Description

一种芒果苷 -6-0-钙盐及其制备方法与用 ^ 技术领域
[0001] 本发明涉及一种芒果苷 -6-0-钙盐及其制备方法。
[0002] 也涉及芒果苷 -6-0-钙盐作为中间体在制备芒果苷 -6-0-小檗碱盐中的用途。
背景技术
[0003] 芒果苷 (mangiferin)是天然多酚类化合物, 分子式: C 19H 180„, 分子量: 422, 其化学结构如下:
Figure imgf000002_0001
[0004] 关于芒果苷钙盐, WO2009065287 Al、 WO2008061480 Al、 9 、 C N101919839的公幵内容包括: 1) 结构方面: 芒果苷钙盐的通式化合物 (a) 、 芒果苷 -3-0-钙盐 (b) 、 芒果苷 -3, 7-0-钙盐 (c) , 结构式如下:
Figure imgf000002_0002
[0006] 2) 用途方面: 作为胰岛素增敏剂、 ΑΜΡΚ激动剂、 过氧化物酶增殖物激活受 体激动剂的医药用途。
[0007] WO2010/145192A1披露一种芒果苷小檗碱盐, 根据 WO2010/145192A1说明书 第 5页-第 7页第 2段所披露的核磁数据分析获知, 其所披露的芒果苷小檗碱盐应为 芒果苷 -3-0-小檗碱盐与芒果苷 -7-0-小檗碱盐的组合物, 但关于芒果苷 -3-0-小檗 碱盐与芒果苷 -7-0-小檗碱盐的比例如何, WO2010/145192A1并未予以阐述。 技术问题
[0008] 按照药物注册的要求, 上市药物所提供的原料药结构必须是明确的, 如果原料 药是组合物, 其比例也必须是确定的, 才能符合药物质量可控的要求。 可见 W0 2010/145192A1所披露的芒果苷小檗碱盐若做为原料药, 还需解决进一步明确结 构的问题。 而分析芒果苷结构可知, 芒果苷分子结构中有 4个酚羟基, 所以芒果 苷成盐位点存在多种可能性, 这使得获得单一成盐位点的芒果苷盐的技术难度 大大增加。
[0009] 另外, WO2010/145192A1披露的芒果苷小檗碱盐的制备方法 【详见说明书第 4 页, 第 8-10页的实施例】 , 皆采用将芒果苷与碱性钠 (钾) 盐反应制备成芒果苷 单钠 (钾) 盐, 再将芒果苷单钠 (钾) 盐与小檗碱反应生成芒果苷小檗碱盐的 方法。 该方法存在以下问题:
[0010] 由于芒果苷原料是来源于植物的提取物, 可能因植物品种、 采集吋间或采集地 域的不同以及提取工艺的差异, 芒果苷原料中新芒果苷等芒果苷类似物以及鞣 质等杂质批次间的含量差异会较大; 在此情况下, WO2010/145192A1披露的芒 果苷小檗碱盐的制备方法, 采用芒果苷原料投料制成芒果苷单钠 (钾) 盐溶液 , 直接与盐酸小檗碱溶液反应制备芒果苷小檗碱盐, 极易出现芒果苷小檗碱盐 批次间质量一致性差异较大的问题; 同吋还会存在着芒果苷投料准确性的问题 。 若以芒果苷单钠 (钾) 盐固体物投料制备芒果苷小檗碱盐, 则需使用乙醇、 丙酮等结晶溶媒将其沉淀析出, 这样则会导致制备过程中较大量的乙醇、 丙酮 、 乙酸乙酯等有机溶剂的使用, 这些有机溶剂不仅成本高, 还会增加芒果苷小 檗碱盐的溶剂残留风险, 而且在工业生产中会带来沉重的环保压力。 如若采用 高纯度芒果苷 (含量≥98%) 作为原料也可以解决芒果苷小檗碱盐质量问题, 但 由于高纯度芒果苷制备工艺复杂, 会大大提高芒果苷小檗碱盐的生产成本。 问题的解决方案
技术解决方案 [0011] 为了解决芒果苷小檗碱盐做为原料药, 需明确结构的问题; 同吋也为了解决 W O2010/145192A1披露的芒果苷小檗碱盐的制备方法中存在的批次间质量一致性 差等问题, 发明人经过大量研究, 获得芒果苷 -6-0-钙盐这一新的单一成盐位点 的芒果苷钙盐, 并且研究出以芒果苷 -6-0-钙盐为中间体制备单一成盐位点的芒 果苷 -6-0-小檗碱盐的方法。 该技术方案解决了前文所述的以下问题:
[0012] 1、 采用芒果苷 -6-0-钙盐为中间体制备芒果苷 -6-0-小檗碱盐, 解决了芒果苷 小檗碱盐结构不明确的问题;
[0013] 2、 采用芒果苷 -6-0-钙盐为中间体制备芒果苷 -6-0-小檗碱盐, 解决了制备芒 果苷小檗碱盐批次间质量一致性差的问题。
