Description
技术领域
本发明涉及作为活性药物成分用于治疗一种或多种血液学疾患的式(I)的琥珀酸及一种或多种其衍生物、其药学上可接受的盐、多晶型物、溶剂化物、水合物、共晶、异构体及其溶剂化物。本发明进一步涉及用于治疗选自登革热、特发性血小板减少性紫癜(ITP)、贫血和化疗诱导的骨髓抑制的疾患的式(I)的化合物。本发明还涉及琥珀酸用于治疗一种或多种血液学疾患的用途,其中琥珀酸是从番木瓜叶中提取的。本发明还提供了包括式I的琥珀酸及一种或多种其衍生物的药物组合物,以及治疗一种或多种血液学疾患的方法。
背景技术
背景描述包括可用于理解本发明的信息。它不是承认,本文提供的任何信息是现有技术或与目前要求保护的发明有关,或明确或隐含引用的任何出版物均为现有技术。
琥珀酸是一种四碳二羧酸,它采取阴离子琥珀酸根的形式,其作为代谢中间体具有多种生物作用。柠檬酸循环的中间体阴离子琥珀酸根和琥珀酸具有广泛的工业应用。琥珀酸通常用作食品和饮料的调味剂。它被广泛用作染料、香料、漆、摄影化学品、醇酸树脂、增塑剂、金属处理化学品和涂料的中间体。它被用作许多商业上重要的化学品(包括1,4-丁二醇、乳酸和1,3-丙二醇)的前体,并用作聚合物合成的单体。
琥珀酸还用于制造药,诸如镇静剂、抗痉挛药(antispasmer)、抗痰剂(antiplegm)、消炎药、anrhoers和避孕药。据报道,琥珀酸或琥珀酸根可用于与绝经有关的症状,诸如潮热和易激惹。琥珀酸根也被施加到关节炎和关节痛的皮肤。最近还报道了琥珀酸根对缺血/再灌注损伤具有心保护作用(SurgeryToday,vol.28,no.5,pages 522–528(1998))。一些其他应用包括如WO200059499中公开的抑制蛋白质酪氨酸磷酸酶活性和治疗由功能失调性信号转导引起的疾病状态的方法,所述方法包括单独或与蛋白质酪氨酸激酶活化剂(优选胰岛素)组合给药琥珀酸或其药学上可接受的盐。琥珀酸或琥珀酸根参与身体中的几种化学过程,并因此通常用于许多补充物中。
然而,琥珀酸或一种或多种其衍生物似乎未被作为药物成分充分利用。此外,琥珀酸是可广泛获得的并且以大规模合成地生产供人类使用,或者由生物质通过发酵来转化。另外,琥珀酸通常被认为是非常安全和有效的,并且通常具有非常好的耐受性。
因此,如此可普遍获得并且仍具有良好耐受性的琥珀酸或一种或多种其衍生物似乎未被作为活性药物成分开发。因此,需要在组合物、制剂中以及在用于治疗各种疾病的药剂或营养补充物的制造中进一步探索作为活性药物成分的琥珀酸及一种或多种其衍生物。
发明目的
本发明的目的是提供作为活性药物成分用于治疗一种或多种血液学疾患的琥珀酸或一种或多种其衍生物。
本发明的又另一个目的是提供用于制造用于治疗一种或多种血液学疾患的药剂或营养补充物的琥珀酸或一种或多种其衍生物。
本发明的另一个目的是提供用于制造用于治疗选自登革热、特发性血小板减少性紫癜(ITP)、贫血和化疗诱导的骨髓抑制的疾患的药剂的琥珀酸或一种或多种其衍生物。
本发明的另一个目的是提供从番木瓜叶提取的琥珀酸及其提取方法。

实施例1:从番木瓜叶制备冷冻干燥的提取物
将从印度马哈拉施特拉邦(Maharashtra)的潘奇加尼(Panchgani)获得的新鲜收获的番木瓜叶在去除主茎后剁碎成块。将叶在水中彻底洗涤,接着是在混合研磨机中研磨以制成水性悬浮液。将悬浮液通过平纹细布过滤,接着是进行高速离心(15,000x g,持续30分钟)以去除任何碎片。使水性提取物经受氯仿处理(1:1v/v,3X)以分离叶绿素和其他有机组分。通过旋转蒸发从水性部分中去除痕量的氯仿。然后通过用100%冰冷的乙醇处理水性部分使其经受乙醇沉淀以沉淀蛋白质和核酸。通过旋转蒸发进一步去除痕量乙醇,接着是在冷冻干燥器中冷冻干燥水性部分。将干燥的材料称重并储存在4℃下(图1)。5kg干燥的番木瓜叶产生100gm冷冻干燥的提取物。将冷冻干燥的提取物用于检查细胞系中的生物活性,并然后使用不同的HPLC技术进一步加工以纯化活性成分,这产生5mg纯化的化合物。
实施例2:使用具有不同HPLC级分的冷冻干燥的提取物在TF1细胞系中进行体外生物测定
源自患有红白血病的患者的TF-1细胞系(ATCC-CRL 2003)示出对GMCSF或IL-3的完全生长依赖性。对于本研究,TF-1细胞用于测量冷冻干燥的提取物、不同HPLC级分、纯化的化合物和琥珀酸衍生物中的体外活性。将细胞生长并保持在补充有2ng/ml rhGMCSF的RPMI-1640完全培养基。对于增殖测定,将TF-1细胞以10,000个细胞/孔铺板在96孔板中。在通过重复洗涤从细胞中去除rhGMCSF后,将细胞在包含5%FBS的RPMI 1640中培养过夜。然后将细胞用冷冻干燥的提取物、不同的HPLC级分、纯化的化合物和琥珀酸衍生物处理48h。用rhGMCSF(2ng/ml)处理的细胞用作阳性对照,而没有任何生长因子的细胞用作阴性对照。使用阿尔玛蓝(alamar Blue)细胞生存力试剂测量细胞增殖。在530nm的激发波长和590nm的发射波长下读取96孔板。获得的相对荧光单位与活细胞数目成正比。
使用制备型HPLC将来自实施例1的冷冻干燥的提取物进行级分分离。与冷冻干燥的提取物一起收集的不同级分直接用于TF-1细胞中以检查增殖潜能。rhGM-CSF用作阳性对照,而没有任何生长因子的细胞用作阴性对照。将从不同级分获得的值相对于细胞对照值归一化。由不同级分刺激的细胞增殖示出泊松分布模式。结果指示在级分7至级分21中存在生物活性化合物。(图2)
实施例3:从冷冻干燥的提取物中纯化活性化合物并使用该活性化合物进行生物测定
将冷冻干燥的提取物在流动相A(在水中0.1%的乙酸)中重构,并加载到50×250mm制备型-HPLC C18柱上。加载后,将柱用流动相A洗涤3倍柱体积,接着是用流动相B(100%乙腈,包含0.1%乙酸)洗脱。将实施例2的活性级分合并、干燥并经由分析型HPLC和UPLC技术经受进一步纯化以获得活性化合物。将最终的活性化合物干燥并使用不同的稀释度测试在TF-1细胞中的活性。用纯化合物观察剂量依赖性增殖(图3)。
实施例4:活性级分的表征
对于结构鉴定,通过熔点、1H-NMR、13C-NMR和LC-MS分析活性化合物。
来自番木瓜提取物的纯化合物熔点为184-186℃,其与商业琥珀酸的熔点相同。
通过1H NMR分析活性化合物。基于分析,纯化合物示出与琥珀酸的结构相似性(图4)。
通过13C NMR分析纯化合物。基于分析,纯化合物示出与琥珀酸的结构相似性(图5)。
使纯级分以负模式经受LC-MS分析。MS分析揭示了118道尔顿的主峰(m/z:117,以负模式)。类似地,商业琥珀酸也示出与纯化合物相似的LC-MS分布(图6)。
向来自番木瓜提取物的活性化合物的1H NMR加标商业琥珀酸。峰彼此重叠,这证实了从番木瓜叶提取的活性化合物为琥珀酸(图7)。
因此,从番木瓜叶中分离的活性化合物被确认为琥珀酸。
实施例5:用商业琥珀酸钠的生物测定
为了进一步验证NMR和LC-MS数据,获得了琥珀酸钠并将其用于测试琥珀酸根的增殖潜能。我们可以在TF-1细胞中重现与由从番木瓜叶提取物中分离的活性化合物(图3)示出的那样类似的为剂量依赖性方式的增殖活性(图8)。
实施例6:用琥珀酸的不同盐的生物测定
获得琥珀酸的Na、Mg和Ca盐,并将其用于测试不同的琥珀酸盐的增殖潜能。所有测试的盐形式在TF-1细胞中均示出增殖活性(图9)。
实施例7:琥珀酸根在细胞培养模型中诱导细胞增殖
人二倍体原代成纤维细胞WI38细胞被用于通过血清缺乏诱导静止。简而言之,WI38细胞在包含0.1%胎牛血清(FBS)的培养基中生长48hr,以引起可逆的细胞周期停止或静止或G0。为了了解琥珀酸根的作用,通过在存在琥珀酸根的情况下在缺乏丝裂原的培养基(0.1%胎牛血清)中孵育48h来诱导异步生长的人二倍体成纤维细胞(图10A)进入静止状态。在琥珀酸根的存在下,即使培养基中不存在丝裂原,WI38细胞也进入细胞周期(图10C)。在缺乏丝裂原的培养基的存在下生长的对照组示出了细胞周期停止或静止(图10B)。这表明琥珀酸根诱导细胞从静止期进入细胞分裂的作用。这里要提到的是,造血干细胞(HSC)大部分时间都是静止的,并且取决于外部或内部诱因经受有限数目的自我更新分裂,维持多能性。
实施例8:使用琥珀酸进行动物研究
使用纯琥珀酸(来自商业来源)在大鼠中进行了初步研究。每组(对照和治疗)使用六只动物。治疗组接受经口每天两次,剂量为100mg/kg琥珀酸,而对照组接受每天两次与处理组相同体积的水。CBC(全血细胞计数)是从单个大鼠抽取的血液中进行的。经口每天两次以100mg/kg琥珀酸给药大鼠7天可大幅度增加血小板计数(图11)。
实施例9:TF-1细胞中基因表达变化的RNA-seq分析
对于RNA-seq分析,用阳性对照GMCSF(GM)或琥珀酸根(E01)治疗TF-1细胞。未治疗的TF-1细胞(CC)用作对照以确定基础基因表达。三组全部一式三份进行RNA-seq。将E01或GM组的基因表达相对于CC的表达归一化。鉴定了与琥珀酸根治疗的细胞中的血小板分化途径相关的几种基因(例如,GP6、ANGPT1、ARRB、CD36、PECAM1等)。
实施例10:琥珀酸的一种或多种衍生物的生物活性的评估。
如实施例2所述,从商业来源获得2,2-二氟丁二酸并对其进行生物测定测试。与琥珀酸的钠盐相比,该衍生物示出了相似的活性。
