绿原酸在制备具有增加骨髓细胞功效的药物中的用途 技术领域
本发明涉及绿原酸的新用途, 具体来说, 是绿原酸在制备具有增加骨髓细 胞功效的药物中的用途。
Figure imgf000002_0001
绿原酸广泛存在于各种药用植物如金银花等中,目前对它的化学结构研究 已经清楚, 已有人对其进行药用研究,报道了绿原酸可以应用于治疗肿瘤等疾 病。
绿原酸(chlorogenic acid )是一种从双子叶植物(如忍冬叶、 咖啡豆、 向 日葵)的叶和果实分离得到的酚类, 也是许多中草药(如杜仲、金银花、 茵陈 等)及中药复方制剂抗菌消炎、 清热解毒的主要活性成分, 目前已成为中草药 制剂质量控制的主要指标之一。绿原酸是植物体在有氧呼吸过程中经莽草酸途 径产生的一种苯丙素类化合物。 它是一种由咖啡酸 (caffeic acid)与奎尼酸 (鸡纳 酸, quinic acid, 即 1-羟基六氢没食子酸)缩合而成的缩酚酸, 异名咖啡鞣酸, 化学名 3-0-咖啡酰奎尼酸 (3-O-caffeoylquinic acid), 分子式为 C16H1809, 分子 量: 345.30, 半水合物为针状晶体, 时变为无水化合物, 易溶于水、 乙醇、 丙 酮, 微溶于乙酸乙酯, 常温下呈淡黄色固体。 绿原酸的结构式如下:
Figure imgf000002_0002
植物中绿原酸的生物合成包括了一系列的酶促反应。 在酶的催化下, 葡萄 糖转化成莽草酸 (shikimic acid),后者再转化成苯丙氨酸,最后经合成酶作用得 绿原酸。 绿原酸在植物中分布广泛, 从高等双子叶植物到蕨类植物均有报道, 但含量较高的植物不多, 主要存在于忍冬科忍冬属 (Lonicera)、 菊科蒿属 (Artemisia)植物中, 其中包括杜仲、 金银花、 向日葵、 咖啡、 可可树。 由于绿 原酸是极性较强的有机酸, 易溶于醇、 水, 难溶于氯仿、 乙醚,因此绿原酸的 提取方法较多, 有醇(曱醇、 乙醇)溶法、 水提醇沉、 醇提铅沉、 石灰乳沉淀 法及聚酰胺柱层析法等。
现有文献报道的绿原酸的药理作用有: 1、 对透明质酸酶及葡萄糖 -6-麟酸 酶的抑制作用: 透明质酸梅 (HAase)是裂解粘多糖的酶之一, 可催化透明质酸 (HA)的分解, 关系到血管系统的通透性和炎症反应。 HA是由糖醛酸和乙酰氨 基葡萄糖组成的一种粘多糖, 具有多种功能, 如治愈创伤, 使皮肤润湿健康, 润滑关节和防止炎症等。 从狭叶紫锥花( Echinacea amgustifolia DC )根的乙酸 乙酯提取物中发现 3,5-二咖啡酰奎尼酸 (朝鲜蓟酸)和绿原酸有较强的抑制 HAase激活的作用。动物体内的研究证明,使用绿原酸可以降低由使用胰高血 糖素引起的(肝糖分解造成的)高血糖峰值。 因此,绿原酸可以降低血糖水平, 提高肝脏葡萄糖 -6-磷酸和肝糖原的浓度。 2、 自由基的清除及抗脂^过氧化作 用: 绿原酸抑制前列腺素代谢中脂氧化酶活性, 抑制维生素 A的氧化, 保护 肾上腺素免受氧化, 抗维生素 A酸 (retinoic acid)5,6-环氧化的生物活性, 绿原 酸甲酯和二咖啡酰奎尼酸可抑制线粒体和微粒体脂质过氧化。 绿原酸和 3,5- 二咖啡酰奎尼酸属于小分子化合物, 能与过氧自由基快速反应, 因此它们是潜 在重要的生物抗氧化剂。 其可能的抗氧化机制为: 儿茶酚类 (catechols)部分作 为过氧自由基接受氢原子供体,继而转化成低活性产物。 因此, 它们可终止链 自由基反应。 3、 抗癌变作用: 绿原酸是植物代谢中的一种重要物质, 也是促 佛波醇酯活性肿瘤的抑制剂。近来, 日本学者研究了杜仲茶的变异原性抑制作 用(Antimutagenicity)与杜仲叶所含的绿原酸、 京尼平甙、 京尼平甙酸等抗变异 原性成分有关, 揭示了杜仲茶对肿瘤的预防具有重要意义。 4、 预防心血管疾 病: 绿原酸是咖啡中一种主要的酚类化合物。 日常引用咖啡的人每日摄取量为 0.5— lg。 绿原酸和咖啡酸在体外是抗氧化剂, 因此可能对预防心血管疾病有 作用。 5、 抗菌、 抗病毒作用: 绿原酸和异绿原酸对多种致病菌和病毒有较强 的抑制和杀灭作用, 还有利胆、 降压、 消炎及显著增加胃肠蠕动和促进胃液分 泌等药理作用。
目前, 关于绿原酸的制药用途有相关报道, 如 CN200410022438.6, 发明 名称: 高纯度绿原酸制剂,该发明涉及高纯度绿原酸为原料制备成药学上可应 用于临床的各种剂型的药品。 采用含量 95 % -105 %的绿原酸制成含 lmg-3g的 各种注射液、 无菌粉针、 各种片剂、 胶嚢、 口服液、 滴眼液、 软膏、 各种緩控 释制剂。绿原酸作为一种有效的中药成分,是大约 170余种中成药的定性或者 定量指标。 公开的申请号为 CN02829404.1 , 发明名称: "能作为抗白血病药 物的草药分子"的专利申请中,该发明公开了从萎叶叶提取物中或从任何其它 来源分离到的化合物绿原酸在治疗急性和慢性髓细胞性白血病和淋巴细胞性 白血病中新的用途,还提供了含有绿原酸和可药用添加剂的用于治疗急性和慢 性髓细胞性白血病和淋巴细胞性白血病的药物组合物, 它包含有效量的、从萎 叶叶的任何植物部分或任何其它天然或合成来源分离到的绿原酸 (CA)和 /或 3-0-P-香豆酰奎尼酸 (PCQ),和可药用添加剂。白血病是骨髓的粒系统细胞异常 增生而致的一种恶性肿瘤,因此,说明绿原酸可以通过抑制白细胞的过度增生, 从而对急性和慢性粒细胞性白血病即通常意义上的血癌有治疗的作用。
有些疾病, 如: 血小板减少症、 贫血、 白细胞减少症等, 与骨髓细胞功能 低下有关。增强骨髓细胞功效实质是通过对骨髓干细胞的作用,治疗或纠正血 小板减少症、 贫血、 白细胞減少症。 而在现有技术中, 尚未发现绿原酸对骨髓 功效具有影响的相关报道。 发明内容
本发明的技术方案是提供绿原酸的新用途, 具体地, 是在制备具有增加骨 髓细胞功效药物的用途。
本发明提供了绿原酸 Chlorogenic acid在制备增加骨髓细胞功效的药物中 的用途。
本发明采用的绿原酸可以是来自于天然植物提取、精制,也可采用合成方 式合成。
其中, 所述的药物是促进骨髓细胞增殖、 分化、 成熟与释放功能的药物。 进一步地,所述的药物是用于增加骨髓干细胞的药物。增加骨髓细胞功效实质 是指通过对骨髓干细胞的作用, 增加骨髓三大系统细胞的数量的作用。
进一步地, 所述的药物是用于增加骨髓造血干细胞的药物。
进一步地,上述用于增加骨髓造血干细胞的药物是用于增强造血功能,用 于白细胞减少症的药物; 更进一步地, 所述药物是治疗粒细胞减少症的药物。
或者,上述用于增加骨髓造血干细胞的药物是用于治疗血小板减少症、贫 血的药物。更进一步地,所述的贫血是失血性贫血、溶血性贫血、 巨细胞贫血、 再生障碍性贫血。
由于绿原酸可对整个骨髓细胞有促进作用 ,骨髓纤维化致整个骨髓三大系 统(红系、 粒系、 巨细胞系)的细胞减少, 出现红系的贫血, 粒系的白细胞减 少, 巨细胞系的血小板减少。
绿原酸对白细胞有正常增生作用, 是通过对正常的骨髓干细胞的促进作 用, 从而促进三大系统的骨髓细胞正常发生, 因为属于正常促进作用, 不会对 粒系统产生增生过度的作用。
贫血系各种原因致骨髓红系统增生障碍,使外周血红细胞数量和或红细胞 血红蛋白含量减少,或各种原因致外周血的红细胞破坏丟失过多,使外周血红 细胞数量和或红细胞血红蛋白含量减少而产生的疾病、 也是一种临床症状。
其中, 所述的药物是治疗骨髓纤维化的药物。
其中,所述的药物是治疗骨髓感染的药物。骨髓感染后也造成骨髓三大系 统的细胞減少, 绿原酸的作用是对整个骨髓细胞有促进作用。
其中, 所述的药物是对脾脏造血干细胞损伤有保护、修复作用的药物。 进 一步地,所述的药物是治疗脾功能亢进的药物。脾功能亢进致三大系统的细胞 在脾脏破坏加速,使细胞在外周血的周期缩短,绿原酸对整个骨髓细胞有促进 作用, 加快产出。
本发明还提供了一种具有增加骨髓细胞功效的药物組合物, 它是以有效 量的绿原酸为活性成分,加上药学上可接受的辅料或辅助性成分制备而成的药 剂。
其中, 所述的药剂中每制剂单位含有绿原酸 l-3000mg。 根据绿原酸动物 安全性试验(长期毒性试验)结果(160mg/kg )推算人用安全剂量为不大于 90mg/kg, 若人体体重按 50kg计算, 人用剂量不超过 4500mg/日。
进一步地, 所述的药剂中每制剂单位含有绿原酸 l-3000mg。
其中, 所述的药剂是口服制剂或注射剂。
经过实验, 发现绿原酸可升高白细胞; 可刺激犬骨髓细胞增生, 包括对正 常的骨髓干细胞的增加作用,并且绿原酸对 6QCo— γ射线致小鼠脾脏造血干细 胞损伤有显著地保护作用, 从而促进三大系统的骨髓细胞正常发生。
机体的造血过程是一个活跃的细胞增殖、 分化、 成熟与释放的过程。 它是 由多潜能造血干细胞的自我更新维持其数量的恒定, 并由多潜能造血干细胞 到各系定向祖细胞,再进一步增殖、 分化、 释放到外周血循环。 药物可通过影 响造血干细胞、 祖细胞的增殖分化等多种环节影响造血过程。 因此,造血祖细 胞体外培养技术的建立为本发明药物的作用提供了手段和方法。
本发明通过药效试验,对 9 月龄小鼠为实验模型并以同月龄的小鼠为对照 说明了绿原酸对其造血功能的影响。 研究结果显示小鼠 CFU-S、 CFU-GM、 CFU-E和 BFU-E的增殖分化能力和外周血 WBC数明显低于同月龄的小鼠。 而绿原酸可使小鼠降低的 CFU-S数明显增加,说明绿原酸可刺激造血干细胞 的增殖,同时绿原酸可明显促进小鼠骨髓粒单系祖细胞,早期、 晚期红系祖细 胞的增殖分化, 并可使其外周血 WBC数升高,证明绿原酸可影响小鼠造血的 整个过程,可知原酸可能调节机体内造血调控系统。通过小鼠血清集落刺激活 力的测定结果说明绿原酸可通过促进小鼠机体产生集落刺激因子来增强其祖 细胞的增殖分化。组织学的研究结果则进一步证实了绿原酸能增强小鼠的造血 功能。
由此, 绿原酸可治疗各种原因引起的贫血, 且不仅仅限于失血性贫血、 溶 血性贫血,造血不良性贫血包括巨细胞性贫血、再生障碍性贫血和脾功能亢进, 对各种原因引起的白细胞减少状态、粒细胞减少症、粒细胞缺乏症有治疗作用, 对各种原因引起的巨核系统改变如特发性血小板减少性紫癜等有治疗作用;对 各种原因引起的骨髓纤维化, 骨髓感染有一定治疗作用。
基于上述发现,绿原酸可以单独或与其他具有已知功效的药物一起采用各 种制药技术制备成各种药用剂型如但不仅仅限于口服剂型、静脉给药剂型和外 用剂型。
以下通过实验对绿原酸所具有的上述功效加以证实。应该理解的是,本发 明的实验例是用于说明本发明而不是对本发明的限制。根据本发明的实质对本 发明进行的简单改进都属于本发明要求保护的范围。 发明的具体实施方式
以下通过具体的药效学试验证明本发明的有益效果。

1、 实验方法
骨髓细胞 (BMC)的制备 将 C57动物安乐死后, 酒精消毒, 无菌剥取一侧 股骨, 用 RPMI-1640液通过 6号针头反复冲洗骨髓腔数次,再将冲出的骨髓细 胞液通过 4号针头制备成单细胞悬液。
小鼠骨髓造血干细胞 (CFU-S)的测定 C57小鼠, 无菌制备 BMC 悬液,计 数有核细胞后配成每亳升 5 X 104个细胞, 给经 8.0Gy60Go照射后小鼠尾静脉 输注 0.2 ml 细胞悬液, 第 9天安乐死受体鼠,取脾用 Bouin液固定 24h后计数 表面结节数。
骨髓粒单系祖细胞 (CFU-GM) 的测定 将定量 (1 X 105 ) 的骨髓细胞悬 液加马血清与 RPMI- 1640培养液在 37°C水浴中保温 10~20min,加入 30g/L 琼脂后混匀,转入含有 0.2ml 鼠肺条件刺激液的琼脂培养 中,于 37°C,0.05% C02饱和湿度的培养箱中培养 5 ~ 7天, 置低倍镜下计数含 50个细胞以上的集 落 (CFU-GM)数。
骨髓早期、 晚期红系祖细胞 (BFU-E、 CFUE)的测定 将培养体系配成终 浓度为 10%骨髓细胞悬液 (5 x 104 ml),200g L马血清 ,100g/L小牛血清白蛋白, 1 X 10-5 mol L二巯基乙醇、 10%爆式集落促进活性 (BPA), 0.8%甲基纤维素及每 亳升 1 U EPO等充分混合后,加 10 μ ΐ至微孔塑料培养板中,置培养箱中培养 3 天,用联苯胺染色后在倒置显微镜下计数 8个以上染色阳性细胞集落计为红系 集落形成单位 (CFU-E),培养 8天计数含 50个以上联苯胺染色阳性细胞集落为 爆式红系集落形成单位 (BFU-E)。
小鼠外周血象的测定 小鼠尾静脉采血, Coulter血细胞计数仪计数。 小鼠骨髓组织学观察 安乐死小鼠取完整左侧股骨,入 Hellyps液固定, 石蜡包埋切片 , HE 染色, 光镜下观察组织学变化。
2、 实验结果
( 1 )绿原酸小鼠骨髓造血干细胞的影响
将 C57 小鼠随机分为 3 組: 1组为 C57对照組,2、 3 组为绿原酸 10, 20m g/kg/天 x 8 天,静脉注射。 另取同月龄 C57对照組,每天给予生理盐水。 9 天 安乐死各组小鼠, 制备 BMC悬液,按前述方法输注给受体鼠。 9天安乐死取脾 固定观察结果, 结果显示模型对照组 C57 小鼠 CFU-S数 9.583 ± 1.084 ( n = 12)。 与给予绿原酸后 C57 小鼠相比较 CFU-S数明显减少, 予绿原酸后 C57 小鼠 CFU-S数分别为 20.667 ± 2.103 和 23.250 ± 2.379结果提示绿原酸对 C57小鼠 骨髓造血干细胞的增殖分化有一定刺激作用。

结果表明 C57小鼠外周血象中,其 WBC数明显低于同月龄小鼠。 绿原酸

( 4 )绿原酸对小鼠血清 CSA的影响
将各组小鼠分别心脏采血,静止离心制备血清,以血清取代肺条件刺激液 (CSF-GM), 观察其对 CFU-GM增殖的影响, 以 CFU-GM 的产率代表 CSA。 结 果证明 C57 小鼠血清的 CFU-GM的产率 77.333士 6.706明显低于给予绿原酸后 C57 小鼠 CFU-GM 173.000 ± 14.283 和 201.833 ± 18.065 (n=12,P <0.01)。 而给 予绿原酸后 10, 20 mg/kg C57 小鼠的 CFU-GM明显增加 (CFU-GM分别为 173.000 ± 14.283 和 201.833 ± 18.065)与 C57組相比有显著差异,提示绿原酸 可明显增强 C57 小鼠体内的 CSA,促进 C57 小鼠骨髓造血祖细胞的增殖分化。

组织学研究结果显示小鼠骨髓腔内造血祖细胞丰富,各系细胞均可见到, 并且形态良好,增殖旺盛,血窦较多。 而同月龄 C57 小鼠骨髓腔内造血细胞明 显减少,增生不活跃,以中晚幼粒细胞为主,甚至局部缺少造血细胞,纤维结締 组织增生,血窦较少。给予绿原酸后的 C57小鼠与未用药 C57小鼠相比其骨髓腔 内造血细胞明显增多,增生活跃,血窦较多,但较 C57小鼠骨髓造血细胞及血 窦为少。 这一结果说明绿原酸可明显改善 C57小鼠骨髓造血功能。
以下通过具体实施例说明绿原酸在本发明的新用途下,可制备成药学上常 规的制剂, 但绿原酸的用量并不仅仅限于所述的实施例的范围内。
