Description
本申请是申请日为2013年06月04日、申请号为201380041609.7、发明名称为“含有马鞭草烯酮衍生物的神经退行性疾病治疗或者预防用药物组合物”的申请的分案申请。
技术领域
本发明涉及一种马鞭草烯酮衍生物的新用途,即治疗神经退行性疾病的用途,更具体地说,涉及一种神经退行性疾病的预防或者治疗用药物组合物以及利用上述组合物的神经退行性疾病的预防或者治疗方法,上述药物组合物含有具有兴奋细胞毒性引起的神经细胞凋亡抑制活性、氧化应激(oxidative stress)抑制活性以及血管内炎症细胞(巨噬细胞(macrophages)和嗜中性粒细胞(neutrophil))等细胞向脑损伤部位迁移(移动、迁移(migration)或者渗入(infiltration))的抑制活性的马鞭草烯酮衍生物或者及其盐。
背景技术
神经退行性疾病(degenerative brain disease)是一种脑神经细胞无法发挥自身功能而引发的衰老相关疾病,随着老龄化人口的急剧增加,社会对神经退行性疾病的关注不断增加。神经退行性疾病基于临床上表现的主要症状和被侵袭的脑部位进行分类,包括:阿尔茨海默病(Alzheimer's disease),帕金森病(Parkinson's disease)、亨廷顿氏舞蹈症(Huntington's disease)、多发性硬化症以及肌萎缩侧索硬化症(amyotrophiclateral sclerosis)等。
已知神经退行性疾病的引发原因有:对于脑神经系统的信息传达非常重要的脑神经细胞的凋亡、传达脑神经细胞和脑神经细胞之间信息的突触的形成或功能上的问题、脑神经的电活动的异常症状或减少等,但神经退行性疾病仍处于难以根源性治疗且病因尚不明确的状态。
最近,细胞分子学技术水平的提高使得神经退行性疾病的致病研究以及治疗剂开发活跃,并基于如下多种机理开发研究神经退行性疾病治疗剂:①胆碱作用的抑制、②NMDA(N-甲基-D-天冬氨酸:N-methyl-D-aspartate)受体拮抗机理、③β-淀粉样蛋白(β-amyloid)或者Tau蛋白代谢过程的分子-细胞生物学研究,β-淀粉样蛋白(β-amyloid)的致病蛋白质为抗原的疫苗开发和治疗抗体开发、④神经营养因子(neurotrophic factor)的表达诱导、⑤能够抑制致病蛋白质引发的神经细胞的氧化性损伤的抗氧化剂开发、以及⑥能够抑制炎症细胞的过度引入以及活性引发的炎症反应的抗炎剂开发等(Sonkusare etal.,Pharmacological Research,51(1),1-17,2005;Stanaione et al.,Ann 1st SuperSanita,47(1),49-54,2011;Halperin et al.,Neurotherapeutics,6(1),128-140,2009)。
作为胆碱作用的抑制剂的AChE抑制剂,通过抑制Ach的分解使得胆碱性神经传递物质的活性恢复,目前他克林(tarcrien)、多奈哌齐(donepezil)、利凡斯的明(rivastig分钟e)、加兰他敏(galanthamine)已得到FDA认可而处于市售中。
已确认氧化应激是阿尔茨海默病、帕金森病、亨廷顿氏舞蹈症等的中枢神经系统的神经退行性疾病的重要因素(Jin DQ et al,Biochemical and Biophysical ResearchCommunications,331,1264-1269,2005;Lim CS et al,Biological and PharmaceuticalBulletin,29,1212-1216,2006)。
2007年时,全世界有2500万名缺血性血管疾病患者(心肌梗死、脑中风、血栓症),预计2017年时增加至2800万名(DataMonitor公司,2007),大部分的OECD成员国中缺血性血管疾病(每10万名有226.6名,2004年)导致的死亡人数最多,癌疾病(165.6名)处于其次。脑中风分为以脑血管破裂引起的脑组织损伤为特征的出血性脑中风和供给于脑的血流流动被阻断而诱发脑梗死的缺血性脑中风。脑中风是与癌症争夺每年国内死亡原因中第一、第二位的发病率非常高的疾病(统计厅2002至2008年的资料),脑中风导致的国内死亡率已达到了OECD国家中的第二位。据2008年美国心脏协会(AHA)的报告,其为了治疗和控制缺血性血管疾病每年对脑中风支出了655亿美元的巨大费用,但实际情况是,脑中风治疗剂市场仅占居13亿美元。若几年内已证实效果的脑中风治疗药物上市,其将具有220亿美元以上的潜在的市场价值,因此,正积极地研究开发缺血性脑中风治疗剂。
在韩国,脑中风作为单一疾病占据死亡原因的第一位,相比于美国、加拿大、澳大利亚等先进国家显示出高的排名。脑中风导致运动、感觉功能的损伤以及记忆、学习、运算、推理等高层次功能的阻碍,从而会破坏生活质量,直至患者死亡对患者本人和家属带来很大的精神上、身体上的痛苦,并且,对于现代社会的老龄化趋势带来的老龄人口急速增加的最近状况而言,脑中风的发生和脑中风发生后生存期间的增加成为了社会性大问题。因此,需要开发出用于脑中风的症状减轻药物以及治疗药物。
但是,如上所述,尽管脑中风治疗存在临床重要性以及市场潜在价值等,但是,对于脑中风的治疗剂开发仍处于较弱水平,实际情况是,临床上许可的脑中风的治疗剂除了组织型纤溶酶原激活剂(tissue plasminogen activator:t-PA)以外没有其它治疗剂。脑中风由各种原因引发,包括脑梗死、脑出血、蛛网膜下出血等的致病原因各不相同的各种疾病。另外,脑中风由动脉硬化、脑淀粉样血管病、动脉夹层等各种脑血管疾病引发,心律失常或冠状动脉疾病引起的心源性栓塞症也会引发脑中风。虽然原因有多种,但是,在细胞生物学上认为是血液供给的降低以及其诱发的细胞凋亡等的相同机理,因此,作为开发脑中风的预防、调整以及治疗方法的基础的核心技术,在于理解缺血引起的脑细胞的凋亡机理。
为了防止脑疾病,国内外诸多研究者一直努力对这样的神经细胞的凋亡机理进行研究。脑中风的情况下,至今为止还没有开发出疗效显著的治疗剂,对于临床上使用的用于溶解脑血管中生成的血栓的唯一治疗剂即t-PA,很多临床医生担心其引发的脑出血等副作而用对其慎用。至今为止,很多研究者试图将针对兴奋性神经传递物质的谷氨酸受体的拮抗剂或抗氧化剂开发为缺血性脑中风治疗剂,但是,由于药效微弱或药物的毒性,全部以失败告终。
通常,患者发作脑中风之后到达医院急救室为止需要花费几小时,脑中风发作后几分种至几小时之内,过度的谷氨酸的游离引起的兴奋性神经毒性对神经细胞产生一次损伤,随着时间推移,露出在氧以及氮自由基的过度生成环境中,由此会受到二次损伤。经过几十小时之后,因炎症反应带来持续且严重的损伤,由此,事实上难以使用兴奋性神经毒性阻断物质,其使用临床上来说没有意义。
如上述所述,脑中风并不是单一原因造成的疾病,其是基于各种细胞凋亡的途径和机理而引发脑损伤的疾病。最近,试图通过使用具有相互不同机理的药物的复合处方来获得脑中风治疗的协同作用。例如,将阿司匹林和双嘧达莫(dipyridamole)同时给药时,相比于单独给药阿司匹林,能够使脑中风治疗的预后(prognosis)更好(Chatuvedi S.,ClinTherap,30(7),1196-205,2008),另外,17β-雌二醇(17β-Estradiol)和tPA的复合处方中,17β-雌二醇(17β-Estradiol)减少tPA给药引起的尿激酶(urokinase)、MMP2以及MMP9的表达增加产生的脑出血的副作用,由此在缺血性脑中风患者中显示出延长治疗时间段的效果(Liu R.et al.,J Pharmacol Exp Ther,332(3),1006-12,2010)。作为NMDA受体阻断物质的美金刚(Memantine)和作为β肾上腺素β2(beta 2)受体激动剂的克伦特罗(Clenbuterol)的复合给药在永久性局部缺血模型中显示出抑制缺血性脑损伤的协同效果(Culmsee C.etal.,Stroke,35(5),1197-202,2004),另外,美金刚(memantine)和作为钙离子阻断物质的托吡酯(Topiramate)的复合给药在新生大鼠中协同抑制低氧血症引发的脑损伤(Lie C.etal.,Brain Res,1282,173-82,2009)。但是,这些研究结果大部分是以缓和症状为目的,并未获得基于脑组织保护机理的协同效果。
为了理解缺血引起的脑组织的损伤并开发用于抑制其的药物,需要理解缺血后脑组织的损伤机理和途径。通常,缺血后脑细胞的损伤或凋亡由各种原因引起。例如,兴奋细胞毒性(excitotoxicity)、周边埂塞去极化(peri-infract depolarization)、氧化应激以及炎症等与缺血引起的脑损伤发作相关联(Dirnagl et al.,Trends Neurosci.,22,391-397,1999)。因此,需要理解缺血性脑损伤的复杂因素的各种状态及临时状态(例如,发病以及疾病程度),并需要适当阻断病理生理学上的瀑布(cascade)。
兴奋性细胞毒性引起的神经细胞凋亡可由谷氨酸受体拮抗剂抑制,谷氨酸起到作用的离子性受体是AMPA(α-氨基-3-羟基-5-甲基异恶唑-4-丙酸:α-amino-3-hydroxy-5-methyl-4-iso-xazolepropionic acid)、卡因酸(kainate)、NMDA(N-甲基-D-天冬氨酸:N-methyl-D-aspartate)的受体,特别是,针对细胞凋亡的NMDA受体活性研究较多(Standridge J.B.,Clin.Ther.,26(5),615-630,2004)。但是,相比于这些努力,NMDA受体阻断剂的药效微弱或有毒性,由此没有在临床试验上成功的例子。作为NMDA受体阻断剂的MK-801显著减少了缺血性脑损伤,但具有治疗时间窗(therapeutic time window)很短的大缺点,只有在大鼠以及沙土鼠(gerbils)中诱发的局部性缺血症发病之后的一小时之内施用MK-801时才会显示出保护神经细胞的效果(Margaill et al.,J Cereb Blood FlowMetab,16,107-113,1996;Hatfield RH et al.,Eur J Pharmacol,216,1-7,1992)。另外,虽然MK-801在缺血症发作之后延迟了神经细胞凋亡,但是,并未改善治疗数周后神经恢复或者最终存活率(Valtysson J.et al.,Acta Neurochir(Wien),129,58-63,1994;VonLubitz DK et al.,Eur J Pharmacol,233,95-100,1993)。作为兴奋性神经传递物质的谷氨酸的受体之中,与NMDA受体一起同时存在AMPA受体,针对该AMPA受体的拮抗剂在MCAO 28天之后也没有显示出神经功能缺损的显著保护效果(Colbourne F et al.,Stroke,30,662-668,1999)。NMDA或者AMPA受体拮抗剂等的短治疗范围以及短期治疗效果意味着这些受体仅在初期缺血症瀑布中起到短暂性作用,而不受拮抗剂影响的其它的病理生理过程被视为对后续脑缺血损伤带来影响。
与其它的各种退行性疾病相同,缺血性脑中风中氧化应激对细胞凋亡和功能丧失带来很大影响。由此,对利用抗氧化剂的缺血性脑中风治疗效果进行了积极的研究(SalamaM.et al.,Co-Enzyme Q10 to Treat Neurological Disorders:Basic Mechanisms,Clinical Outcomes,and Future Research Direction.CNS Neurol Disord DrugTargets.2013;Rodrigo R.et al.,Oxidative Stress and Pathophysiology ofIschemic Stroke:Novel Therapeutic Opportunities.CNS Neurol Disord DrugTargets.2013)。在日本,作为脑中风治疗剂市售的有以抗氧化效果为主机理的依达拉奉(Edaravone)(Firuzi O et al.,Curr Med Chem.,18(25),3871-88,2011;Yoshida H.etal.,CNS Drug Rev.,12(1),9-20.2006)。
缺血后兴奋性细胞毒性开始发作,经过几小时后,在脑损伤部位中开始引起炎症反应,其持续数日~数周使得脑损伤更加恶化。由此,最近试图利用抗炎剂来治疗缺血性脑中风(Price CJ et al.,J Neurol Neurosurg Psychiatry,74,1476-1484,2003;SalamaM,Co-Enzyme Q10 to Treat Neurological Disorders:Basic Mechanisms,ClinicalOutcomes,and Future Research Direction.CNS Neurol Disord Drug Targets.2013;Rodrigo R.et al.,Oxidative Stress and Pathophysiology of Ischemic Stroke:Novel Therapeutic Opportunities.CNS Neurol Disord Drug Targets.2013)。另外,最近有报告称,由血管流入的炎症细胞在缺血性脑中风中对脑损伤增大起到主要作用(KangGHet al.,J Neurol Sci.,15,318(1-2),25-30,2012;Choi IY et al.,Am J Pathol,179(4),2042-52,2012;Choi YK et al.,Free Radic Res.,44(8),925-35,2010;Choi IY etal.,Free Radic Res.,44(5),541-51,2010;Lee JC et al.,Glia,50(2),168-81,2005)。另外,还有报告称,大麻素(cannabinoid)B2受体介导抗炎症反应抑制缺血性脑组织的损伤(Choi IY et al.,Am J Pathol,182(3),928-39,2013)。
由此,可认为,为了脑中风的完全治疗,必须开发出具有各种细胞保护作用的药物。为了达到这样的目的,即,为了开发具有各种细胞保护机理的物质(多向治疗药物:pleiotrophic therapeutic drug),本发明人开发了(1S)-(-)-马鞭草烯酮(verbenone)的衍生物。(1S)-(-)-马鞭草烯酮(verbenone)是,通过小蠹虫(bark beetles)从寄主树树脂前体即a-蒎烯(pinene)生成出的天然抗-聚集信息素(anti-aggregation pheromone)。有报告称,含有(1S)-(-)-马鞭草烯酮的精油显示出抗菌作用、驱虫作用等生理活性(Bernarde WA,Z Naturforsch C,65,588-93,2010;Martinez-Velazquez M.,J MedEntomol,48,822-827,2011)。另外,WO2000/63159公开了马鞭草烯酮[(1S,5S)-4,6,6-三甲基二环[3.3.3]庚-3-烯-2-酮:(1S,5S)-4,6,6-trimethylbicyclo[3.3.3]hept-3-en-2one)]及其衍生物具有气道的抗炎症效果。
但是,上述文献的任意一处都没有公开或启示马鞭草烯酮衍生物的神经细胞凋亡降低效果、氧化应激降低效果、缺血性脑损伤抑制效果以及炎症细胞迁移抑制效果。
为此,本发明人等为了确认马鞭草烯酮衍生物对神经细胞凋亡降低、氧化应激降低、缺血性脑损伤(ischemic brain damage)以及炎症反应起到作用的效果,使用低氧性-缺血性大鼠模型测定了NMDA-诱导兴奋细胞毒性以及细胞死亡,并实施针对抗氧化活性的试验,由此最先确认到马鞭草烯酮衍生物具有神经退行性疾病治疗效果的事实。更加具体地说,本发明的马鞭草烯酮衍生物使神经细胞凋亡(neuronal cell death)以及氧化应激降低,并且实施体内(in vivo)试验的结果,确认到其显示出了优异的针对缺血性脑损伤以及炎症反应的抑制效果,以此完成了本发明。

实施例2.针对兴奋细胞毒性、抗氧化活性以及局部脑缺血症的马鞭草烯酮衍生物的效果
试验动物的准备
将公司(Charles River Laboratories公司,首尔(Seoul),韩国(Korea))供给的SD大鼠(260-270g,雄性),在维持12小时的明暗/循环周期并可自由接近饮用水的情况下,使其顺应在试验前环境后使用。该试验在NIH基准(美国国立卫生研究院的试验动物护理和使用指南:NIH Guide for the Care and Use of Laboratory Animals)以及委员会(高丽大学试验动物管理和使用委员会:Korea University Institutional Animal Care&UseCommittee)批准下实施。
统计处理
以平均数(means)±S.E.M.的形式处理数据(Data),并实施单向方差分析(one-way analysis of variance:ANOVA)而鉴定统计显著性,采用事后邦弗朗尼检验(post-hocbonferroni test)实施多重比较,P值<0.05判断为具有显著性。ANOVA分析之间,确认试验方法(Levene'sTest)对方差齐性(Equality of Variances)的P值(P>0.05)。必要时,对上述数据实施克鲁斯凯-沃利斯检验(Kruskal-Wallis test)之后,通过曼-惠特尼检验(Mann-Whitney test)进一步分析。
实施例2-1.马鞭草烯酮衍生物对兴奋细胞毒性的影响
为了确认上述实施例中获得的试料对兴奋细胞毒性带来的效果,应用文献中记载的方法实施如下试验(Ju C.et al.,BBRC,431(3),484-489,2013)。
(1)皮层神经细胞培养
从胚胎16~17天SD大鼠中获得皮层神经细胞(neuron)(5x 105细胞/ml)。即,切除脑皮层,使用移液管(巴氏吸管:Pasteur pipette)在缓冲液(汉克斯平衡盐溶液:Hanks’Balanced Salt Solution,HBSS)中反复实施滴定(trituration),由此分离细胞。将细胞悬浮液(1.8x103细胞/mm2)分配于板(多聚赖氨酸(poly-D-lysine)(100mg/ml)/层粘蛋白(laminin)(4mg/ml)-预处理板)上。初期,将细胞置于10%FBS-添加NBM培养基中,并维持在37℃温度、加湿的96%空气/5%CO2环境中。培养上述培养物15~16天之后实施试验。
(2)OGD(缺氧缺糖:Oxygen-Glucose Deprivation)后再氧化
为了诱导试验管低氧性-缺血性症状,将培养的细胞置于缺氧室(氧分压<2mmHg),为了去除上述培养物的残余氧,换成以缺氧性气体混合物(95%N2,5%CO2)充满(bubbling)的葡萄糖-去除培养基(glucose-free DMEM)并培养30分钟,为了缺氧(oxygendeprivation),在37℃温度下培养90分钟。90分钟后,将上述露出溶液换成含有氧化25mMol/L葡萄糖的DMEM培养基,中断OGD反应,使细胞恢复成正常氧条件。在提供好氧性混合气体(95%空气,5%CO2)的葡萄糖(25mMol/L)-含有DMEM培养基中保持未露出于OGD的对照细胞。从OGD/再氧化(re-oxygenation)30分钟之前开始用试料处理细胞并维持在整个实验期间。
(3)NMDA(N-甲基-D-天冬氨酸:N-methyl-D-aspartate)-诱导兴奋细胞毒性测定
在板上培养15-18天之后,在NMDA(100mM)的溶液(Mg2+-去除Earle’平衡盐溶液(Earle’s balanced salt solution:EBSS);含有1.8mM CaCl2以及10mM甘氨酸(glycine))中将皮层神经细胞露出10分钟。进行上述露出之后,用含有MgSO4的EBSS溶液洗涤细胞,在37℃温度、5%CO2条件下,在培养器中的25mmol/L葡萄糖含有DMEM培养基中进行培养。从NMDA处理30分钟之前开始用试料(10mM)处理细胞。
(4)细胞损伤或者细胞死亡的测定
细胞损伤或者细胞凋亡是利用细胞存活率测定试剂盒(Sigma-Aldrich公司,St.Louis,MO)测定从培养基中分泌的LDH量,细胞存活率是相对于总细胞LDH水平的LDH的百分率来表示,其中,所述总细胞LDH是冷冻并实验后溶解的姐妹培养物(sistercultures)中测定。
兴奋细胞毒性是缺血症-诱导神经细胞凋亡中的主要因素,特别是初期阶段脑缺血症中的主要因素之一。OGD是利用培养的皮层神经细胞模仿缺血症中的急剧破坏血流供给以及能量耗费的现象的实验模型,通过OGD诱导细胞损伤,促进如LDH那样的蛋白质向培养液中的分泌,并测定其来测定细胞膜损伤以及神经细胞损伤。试验结果,可确认化合物(3a,3c以及3f)能够显著降低神经细胞损伤,所降低程度达到了已知晓的作为NMDA受体拮抗剂的MK801的程度,并确认到未显示细胞毒性(图1)。
NMDA受体的过度刺激引发的兴奋性毒性(Excitotoxicity),是OGD/R期间的神经损伤以及自由基以及紧接的氧化应激的同时多发性引起的脑缺血性损伤相关主要因素。本实验结果表明,本发明的化合物(3a,3c,3f,3i以及5a),其虽未达到MK-801的抗-兴奋细胞毒性活性(anti-excitotoxic activities)程度,但其显著减少了培养的皮层神经细胞中的NMDA-诱发神经损伤(图2)。其意味着,本发明化合物对NMDA-诱发神经兴奋细胞毒性起到的抑制作用有助于抗-缺血活性。
实施例2-2.马鞭草烯酮衍生物的抗氧化活性效果
为了确认上述实施例中获得的试料的直接抗氧化活性,利用文献中记载的方法实施如下实验(Ju c.et al.,BBRC,431(3),484-489,2013;Huang D.et al.,J.Agric.FoodChem.,53,1841-1856,2005.)。
(1)活性氧(ROS)的细胞内水平测定(DCF荧光度)
为了确认试料的自由基直接消除活性,利用广泛用于再氧化(reoxygenation)1小时之后测定细胞内氧化应激的H2DCF-DA(2,7-二氢二氯荧光素二乙酸酯:2,7-dihydroichlorofluorescein diacetate)荧光指示剂进行染色,2小时之后在25mM葡萄糖(Glucose),1.8mM CaCal2,1.2mM MgSO4以及2.5mM丙磺舒(probenecid)(pH7.4)含有EBSS缓冲液中洗涤细胞,用读取仪器(荧光酶标仪:fluorescence microplate reader,SpectraMax GeminiEM;Ex=485nm,Em=530nm)或者数码相机(DFC420C,Leica,WetzlarGermany公司)、显微镜(荧光显微镜:fluorescence microscope;DM IL HC Fluo,Leica,Wetzlar,Germany公司)测定DCF的荧光度。荧光强度补正成自动荧光度(即,未搭载H2DCF-DA的细胞的荧光度)。
从本实验结果确认到,化合物3c以及3f能够减少OGD-诱导细胞内氧化应激(图3)。
(2)氮自由基去除能力测定(DPPH分析法)
将上述各试料,用DPPH(23.6μg/ml,在乙醇)混合试料,在37℃温度条件下,在暗处培养30分钟。在517nm下测定通过试料减少的DPPH吸光度。将维生素C(Vit.C;SigmaAldrich公司,St.Louis,MO)作为对照群使用,通过下述数学式1计算DPPH%抑制率(inhibitionvalue)。
数学式1
消除活性(%)=[Absmax(Vit.C)-Abssample]/[Absmax(Vit.C)-Absmin(Vit.C)]X100.
(3)氧自由基吸收能力(ORAC;oxygen radical absorbance capacity)测定
如下所述,通过文献记载的实验方式实施ORAC分析方法(Huang,D.et al.,J.Agric.Food Chem.,53,1841-56,2005)。
准备缓冲液(75mM磷酸盐缓冲液(phosphate buffer),pH7.4)中的AAPH(60mM)以及荧光素(fluorescein)(50nM),其中不存在试料或者标准液(水溶性维生素E:Trolox)。用50%丙酮中溶解的7%RMCD(randomly methylated beta-cyclodextrin)悬浮上述试料以及标准液来做准备。准备RMCD以用于提高脂溶性试料的溶解度。将荧光溶液(Fluoresceinsolution,66nM,190μl)与试料振荡5秒钟,从而使其充分混合。在37℃温度下培养10分钟后,迅速添加AAPH(500mM,30μl),对于荧光度的减少水平,利用读取机(荧光酶标仪:fluorescence microplate reader,Ex=485nm,Em=530nm;SpectraMax GeminiEM,Molecular Devices,Sunnyvale,CA),并通过37℃条件下9小时内每5分钟测定的方式进行测定。为了过氧化氢自由基(peroxyl radical)消除作用的定量化,对于消除活性而言,根据下述数学式2计算出AUC(曲线下面积:area-under-the-curve),根据数学式3计算出纯(net)AUC,根据trolox浓度增加制作出纯AUC的标准曲线(standard curve),并根据下述数学式4计算出试料的troloxe当量(TE;trolox equivalents)。
数学式2
AUC=(0.5+f1/f0+f2/f0+f3/f0+…+fn-2/f0+fn-1/f0+fn/f0)x5,
(其中,f0是0分钟时间(time)I下的最初荧光度。)
数学式3
纯(net)AUC=AUCsample-AUCblank.
数学式4
试料的trolox当量(TE;troloxequivalents)=[netAUCsample at25mM]/[netAUCtrolox at25mM]
通过实施下述两种不同形式的化学反应测定本发明的马鞭草烯酮衍生物的抗氧化活性:(1)单电子转移分析法(single electron transfer-based assay),即,对于自由基引发剂以及作为最终指示剂起到作用的DPPH减少进行测定的DPPH分析法(2,2-二(4-叔辛基苯基)-1-苦肼基自由基分析法:2,2-di(4-tert-octylphenyl)-1-picrylhydrazyl[DPPH]assay),以及(2)氢原子转移分析法(hydrogen atom transfer assay),即,氧自由基吸收能力分析法(oxygen radical absorbance capacity[ORAC]assay),测定称为AAPH(2,2'-偶氮双(2-甲基丙脒)二盐酸盐:2,2'-azobis-(2-methylpropionamide)-dihydrochloride)的过氧化氢自由基引发剂(peroxyl radical generator)和作为抗氧化剂起到作用的试料对于氧化性荧光指示剂(oxidizable fluorescent probe,fluorescein)起到的竞争性反应动力学作用。
从本实验结果确认到,DPPH分析法中,大部分的具有酚基的苯乙烯基衍生物(3a-f,3h-i)对于从DPPH转变至有机氮自由基(organic nitrogen free radicals)的变化显示出强烈且直接的消除活性(参考表1)。其中,化合物3c以及3f在相同浓度下显示出比维生素C更强的消除活性,ORAC分析法中,具有吡咯基的衍生物(4e)以及具有酚基的所有化合物(3a-i)显示出比trolox更强的过氧化氢自由基消除活性(表1以及表2)。苯基的间位(meta)以及对位(para)中导入羟基的化合物能够提高自由基消除活性。

利用面罩(mask)使N2O和O2(70:30v/v)混合物中以3.0%异氟烷(isoflurane)为起始维持2%异氟烷,以此对大鼠进行麻醉。整个实验过程中,直至从麻醉充分恢复的期间包括手术后期间内,利用直肠用温度计以及加热垫使体温调整和维持在37℃±0.3℃温度。用左侧血管内MCAO诱导局部脑缺血症,简单地说,将3-0热钝化(heat-blunted)单丝尼龙线(monofilament nylon suture;Ethicon,Johnson-Johnson,Brussels,Belgium)插入于右侧外部颈动脉切除部分内腔并向内测颈动脉插入17.5mm,以闭塞MCA小孔。1.5小时后去除上述缝合使动物恢复。对于手术-对照群,除了MCAO以外,实施相同的手术方法。在MCAO15分钟前以及再灌注15分钟之后测定生理学数值,对平均血压,用血压计(MicroMed,Lousville,KY)测定5分钟。用分析仪(Ciba Corning Diagnostics公司,Medfield,MA)测定血中pH、PaO2、PaCO2以及血糖数值。用DMSO溶解并用10%聚氧乙烯蓖麻油甘油醚(cremophore)以及灭菌盐水稀释的(5%)试料(3f衍生物),则MCAO诱导后2小时开始向大鼠腹腔内给药(100mg/kg)。
(2)埂塞体积的测定
再灌注后,用水合氯醛(3.5%chloral hydrate,5ml/kg,腹腔注射)麻醉大鼠之后处死。对于利用切片模具(大鼠脑切片模具:rat brain matrix,Ted Pella,Redding,CA)切断的脑动脉切片(2mm),用试剂(2%三苯基氯化四氮唑,Sigma-Aldrich公司,St.Louis,MO)在37℃温度下染色30分钟。用4%多聚甲醛(paraformaldehyde)(pH 7.4)进行固定,在30%蔗糖(sucrose at)4℃温度下,连续两天在30%蔗糖(sucrose)中进行冷冻保护。对于前囟的+4mm(前部)以及-6mm(后部)之间的埂塞切片,用分析程序(OPTIMAS5.1图像分析程序:image analysis program,BioScanInc公司.Edmonds,WA)进行测定。用于测定脑梗死大小的埂塞区域的外部周长是用手动实测。脑梗死总体积(mm3),是通过记载于文献(JNeurosci Methods(1998)84:9-16;J Cereb Blood Flow Metab(1990)10:290-293)中的方法,并根据下述数学式5补正为脑水肿而计算出。如下述数学式6所示,脑水肿是以同侧/反侧半球区域(ipsilateral(V1)/contralateral hemisphere area(Vc))的百分率增加率进行计算。全部用双盲试验法进行测定。
数学式5
脑梗死总体积(mm3)=用直接测定法测定的同侧性体积(IVd)x[(反侧性体积(Vc))/反侧性体积(Vc)](Total infraction volume(mm3)=ipsilateral volume(IVd)obtained by direct measurement x[(contralateral volume(Vc))/ipsilateralvolume(VI)])
数学式6
水肿体积(%)=[(同侧性体积(V1)反侧性体积(Vc))/反侧性体积(Vc)]×100(Edema volume)(%)=[(ipsilateral volume(VI)–contralateral volume(Vc))/contralateral volume(Vc)]×100.
之后冻结组织,用切断器(Leica 3050;Leica,Nussloch,Germany)切断成10或者30mm颈动脉切片,并在-20℃温度下进行保存。
(3)神经功能缺损的测定
缺血后24小时后测定神经功能缺损,通过文献(Stroke,17,472-476,1986)中记载的方法,以4点评定(4-point scale)方式进行测定(0:没有神经功能缺损,1:弯曲前脚,2:弯曲前脚以及对于侧面推压力表现抵抗力减少,不转动,3:与2相同,但转动)。
(4)脑组织免疫组织学染色
为了抑制非特异性抗体结合,对通过上述方法准备好的脑组织切片,用含有5%血清的缓冲液在常温下处理一小时。加入稀释成适当浓度的一次抗体(MPO抗体以及ED-1-抗体,各自1:100;硝基酪氨酸(Nitrotyrosine)抗体,1:50;IL-1a、IL-1b、TNF-a抗体各自1:100),在4℃温度下染色一晚。洗涤去除未结合的一次抗体之后,用结合有荧光标记的二次抗体在常温下染色一小时。洗涤去除未结合的二次抗体之后,用Hoechst 33258染色液对核进行20分钟染色,洗涤之后置于载玻片,使用共焦荧光显微镜(Zeiss LSM510;Zeiss,Oberkochen,德国)进行观察。
(5)血-脑屏障通透性实验
静脉内注射时,染色液(伊文思蓝染色液,2%)即刻结合于血清内白蛋白,转变成无法透过正常血脑屏障的高分子物质,但在诱导了脑缺血症的老鼠脑组织中,血-脑屏障被损伤,伊文思蓝的通透性提高,由此染色量会增加。用200ml的生理盐水对上述的诱发局部脑缺血症的老鼠实施心脏灌注。摘取脑组织,称重后浸渍于试剂(三氯乙酸,60%),在4℃温度下处理24小时。粉碎组织之后,在10000rpm下离心分离15分钟,取上清液,在610nm下测定脑组织内残存的伊文思蓝染色液的吸光度并定量,计算成每克组织的染色液量。
(6)长期存活率实验
对于上述的诱发局部脑缺血症的老鼠,手术后在与手术前相同条件下经过3周测定存活率以及神经功能缺损。
(7)栓塞性缺血脑中风动物模型
使用70%N2O和30%O2(v/v)的混合气体中混合的3%异氟烷(isoflurane)气体,吸入麻醉老鼠(体重270-300g之间)之后,利用3%异氟烷(isoflurane)维持。插入直肠温度计,使用连接于其的自动加热垫使手术期间老鼠的体温维持在37.0-37.9℃。颈部中切开正中线之后,分离右侧颈总动脉(common carotid artery:CCA)和右侧颈外动脉(externalcarotid artery:ECA)以及右侧颈内动脉(internal carotid artery:ICA),捆住颈外动脉和颈总动脉。使用弯曲的微血管夹暂时夹闭颈内动脉。将颈外动脉和颈内动脉的分支起始部分切开小口,为了便于进行血管注入,使用注入口外径缩小成0.3mm的外径0.58mm的PE-50导管,用装有生理盐水的100ul Hamilton注射器向颈内动脉内注入35mm栓塞物。除去微血管夹,将导管小心地向颈内动脉内推进16-17mm,移动至距中脑大动脉的起始点约2mm的位置。将导管的栓塞物注入至颈内动脉(10ul)。注入栓塞物5分钟之后,除去导管。在颈内动脉分支点中进行捆扎,缝合切除部位后,等老鼠从麻醉中清醒。实验中使用的栓塞物是,向PE-50管中迅速注入从老鼠中采取大腿动脉血,在常温下放置2小时、4℃温度下放置22小时而生成血栓。实验前切断管,使用装有生理盐水的附有23G注射针的1ml注射器,由PE-10管转移至变形PE-50导管。
上述实验的结果,确认在暂时性缺血诱导大鼠模型试验中,通过试料(3f,50mg/kg)的缺血后处理(Post-ischemic Treatment;腹腔注射;脑梗死后2小时以及7小时时给药,总共给药两次)方法,显著减少了缺血性损伤、脑水肿以及神经功能缺损(图4)。另外,通过在施用试料的老鼠获得的脑组织切片中对硝基酪氨酸实施免疫组织学染色,测定组织内抗氧化活性,其结果,确认了试料给药群中脑组织内抗氧化活性显著增加(图5)。
一方面,通过免疫组织学染色观察炎症细胞向脑梗死部位以及半阴影部位侵袭的情况,其结果,确认了能够显著抑制被MPO抗体染色的中性粒细胞/单核细胞和被ED-1抗体染色的活性化的小胶质细胞/巨噬细胞的迁移(图6)。除此之外,确认了如IL-1α(alpha)、IL-1β(beta)、TNF-α(alpha)等已知在缺血性损伤中承担重要作用的细胞因子的组织内表达量在试料给药群中显著减少(图7)。另外,还确认了显著减小了因缺血性损伤增加的血-脑屏障通透性(图8)。诱导暂时性缺血的老鼠模型中施用试料后,观察对长期存活率和神经功能缺损恢复率带来的影响3周的结果,确认了施用试料的老鼠的长期存活率以及神经功能缺损恢复率得到了显著提高(图9)。缺血性脑中风时,常有药物引起的出血增加的情况(例,tPA),其在临床上可能会增加患者的副作用(例,死亡或预后(prognosis)的恶化),因此需要注意。但是,本试料在由自体血液注入诱导缺血性脑中风的体内动物模型中,对脑损伤大小没有带来显著的影响,由此可视为发生上述副作用的可能性小(图10)。
