Description

含有亚铁氨基酸螯合物的组合物用于制造降低乳酸的药物的用途 技术领域
本发明涉及一种含有亚铁氨基酸螯合物的组合物的用途,特别是一种用于制造降低乳酸的药物的用途。
背景技术
糖类是运动中主要使用的能量来源,而糖类产生能量的方式分为有氧及无氧。糖类在无氧状况下分解,除了会产生能量外还产生乳酸,而乳酸的产生过程是由丙酮酸经乳酸脱氢酶转换而来。在运动强度较低时,糖类主要使用有氧方式产生能量,无氧参与较少。因此乳酸产生的速度不高,人体可以轻易代谢掉乳酸而不会累积在身体及血液中。当运动强度较强时,糖类采取无氧分解产生能量的比率提高,乳酸产生的速度也因此加快。一旦人体清除乳酸的速度赶不上乳酸产生的速度时,乳酸就会开始在身体中堆积。
因过量运动所引起的疲劳称作运动疲劳(exercise fatigue)。当氧与养分持续消耗以及乳酸持续累积时,肌肉会因收缩机能下降而变得僵硬,且肌肉纤维可能会因剧烈收缩而产生撕裂,从而造成肌肉酸痛、肌肉无力等不适症状。现有技术中常作为用于治疗运动疲劳的药物通常伴随不同程度的副作用,例如,肌肉松弛剂可能导致腹泻、口干、嗜睡等副作用;非类固醇消炎药则可能导致消化道黏膜损伤、肝功能异常、头晕、头痛、嗜睡等副作用。而中国台湾专利公开案第201406381号公开一种抗运动疲劳的药物组合物,该药物组合物为芸香素(rutin)可有效降低血液中乳酸量,用于治疗运动疲劳所引起的相关症状。然而芸香素可能会产生的副作用为过敏、喉头或胸口紧闷、呼吸障碍等。
因此,如何发展出一种可用于抗运动疲劳、具有较低副作用的药物且能有效降低乳酸堆积量,以有效预防及治疗运动疲劳所引起的相关症状,现有技术有待改善。

具体实施方式
以下配合附图及本发明的优选的实施例,进一步阐述本发明为达成预定发明目的所采取的技术手段。
制备例1  制备含有亚铁氨基酸螯合物的组合物
本实施例为用于制备含有亚铁氨基酸螯合物的组合物,其以下述方式制备。首先,将硫酸亚铁与甘氨酸(纯度98%以上)以重量比1:1.3混合并历经60℃至90℃加热8小时至48小时,以获得该含有亚铁氨基酸螯合物的组合物,其中亚铁氨基酸螯合物的亚铁与氨基酸螯合比例为介于1:1至1:4之间;再将所获得的含有亚铁氨基酸螯合物的组合物调制成浓度为每毫升含有5微克(即5μg/ml)、10μg/mL、25μg/mL、30μg/mL、50μg/mL、100μg/mL、250μg/mL、500μg/mL以及1000μg/mL,并以X代称该组合物。
制备例2  肺癌细胞培养
将非小细胞肺癌细胞株A549及H460以含有10%胎牛血清(fetal bovine serum,FBS)、1%青霉素[100单位/毫升(U/mL)]-链霉素[100微克/毫升(μg/mL)](penicillin-streptomycin)以及1%麸酰胺酸(glutamine)[200毫摩尔每升(mM)]的杜氏改良英格尔培养基(Dulbecco's Modified Eagle's medium,DMEM)培养于37℃、5%二氧化碳的培养箱中,待细胞贴附7至8分满时,再进行继代培养。
制备例3  乳癌细胞培养
将乳腺癌细胞株MDA-MB-231以含有10%胎牛血清、1%青霉素(100U/mL)-链霉素(100μg/mL)以及1%麸酰胺酸(200mM)的DMEM培养于37℃、5%二氧化碳的培养箱中,待细胞贴附7至8分满时,再进行继代培养。
制备例4  脑癌细胞培养
将脑神经胶质瘤细胞株U87-MG以含有10%胎牛血清、1%非必需氨基酸(non-essential amino acid,NEAA)以及1%青霉素(100U/mL)-链霉素(100μg/mL)的拉赛尔培养基(Roswell Park Memorial Institute, RPMI)培养于37℃、5%二氧化碳的培养箱中,约3天至4天继代培养一次。
实施例1  癌细胞经组合物X处理后乳酸分泌表现量
将制备例2至4培养的癌细胞(肺癌、乳癌及脑癌)以每孔3×104个细胞种入细胞孔盘,随后以制备例1所制得组合物X的浓度为30μg/mL、100μg/mL、250μg/mL、500μg/mL,或未添加组合物X作为控制组分别处理三种癌细胞。经24小时后,收取细胞上清液并以L-乳酸分析套组(L-lactate assay kit,购自于
Figure PCTCN2016083400-appb-000001
型号ab65331)测量癌细胞分泌至细胞培养液中的乳酸堆积量。
如图1所示,当施予组合物X浓度为30μg/mL于非小细胞肺癌细胞株A549的组别中,其乳酸堆积量相较于控制组降低了约20%;随着组合物X浓度增加,当施予组合物X浓度为500μg/mL的组别中,其乳酸堆积量降低了近50%。如图2所示,当施予组合物X浓度为100μg/mL于非小细胞肺癌细胞株H460的组别中,其乳酸堆积量相较于控制组降低了约20%;随着组合物X浓度增加到250μg/mL至1000μg/mL,其乳酸堆积量均降低至约30%。如图3所示,当施予组合物X浓度为5μg/mL于乳腺癌细胞MDA-MB-231的组别中,其乳酸堆积量相较于控制组降低了约10%;随着组合物X浓度增加到10μg/mL至100μg/mL,其乳酸堆积量降低约为40%至50%。如图4所示,当施予组合物X浓度为500μg/mL至1000μg/mL于脑神经胶质瘤细胞U87-MG的组别中,其乳酸堆积量相较于控制组降低了大于20%。
实施例2  肺癌细胞在正常或低氧下经组合物X处理后HIF-1α的表现量
将制备例2培养的非小细胞肺癌细胞A549以每孔3×104个细胞种入细胞孔盘,在正常供氧情下以制备例1所制得组合物X的浓度为100μg/mL或250μg/mL,或未添加组合物X作为控制组分别处理非小细胞肺癌细胞A549,经24小时后进行西方墨点法,分析HIF-1α的蛋白质表现量。另外,以CoCl2诱发低氧情况下,非小细胞肺癌细胞A549先以200μM CoCl2作用3小时,再以组合物X的浓度为100μg/mL或 250μg/mL作用24小时后,进行西方墨点法,以β-actin为基准进行定量分析HIF-1α的蛋白质表现量。
如图5所示,在正常供氧情形下施予组合物X的浓度为100μg/mL或250μg/mL于非小细胞肺癌细胞A549的组别中,HIF-1α的蛋白质表现量相较于控制组均显著下降,且降幅大于20%;在低氧情形下,未施予组合物X组别的HIF-1α的蛋白质表现量相较于控制组显著上升,然而施予组合物X的浓度为100μg/mL的组别其HIF-1α的蛋白质表现量相较于未施予组合物X组别有下降趋势,而当施予组合物X的浓度为250μg/mL的组别其HIF-1α的蛋白质表现量相较于未施予组合物X组别有显著降低,甚至可达到与正常情形下施予组合物X的浓度为100μg/mL或250μg/mL相近的HIF-1α的蛋白质表现量。因此,对于非小细胞肺癌细胞A549来说,本发明所述的组合物不论是在正常情况或低氧情况下都能减少HIF-1α的产生。
实施例3  组合物X抑制脑神经胶质瘤细胞葡萄糖摄取
将制备例4培养的脑神经胶质瘤细胞U87-MG以每孔3×104个细胞种入细胞孔盘,加入制备例1所制备的组合物X分别为0μg/mL(控制组)、100μg/mL(先以200μM CoCl2作用3小时模拟低氧)、30μg/mL、100μg/mL作用24小时,利用克雷布斯林格缓冲液(Krebs-Ringer buffer,KRB)进行饥饿流程(starvation)30分钟后,加入含有标记放射线元素3H的葡萄糖作用3小时,接着以PBS清洗3次,利用分解液(lysis buffer)收下细胞并放入闪烁液中,最后放入计数仪器(b-counter)中测量。
如图6所示,在低氧情形下施予组合物X浓度为100μg/mL于脑神经胶质瘤细胞的组别中,其葡萄糖摄取量相较于控制组并无显著差异;在正常供氧的情形下,施予组合物X的浓度为30μg/mL于脑神经胶质瘤细胞的组别中,其葡萄糖摄取量相较于控制组有下降的趋势;当施予组合物X的浓度为100μg/mL时,葡萄糖摄取相较于控制组有显著下降超过20%。
实施例4  组合物X对实验动物活动力的影响
针对美国癌症研究所(institute of cancer research,ICR)小鼠(每只约 重25克)分别以制备例1所制备的组合物X每日每只分别喂食0μg(控制组)、200μg以及900μg,每组各至少7只小鼠进行实验。持续喂食两周后,进行强迫游泳实验(forced swimming test)。
如图7所示,每天喂食200μg或900μg组合物X的小鼠相较于控制组而言,其平均游泳时间都有增加的趋势,且与喂食量有正相关增加的趋势。
实施例5  组合物X对实验动物血清中乳酸堆积的影响
针对ICR小鼠分别以制备例1所制备的组合物X每日每只分别喂食0μg(控制组)、200μg以及900μg,每组各至少7只小鼠进行实验。持续喂食两周后,进行强迫游泳实验后抽血检验血清中乳酸与乳酸脱氢酶含量。
如图8所示,每天喂食200μg组合物X的小鼠相较于控制组而言,其血清中乳酸含量有减少的趋势;每天喂食900μg组合物X的小鼠相较于控制组而言,其血清中乳酸含量则有显著降低。如图9所示,每天喂食200μg组合物X的小鼠相较于控制组而言,其血清中乳酸脱氢酶含量有增加的趋势;每天喂食900μg组合物X的小鼠相较于控制组而言,其血清中乳酸脱氢酶含量则有显著增加。
以上所述仅是本发明的优选的实施例而已,并非对本发明做任何形式上的限制,虽然本发明已以优选的实施例公开如上,然而并非用以限定本发明,任何熟悉本专业的技术人员,在不脱离本发明技术方案的范围内,当可利用上述公开的技术内容作出些许改动或修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案的内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本发明技术方案的范围内。
