芳基烷唑类衍生物及其用途
技术领域
本发明属于药物合成领域,本发明涉及新的芳基烷唑类衍生物及其药学上可接受的盐、水合物、溶剂化物或其前药,它们的制备方法以及含有所述化合物的药物组合物。
背景技术
随着外部环境的恶化和药物的滥用,由各类致病真菌引发的感染(fungalinfections,IFI)快速上升,特别是其中的深部真菌病感染,它除了能够侵犯皮肤和皮下组织外,还会累及内部组织和器官,使其在临床上表现出死亡率高、治愈难度大的特点。此外,病原真菌出现耐药性的现象也越来越频繁,这进一步加大了治疗难度;当前的抗真菌药物随着应用时间的延长,已越来越难以满足临床的治疗需要,往往需要采用复杂的给药方案,患者因为多种药物相互作用或依从性差而使治疗风险成倍增加。据统计,全球每年死于由深部耐药真菌引起的感染人数已高达150万,接近于结核病引起的死亡率。
目前,市场上应用较为广泛的抗真菌药物主要是针对CYP51靶点开发的商品化抗真菌抑制剂,如唑类化合物。目前,CYP51抑制剂虽具有高效、复发率低的优点,但同时存在易产生耐药性和代谢毒性大的缺点,特别是它们均已出现的耐药性问题,一旦发生,极难克服,并且在真菌感染过程中带来的严重的炎症反应,极大的加剧了患者的痛苦。本发明人拟从COX-2抑制剂和CYP51抑制剂的分子结构出发,考察这两类抑制剂具有共同的结构特征,设计并合成了一系列新的芳基烷唑类衍生物,使其具有双靶点特性。经过体外活性筛选,表明该类化合物具有较高的抗真菌和耐药真菌的活性。
