Definitions

  • the present invention relates to a novel use of chlorogenic acid, in particular to the use of chlorogenic acid for the preparation of a medicament for the treatment and/or prevention of liver damage.
  • Chlorogenic acid is a phenol that is isolated from the leaves and fruits of dicotyledonous plants (such as honeysuckle leaves, coffee beans, and hollyhocks) and is also a source of many Chinese herbal medicines (such as Eucommia ulmoides, Calendula, Yinchen, etc.).
  • the main active ingredients of antibacterial, anti-inflammatory, detoxification and detoxification of traditional Chinese medicine compound preparations have become one of the main indicators for quality control of Chinese herbal medicine preparations.
  • Chlorogenic acid is a phenylpropanoid compound produced by the plant by the shikimate pathway during aerobic respiration.
  • chlorogenic acid is widely distributed in plants, ranging from higher melon leaves to ferns, but there are not many plants with high content, mainly in Lonicera and Artemisia plants. Among them, including Eucommia, Honeysuckle, Sunflower, Coffee, Cocoa. Since chlorogenic acid is a polar organic acid, it is easily soluble in alcohol and water, and is insoluble in chloroform and ether. Therefore, there are many extraction methods for chlorogenic acid. Alcohol (methanol, ethanol) is dissolved and water is extracted. Shen, alcohol extraction lead, lime emulsion precipitation and polyamide column chromatography.
  • Hyaluronic acid is one of the enzymes that cleave mucopolysaccharide, which catalyzes the decomposition of hyaluronic acid (HA), which is related to the permeability and inflammatory response of the vascular system.
  • HA is a mucopolysaccharide composed of uronic acid and acetylglucosamine, which has various functions such as healing wounds, moisturizing the skin, lubricating joints and preventing inflammation.
  • chlorogenic acid From the ethyl acetate extract of Echinacea amgustifolia DC roots, 3,5-dicaffeoylquinic acid (carbamate) and chlorogenic acid have strong inhibitory effects on HAase activation. Studies in animals have shown that the use of chlorogenic acid can reduce the peak of hyperglycemia caused by the use of glucagon (decomposed by glycogen). Therefore, chlorogenic acid can lower blood sugar levels and increase the concentration of hepatic glucose-6-phosphate and hepatic glycogen. 2.
  • Chlorogenic acid inhibits lipoxygenase activity in prostaglandin metabolism, inhibits oxidation of vitamin A, protects adrenaline from oxidation, and resists retinoic acid 5 6-epoxidation bioactivity, methyl chlorogenic acid and dicaffeyl quinic acid inhibit mitochondria and [cleavage of lipid peroxidation].
  • Chlorogenic acid and 3,5-dicaffeoylquinic acid are small molecular compounds that react rapidly with peroxy radicals, so they are potentially important biological antioxidants. The possible antioxidant mechanisms are: The catechols partially accept hydrogen donors as peroxy radicals, which in turn are converted into low activity products. Therefore, they can terminate the chain radical reaction. 3, anti-cancer effect: Chlorogenic acid is an important substance in plant metabolism, but also an inhibitor of active tumors. Recently, Japanese scholars have studied the mutant inhibition of Eucommia tea.
  • Chlorogenic acid is a major phenolic compound in coffee. The daily intake of coffee is 0.5 - lg per day. Chlorogenic acid and caffeic acid are anti-ftulating agents in vitro and may therefore have an effect on the prevention of cardiovascular disease.
  • chlorogenic acid has antibacterial, antiviral, liver and gallbladder, anti-tumor, P blood pressure, blood lipids, free radical scavenging and other effects (chlorogenic acid and its extraction and purification and application prospects, grain and oil, 2003 Phase 9, page 44), can also significantly increase gastrointestinal motility and promote gastric secretion, widely present in many plants.
  • liver-protecting effect of chlorogenic acid is the concept of the theory of treatment of traditional Chinese medicine theory, is a generalization of the treatment of diseases, and the concept of the five internal organs of Chinese medicine is different from the concept of the organs of Western medicine.
  • the five internal organs of Chinese medicine do not specify an organ. Therefore, the "liver” that Chinese medicine theory thinks does not refer to the specific organ "liver,”.
  • Liver injury is a general indicator of specific organ lesions, including liver dysfunction; liver dysfunction is a decompensated liver injury, an irreversible liver injury characterized by obvious clinical symptoms and abnormal laboratory parameters. Therefore, whether a drug having a hepatoprotective effect against liver damage or liver dysfunction is not apparent to those skilled in the art.

Description

绿原酸在制备治疗和 /或预防肝损伤的药物中的用途 技术领域
本发明涉及绿原酸的新用途 , 具体来说是綠原酸在制备具有治疗和 /或预 防肝损伤的药物中的用途。 背景技术
绿原酸(chlorogenic acid )是一种从双子叶植物(如忍冬叶、 咖啡豆、 向 曰葵)的叶和果实分离得到的酚类,也是许多中草药 (如杜仲、 金艮花、 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_0001
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, 从高等默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(甲醇、 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-碑酸 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 基葡萄糖組成的一种粘多糖, 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质过氧化作 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 腎上腺素免受氧化, 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 [啟粒体脂质过氧化。 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。 日常饮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 ft化剂,因此可能对预防心血管疾病有作用。 5、 绿原酸具有抗菌、 抗病毒、 保肝利胆、 抗肿瘤、 P争血压、 降血脂、 清除自 由基等作用 (绿原酸及其提取纯化和应用前景, 粮食与油脂, 2003年第 9期, 第 44页), 还能显著增加胃肠蠕动和促进胃液分泌, 广泛存在于许多植物中。
虽然有文献报道绿原酸的保肝作用, 但 "保肝,,是中医理论对治疗法则的 概念,是一种针对治疗疾病广义的概括,且中医五脏的概念不同于西医的脏器 的概念, 中医的五脏并不具体指定某一个脏器, 因此, 中医理论认为的 "肝" 并非是指具体的脏器 "肝,,。 肝损伤是针对具体脏器的病变的泛指, 它包括肝 功能不全; 肝功能不全是失代偿的肝损伤, 是不可逆的肝损伤, 其特征是有明 显临床症状和实验室指标异常。 因此,具有保肝作用的药物是否针对肝损伤或 肝功能不全, 对本领域技术人员来说, 并非可以显而易见地推知的。 目前, 尚未见绿原酸预防和 /或治疗肝损伤的相关报道。 发明内容
本发明的目的是提供绿原酸在制备治疗和 /或预防肝损伤的药物的用途。 本发明提供了綠原酸在制备治疗和 /或预防肝损伤的药物的用途。 进一步 地, 所述的药物是治疗肝功能不全的药物。 更进一步地, 所述的药物是治疗和 /或预防严重的肝损伤至肝功能不全的药物。 更进一步地, 所述的肝功能不全 是由反复肝损伤导致的肝功能不全。
所述的肝损伤是上位概念,肝功能不全 (hepatic insufficiency)是相对下位概 念。在某些方面两者属并列的适应症。二者都有肝脏形态结构的破坏和肝功能 的异常, 前者是比较轻度的损害, 通过肝脏的代偿功能, 一般不会发生明显的 功能异常。后者是损害比较严重而且失去代偿功能, 引起明显的肝功能异常改 变。
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, 所述的药物是治疗和 /或预防中毒性肝损伤的药物。 其中, 所述的 中毒性肝损伤是工业毒物中毒性肝损伤,农药类中毒性肝损伤、 药物中毒性肝 损伤或植物类中毒性肝损伤。
所述的药物是治疗和 /或预防病毒感染所致肝损伤的药物。 进一步地, 所 述的药物是治疗曱型、 乙型、 丙型肝炎病毒引起的肝损伤的药物。
所述的药物是治疗和 /或预防寄生虫感染所致肝损伤的药物。
所述的药物是治疗和 /或预防梗阻性化脓性胆管炎、 胆嚢胆管肝炎、 肝脓 肿或肝结核所致的肝损伤的药物。
所述的药物是治疗和 /或预防代谢障碍性肝肿大所致的肝损伤的药物。 本发明提供了一种治疗和 /或预防肝损伤的药物组合物, 它是由有效量的 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。 所述的药剂是口服制剂、 或注射制剂。
通过药效试验证明, 绿原酸具有治疗和 /或预防肝损伤的作用, 由于绿原 酸多来源于天然植物, 毒性极低, 且对机体整体机能有改善, 为临床提供了新 的用药选择。
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

本发明不仅提供了绿原酸在制备治疗和 /或预防肝损伤的药物中的新用 途,还提供了以绿原酸为活性成分的药物制剂。由于绿原酸多来源于天然植物, 成本低廉, 毒性极低, 且可以改善机体的整体机能, 因此, 以绿原酸为活性成 分的制剂特别适于肝损伤这类需要长期治疗用药的疾病,或者护肝保健等,其 价廉、 安全、 疗效显著为临床提供了新的用药选择。
