Description
技术领域
本发明属于药物学领域,涉及药物合成和药理学领域。更具体而言,涉及含有氮杂环的三氮唑类抗真菌化合物、其药物组合物及其制备方法和其在制备抗真菌药物中的用途。
背景技术
近十年以来,由于肿瘤发病率的持续增加、骨髓和器官移植手术的广泛开展以及免疫抑制剂和广谱抗生素使用的大幅度增加,由念珠菌、曲霉菌、新型隐球菌引起的深部真菌感染在临床上成为越来越普遍的问题。系统性深部真菌感染严重危及患者生命,死亡率高达50%以上,而现有的抗真菌药物存在抗菌谱窄、毒性较大、水溶性差等缺点,其耐药性问题也日趋严重,所以寻找新的、更理想的抗真菌药物一直是药物化学家关注的热点和难点课题。
目前临床使用的抗深部真菌感染药物包括多烯类、三氮唑类和新近发展起来的棘白菌素类。多烯类的代表药物是两性霉素B及其脂质体,其严重的副作用限制了其临床使用范围。氮唑类抗真菌药物是各类抗真菌药物中最大的一类,最初的氮唑类抗真菌药物由于其毒副作用,只能用于浅表性真菌感染的治疗。酮康唑是第一个可以口服的、用于治疗深部真菌感染的氮唑类抗真菌药物,但是仍然存在毒副作用大的问题。直到19世纪80年代,氟康唑和伊曲康唑的相继出现,成为第一代口服抗真菌药物。但是氟康唑抗菌谱窄且耐药性愈来愈严重,而伊曲康唑水溶性较差,生物利用度较低,水溶性差带来的另一个严重问题是这些药物必须制成特殊制剂才能口服有效,这大大增加了病人治病成本。伊曲康唑用于抢救重危病人的注射剂为增加水溶性必须加入环糊精,而环糊精会产生额外的副作用,尤其对肾功能不全者危害更大。第二代口服抗真菌药物,泊沙康唑于2006年上市,扩大了抗菌谱,但是其代谢性质和理化特性很不理想,特别是它的水溶性极低,从而导致其口服生物利用度很低,疗效受食物影响巨大,且病人个体差异很大,使其疗效稳定性大为降低[Expert Opin.Investig.Drugs.2009,18(9),1279-1295]。因此,目前急需寻找一种抗菌谱较广,生物利用度高且水溶性好、既能口服、又能注射给药的新型抗真菌药物[Bioorg.Med.Chem.Lett.2009,19,3559-3563]。
发明内容
