Description

泊沙康唑杂质对照品及其制备方法 技术领域
本发明涉及医药技术领域,具体涉及泊沙康唑杂质对照品及其制备方法。
背景技术
泊沙康唑,其化学名为4-[4-[4-[4-[[(3R,5R)-5-(2,4-二氟苯基)-5-(1,2,4-三唑-1-基甲基)氧杂戊环-3-基]甲氧基]苯基]哌嗪-1-基]苯基]-2-[(2S,3S)-2-羟基戊-3-基]-1,2,4-三唑-3-酮,是一种新型的第二代广谱三唑类抗真菌。该药物由德国先灵葆雅公司研制,于2005年10月20日德国最先批准上市,随后陆续在美国,欧洲市场获得批准上市。其商品名为Noxafil,目前上市的剂型有注射剂,口服肠溶片,混悬剂等。该药物临床上主要用于治疗侵袭性真菌感染。
Figure PCTCN2021141577-appb-000001
泊沙康唑在临床上有着广泛的使用,若药物中潜在未被有效控制的杂质,将会导致临床上不良反应事故发生的风险。因此,对药品中的有关物质进行规范的合成研究和药理分析将有利于控制原料药及其制剂的质量和安全性。
目前国内外研发、生产泊沙康唑的厂家较多,生产工艺大同小异,对其质量研究、控制的程度各不相同,其中主流的工艺合成路线有专利WO 2009141837、WO9633178等。文献/专利报道通用的合成路线采用化合物6和化合物2拼接而成:
Figure PCTCN2021141577-appb-000002
通过对泊沙康唑原料药的分析发现泊沙康唑原料中存在少量如下2个杂质:有关物质A和有关物质B。
Figure PCTCN2021141577-appb-000003
通过制备色谱的手段从泊沙康唑中分离得到有关物质A和B的难度较大,主要原因是有关物质A和有关物质B在泊沙康唑中的残留量<0.10%,这极大的增加了昂贵的原料药消耗和制备工时。
