Definitions
- the invention relates to the field of medicinal chemistry, in particular to a novel antibiotic and a preparation method, use and application thereof.
- Gram-positive bacterial infections are common and frequently-occurring, endangering human health.
- Gram-positive cocci infections have increased, the detection rate of methicillin-resistant Staphylococcus aureus (MRSA) has increased, and penicillin-resistant Streptococcus pneumoniae (PRSP) has spread in many countries and regions, resistant to glycopeptides and many others.
- MRSA methicillin-resistant Staphylococcus aureus
- PRSP penicillin-resistant Streptococcus pneumoniae
- VRE vancomycin-resistant enterococci
- multidrug-resistant tubercle bacilli increased.
- bacterial exposure to antibacterial drugs can be mutated to obtain drug resistance.
- the surviving bacteria have accumulated rich “combat experience” and become resistant varieties, and then evolved cross-resistance, multi-drug resistance, pan-drug resistance, and total resistance.
- Super bacteria such as medicine. Not long ago, a joint study by Chinese and foreign researchers published results in the new issue of the "Lancet Infectious Diseases" magazine. The study showed that there is a special gene, MCR-1, and the bacteria carrying the gene show strong resistance to polymyxin, and this resistance can be quickly transferred to other strains, which means a new The "super bacteria” were discovered.
- carbapenem antibiotics are recognized as the "ultimate line of defense" of bacteria, and are often used to treat severely resistant bacteria. Heavy infection.
- carbapenem-resistant bacteria have caused serious bacterial resistance problems through inter-plasmid propagation, including the recently discovered colistin resistance.
- These life-saving drugs are often limited in clinical use because of their high toxicity. Therefore, there is a need to provide a novel antibacterial compound.
- the invention proposes a compound.
- the compound is a stereoisomer, a tautomer, an oxynitride, a hydrate, a solvate, a metabolite, or a metabolite of a compound of formula I or a compound of formula I,

优先权信息
本申请请求2017年05月22日向中国国家知识产权局提交的、专利申请号为201710363824.9的专利申请的优先权和权益,并且通过参照将其全文并入此处。
本发明涉及药物化学领域,具体地,本发明涉及一种新型抗生素及其制备方法、用途、应用。
革兰氏阳性细菌感染为常见病与多发病,危害人类健康。近年来,革兰氏阳性球菌感染日见增多,耐甲氧西林金黄色葡萄球菌(MRSA)检出率上升,耐青霉素肺炎链球菌(PRSP)在许多国家与地区传播,耐糖肽和其他多种抗生素的耐万古霉素肠球菌(VRE)出现,耐多药性结核杆菌有增无减。为了有效地控制此等现有抗生素与抗菌药的耐药菌感染,研究开发治疗革兰氏阳性耐药菌感染的药物已成为举世关注的点。
目前细菌接触抗菌药物可发生变异而获得耐药性,其机制主要有4种:①产生抗生素酶,灭活抗生素;②作用靶位变异,不应答药物;③外膜通透性改变,阻断药物进入;④增强外排,加速泵出进入菌体内的药物。在与抗菌药物一次次的“遭遇战”中,存活下来的细菌都积累了丰富的“战斗经验”,成为耐药品种,尔后又演进出交叉耐药、多重耐药、泛耐药、全耐药等“超级细菌”。不久前,一项由中外研究者联合进行的、成果发表在新一期《柳叶刀·传染病》杂志上的研究引发关注。该研究显示:存在一种特殊基因MCR-1,携带该基因的细菌对多粘菌素表现出强耐药性,且这种耐药性还能快速转移至其他菌株,这意味着一种新的“超级细菌”被发现。
2015年,我国大肠埃希菌对第三代头孢菌素的耐药菌检出率为59%,对喹诺酮类的耐药菌检出率为53.5%。肺炎克雷伯菌对第三代头孢菌素的耐药菌检出率是36.5%,甲氧西林耐药金黄色葡萄球菌检出率为35.8%,这些具有代表性的耐药菌检出率都处于较高水平。需要指出的是,万古霉素耐药屎肠球菌已成为发达国家的一大挑战,美国ICU患者的血流感染屎肠球菌万古霉素耐药率高达80.7%。全球来看,北美洲屎肠球菌万古霉素耐药平均检出率高达66.8%,拉丁美洲为39.4%。一些多重耐药、泛耐药的细菌已将临床逼到了绝境,加速研发新型抗菌药物迫在眉睫。
目前,碳青霉烯类抗生素是公认的细菌“终极防线”,常用于治疗由多重耐药菌引起严
重感染。近几年,碳青霉烯类耐药菌通过质粒间传播造成了严重的细菌耐药问题,包括近期发现的粘菌素耐药。这些救命药因其毒性较大,往往临床使用受限。因此,需要提供一种结构新颖的抗菌化合物。

除非另外说明,本发明所使用的所有科技术语具有与本发明所属领域技术人员的通常理解相同的含义。本发明涉及的所有专利和公开出版物通过引用方式整体并入本发明。
除非另外说明,应当应用本文所使用得下列定义。出于本发明的目的,化学元素与元素周期表CAS版,和《化学和物理手册》,第75版,1994一致。此外,有机化学一般原理可参考"Organic Chemistry",Thomas Sorrell,University Science Books,Sausalito:1999,和"March's Advanced Organic Chemistry”by Michael B.Smith and Jerry March,John Wiley&Sons,New York:2007中的描述,其全部内容通过引用并入本文。
除非另有说明或者上下文中有明显的冲突,本文所使用的冠词“一”、“一个(种)”和“所述”旨在包括“至少一个”或“一个或多个”。因此,本文所使用的这些冠词是指一个或多于一个(即至少一个)宾语的冠词。例如,“一组分”指一个或多个组分,即可能有多于一个的组分被考虑在所述实施方案的实施方式中采用或使用。
术语“包含”为开放式表达,即包括本发明所指明的内容,但并不排除其他方面的内容。
“立体异构体”是指具有相同化学构造,但原子或基团在空间上排列方式不同的化合物。立体异构体包括对映异构体、非对映异构体、构象异构体(旋转异构体)、几何异构体(顺/反)异构体、阻转异构体,等等。
“手性”是具有与其镜像不能重叠性质的分子;而“非手性”是指与其镜像可以重叠的分子。
“对映异构体”是指一个化合物的两个不能重叠但互成镜像关系的异构体。
“非对映异构体”是指有两个或多个手性中心并且其分子不互为镜像的立体异构体。非对映异构体具有不同的物理性质,如熔点、沸点、光谱性质和反应性。非对映异构体混合物可通过高分辨分析操作如电泳和色谱,例如HPLC来分离。
本发明所使用的立体化学定义和规则一般遵循S.P.Parker,Ed.,McGraw-Hill Dictionary of Chemical Terms(1984)McGraw-Hill Book Company,New York;and Eliel,E.and Wilen,S.,“Stereochemistry of Organic Compounds”,John Wiley&Sons,Inc.,New York,1994。
许多有机化合物以光学活性形式存在,即它们具有使平面偏振光的平面发生旋转的能力。在描述光学活性化合物时,使用前缀D和L或R和S来表示分子关于其一个或多个手性中心的绝对构型。前缀d和l或(+)和(-)是用于指定化合物所致平面偏振光旋转的符号,其中(-)或l表示化合物是左旋的。前缀为(+)或d的化合物是右旋的。一种具体的立体异构体是对映异构体,这种异构体的混合物称作对映异构体混合物。对映异构体的50:50混合物称为外消旋混合物或外消旋体,当在化学反应或过程中没有立体选择性或立体特异性时,可出现这种情况。
本发明公开化合物的任何不对称原子(例如,碳等)都可以以外消旋或对映体富集的形式存在,例如(R)-、(S)-或(R,S)-构型形式存在。在某些实施方案中,各不对称原子在(R)-或(S)-构型方面具有至少50%对映体过量,至少60%对映体过量,至少70%对映体过量,至少80%对映体过量,至少90%对映体过量,至少95%对映体过量,或至少99%对映体过量。
依据起始物料和方法的选择,本发明化合物可以以可能的异构体中的一个或它们的混合物,例如外消旋体和非对映异构体混合物(这取决于不对称碳原子的数量)的形式存在。光学活性的(R)-或(S)-异构体可使用手性合成子或手性试剂制备,或使用常规技术拆分。如果化合物含有一个双键,取代基可能为E或Z构型;如果化合物中含有二取代的环烷基,环烷基的取代基可能有顺式或反式构型。
所得的任何立体异构体的混合物可以依据组分物理化学性质上的差异被分离成纯的或基本纯的几何异构体,对映异构体,非对映异构体,例如,通过色谱法和/或分步结晶法。
可以用已知的方法将任何所得终产物或中间体的外消旋体通过本领域技术人员熟悉的方法拆分成光学对映体,如,通过对获得的其非对映异构的盐进行分离。外消旋的产物也可以通过手性色谱来分离,如,使用手性吸附剂的高效液相色谱(HPLC)。特别地,对映异构体可以通过不对称合成制备,例如,可参考Jacques,et al.,Enantiomers,Racemates and Resolutions(Wiley Interscience,New York,1981);Principles of Asymmetric Synthesis(2nd Ed.Robert E.Gawley,Jeffrey Aubé,Elsevier,Oxford,UK,2012);Eliel,E.L.Stereochemistry of Carbon Compounds(McGraw-Hill,NY,1962);Wilen,S.H.Tables of Resolving Agents and Optical Resolutions p.268(E.L.Eliel,Ed.,Univ.of Notre Dame Press,Notre Dame,IN 1972);Chiral Separation Techniques:A Practical Approach(Subramanian,G.Ed.,Wiley-VCH Verlag GmbH&Co.KGaA,Weinheim,Germany,2007)。
术语“互变异构体”或“互变异构形式”是指具有不同能量的可通过低能垒(low energy
barrier)互相转化的结构异构体。若互变异构是可能的(如在溶液中),则可以达到互变异构体的化学平衡。例如,质子互变异构体(protontautomer)(也称为质子转移互变异构体(prototropic tautomer))包括通过质子迁移来进行的互相转化,如酮-烯醇异构化和亚胺-烯胺异构化。价键互变异构体(valence tautomer)包括通过一些成键电子的重组来进行的互相转化。酮-烯醇互变异构的具体实例是戊烷-2,4-二酮和4-羟基戊-3-烯-2-酮互变异构体的互变。互变异构的另一个实例是酚-酮互变异构。酚-酮互变异构的一个具体实例是吡啶-4-醇和吡啶-4(1H)-酮互变异构体的互变。除非另外指出,本发明化合物的所有互变异构体形式都在本发明的范围之内。
像本发明所描述的,本发明的化合物可以任选地被一个或多个取代基所取代,如上面的通式化合物,或者像实施例里面特殊的例子,子类,和本发明所包含的一类化合物。应了解“任选取代的”这个术语与“取代或非取代的”这个术语可以交换使用。一般而言,术语“取代的”表示所给结构中的一个或多个氢原子被具体取代基所取代。除非其他方面表明,一个任选的取代基团可以在基团各个可取代的位置进行取代。当所给出的结构式中不只一个位置能被选自具体基团的一个或多个取代基所取代,那么取代基可以相同或不同地在各个位置取代。
另外,需要说明的是,除非以其他方式明确指出,在本发明中所采用的描述方式“各…独立地为”与“…各自独立地为”和“…独立地为”可以互换,均应做广义理解,其既可以是指在不同基团中,相同符号之间所表达的具体选项之间互相不影响,也可以表示在相同的基团中,相同符号之间所表达的具体选项之间互相不影响。
在本说明书的各部分,本发明公开化合物的取代基按照基团种类或范围公开。特别指出,本发明包括这些基团种类和范围的各个成员的每一个独立的次级组合。例如,术语“C1-6烷基”特别指独立公开的甲基、乙基、C3烷基、C4烷基、C5烷基和C6烷基。
在本发明的各部分,描述了连接取代基。当该结构清楚地需要连接基团时,针对该基团所列举的马库什变量应理解为连接基团。例如,如果该结构需要连接基团并且针对该变量的马库什基团定义列举了“烷基”或“芳基”,则应该理解,该“烷基”或“芳基”分别代表连接的亚烷基基团或亚芳基基团。

另外,本发明公开的化合物,包括它们的盐,也可以以它们的水合物形式或包含其溶剂(例如乙醇、DMSO,等等)的形式得到,用于它们的结晶。本发明公开化合物可以与药学上可接受的溶剂(包括水)固有地或通过设计形成溶剂化物;因此,本发明旨在包括溶
剂化的和未溶剂化的形式。
本发明给出的任何结构式也意欲表示这些化合物未被同位素富集的形式以及同位素富集的形式。同位素富集的化合物具有本发明给出的通式描绘的结构,除了一个或多个原子被具有所选择原子量或质量数的原子替换。可引入本发明化合物中的示例性同位素包括氢、碳、氮、氧、磷、硫、氟和氯的同位素,如2H,3H,11C,13C,14C,15N,17O,18O,18F,31P,32P,35S,36Cl和125I。

此外,较重同位素特别是氘(即,2H或D)的取代可提供某些治疗优点,这些优点是由代谢稳定性更高带来的。例如,体内半衰期增加或剂量需求降低或治疗指数得到改善带来的。应当理解,本发明中的氘被看做式(I)化合物的取代基。可以用同位素富集因子来定义该类较重同位素特别是氘的浓度。本发明所使用的术语“同位素富集因子”是指所指定同位素的同位素丰度和天然丰度之间的比例。如果本发明化合物的取代基被指定为氘,该化合物对各指定的氘原子而言具有至少3500(各指定氘原子处52.5%的氘掺入)、至少4000(60%的氘掺入)、至少4500(67.5%的氘掺入),至少5000(75%的氘掺入),至少5500(82.5%的氘掺入)、至少6000(90%的氘掺入)、至少6333.3(95%的氘掺入)、至少6466.7(97%的氘掺入)、至少6600(99%的氘掺入)或至少6633.3(99.5%的氘掺入)的同位素富集因子。本发明可药用的溶剂化物包括其中结晶溶剂可以是同位素取代的例如D2O、丙酮-d6、DMSO-d6的那些溶剂化物。
另一方面,本发明涉及制备式(I)所包含的化合物的中间体。
另一方面,本发明涉及式(I)所包含的化合物的制备、分离和纯化的方法。
另一方面,本发明提供一种药物组合物,所述药物组合物包含本发明化合物,药学上可接受的载体,赋形剂,稀释剂,辅剂,溶媒,或它们的组合。在一些实施方案,药物组合物可以是液体,固体,半固体,凝胶或喷雾剂型。
“联合”表示在单个剂量单位形式中的固定组合或用于组合施用的部分的药盒,其中本发明公开化合物和组合伴侣可以在同一时间独立施用或者可以在一定的时间间隔内分别施
用,特别是使联合合伴侣表现出合作、例如协同作用。如本文所用的术语“共同给药”或“联合给药”等意欲囊括将所选的组合伴侣施用于需要其的单个个体(例如患者),并且意欲包括其中物质不必通过相同施用途径或同时施用的治疗方案。如本文所用的术语“药物组合产品”表示将一种以上活性成分混合或组合所得到的产品,并且既包括活性成分的固定组合也包括非固定组合。术语“固定联合”表示活性成分如本发明公开化合物和组合伴侣以单一实体或剂量的形式同时施用于患者。术语“非固定联合”表示活性成分如本发明公开化合物化合物和组合伙伴均作为单独实体同时、共同或无特定时间限制地先后施用于患者,其中该施用在患者体内提供了两种化合物的治疗有效水平。后者还适用于鸡尾酒疗法,例如施用3种或更多种活性成分。
下面详细描述本发明的实施例,下面描述的实施例是示例性的,旨在用于解释本发明,而不能理解为对本发明的限制。
下述实施例中所使用的实验方法如无特殊说明,均为常规方法。
下述实施例中所用的材料、试剂等,如无特殊说明,均可从商业途径得到。
