶、伏隔核、喀叶哈氏岛(islands of Calleja)、小脑等区域有相对高的表达(Barnes SA,et al.Psychopharmacology(Berl)2018,235:1403-1414)。研究表明,D3R的分布与功能变化与帕金森病、药物成瘾、不安腿综合征和精神分裂症等多种神经系统疾病相关(Nebel N,et al.Bioorg Med Chem Lett 2014,24:5399-5403)。
正电子发射计算机断层(PET)成像技术是分子影像领域的一种非侵入性、高灵敏性的体内成像技术,能够为疾病提供高度灵敏的、早期的影像诊断技术,还能监测疾病进程或治疗进展。PET成像技术应用于D3R的分子影像,能够分析脑内D3R的分布与功能变化情况,为D3R相关疾病诊断、治疗和疗效监测提供一种直观的影像学手段。而合适的靶向D3R的正电子类放射性药物是PET成像技术应用于D3R分子影像的必要条件。
目前,文献报道了一些[11C]标记的靶向D3R的正电子放射性药物,例如仅对D3R具有亲和性的[11C]-(+)-PHNO(Bini J,et al.J Nucl Med 2020,61:570-576)和[11C]RGH1756(Liow JS,et al.Molecules 2018,23),以及,对D2R和D3R都有亲和性的[11C]raclopride(Eisenstein SA,et al.Synapse 2013,67:748-756)等。其中,[11C]-(+)-PHNO药物性质良好,具有一定的应用潜力(Kiss B,et al.Biomolecules 2021,11:1-39)。但是,由于11C的半衰期过短(t1/2=20min),11C标记的放射性药物在临床应用上受到一定的限制。
氟[18F]是PET领域最常用的放射性核素,因具有合适的半衰期(t1/2=110min)、合适的正电子能量(Emax=0.634MeV),氟[18F]标记的靶向D3R的正电子放射性药物在D3R相关疾病诊断、治疗和疗效监测的临床应用上极具前景。目前,已报道的18F标记的靶向D3R的正电子放射性药物主要包括仅对D3R具有亲和性的[18F]FTP(Liow JS,et al.Molecules2018,23)和[18F]LS-3-134(Nebel N,et al.Bioorg Med Chem Lett 2014,24:5399-5403),以及,对D2R和D3R都有亲和性的[18F]fallypride(Nebel N,et al.J Labelled CompRadiopharm 2016,59:48-53)等。在这些药物分子结构中,18F标记在脂肪链的末端,这一策略虽然可以为药物的18F标记提供技术上的便利,但是不足之处在于体内稳定性不理想。研究表明,这一类18F标记D3R药物在体内容易在生物酶的作用下快速代谢而脱去18F,从而造成骨骼的高摄取,影响PET图像质量。并且,由于这类药物体内稳定性不佳,其药学性质不利于进行疾病与治疗效果评估(Savolainen H,et al.Mol Pharm 2015,12:2265-2275)。
因此,亟需研制体内稳定性好的18F标记的靶向D3R的正电子放射性药物以满足临床上对D3R相关疾病诊断、治疗和疗效监测的需求。

实验例1:靶向多巴胺D3受体的药物的放射性纯度分析与结构验证
本实验例提供了实施例2制得的药物[18F]5b的放射性纯度分析与结构验证,具体过程如下:
采用配有放射性和紫外检测器的分析型HPLC系统(Waters HPLC)对药物[18F]5b进行放射性化学纯度(RCP)检测。检测过程为:取1mCi的药物[18F]5b,用流动相稀释至放射性浓度~0.1mCi/mL,用HPLC进样针抽取20μL注入HPLC进行分析,HPLC分析所用的色谱柱为C18柱(4.6×150mm,5μm),洗脱所用流动相包括A相(含体积分数为0.1%TFA的甲醇)和B相(含体积分数为0.1%TFA的水),梯度洗脱条件为:0~6min,35%~55%B,6~12min,55%~68%B,12~15min,68%~35%B,流速1.0mL/min;根据分析所得图谱的色谱峰面积比,从而计算出所得放射性产物的化学纯度。检测结果为:药物[18F]5b的放射化学纯度为99%。
以对化合物5b作为对照,采用配有放射性和紫外检测器的分析型HPLC系统(Waters HPLC)对药物[18F]5b进行结构验证。验证过程为:将化合物5b和药物[18F]5b同时注入HPLC进行纯化,并且,分别用紫外(254nm)和放射性监测器对化合物5b和纯化后的药物[18F]5b洗脱液进行在线检测,HPLC纯化所用色谱柱为:Gemini C18反相色谱柱(4.6×150mm,5μm),洗脱所用流动相包括A相(含体积分数为0.1%TFA的甲醇)和B相(含体积分数为0.1%TFA的水),梯度洗脱条件为:0~6min,35%~55%B,6~12min,55%~68%B,12~15min,68%~35%B,流速1.0mL/min。验证结果见图4~5。
如图4~5所示,药物[18F]5b的保留时间在10.3min左右,该结果与化合物5b的色谱峰相对应,表明二者化学结构相同。
实验例2:靶向多巴胺D3受体的药物的体外稳定性实验
本实验例提供了实施例2制得的药物[18F]5b的体外稳定性实验,具体过程如下:
将药物[18F]5b分别用pH 7.4、0.1M的PBS缓冲液和胎牛血清(FBS)稀释至放射性浓度~1mCi/mL,得到稀释液1~2;将稀释液1~2在37℃下孵育1、2、4或6h,每个时间点准确取样20μL,并使用配有放射性和紫外检测器的分析型HPLC系统进行放射性化学纯度(RCP)检测。检测过程参见实验例1。
检测结果为:药物[18F]5b在PBS缓冲液和胎牛血清中孵育6h内RCP>98%,表明药物[18F]5b具有良好的体外稳定性。
实验例3:靶向多巴胺D3受体的药物的细胞摄取与阻断实验
本实验例提供了实施例2制得的药物[18F]5b的细胞摄取与阻断实验,具体过程如下:
将对数期生长的SH-SY5Y细胞(购自上海细胞库)以~2×105个/孔的添加量接种于添加有1000μL/孔不完全培养基(购自上海细胞库)的12孔板中,置于37℃,5%CO2的培养箱中培养24h使其充分贴壁。培养结束后,将30个孔分为正常对照组与阻断实验组,每组15个孔,每组每个时间点3个复孔;其中,正常对照组处理方法为:实验前弃去孔内培养基,在各孔中换上新鲜的不完全培养基继续孵育30min后,每孔各加入0.5μCi的药物[18F]5b进行共孵育15、30、60、90或120min;阻断实验组处理方法为:实验前弃去孔内培养基,在各孔中换上新鲜的不完全培养基继续孵育30min后,每孔各加入0.5μCi的药物[18F]5b和50μM D3受体阻断剂BP897进行共孵育15、30、60、90或120min。孵育结束后,再弃去孔内培养基,用冰冷的(0℃)pH 7.4、0.1M的PBS缓冲液洗涤12孔板两次,将洗涤液和弃去的培养基合并,得到合并液,并向孔内加入1.0mL 1M的NaOH溶液裂解细胞,得到裂解液。裂解结束后,将孔内裂解液转移至计数管中,再用0.5mL 1M的NaOH溶液清洗12孔板两次,将洗涤液和合并液合并,得到上清液。于放射性检测管中用γ计数仪分别测定正常对照组与阻断实验组在各个时间点的上清液和裂解液的放射性活度,计算上清液和裂解液放射性计数所占的百分比,计算结果见图6。
如图6所示,对于正常对照组,在0~15min,药物[18F]5b在SH-SY5Y细胞中快速摄取并达到最大摄取;SH-SY5Y细胞对药物[18F]5b在15、30、60、90和120min的摄取率分别为5.48±0.69%,7.04±0.56%,7.29±0.41%,8.49±0.08,8.45±0.5%;随着摄取时间的延长,细胞摄取逐渐增大,而90min后,细胞摄取逐渐平缓。而对于阻断实验组,在D3受体阻断剂BP897的作用下,SH-SY5Y细胞对药物[18F]5b在15、30、60、90和120min的摄取率分别降为3.4±0.07%,5.08±0.18%,4.56±0.19%,5.66±0.27%,5.65±0.08%;120min时,阻断实验组SH-SY5Y细胞对药物[18F]5b的阻断率达51%。上述结果表明,药物[18F]5b在细胞水平对多巴胺D3受体具有特异性结合。
实验例4:靶向多巴胺D3受体的药物的脂水分配系数实验
本实验例提供了实施例2制得的药物[18F]5b的脂水分配系数实验,具体过程如下:
将药物[18F]5b(~30MBq)加入含有3.0mL正辛醇和3.0mL pH 7.4、0.1M的PBS缓冲液的试管中后,先涡流震荡5min,然后在3000r/min下离心5min,使PBS相与正辛醇相分离。分别取1.0mL正辛醇层和1.0mL PBS层置于放射性检测管中,并用γ计数仪测定放射性活度。随后,另取1.0mL正辛醇相,重新分配到含有2.0mL正辛醇和3.0mL pH 7.4、0.1M的PBS缓冲液的试管中,继续上述实验5次,每组样品的LogP按公式LogP=Log(CPMn-辛醇/CPMPBS)计算,然后计算log P平均值。
测得药物[18F]5b的log P平均值为2.24(1.81-2.49),表明药物[18F]5b有可能穿过血脑屏障而进脑,从而对脑内多巴胺D3受体进行示踪成像。
实验例5:靶向多巴胺D3受体的药物的PET(microPET)成像实验
本实验例提供了实施例2制得的药物[18F]5b的PET(microPET)成像实验,具体过程如下:
将SD大鼠(购自江苏常州卡文斯实验动物有限公司,体重180克,年龄6周)分为正常对照组和阻断实验组;其中,正常对照组处理方法为:将正常的大鼠(n=5)用3%(v/v)的异氟烷吸入麻醉后,固定在microPET扫描床上,通过尾静脉注射270μCi(10MBq)的药物[18F]5b,从注射开始时刻起,扫描60min,整个扫描过程维持2.5%(v/v)异氟烷麻醉,在整个动态扫描期间,观察大鼠的呼吸状态;阻断实验组处理方法为:将大鼠(n=5)用3%(v/v)的异氟烷吸入麻醉后,固定在microPET扫描床上,按大鼠体重从尾静脉注射3mg/kg的D3受体阻断剂BP897,15min后,再通过尾静脉注射270μCi(10MBq)的药物[18F]5b,从注射开始时刻起,扫描60min,整个扫描过程维持2.5%(v/v)异氟烷麻醉,在整个动态扫描期间,观察大鼠的呼吸状态。两组动物扫描结束后,将获得的microPET数据进行图像重建,获得不同时间段内的重建图像,并采用感兴趣区(ROI)技术,生成时间-放射性活度曲线(TAC)。正常对照组与阻断实验组的microPET图像(0-60min)如图7所示。经ROI技术分析处理后TAC曲线如图8~9所示。
由图7可知,对于正常对照组,药物[18F]5b在大鼠脑内多巴胺D3受体分布相对密集的纹状体(ST)区域和小脑(CB)区域有中等放射性摄取,而经D3R阻断剂BP897预处理后的阻断实验组大鼠,其ST区域和CB区域的放射性摄取明显降低。该结果表明,药物[18F]5b在活体动物内对多巴胺D3受体具有特异性结合。不仅如此,从图7可以看出,药物[18F]5b在颅骨内的放射性摄取低,颅骨几乎不显影,表明药物[18F]5b在体内脱氟[18F]作用可以忽略不计,具有良好的体内稳定性。
由图8~9可知,对于正常对照组,药物[18F]5b在大鼠脑内纹状体区域的放射性摄取在注射后5min内达到高摄取量(SUV=1.61±0.16),然后逐渐下降,而用D3受体阻断剂BP897(3mg/kg)进行阻断后,5min后大鼠脑内纹状体中药物[18F]5b的SUVs下降~39%,并且在5~60min内,ST的放射性摄取值均低于正常对照组,药物[18F]5b在大鼠脑内小脑区域的放射性摄取(SUV值)在经D3受体阻断剂BP897阻断后,5~60min内的放射性摄取值也明显下降。该结果进一步表明,药物[18F]5b在活体动物脑内对多巴胺D3受体具有特异性摄取。
显然,上述实施例仅仅是为清楚地说明所作的举例,而并非对实施方式的限定。对于所属领域的普通技术人员来说,在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
