Abstract
本发明涉及显示白三烯B4受体2(BLT2)抑制活性的新颖化合物和包含其作为活性成分的用于预防或治疗炎症性疾病的药物组合物。在本发明中,研究了显示BTL2抑制活性的新颖化合物,并且通过实验证实了在该化合物中显示的增强癌细胞死亡、转移抑制和趋化运动抑制、抗哮喘活性效果。因此,本发明实现了用于治疗或预防炎症性疾病的更基本的基本方法和靶向治疗。
Description
技术领域
本发明涉及一种新颖化合物及其用途,更具体地说,涉及一种显示白三烯B4受体2(BLT2)抑制活性的新颖化合物和一种用于预防或治疗炎症性疾病的药物组合物,该药物组合物包括所述新颖化合物作为有效成分。
背景技术
炎症反应是由各种作用机制激活的人体免疫系统之一,用于抵抗应用于活体或组织的物理作用,化学物质,细菌感染或免疫刺激。但是,如果这种炎症反应持续存在,反而会促进对粘膜的损伤,因此已经注意到包括类风湿性关节炎、动脉粥样硬化、胃炎、哮喘等在内的炎症性疾病是由红斑、发热、肿胀、疼痛或功能障碍引起的。随着时间的推移,这种炎症反应分为急性炎症和慢性炎症。急性炎症是持续数日至数周的炎症反应,并引起诸如红斑、发热、疼痛或肿胀的症状,而慢性炎症是数年至数十年的长期炎症状态,并涉及由单核细胞浸润引起的诸如纤维化的组织学变化或组织破坏,成纤维细胞或毛细血管增殖,或结缔组织增多。
具体而言,当对生物体施加炎症刺激时,组胺、缓激肽、前列腺素、一氧化氮(NO)、所有类型的促炎细胞因子等被局部地合成并分泌,并引起红斑、发烧、疼痛、或肿胀以及血管舒张。特别是在体内的炎症中,除了例如干扰素-γ(INF-γ)、肿瘤坏死因子-α(TNF-α)、白细胞介素-1(IL-1)和白细胞介素-6(IL-6)等细胞因子之类常见的免疫因子以外,一氧化氮(NO)和前列腺素E2(PGE2)也是众所周知的主要促炎物质。
传统上,炎症反应的终止被认为是由于启动炎症的物质水平降低而自然且被动地发生的现象,但发现炎症的终止被脂氧素(lipoxin),消退素(resolvin)或保护素积极地促进,其是Serhan等人发现的,像前列腺素一样,参与炎症的发生。例如,据报道,消退素E1对疼痛有效,并且RvE1诱导炎症终止,并且在治疗变应性炎症性疾病方面是有效的。此外,据报道,在哮喘患者和动脉粥样硬化患者中显示出积极促进慢性炎症性疾病的炎症终止的低水平因子,例如由阿司匹林诱导的脂氧素A4和脂氧素(lipixin)。
因此,尽管已经进行了各种尝试寻找用于诱导炎症终止并因此治疗与异常炎症终止相关的疾病的新物质(韩国未审查专利申请No.10-2015- 0011875),但是已知包含在脂氧素、消退素等中的化合物由于其结构中存在多个双键而代谢不稳定并因此在体内迅速降解,并且有些难以作为通过物质的大规模生产而开发的药物,因此在成药性方面存在很大问题。
同时,白三烯B4(LTB4)是通过介导急性和慢性炎症的5-脂氧合酶途径从花生四烯酸(AA)合成的一组炎性脂质介质。已知LTB4通过结合两种类型的受体BLT1和BLT2来发挥其生物学活性。作为G蛋白偶联受体 (GPCR)家族成员之一的白三烯B4受体2(BLT2)是对LTB4具有低亲和力的受体,并且是通过5-脂氧合酶依赖性途径诱导的花生四烯酸(AA)的脂质介质。
因此,为了解决上述的传统问题,本发明人鉴定了显示出BLT2 抑制活性的新颖化合物。另一方面,本发明人进行了开发诱导有效终止炎症的化合物的研究,并主要确定了包含上述化合物的炎症性疾病治疗剂。

本文使用的术语“治疗”是指通过施用根据本发明的药物组合物来减轻或有益地改变炎症性疾病的症状的所有行为。
在本发明中,炎症性疾病是由BLT2的过度表达引起的疾病,可以是选自哮喘、动脉粥样硬化、癌症、瘙痒症、类风湿性关节炎和炎症性肠病中的一种或多种,但是本发明不限于此。除了本说明书中提出的疾病以外,本领域已知的所有BLT2相关炎症性疾病都包括在炎症性疾病中,其可以用具有本发明式1结构的化合物预防或治疗。在特定的例子中,癌症可以是由作为肿瘤基因的BLT2或Ras的过表达引起的任何癌症。癌症可以是但不限于选自肾癌,前列腺癌,胰腺癌,乳腺癌,脑肿瘤,皮肤癌和肝癌。
在本发明中,G蛋白偶联受体(GPCR)家族的成员BLT2是对 LTB4具有低亲和力的受体,因此本发明的组合物抑制由BLT2引起的细胞生长以预防或治疗炎症性疾病。更具体地说,LTB4诱导的趋化运动性可以通过抑制由BLT2活性诱导的ROS的产生来抑制。
本文使用的术语“抑制”是指抑制基因转录、mRNA加工、翻译、易位和成熟中的某一步骤,或抑制蛋白质之间的结合,激活蛋白质或通过其传递信号。
除了活性成分之外,本发明的药物组合物还可以包含药学上可接受的载体。在本文中,药学上可接受的载体通常用于制剂中,并且包括但不限于乳糖,右旋糖,蔗糖,山梨糖醇,甘露醇,淀粉,阿拉伯胶,磷酸钙,藻酸盐,明胶,硅酸钙,微晶纤维素,聚乙烯吡咯烷酮,纤维素,水,糖浆,甲基纤维素,羟基苯甲酸甲酯,羟基苯甲酸丙酯,滑石,硬脂酸镁和矿物油。另外,除了所述组分之外,可以进一步包括润滑剂,润湿剂,甜味剂,调味剂,乳化剂,悬浮剂或防腐剂。
取决于期望的方法,本发明的药物组合物可以经口或肠胃外(例如静脉内,皮下,腹膜内或局部)施用,并且药物组合物的剂量可以根据患者的状况和体重,疾病的严重程度,药物类型,给药途径和时间而变化,并且可以由本领域普通技术人员适当地选择。
本发明的药物组合物以药物有效量施用。本文使用的“药学有效量”是指足以以适用于医学治疗的合理利益/风险比治疗疾病的量,并且有效剂量可以通过包括患者疾病类型,严重程度,药物活性,对药物的敏感性,给药时间,给药途径和排泄率,治疗的持续时间和同时使用的药物以及医学领域中众所周知的其它参数的参数来确定。本发明的药物组合物可以单独给药或与其他治疗剂组合给药,并可以与常规治疗剂顺序或同时给药,或者以单剂量或多剂量给药。考虑到所有上述参数,重要的是以最小剂量达到最大效果而没有副作用,并且这种剂量可以由本领域普通技术人员容易地确定。
具体而言,本发明的药物组合物的有效量可以取决于患者的年龄,性别,状况和体重,体内活性成分的吸收率,失活率,排泄率,疾病的种类或组合使用的药物,并且通常可以每天或每隔一天以每千克体重0.001 至150mg,优选0.01至100mg给药,或分成每日一次或三次给药。然而,有效量可以根据给药途径,肥胖症的严重程度,性别,体重或年龄而变化,因此,本发明的范围不受剂量的任何限制。

更具体地,将在实验实施例1中制备的各自1×104个的不 BLT2表达细胞(CHO-pcDNA3.1细胞)和BLT2表达细胞(CHO-BLT2细胞)分配到96mm培养皿并培养24小时。之后,除去培养基,加入无血清RPMI培养基,2小时后,用所述实施例之一中制备的每一种化合物(10μM)预处理细胞1小时,10μMDMSO(化合物溶剂)作为对照,并且10μM的1-[5-乙基-2- 羟基-4-[[6-甲基-6-(1H-四唑-5-基)庚基]氧基]苯基]-乙酮(LY255283;Cayman)作为阳性对照。随后,在LTB4(300nM)的处理后,将细胞培养24小时。每孔加入20μL MTT溶液(5mg/ml,Sigma-Aldrich),将细胞置于潮湿的CO2培养箱中在37℃培养4小时,然后除去上清液,将200μL DMSO加入到每个孔中以溶解不溶性紫色甲臜(formazan)晶体。使用酶标仪(Molecular Devices,Sunnyvale,CA)在550nm处测量吸光度,并重复测量三次。
结果,如图1A至1D 所示,当BLT2表达细胞(CHO-BLT2 细胞)用作为BLT2配体的LTB4(300nM)(DMSO+)处理时,与用乙醇(DMSO-) 处理的那些细胞相比,细胞生长增加20%至35%,并且当BLT2表达细胞 (CHO-BLT2细胞)用阳性对照LY255283预处理时,与用对照DMSO处理的那些细胞相比,表现出约90%的细胞生长,因此,证实了通过所述实施例化合物的处理,表现出对细胞生长的抑制作用。具体而言,确认了本发明化合物AC-1632(78.7%),AC-1635(71.6%),AC-1646(72.1%)和AC-1650(82.2%) 表现出生长抑制效果。

实验实施例3.确认通过BLT2抑制诱导癌细胞死亡的效果
本发明人已通过实验证实,根据抗癌剂抗性程度,BLT2表达成比例地增加,并且通过BLT2抑制,抗癌剂抗性显著降低。因此,在本发明化合物与抗癌剂顺氯氨铂联合治疗时,尽管所述抗癌剂的耐受性,意图确认在表现出抗癌剂耐受性的卵巢癌细胞(SKOV-3细胞)中是否诱导癌细胞的死亡。
使用3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑鎓溴化物(MTT) 方法检测癌细胞的死亡。更具体地说,将1×105个对所述抗癌剂有抗性的卵巢癌细胞(SKOV-3细胞)分配到12孔培养皿中,培养24小时。将0.5%血清 RPMI培养基用所述实施例之一中制备的每一种化合物(10μM)各预处理30 分钟,10μM DMSO(化合物溶剂)作为对照,10μM LY255283作为阳性对照。之后,用50μM的抗癌剂顺氯氨铂处理,然后将细胞培养24小时。每孔加入20μLMTT溶液(5mg/ml,Sigma-Aldrich),并将细胞在潮湿的CO2培养箱中于37℃培养4小时。之后,除去上清液,向各孔中加入500μL的 DMSO以溶解不溶性的紫色甲臜晶体。使用酶标仪(Molecular Devices, Sunnyvale,CA)在550nm处测量吸光度,并重复测量三次。
如图所示,如图2A-2C所示,在所述阳性对照LY255283 和顺氯氨铂共同处理时,与单独使用抗癌剂顺氯氨铂处理的情况相比,抗各种抗癌剂的卵巢癌细胞(SKOV-3细胞)的死亡增加。此外,当在顺氯氨铂存在下用AC-1070、AC-1072、AC-1073或AC-1074化合物处理细胞时,与用阳性对照LY255283共同处理时相比较,细胞死亡率高度增加。结果表明,本发明的化合物(AAC-1070,AC-1072,AC-1073和AC-1074)可降低抗癌剂抗性,从而通过抗癌剂顺氯氨铂以优异的效率诱导癌细胞死亡,因此可以用作提高抗癌效果的药物组分。

使用包括具有6.5mm直径的聚碳酸酯过滤器(8μm孔径, Corning Costar)的Transwell小室(Transwell chamber)分析趋化运动性。具体而言,在37℃下用在无血清的RPMI 1640培养基中的10μg/mL纤连蛋白涂布所述过滤器下表面1小时。通过以下操作进行实验:将所述过滤器干燥并用含有不同量的LTB4的RPMI 1640培养基包被在Transwell小室的下部孔中,并将稳定表达BLT1和BLT2的CHO细胞加载到含有无血清的RPMI 1640培养基的上部孔中,最终浓度为2×104个细胞/100μL。为了评估抑制剂的效果,在分配之前用每种抑制剂预处理细胞30分钟。将细胞在37℃,5% CO2下培养3小时后,将所述过滤器用甲醇固定3分钟,用苏木精和曙红染色10分钟。在该实验中,细胞是BLT2表达细胞(CHO-BLT2细胞)和BLT1 表达细胞(CHO-BLT1细胞),LY255283和U75302用作阳性对照,BLT2配体 LTB4(300nM)、BLT1配体LTB4(10nM)和溶血磷脂酸(LPA;100nM)用作比较对照。在光学显微镜下(放大倍数200倍)通过计数过滤器下侧的细胞来定量分析趋化运动性。对于每个分析,对6个区域进行计数,每个样品分析两次,并且该分析重复三次。
结果,在图3A至3D和下面的表1中所示,在BLT2表达细胞(CHO-BLT2细胞)中,随着本发明化合物(AC-1074)的浓度增加(10-4,10-3, 10-2,10-1,1,10和102),在无血清条件下CHO-BLT2细胞的趋化运动性受到抑制,并且AC-1074化合物的50%抑制浓度(IC50)为6.024μM。
[表1]
另外,如图4A所示,证实当用BLT2配体LTB4 (300nM)(DMSO+)处理BLT2表达细胞(CHO-BLT2细胞)时,与用乙醇 (DMSO-)处理的细胞相比,细胞趋化运动性增加2.9倍,以及当用10μM的作为阳性对照的LY255283预处理BLT2表达细胞(CHO-BLT2细胞)时,与用配体LTB4处理的那些细胞相比,趋化运动性为90%,并且当用10μM本发明化合物(AC-1074)预处理BLT2表达细胞时,与用配体LTB4(DMSO+)处理的那些细胞相比,趋化运动性被抑制53%。
另外,如图4B所示,证实当用BLT1配体LTB4 (10nM)(DMSO+)处理BLT1表达细胞(CHO-BLT1细胞)时,与用乙醇(DMSO-) 处理的那些细胞相比,趋化运动性增加2.8倍,以及当用10μM本发明化合物(AC-1074)预处理BLT2表达细胞时,与用配体LTB4(DMSO+)处理的那些细胞相比,趋化运动性没有变化。
另外,如图4C所示,证实了当用LPA(100nM)(DMSO+)处理BLT2表达细胞(CHO-BLT2细胞)时,与用乙醇(DMSO-)处理时相比,趋化运动性提高了3.4倍,以及当用10μM本发明化合物(AC-1074)预处理BLT2 表达细胞时,与用配体LPA(DMSO+)处理的那些细胞相比,趋化运动性没有变化。
结果显示,在BLT2稳定表达的细胞(CHO-BLT2细胞)中,趋化运动性通过LTB4刺激增加,本发明化合物(AC-1074)可能显著抑制趋化运动,并且因此可以用作抑制LTB4诱导的BLT2依赖性趋化运动的药物组分。
实验实施例5.确认抑制LTB4和BLT2结合的效果
使用放射性氚(H3)标记的LTB4([3H]LTB4,ARC;比活性 160.0Ci/mmol)分析LTB4和BLT2结合的抑制(配体结合亲和力)。将2×106个CHO-BLT2细胞接种到100-mm培养皿中并培养48小时后,实验方法如下进行:将收集的细胞用均化器共处理5次,每次1分钟,以分离细胞膜的蛋白质。之后,将细胞在4℃和45,000rpm下离心40分钟以仅收集细胞膜的蛋白质,由此定量蛋白质浓度为40μg/45μL。当用相同量的[3H]LTB4(5nM) 处理用以相同方式定量的含BLT2的细胞膜蛋白,接着用不同浓度(10-9,10-8, 10-7,10-6或10-5M)的化合物处理时,使用Hidex 300sL液体闪烁计数器测量抑制氚标记的LTB4和BLT2结合的抑制程度。
结果,如图5所示,证实了在BLT2表达细胞(CHO-BLT2 细胞)中,随着本发明化合物(AC-1074)的浓度增加(10-9,10-8,10-7,10-6和10-5),LTB4和BLT2的结合被抑制,AC-1074化合物的IC50为140.35nM。
实验实施例6.通过LBT2抑制确认抗哮喘作用
肥大细胞在对哮喘的初始反应中起关键作用,当过敏原通过气道从外部进入体内时,肥大细胞被激活,从而分泌各种细胞因子(白细胞介素-4和白细胞介素-13)。由于细胞因子,发生炎性细胞的流入,以及粘液的产生和气道收缩。本发明人使用由Orient(Seoungnam,Korea)提供的7周龄 (18-20g)雌性BALB/c小鼠进行实验以证实抗哮喘作用,并且在小鼠中诱导了哮喘。在第1天和第14天,腹膜内注射2.5mg的含有20mg卵清蛋白(OVA)的佐剂氢氧化铝凝胶(alum;Pierce,Rockford,IL)以使雌性C57BL/6小鼠敏化。在两次初始致敏之后,在第21天,第22天和第23天,使用超声波雾化器将1%OVA喷雾到小鼠体内。在喷雾1%OVA之前1小时腹腔内注射本发明化合物如AC-1074(5mg/kg),LY255283(5mg/kg,Cayman)或DMSO。最初致敏后,在第24天检测到AHR,并在第25天解剖小鼠以观察哮喘表型,例如炎性细胞因子IL-4的表达和炎性细胞(嗜中性粒细胞)的流入。此外,AHR 检测是在气道收缩剂乙酰甲胆碱(根据条件6.25至50mg/ml)施用于小鼠后进行的。气道收缩剂的施用通过使用超声波雾化器通过所述腔室的入口喷射3 分钟来进行。使用增加的间歇作为哮喘现象的指标来分析AHR。
结果,如图6所示,在哮喘诱导小鼠(OVA/DMSO)中,与未诱导哮喘的小鼠(正常)相比,AHR增加了约12倍,以及在小鼠预先用本发明化合物(AC-1074)10μM处理时,与施用50mg/ml所述气道收缩剂的小鼠相比,AHR降低了42%。
另外,如图7和8所示,证实当用10μM阳性对照 LY255283预处理时,在施用50mg/ml气道收缩剂的严重哮喘诱导的小鼠中,AHR降低69.2%,并且从小鼠腹腔分离的细胞中IL-4的产生减少了 67.2%。此外,证实了当用10μM本发明化合物(AC-1074)预处理时,在以50mg/ml施用所述气道收缩剂的严重哮喘诱导的小鼠中,AHR降低59%,以及从小鼠腹腔分离的细胞中IL-4的产生减少了35.5%。
结果表明,本发明化合物(AC-1074)可抑制哮喘动物模型中的AHR,并抑制炎性细胞因子IL-4的产生以减轻哮喘症状,因此可用作具有抗哮喘作用的药物成分。
