吡咯并喹啉醌钠盐的晶型及其制备方法和用途 技术领域
本发明涉及吡咯并喹啉醌钠盐的新晶型以及所述新晶型的制备方法、以及它们在的医药、功能性食品及化妆品领域中的用途。
背景技术
吡咯并喹啉醌化学名称为4,5-二氢-4,5-二氧代-1H-吡咯并[2,3-f]喹啉-2,7,9-三羧酸，又名methaxatin；其具有如下结构式：
Figure PCTCN2016099013-appb-000001
吡咯并喹啉醌是从微生物中发现的小分子化合物，广泛分布于人体的各组织器官中，被称为第十四种维生素；并广泛应用于医药、功能性食品及化妆品领域。例如：吡咯并喹啉醌能全面提高人体免疫功能，在医药领域中可用于防治肝损伤、减少自由基对人体的伤害、调理各种神经系统疾病、促进氨基酸的吸收、促进合成生长因子、防治老年痴呆症、促进合成谷胱甘肽、具有极强的抗癌功能。此外，在食品领域中，吡咯并喹啉可作为具有抗衰老效果的保健食品；在化妆品领域中，它是具有抗过敏作用、有美肌效果的物质。
对于多晶型化合物而言，不同的晶型可以具有不同的物理和化学性质；包括熔点、化学稳定性、表观溶解度、溶解速率、光学和机械性质等，而这些物理化学性能直接决定了某种特定晶型在药品、功能性食品、化妆品等领域中的使用效果。比如：现有技术方法获得的吡咯并喹啉醌钠盐的结晶晶型不稳定、吸湿性大，在常温储存的温度范围内，湿度变化幅度大，固体状态不理想，不适于加工(过滤、干燥、压片)，从而对吡咯并喹啉醌钠盐的应用和储存不利。现有技术中对吡咯并喹啉醌钠盐的晶型进行了一些改进，如：在专利CN201080031945中，其克服了一些文献报道中的结晶性低、残留溶剂高等缺点，但是同样具有吸湿性；而CN201210452297.6中的晶型A虽然吸湿性有所改善，为65％-85％RH下的引湿性小于3％，优选小于0.6％，但还是无法满足对晶型吸湿性要求较高的制剂工艺的需求。
因此，尽管在现有技术(除上述列举的两篇文献外，还包括但不限于下述文献：日本特开2005-530786号公报、日本特开2011-246442号公报、日本特开2007-269769号公报、国际公开第2011/007633、日本特公平7-113024号公报、CN201280028888.9)中，已经披露了吡咯并喹啉醌的一些晶型，但仍有必要开发出性能优于已知晶型，且具有广阔应用前景的新晶型。与现有技术相比，本发明提供的晶型引湿性更低，在75％RH下的引湿性小于0.3％，优选无引湿性。
本发明旨在提供一种结晶度高、产品纯度高，残留溶剂低，易于过滤、干燥、储存的晶型和环保无污染的工艺。

吸湿性试验。测试条件：将表面皿放置在温度25℃，湿度为75％的环境中24h，然后称量下述样品各1g，快速放入温度25℃，湿度为75％的环境中24h充分吸湿。结果如下：
Figure PCTCN2016099013-appb-000007
由上述试验数据可以看出：晶型I、晶型III、晶型IV不吸湿，稳定性良好，晶型II次之，CN201080031945晶型吸湿性最强。所以，本发明开发的新晶型不易与外界进行物质交换，能保持较好的稳定性。
另外，由图17中的晶习图片可以看出本发明的晶型I、晶型II和晶型IV呈菱形，晶型III成针状，晶型I、晶型II、晶型III和晶型IV的晶习规则，易于过滤、洗涤、能有效减少溶液在固体中的残留，有效提高了产品的纯度，降低溶剂残留，利于干燥，单位体积内的比表面积小，表面能低，与环境接触面小，有利于物质稳定。此外，本发明的晶型I与晶型II在制备过程中可以不使用有机溶剂，从而有效的避免了样品中的溶剂残留，降低了生产成本，减少了溶剂回收成本，该工艺更绿色环保。
综上所述，本发明的发明人经过大量研究发现了本发明的吡咯并喹啉醌二钠盐新晶型，其溶解性良好、结晶工艺简单、便于操作、污染小、可实现工业化生产，而且本发明的晶型药物同时具备产品纯度高、理化性质优异、化学稳定性良好、可加工(过滤、干燥、溶出和压片)再现的优点。
