Abstract

本发明涉及表现出抗纤维化活性的取代的肉桂酰基邻氨基苯甲酸化合物或其衍生物、其类似物、其可药用盐、以及其代谢物,前提是所述化合物不是曲尼司特。

Description

治疗性化合物
技术领域
本发明涉及用于治疗医学病症的化合物。本发明还涉及所述化合物用于治疗医学病症(特别是与组织纤维化相关的病症)的用途。 
背景技术
曲尼司特(n-[3,4-二甲氧基肉桂酰基]邻氨基苯甲酸)是一种在日本用于治疗纤维化皮肤病症(如瘢痕疙瘩[8]和硬皮病[9])的抗纤维化剂。虽然还未完全了解曲尼司特精确的作用机制和方式,但其抑制ERK磷酸化(TGF-β信号通路中的一种主要中间体)的能力[20]可能是其抗纤维化作用的基础,已知曲尼司特的作用包括抑制多种细胞类型内的TGF-β诱导的细胞外基质产生[10,11,14,16]。利用糖尿病性心脏病的实验模型还已经表明曲尼司特减少心脏成纤维细胞中TGF-β诱导的胶原的合成[15]。 
纤维化是一种常见的对可导致器官功能障碍的各种组织损伤的响应。以此病理性纤维化为特征的疾病包括肝硬化、肺间质纤维化、肾小球肾炎、心力衰竭(缺血性和非缺血性的)、糖尿病性肾病、硬皮病、手术或装置插入后瘢痕组织增生、进行性肾病、肾小球肾炎、高血压、由于缺血性心脏病引起的心力衰竭、心脏瓣膜病或高血压性心脏病和肥厚性瘢痕。此外,病理性基质的精细加工还在纤维增生性肿瘤的发展和转移中发挥着作用。 
糖尿病患者发生心力衰竭的风险增加2至5倍[1]。除了缺血性心脏病以外,糖尿病中的心力衰竭也与心肌病相关,而与冠状动脉疾病无关[2]。所谓的“糖尿病性心肌病”的组织学特征在于伴有心肌弹性降低、收缩性受损和明显的心脏功能障碍的心肌纤维化[3-6]。因此,有人建议将减少细胞外基质的病理性积聚的策略作为治疗和预防糖尿病和非糖尿病状态中心力衰竭的可能疗法[7]。 
当前对于慢性心力衰竭的治疗集中在对通常响应于形成中的功能异常而产生的神经激素活化的调节上。然而,尽管常联用这样的治疗,但在大多数患者中心脏功能障碍仍持续发展。考虑到病理性纤维化在不利 的心脏重构(cardiac remodelling)中的重要性,已有人提出了抗纤维化剂的可能作用[16]。在超过十年的时间中所进行的研究一贯表明了prosclerotic生长因子、转化生长因子-β(TGF-β)在器官纤维化和功能障碍中具有重要作用[17],使得阻断其表达和作用代表了重要的治疗目标。 
还表明了曲尼司特可减少变态性疾病(例如变态性鼻炎和支气管哮喘等)中的炎症[42]。 
此外,还显示了曲尼司特具有抗增殖活性[43,44]。 
然而,近来已表明[19],在某些患者中遗传因素(尤其是吉尔伯特综合征UGT1A1变体)给予了对曲尼司特诱导的高胆红素血症的易感性。这种高胆红素血症可能与曲尼司特本身或以下曲尼司特代谢物的体内形成有关: 
提供具有潜在的抗纤维化、抗炎和抗增殖或抗肿瘤活性的其它化合物用于治疗或预防与纤维化疾病(以炎症和肿瘤疾病(良性和恶性的)为特征)相关的疾病、以及作为曲尼司特的替代物/佐剂可能是有用的。 
本发明的一个目的是克服或者至少减轻一个或多个与现有技术相关的难点和/或缺陷。

实施例2 
细胞培养研究-转化生长因子β刺激 
通过测量转化生长因子β刺激后的脯氨酸掺入来检测3-甲氧基-4-炔丙基氧基苯甲醛(FT011)在肾脏细胞系中的抗纤维化作用。 
使用从Sprague-Dawley大鼠中分离出来的30代至40代的充分表征的克隆肾小球系膜细胞系(1097)[30]。在加湿的5%CO2气氛下于37℃下将细胞培养在含有热灭活胎牛血清(FBS)、100μ/mL青霉素和100μg/mL链霉素的Dulbecco′s Modified Eagle′s(DME)培养基(Invitrogen,Grand Island,NY)中。 
为比较曲尼司特和FT011在体外对胶原产生的作用,采用了氚化脯氨酸掺入法[40]。将肾小球系膜细胞以低密度铺板于24孔培养板的DME/5%FBS中并使之贴附过夜。使亚汇合的细胞在DME/0.5%FBS和150mM L-抗坏血酸(Sigma-Aldrich)中饥饿处理过夜。然后将曲尼 司特或FT011加入到板孔中,4小时后加入0.5μCi/孔的L-[2,3,4,5-3H]-脯氨酸(Amersham)和5ng/ml的TGF-β1(R&D systems)。在刺激后48小时收获肾小球系膜细胞,以冰冷的PBS洗涤三次,与10%三氯乙酸(TCA)在冰上一起培育30分钟,然后以冰冷的10%TCA洗涤。然后将细胞溶解于750ml 1M的NaOH中。取利用500mL 1M HCl中和的500mL份的溶解细胞在10mL Instagel Plus闪烁体(Perkin-Elmer,Boston,MA)中进行闪烁计数。 
图1和图2所示的数据表明,在肾脏的肾小球系膜细胞中曲尼司特和FT011均在30~100μM内显著降低脯氨酸掺入。体外脯氨酸掺入的程度与体内纤维化的程度相关联。 
实施例3 
血小板来源的生长因子(PDGF)可刺激基质合成。因此,将肾小球系膜细胞与PDGF一起培育将证实脯氨酸掺入,所述脯氨酸掺入是基质合成的标志并由此成为纤维化的模型。 
为评价FT011对PDGF刺激的基质合成的作用,在PDGF存在下将肾小球系膜细胞(根据实施例2所述进行制备)与FT011或曲尼司特一起培育。本分析的结果见图3。如图3所示,在30和100μM的浓度下FT011抑制PDGF刺激的基质合成(通过降低的脯氨酸掺入而表明)。在30μM的浓度下,FT011在降低脯氨酸掺入方面比曲尼司特更有效。 
实施例4 
血管紧张素II或转化生长因子β(TGF-β)可刺激基质合成。因此,将新生的心脏成纤维细胞与血管紧张素II或TGF-β一起培育将会证实脯氨酸掺入,所述脯氨酸掺入是基质合成的标志并由此成为纤维化的模型。 
通过酶消化从一日龄幼鼠中分离出新生SD大鼠的心脏成纤维细胞(NCF)。将NCF通过percoll梯度纯化并接种在含有1%抗生素/抗真菌剂(AB/AM)和10%胎牛血清(FBS)的DMEM中。然后当汇合度达到约80%时对NCF进行传代。将第二代NCF用于测试。 
将NCF以25,000个细胞/孔接种在12孔板中并在37℃和5%CO2下于含有1%AB/AM和10%FBS的DMEM中培育过夜。然后以DMEM清洗细胞,然后以含有1%AB/AM、0.5%胎牛血清白蛋白(BSA)和维生素C的DMEM/F12替换所述培养基,随后在37℃和5%CO2下培育24小时。 
研究了FT011对新生SD大鼠心脏成纤维细胞中TGF-β或血管紧张素II刺激的纤维化的作用。如图4所示,FT011抑制大鼠新生心脏成纤维细胞中TGF-β刺激的纤维化(通过脯氨酸掺入表示)。如图3所示,FT011抑制新生心脏成纤维细胞中血管紧张素II刺激的纤维化(通过脯氨酸掺入表示)。

脯氨酸掺入 
在加湿的5%CO2气氛和37℃下,将充分表征的克隆的大鼠肾脏肾小球系膜细胞系[30](D Nikolic-Patterson馈赠)培养于含有FBS、100U/mL青霉素和100ug/mL链霉素的DMEM中。以低密度将细胞铺板于DMEM/10%FBS的24孔培养皿中并使之贴附过夜。使用20代至40代的细胞。使亚汇合的细胞在含有150uM L-抗坏血酸的DMEM/0.1%FBS中饥饿处理过夜,然后进行4小时的预处理(含有或不含有曲尼司特或FT化合物),然后加入5ng/mL的rhTGF-β11(R&DSystems)和1uCi/mL的L-(2,3,4,5-3H)-脯氨酸。对照孔中含有所述化合物但不加入TGF-β1。再将细胞培育44小时,在此期间目视监测它们的外观。然后将细胞在冰冷的PBS中清洗三次,在冰冷的10%TCA中清洗两次,并在37℃下于750μL 1M的NaOH中溶解45分钟或者在4℃下过夜。取500μL份,利用500μL 1M的HCl中和,加入10mL闪烁流体(Instagel Plus-Perkin-Elmer)。在β计数器上进行计数。 
将脯氨酸掺入计数归一化以考虑TGF-β1的增殖作用,对100至150μL份的剩余的溶解细胞进行BioRad蛋白测定。在测定前利用等量 的1M HCl中和样品。向用于建立标准曲线的BSA标准品中加入与存在于待测定样品中等量的1M NaOH和1M HCl。 
以cpm/μg蛋白质表示脯氨酸掺入。为比较测定间结果,以TGF刺激的脯氨酸掺入的降低百分数表示所述掺入,其中TGF单独给出0%的降低,零对照给出100%的降低。 
MTT检测 
将肾小球系膜细胞以15000个细胞/孔铺板于96孔培养皿的DMEM/10%FBS中并使之贴附过夜。在进行4小时预处理(含有或不含有曲尼司特或FT化合物)前,使亚汇合的细胞在DMEM/0.1%FBS中饥饿处理过夜。在添加了5ng/mL的rhTGF-β1后,使细胞在加湿的5%CO2气氛下于37℃下培育44小时。向对照孔中加入所述化合物,但不加入TGF-β1。除去每个孔中的培养基并向每个孔中加入在饥饿处理培养基(starve medium)中的100μL MTT(0.5mg/mL)。再使这些板在37℃下培育4小时。然后除去培养基,以100μL异丙醇替换,并在37℃下培育20~30分钟,直到蓝色甲臜晶体已溶解。在570nm波长下测量吸收度,同时扣除690nm的背景。

实施例6 
方法 
新生大鼠心肌细胞和成纤维细胞培养 
如之前所详细描述通过酶消化从一日龄幼鼠中分离出新生SD大鼠心肌细胞(NCM)和成纤维细胞(NCF)[20,21]。将NCF接种并保持在含有1%抗生素/抗真菌剂(AB/AM)和10%胎牛血清(FBS)(JRHbiosciences,Kansas,USA)的高葡萄糖(25mmol/L)Dulbecco′s Modified  Eagle′s培养基(DMEM)(Invitrogen Mount Waverley,Vic,Australia)中。使用第二代的NCF[31]。如前所述,将纯化后的NCM以1000个 细胞/mm2接种到6孔板中,然后保持在不含血清的补充胰岛素和运铁蛋白的DMEM(Invitrogen,NY,USA)中(4)。在最初3天内加入溴脱氧尿苷,向培养基中加入50mmol/L KCl以防止铺板的NCM的自发性收缩特性[32]。 
新生大鼠心肌细胞肥大的测量 
如前所述进行NCM肥大的研究[请提供该参考文献的细节][22]。利用化合物(浓度为1~30μM)处理后4小时,使用ANG II(10-7mol/L)来刺激肥大。在刺激60小时后,收获细胞,肥大定义为在不存在DNA含量(Burton测定法)的任何显著变化的情况下蛋白质含量(Bradford测定法)显著增加[33]。 
新生大鼠心脏成纤维细胞中胶原合成和增殖以及细胞活力的测量 
如前所述进行NCF胶原的合成测定[31]。简而言之,以密度为50,000个细胞/孔将NCF铺板于12孔板中并培育过夜。然后使NCF在高葡萄糖DMEM中进行血清饥饿处理24小时。然后在利用2×10-10mol/L的TGF-β1或10-7mol/L的ANG II进行刺激之前,将细胞在存在或不存在化合物(1~30μM)的情形下于新鲜DMEM/F12中预培育30分钟。 
对于胶原合成而言,向每孔中加入1μCi的[3H]-脯氨酸并在收获之前再培育48小时。通过利用10%TCA在冰上沉淀30分钟而收获细胞,然后利用0.75mL 1mol/L的NaOH在4℃过夜而溶解。然后利用1mol/LHCl中和样品,利用10ml闪烁流体在β计数器上计算3H水平而测定[3H]-脯氨酸掺入。 
对于增殖研究而言,在收获前2小时,利用加入到每孔中的1mCi的[3H]-胸腺嘧啶处理NCF。如前面胶原合成中所述,通过TCA沉淀法收获细胞,测定[3H]-胸腺嘧啶掺入。

心肌梗塞或糖尿病性肾病后FT011处理 
FT011是抗炎剂和抗纤维化剂 
方法 
动物 
本动物研究是在St Vincent′s医院的动物福利和伦理委员会以及澳大利亚国家健康与医学研究基金会的的批准下进行的。所有大鼠接受大鼠的常规食物(鉴定的啮齿类食物#5002,LabDiet,USA)并且自由饮水。所有动物置于稳定环境中,该环境保持22±1℃,从早上6点钟开始12小时的光亮/黑暗循环。 
试验研究(毒性评价) 
将总共20只重量为200~250g的雄性Sprague-Dawley(SD)大鼠随机分到剂量为50mg/kg/天、100mg/kg/天、200mg/kg/天和400mg/kg/天的FT011(Fibrotech Therapeutics Pty Ltd,Melbourne,Australia)组或曲尼司特(Pharm Chemical,Shanghai Lansheng Corporation,中国)组中,每日管饲两次(n=2-3只/组)。对照组动物管饲载体(1%羧甲基纤维素)。本研究进行2周。每日在经口管饲后1、4和8小时给动物采血以测量血浆浓度。还在研究结束时采集血清以评价肾功能和肝功能(血浆肌酸和尿酸盐、ALT和胆红素)。在研究结束时将大鼠单独置于代谢笼中,适应2至3小时,并在24小时内收集尿。在本研究期间,动物可持续得到自来水和标准实验室食物。生物化学试验是在StVincent′s医院病理系进行的。收获包括肺、心脏、肝、脾和肾在内的主要器官,并利用10%中性缓冲福尔马林浸没固定,然后包埋于石蜡中用于随后的光学显微镜检查。 
心肌梗塞大鼠 
将40只重量为200~250g的雄性SD大鼠随即分配到两组中,每组20只动物,各自进行手术。通过3%异氟烷/97%氧以1ml/100g体重的潮气量和72次呼吸/分钟的速率进行麻醉。对20只大鼠进行左前降支冠状动脉(LAD)结扎以诱导前壁心肌梗塞(MI)。简而言之,在无菌状态下于加热的台面(37℃)上进行手术以在处理过程中维持体温。利用在70%乙醇中的氯己定擦拭胸部以给该区域消毒。切开皮肤至胸骨左侧,钝性剥离下面的肌肉层。通过第四至第五肋间隙进行开胸术并利用牵开器(retractor)撑开肋骨,使得能够抵达心脏。撕开围绕心脏的围心囊并利用6-0普理灵(prolene)缝线迅速结扎LAD。左心室前壁明显发白和运动功能减退以及左心房膨胀是成功结扎的标志。除了缝线经过LAD下方的心肌层而没有结扎以外,对对照组(假手术+载体、假手术+FT011)进行由同样步骤组成的假手术操作[34]。 
在手术后第2天对所有动物进行超声心动图检查并将其随机分配到假手术组和MI组中。在手术后第7天将动物再次进行随机分配(每组10只动物)以接受载体或TT011(100mg/kg,每日两次,管饲法)。每周利用非侵入式血压(NIBP)控制器和Powerlab(AD instruments,NSW,Australia)通过尾套体积描记法(tail-cuff plethysmography)测 定预热的有意识大鼠的收缩压(SBP)。在手术后第35天进行处死之前通过超声心动图和心脏导管插入评价所有动物的心脏功能[34]。糖尿病(mRen-2)27大鼠 
禁食过夜后,指派40只6周龄的雌性杂交(mRen-2)27大鼠(St.Vincent′s医院动物房,Melbourne,Australia)通过尾静脉注射接受以下中之一:稀释于0.1M柠檬酸盐缓冲液(pH 4.5)中的55mg/kg的STZ(Sigma,St.Louis,USA)、或单独的柠檬酸盐缓冲液(非致糖尿病的)。然后将对照组和糖尿病组各自随机分配到2组(n=10)中,接受以下任一种处理16周:FT 011(100mg/kg,每日两次,管饲法,FibrotechTherapeutics Pty Ltd,Melbourne,Australia)或不进行处理。在注射STZ或柠檬酸盐缓冲液的24小时内开始处理。每周给大鼠称重并测量其血液葡萄糖水平(Accu-check Advantage II型血液葡萄糖监测仪,RocheDiagnostics,USA),仅血液葡萄糖>15mmol/L的STZ处理的动物才认为是糖尿病动物。每四周利用非侵入性血压(NIBP)控制器和Powerlab(AD instruments,NSW,Australia)通过尾套体积描记法(tail-cuffplethysmography)测定预热的有意识大鼠的收缩压(SBP)。在研究结束时通过HPLC测定血红蛋白A1c(HbA1c)。糖尿病大鼠接受每日注射胰岛素(腹膜内注射2-4单位;Humulin NPH,EIi Lilly and Co.,Indianapolis,IN)以降低死亡率并促进重量增加[37,39]。 
心脏功能 
超声心动图 
采用10MHz相控阵探头(phased array probe),使用Vivid 7Dimension(GE Vingmed,Horten,Norway)超声心动图仪进行超声心动图,包括多普勒检查。同时获取超声心动图数据。舒张末期定义为R波的峰值,收缩末期定义为T波的终点。 
通过腹膜内(i.p.)注射60mg/kg戊巴比妥钠使动物麻醉。使动物以左侧卧位接受超声心动检查。在乳突肌的水平面上使用胸骨旁短轴观进行M型超声心动图。在心舒期(d)和心缩期(s)期间获得左心室后壁(LVPW)和前壁(LVAW)的厚度,为舒张末期(LVIDd)和收 缩末期(LVIDs)的左心室固有直径。从胸骨旁短轴观来看,测量了心舒末期和心缩末期的血池横断面积(cross sectional blood pool area)。然后根据下式计算面积变化分数(FAC): 
FAC=[(舒张末期面积-收缩末期面积)/舒张末期面积]*100 
利用脉冲多普勒(样品体积2mm,置于二尖瓣叶的顶端),使用心尖四腔观(apical 4-chamber view)评价早期和晚期透壁心舒峰值流速(E波和A波)。以200mm/s的扫描速度记录10个心动周期的所有多普勒图谱。利用3次心跳的平均值评价所有参数,根据美国超声心动图协会(American Society of Echocardiography)指南[41]进行计算。获取所有数据并由单盲观测者利用EchoPAC(GE Vingmed)离线处理进行分析。 
心脏导管插入 
在超声心动图之后,将动物置于温垫(37℃)上,利用规格为14的导管进行插管,并利用室内空气采用10%体重潮气量以每分钟70次呼吸进行正压通气。将动物以侧卧位固定并向右颈静脉内插管,以每小时100μL输注0.9%NaCl。在导管(SPR-838型,Millar instruments,Houston,TX)于0.9%NaCl中和37℃下温热30分钟后校准压力。然后辨别出右颈内动脉并进行颅侧结扎。将2F小型化联合导管-微压计(2Fminiaturized combined conductance catheter-micromanometer)插入到颈动脉中以获取主动脉血压,然后向前进入左心室中直到获得稳定的压力容积(PV)环。然后打开腹部并辨别出下腔静脉和门静脉。将弹性带围绕这些血管放置以使得心脏前负荷迅速降低。在通气机关闭5~10秒钟并且动物呼吸暂停的情况下获取所有的环。 
然后利用压力传导性数据计算功能参数(Millar分析软件PVAN3.4)。这些参数包括舒张末压力容积关系(EDPVR)的斜率以及前负荷再充盈博功(PRSW)关系(定义为博功和末舒张期容积之间的关系,其中博功是每次心跳的压力-容积环的面积)的斜率。 
肾功能 
在4、8、12和16周时将大鼠单独置于代谢笼中,使之适应2~3 小时,收集24小时期间的尿。在本研究期间,动物可持续得到自来水和标准实验室食物。在代谢笼中24小时后,从24小时时的尿样中采集等量的尿样(5mL)并贮存于-70℃下,用于随后通过如前述的放射免疫测定进行白蛋白分析[36]。在处死之前,将99Tc-DTPA单次注射进尾静脉中来测量肾小球滤过率(GFR),并且如前所述在43分钟后取血样[37]。 
组织制备 
将大鼠麻醉(腹膜内注射60mg/kg体重戊巴比妥(Nembutal),Boehringer-lngelheim,Australia)。分离出肺、左心室(LV)、右心室(RV)和心房,一次性吸干并称重,然后迅速将LV进行切片,将组织新鲜冷冻、冷冻贮存于OCT中或者将组织固定在中性缓冲福尔马林中。将肾脏切下,去膜,横向切开,将一半肾迅速冷冻用于组织RNA测定,将另一半浸没在福尔马林中固定并用石蜡包埋用于随后的光学显微评价。 
组织病理学和免疫组织化学 
通过盲式方案(masked protocol)评价肾和心的组织病理学变化。利用苏木精和伊红(H&E)、过碘酸Schiff染色(PAS)、苦味酸天狼星红(picrosirius red)和/或改良Masson三色染色法对切片进行染色来显示胶原基质。 
梗塞面积 
在光学显微镜下检查心脏的苦味酸天狼星红染色切片并使之数字化,然后利用图像分析(AIS,图像分析工作站6.0版本,Ontario,Canada)进行分析。对梗塞面积进行形态学评价并计算为心内膜与心外膜周长与心内膜和心外膜的LV平均周长的比,如前所述。 
肾小球硬化指数 
在盲式方案中,检查大鼠的PAS染色的4μm肾切片中的150~200个肾小球。如前所述[39]对每个肾小球中硬化的程度进行0~4级的评级,0级:正常;1级:硬化面积多达25%(最小);2级:硬化面积为25-50%(中等);3级:硬化面积为50-75%(中等至重度);4级:硬化面积为 75-100%(重度)。然后利用下式(4)计算肾小球硬化指数(GSI): 
GSI = Σ i = 0 4 Fi ( i ) ,
其中Fi是具有给定级数(i)的大鼠中肾小球的百分数。 
基质沉积的定量 
为检查心脏中细胞外基质的沉积,利用苦味酸天狼星红将切片染色,然后以盲式(blinded manner)利用Lal等所述技术(Lal等,2004))的修正方法将未梗塞区域(NIZ)内的积聚的基质进行定量。简而言之,数字化捕获5片来自中左心室的随机染色的切片并然后加载到PentiumIII IBM计算机中。为使NIZ从梗塞区域和梗塞周围区域中分离出来,除去梗塞区域及其任一侧2mm区域。为评价肾脏中肾小管间质纤维化,利用改良Masson三色染色法将切片染色。简而言之,捕获5片来自每组10只大鼠的未交叠区域并利用与Fujix HC5000数码相机相连的BX50显微镜进行数字化。然后如上所述将数字图片加载到Pentium IIIIBM计算机中。选择分别用苦味酸天狼星红和三色染色法进行染色的切片上心脏中的红色区域和肾脏中的蓝色区域用作其颜色范围,然后定量该颜色范围的组织的面积比例。然后利用图像分析(AIS,图像分析工作站6.0版本,Ontario,Canada)来确定染成红色和蓝色的面积比例(基质)的计算[37,39]。 
免疫组织化学 
胶原亚型I和III 
利用山羊和小鼠的抗I型胶原抗体(Southern BiotechnologyAssociates,Inc.Birmingham,AL 35226USA)和抗III型胶原抗体(Biogenex,San Ramon Cal 94583USA)评价心脏中的胶原亚型I和III。简而言之,将4微米的切片置于溶蜡剂(histosol)中以除去石蜡,在梯度乙醇中再水化,并浸入自来水中,然后与正常山羊血清(NGS)(以0.1mol/L PBS(pH 7.4)稀释成1∶10)一起培育20分钟。在4℃下将切片分别与一级抗体一起培育过夜(18小时)。第2天,将所述切 片以PBS充分清洗(3×5分钟),与3%过氧化氢一起培育10分钟以阻断内源性过氧化物,然后以PBS冲洗(2×5分钟),与生物素化的猪抗山羊或羊抗小鼠IgG抗体(DAKO,Carpinteria CA)(以PBS稀释为1∶200)一起培育。然后以PBS冲洗切片(2×5分钟),随后将切片与抗生物素蛋白-生物素过氧化物酶复合物(Vector,Burlingame,CA)(以PBS稀释为1∶200)一起培育。在以PBS冲洗(2×5分钟)后,使用二氨基联苯胺四盐酸盐作为发色团对过氧化物酶缀合物定位1~3分钟。将切片以自来水冲洗5分钟以终止反应,然后以Mayer′s苏木精进行复染,在Scott′s自来水中进行分化,脱水,清洗并以Depex封片。将切片与1∶10的NGS而不是一抗血清一起培育,作为阴性对照。利用计算机辅助图像分析对积聚的I型胶原和III型胶原的免疫染色进行定量。简而言之,捕获来自每组10只大鼠的10个随机的未交叠视野并如上所述进行数字化。选择免疫染色切片上的褐色区域(I型胶原和III型胶原)用作其颜色范围。为校正由于收缩而导致的变化,如前报道利用计算机辅助图像分析(AIS,图像分析工作站6.0版本,Ontario,Canada)确定相对于总面积(基质+肌细胞)的免疫染色为阳性的面积(胶原/组织面积)[40]。 
巨噬细胞 
将4微米的心脏切片置于溶蜡剂中以除去石蜡,在梯度乙醇中水化并浸入自来水中,然后与正常山羊血清(NGS)(以0.1M PBS(pH 7.4)稀释成1∶10)一起培育20分钟。然后在4℃下将切片与特异性的一级单克隆大鼠巨噬细胞标志物(ED-1,1∶200Serotec,Raleigh NC,USA)一起培育18小时。通过在200倍光学显微镜下计数每组(n=10每组)中每只动物的10个视野中巨噬细胞的数目(以每视野中数目表示)来评估巨噬细胞的数目[38]。 
统计学 
除非另外说明,数据以平均值±标准误差(sem)表示。通过两因素方差分析利用Fishers事后比较测定统计学意义。蛋白尿呈偏斜分布,在对数转换之后对其进行分析,以几何平均值×/÷耐受因子表示。在Apple Macintosh G4计算机(Apple Computer,Inc.,Cupertino,California)上利用Statview II+图形软件包(Abacus Concepts, Berkeley,California)进行分析。P值<0.05认为有统计学意义。 
结果 
FT011试验研究(毒性评价) 
在体内试验研究中,所有动物组的体重都没有变化(表1)。在所有剂量下,肌酐和尿酸盐、ALT和胆红素的血浆水平都与对照大鼠相似(表1)。在管饲FT011后,所测的FT011血浆水平呈剂量依赖方式增加(图1)。还测量了以FT011处理的大鼠的尿中FT011的显著水平(图2)。

[0699] 利用FT011处理的心肌梗塞后大鼠 
动物特征 
在心肌梗塞后的大鼠中,RV/体重比和肺/体重比增加。肺/体重比的增加(是继发于左心衰竭的肺水肿的标志)可通过FT011处理而显著降低(表2)。

*P<0.05与假手术组相比;#p<0.05,与MI+载体组相比 
心脏结构 
在处理的MI组和未处理的MI组中,心肌梗塞面积相似(图23;P=0.36)。与假手术大鼠相比,MI大鼠显示间质性纤维化增加,其证据在于Masson三色染色法(图24和25)以及在非梗塞区域(NIZ)中有较大量的间质性心脏纤维状胶原亚型I和III(图26和27)。MI动物还显示NIZ中巨噬细胞浸润增加(图28和29)。所有这些变化都通过FT011处理而减少,标志着MI后不利的重构作用(remodelling)减小。 
超声心动图 
MI后,在本研究的5周持续时间内,超声心动图证实了不利的LV重构作用的标志分别包括:心室扩张,其证据在于LVIDd和LVIDs的增加;受损的收缩功能和舒张功能,其证据在于面积变化分数(FAC)百分率降低;以及E∶A比和减速时间(deceleration time)增加(表3)。所有这些变化都通过FT011处理而显著减少(表3)。 
体内压力容积环分析 
利用压力容积环分析来评价收缩功能和舒张功能的负荷敏感性度 量和非负荷敏感性度量。 
当与假手术组相比时,MI动物中的前负荷再充盈搏功指数(用来评价收缩功能)显著降低(p<0.05)。利用FT011进行处理保持了MI动物中的收缩功能(P<0.05)(表3)。 
当与假手术组相比时,MI动物中的腔室顺应性(通过舒张末期压力容积关系的斜率来度量)增加,这表明舒张功能受损。利用FT011进行处理使MI动物的顺应性恢复到了与假手术组可比的水平(图30)。
