抗耐甲氧西林金黄葡萄球菌的 (±)-marinopyrrole A及其合成衍生物 本申请要求于 2010 年 2 月 24 日提交中国专利局、 申请号为 201010113282.8、发明名称为"抗耐曱氧西林金黄葡萄球菌的(士)-marinopyrrole A及其合成衍生物"的中国专利申请的优先权, 其全部内容通过引用结合在本 申请中。 技术领域
本发明涉及用于治疗抗耐曱氧西林金黄葡萄球菌、曱氧西林敏感金黄葡萄 球菌、 表皮葡萄球菌、 耐万古霉素肠球菌等革兰氏阳性菌感染的天然产物 (士) -marinopyrrole A的合成 4汙生物。 jit夕卜 , 本发明还涉及 marinopyrrole A及其 新的合成衍生物的制备方法。 背景技术
抗生素耐药性的产生和治疗是困扰医学界多年的难题,其中由耐曱氧西林 金黄葡萄球菌 ( Methicillin-resistant Staphylococcus aureus, MRSA )导致的耐药 性更是近年来的医学难题之一。耐曱氧西林金黄葡萄球菌是由金黄葡萄球菌变 种而来的一种独特菌株, 可引起人类表皮、 软组织、 黏膜、 骨和关节等多种组 织器官的严重感染, 能抵抗包括曱氧西林及含 β-内酰胺结构的头孢抗生素。 该 病菌感染主要来源于医院 ( Hospital-associated MRSA , HA-MRSA ) , 于 1961 年在英国被首次发现后, 即以惊人的速度在世界范围内蔓延,每年至少有十万 人因感染 MRSA而住院治疗, 成为全世界医院内感染的主要病原菌。 而在医院 环境中, MRSA往往能抵御消毒剂的杀伤, 造成患者创口感染, 严重时甚至致 人死亡; 同时, 由于近年来广谱高效抗生素在临床的大量使用, MRSA的耐药 性明显增高, 使得 MRSA的治疗更显困难, 因此该病菌在医院内又被称作"超 级病菌"。 目前, MRS A感染已超过 AIDS、 结核和病毒性肝炎成为患者首位 致死原因, 近年来还出现了社区型 MRSA ( Community-associated MRSA , CA-MRSA )和耐万古霉素 (VRE ) 的相关才艮道, 严重威胁公共卫生安全。
鉴于耐曱氧西林金黄葡萄球菌对患者健康造成的巨大危害, 寻找对其具 有高效抑制活性的药物一直是医疗卫生和药物化学领域的研究热点之一。近年 来, 科学家们对 MRSA的耐药机制进行了大量的研究, 并发现了一些具有临床 应用价值的新化合物, 根据不同的抗菌机理, 目前治疗 MRSA感染的药物主 要可分为以下几大类 (Malina, S. I.; Andres, R.; Hartmut, L. Curr. Opin. Crit. Care 2^5, 77, 481 ): (一)、 糖肽类抗生素。 糖肽类抗生素是目前治疗 MRSA 感染的主要药物, 其代表药物有万古霉素 (vancomycin ) , 去曱万古霉素 ( norvancomycin )、 替考拉宁 ( teicoplanin )、 telavancin、 oritavancin和 dalbavancin。该类抗生素能与病菌细胞壁前体肽聚末端的丙氨酰丙氨酸高亲和 力结合, 阻断病菌细胞壁的主要成分高分子肽聚糖骨架的形成,从而抑制病 菌细胞壁的合成, 杀灭病菌。 其中 telavancin除能抑制细胞壁的合成外, 还能 破坏病菌细胞膜,从而降低细菌耐药性的产生( Projan, S. J.; Bradford, P. A.C rr. Opin. Microbiol. 2007, 10, 441 ); (二)、 噁唑烷酮类抗生素, 该类抗生素的主要 代表药物是利奈唑胺(linezolid )。 与其他抗生素通常作用于蛋白质合成的最 后阶段不同, 利奈唑胺主要抑制病菌蛋白质合成的第一阶段, 该药物能选择 性与病菌核糖体结合, 扰乱 mRNA的转录, 从而抑制病菌蛋白质的合成, 阻止 病菌的生长和增殖。 该药物也是首个被批准用于临床的噁唑烷酮类抗生素 ( Prasad, J. V. N. V. Curr. Opin. Microbiol. 2007, 10, 454 ); (三)、 β-内酰胺类抗 生素, 该类抗生素是目前研究最多的一类抗 MRSA感染药物, 其代表药物包 括 ceftobiprole、 ceftaroline等。 研究表明, 青霉素结合蛋白 2a ( PBP2a )是一种 特定的 MRSA结合蛋白, 该蛋白决定了金葡菌株的耐曱氧西林能力。 通常情况 下, PBP2a与 β-内酰胺抗菌素结合能力 4艮低, 使得 MRSA对大多数的 β-内酰胺 抗菌素耐药, 而 ceftobiprole和 ceftaroline则能高亲和力地与金黄色葡萄球菌的 青霉素结合蛋白 (PBP2a )结合, 阻止其细胞中肽聚糖的交联, 从而抑制细菌 细胞壁的合成 ( Kontou, P.; Kuti, J. L.; Nicolau, D. P. Formulary, 2008, 43, 66; Murthy B.; Schmitt-Hoffmann A. Clin. Pharmacokinet 2008, 47, 21 ; Jones, M. E. Clin. Microbiol. Infec. 2007, 73(Suppl 2), 17; Kanafani Z. A.; Corey, G. R. Future Microbiol. 2009, 4, 25; Zhanel, G. G. et al. Drugs, 2009, 69, 809 ); (四)、 脂肽类 抗生素, 其代表药物是达托霉素 ( daptomycin )。 达托霉素通过扰乱细胞膜对 氨基酸的转运,从而阻碍细菌细胞壁肽聚糖的生物合成,改变细胞质膜的性质; 同时, 它还能通过破坏细菌的细胞膜, 使其内容物外泄而达到杀菌的目的。 达 托霉素独特的作用机制使得细菌对其产生耐药性的可能性大大减低(Raja, A.; LaBonte, J.; Lebbos, J.; Kirkpatrick, P., Nature Rev. Drug Discov. 2003, 2, 943 ); (五)、 甘氨酰四环素类, 其代表药物是替加环素 ( tigecycline )。 该药物通过 与细菌 30S核糖体结合, 阻止 tRNA的进入, 干扰氨基酸肽链的形成, 进而阻断 病菌蛋白质的合成,限制病菌的生长;(六)、复方制剂。达福普丁( dalfopristin ) 和奎奴普丁( quinupristin )均作用于病菌的核糖体, 分别抑制蛋白质合成的早 期阶段和后期阶段, 两种联合应用时能表现出良好的协同作用, 从而有效地抗 MRSA感染。
如上所述, 虽然目前各大制药公司陆续开发出一些治疗 MRSA感染的新 型药物, 但迄今为止, 已在临床使用多年的糖肽类抗生素代表药物万古霉素 仍然是治疗 MRSA感染的一线治疗药物。 近年来, 随着耐万古霉素 MRSA 个案的出现和各种药物毒副作用的逐渐显现, 寻找新的具有抗 MRSA活性的 化合物已成为药物化学研究的热点之一。
对活性天然产物进行结构改造是发现新药的重要途径之一。 Fenical等人 2008 年从海洋链霉菌 (marine Streptomyces sp. ) 中提取的双吡咯化合物 marinopyrrole A和 marinopyrrole B为结构新颖的具有双比17各结构的天然产物。 活性筛选发现, 上述两种新化合物具有与万古霉素一致的抗 MRSA活性(对 MRSA: (-) -marinopyrrole A, (+)-marinopyrrole A和 (-) -marinopyrrole B的 MIC90 分别为 0.61 μΜ, 0.31 μΜ和 1.1 μΜ; 万古霉素的 MIC90为 0.14-0.27μΜ ), 是具 有良好药物开发前景的明星分子 ( William Fenical et al. Organic Lett. 2008, 10, 629 )。鉴于该类化合物重要的生物活性和药物开发价值, 一经发现即吸引了众 多药物学家的关注,但由于其骨架新颖, 目前尚未见相关合成及构效关系研究 报道。
