苯并脂肪环取代烷基胺类化合物及其用途 技术领域
本发明涉及药物化学和药物治疗领域,更具体地,本发明涉及一种苯并脂肪环取代烷基胺类化合物及其制备方法,以及其在制备金黄色葡萄球菌金黄色色素合成抑制剂类抗菌药物中的应用。
背景技术
金黄色葡萄球菌(Staphylococcus aureus,SA)是世界范围内导致医疗保健相关感染最常见的病原体。作为革兰氏阳性菌的代表,它是引起人类化脓感染中最常见的病原菌,可直接导致局部化脓感染、肺炎、伪膜性肠炎、心包炎、脑膜炎、败血症、脓毒症等全身感染。SA的感染可分医院获得性感染和社区获得性感染,后者的发现更增加了这种致病菌潜在的生物危害性和引起感染爆发的可能性。
目前,不仅发现了耐甲氧西林的金黄色葡萄球菌(Methicillin-resistant Staphylococcus aureus,MRSA),还出现了极高耐药性(XDR)和完全耐药性(TDR)的MRSA;甚至出现了万古霉素中度耐药的金黄色葡萄球菌(Vancomycin-intermediate Staphylococcus aureus,VISA)、糖肽类抗生素中度耐药的金黄色葡萄球菌(Glycopeptide-intermediate Staphylococcus aureus,GISA)和万古霉素耐药金黄色葡萄球菌(Vancomycin-resistant Staphylococcus aureus,VRSA)。因MRSA对多种抗菌药物耐药,导致感染治疗困难,病死率较高,濒临“无药可救”的状况,给临床治疗造成严重的困难。根据美国疾病预防控制中心(Centers for Disease Control,CDC)统计,每年大约有十万人因为感染MRSA而住院治疗,发展新的抗MRSA感染的抗菌药刻不容缓。
综上所述,本领域迫切需要研发出新型的抗菌药物作用靶点和新型的抗细菌感染药物,尤其是抗金黄色色素合成的抗菌药物。
