Abstract
本发明公开了一种卡泊芬净类似物的制备方法和用途。所述的卡泊芬净类似物的结构如式3所示。
Description
技术领域
本发明涉及有机化合物领域,尤其涉及一种卡泊芬净类似物及其制备方法和用途。
背景技术
1974年,人们发现了棘白菌素类化合物具有良好的抗菌活性。从此以后,人们研究了许多半合成的棘白菌素类化合物的药理活性。直至2001年,卡泊芬净正式得到美国FDA的批准上市,人们对抗真菌的药物的研究得到了突破性的进展。卡泊芬净是一个作用位点独特,广谱且低毒的药物,其化学结构如式1所示:
WO94/21677、EP620232、WO96/24613、US5552521、WO97/47645、US5936062、WO02/083713、J.Org.Chem.,2007,72,2335-2343、CN101792486A、CN101648994A、WO2010008493A2、US2010168415A1、EP1785432、WO2010064219A1、描述了卡泊芬净类似物和卡泊芬净的制备方法。
WO94/21677和EP620232以Pneumocandin B0为起始原料,与烷基硫醇或芳基硫醇反应,然后经过氧化得到砜中间体,再与胺化合物在无水的非质子溶剂中反应,所得反应产物再通过色谱方法分离得到。
WO96/24613和US5552521将Pneumocandin B0的伯酰胺基还原为胺基基团,收率为47%,然后与苯硫酚反应,再与乙二胺反应得到卡泊芬净。
WO97/47645、US5936062和J.Org.Chem.,2007,72,2335-2343报道了以Pneumocandin B0为起始原料制备卡泊芬净的两种立体选择性方法。第一种方法以苯基硼酸酯为保护基,然后将Pneumocandin B0酰胺基团还原为相应的胺基,再依次与苯硫酚和乙二胺反应得到卡泊芬净;第二种方法以Pneumocandin B0为起始原料与苯硫酚反应,然后经过苯基硼酸酯保护,再通过将PneumocandinB0酰胺基团还原为相应的胺基后与乙二胺反应得到卡泊芬净。
CN101792486A和CN 101648994A公开了以Pneumocandin B0为起始原料,在苯基硼酸酯保护的条件下与乙二胺反应,再将所得的中间体的酰胺基团还原为相应的胺基得到卡泊芬净;
WO02/083713、US2010168415A1、EP1785432、WO2010064219A1、WO2010064219A1公开了制备Pneumocandin B0氰基化合物的中间体,再通过氢气还原得到卡泊芬净。
WO2010008493A2以Pneumocandin B0为起始原料与4-甲氧基苯硫酚反应,然后经过苯基硼酸酯保护,并在3A分子筛脱水的条件下,将Pneumocandin B0酰胺基团还原为相应的胺基,再与乙二胺反应得到卡泊芬净。
然而,就产率、纯度、稳定性以及三废而言,已公开的方法不是用于工业化生产的最佳方法。制备柱色谱步骤的多次使用,使得工业化成本大量增加,产生大量的三废;一些方法必须在严格的无水条件下(例如采用3A分子筛脱水)操作;多数方法均使用到具有恶臭的剧毒品苯硫酚,操作难度系数大,损害操作人员健康,严重污染环境;此外,部分已有的合成方法中,制备Pneumocandin B0类氰基化合物时不可避免的导致异构体生成,立体选择性和收率不高,同时使用到昂贵金属作为催化剂,导致工业化成本高。因此,迫切需要进一步研究适合工业化生产的制备卡泊芬净的方法。
