Abstract
本发明涉及可用于治疗细菌感染的新的式(I)化合物、其对映体、其非对映体、其可药用盐、或其前药。
Description
技术领域
本发明涉及新的式(I)化合物、其互变异构形式、其立体异构体、其可药用盐、包含它们的药物组合物、其制备方法。这些化合物显示出针对结核分枝杆菌(Mycobacteriumtuberculosis)感染的活性。
背景技术
结核(tuberculosis,TB)是世界上由感染性疾病导致的人死亡的主要原因之一。据认为,约33%的世界群体感染了导致TB病的病原体结核分枝杆菌(Mtb)(WHO“GlobalTuberculosis Report 2016”,世界卫生组织(World Health Organization),2017)。目前治疗具有治愈药物敏感性TB的潜力,然而,耐药性或多重耐药性TB(multi drug-resistantTB,MDR-TB)的治疗具有挑战性,并且需要组合化学治疗两年(WHO“Multidrug-ResistantTuberculosis(MDR-TB)2016Update”,世界卫生组织,2016)。对MDR-TB和广泛抗性TB(XDR-TB)的目前治疗的抗性凸显了对具有新作用机制的新药物的需求。
利奈唑胺(Linezolid)被批准为用于革兰氏阳性菌感染的抗生素。它还显示出针对结核分枝杆菌病原体的抗菌活性。利奈唑胺及其他唑烷酮类药剂通过与50S核糖体亚基的肽基转移酶中心结合并干扰氨酰基-tRNA的放置来抑制细菌蛋白质的合成。它们不与哺乳动物胞质核糖体结合,但与线粒体核糖体结合,这是与利奈唑胺及其他唑烷酮类相关的骨髓毒性的原因。TB的治疗是漫长的,这使得利奈唑胺不适合于治疗TB。因此,需要具有改善的安全谱的新的唑烷酮类,其可用于治疗TB。WO 2017015106描述了用于治疗结核的经取代的苯基唑烷酮。KR 101271224描述了含有双环基的唑烷酮衍生物,其具有针对包括多种抗性菌株在内的革兰氏阳性菌的抗菌活性。WO 2005054234描述了作为活性成分的新的经取代的哌啶基苯基唑烷酮衍生物和治疗细菌感染的方法。还公开了描述唑烷酮类抑制剂的另一些文献,包括WO 9323384、WO 2002080841、WO 2001042242、WO2005064415、WO 2009020616、WO 2017070024、WO 2005054234、WO 2002051819、WO2017156519、WO 2013044865和WO 2006059221。
发明内容
本发明公开了新的式(I)化合物。本发明的化合物通过调节细菌蛋白质的合成而可用于治疗人或动物体。因此,本发明的化合物适用于治疗结核或分枝杆菌(Mycobacterium)感染。

生物学评价:
最小抑制浓度(minimum inhibitory concentration,MIC)的确定
为了评估本发明化合物的细菌生长抑制作用,用结核分枝杆菌H37Rv的对数期培养物进行MABA测定。在7H9培养基中将光密度为0.6至0.8的细菌培养物稀释至最终密度为0.02。将100μl经稀释的结核分枝杆菌H37Rv与受试化合物在微量滴定板中孵育。还制备了也包含DMSO的无药物对照。将化合物与培养物在37℃下孵育7天之后,向每个孔中添加20μl的0.02%阿尔玛蓝(新鲜制备)。在37℃下进行显色16小时。孔中的蓝色表示无生长,而粉红色表示孔中的生长。MIC值定义为阻止颜色从蓝色改变为粉红色的最低浓度。在530nm激发和590nm发射下测量荧光。表2示出了所选化合物的MIC值。
