Abstract
一种新型的头孢菌素化合物(式I)或其药理学上可接受的盐。通式(I)中的R1和R2可以相同也可以不同,它们分别为氢,C1-5的低级烷基,苯基或取代了的苯基,A为氢或一个亲核化合物的残基。上述化合物和其盐对革兰氏阳性或革兰氏阴性微生物具有良好的抗菌活性。
Description
本发明是关于一种新型具有广谱抗菌活性(包括对绿脓假单胞菌的抗菌活性)的头孢菌素化合物及其制备方法。本发明特别涉及一种新型头孢菌素衍生物,其中7-位上带有(Z)-2-(2-氨基噻唑-4-基)-2-(1,5-二羟基-4-吡啶酮-2-基)烷氧基亚氨基乙酰胺基,该衍生物对于由病原体导致的人类和各种动物的疾病有良好的治疗作用,因此可用做医药和兽药。
头孢菌素抗菌素广泛用于治疗由病原菌导致的疾病,但是在抗菌能力、抗菌谱、临床药理效果等方面都很难令人满意。
本发明者以前发现:在7-位上带有2-(2-氨基噻唑-4-基)-2-(1,5-二羟基-4-吡啶酮-2-甲酰胺基)乙酰胺基的新型头孢菌素衍生物对于多种病原体有很强的抗菌作用。该发现描述在日本专利申请60-140989、61-77893和61-77894中。这些衍生物特别是对绿脓假单孢菌有很强的抗菌能力。据认为,该抗菌活性来自在7-位上的1,5-二羟基-4-吡啶酮-2-甲酰胺基取代基。通过进一步研究该衍生物上的1,5-二羟基-4-吡啶酮结构,并特别侧重在7-位上支链的研究,终于发现了对革兰氏阴性菌(包括绿脓假单胞菌)具有广谱抗菌作用的新型头孢菌素化合物(式Ⅰ),该化合物对制造β-内酰胺酶的各种细菌有特别强的抗菌活性,由此完成了本发明。
本发明是关于可用做抗菌剂的具有通式(Ⅰ)的头孢菌素化合物及其药理上可接受的盐,和含这些化合物或盐作为活性组份的抗菌剂,
其中R1和R2是氢原子、1至5个碳原子的低级烷基、苯基或被取代的苯基,它们可以相同或不同,A是氢原子或亲核化合物残基。
通式(Ⅰ)化合物是顺式异构体,而在7-位取代基上有一个不对称碳原子时,D-构型和L-构型也可以存在。但是本发明既不包括D和L构型,也不包括DL构型。另外,作为7-位取代基的1,5-二羟基-4-吡啶-2-烷氧亚氨基部分可以下面所示的互变异构体形式存在。尽管本发明包括上述两种异构体,但还是用“吡啶酮式”这一术语表述该结构。
本发明式(Ⅰ)化合物的药理上可接受盐的例子包括医用盐,特别是常用的无毒性盐,例如碱金属盐(如钠盐、钾盐等)、碱土金属盐(如钙盐、镁盐等)、铵盐、与有机碱形成的有机盐(例如有机铵盐,如三乙胺盐、吡啶盐、乙醇胺盐、三乙醇胺盐、二环己胺盐)、碱性氨基酸盐(例如与赖氨酸或精氨酸等形成的盐)。
通式(Ⅰ)化合物中用A表示的亲核化合物残基的例子包括羟基、巯基、氨基甲酰基、氨基甲酰氧基、叠氮基、2至5个碳原子的烷酰氧基,或季铵基,如下式的吡啶鎓或取代的吡啶鎓基:
其中n是零或整数3至5,R3和R4可以相同或不同并且是氢原子、囟原子、1至5个碳原子的直链或支链烷基、羟基、氨基、氨基甲酰基、磺酸基、亚磺酰氨基、磺烷基、1至5个碳原子的直链或支链烷硫基、囟代烷硫基、环烷硫基、环烷甲硫基、羧烷硫基、烷氧烷硫基或被烷基取代的氨基烷硫基,以及可被任意取代的喹啉鎓、异喹啉鎓、噻唑啉鎓、N-烷基吡咯烷鎓等,或者由硫相连的杂环,即杂环硫基,或苯基,与硫基相连的被取代的苯基。
这里所说的杂环是指含有1至4个选自O、S和N的杂原子的5元或6元环,如吡啶基、N-氧吡啶基、嘧啶基、哒嗪基、N-氧哒嗪基、吡唑基、二唑基、噻唑基、噻二唑基、噁二唑基、***基、四唑基、三嗪基等,或双环杂环,例如环烯并吡啶基、苯并噻唑基、苯并咪唑基、苯并恶唑基、三氮杂茚基等。上述杂环可以带有取代基,如1至3个碳原子的低级烷基、囟代烷基、烷氧基、囟原子、羟基、巯基、氨基、羧基、氨基甲酰基、低级烷基氨基-低级烷基(含1至3个碳原子)、羧甲基、羟烷基、磺烷基、烷巯基、烷氧羰基等。
A表示下式的吡啶鎓硫基或被取代的吡啶鎓硫基:
式中n是零或3至5的整数,R5和R6可以相同或不同,它们是氢原子、囟原子或可以含囟原子的1至5个碳原子的低级烷基,R7表示1至5个碳原子的直链或支链烷基、囟代烷基、环丙基、环丙甲基、链烯基、氧原子或-(CH2)m B(其中m是0至3的整数,B是羟基)、烷氧基、氨基、被烷基取代的氨基、羧基、氨基甲酰基、磺酸基、磺酰氨基、异羟肟酸基、氰基、硫羟基、烷硫基、甲磺酰氨基羰基或乙酰氨基磺酰基。

本发明者根据日本专利申请60-140989公开的方法合成了保护形式的2-羟甲基-1,5-二羟基-4-吡啶酮,该化合物是7-位取代基的构成体之一。即可以通过使被保护的曲酸(Ⅱ)与盐酸羟胺或R9ONH2(或其盐)在吡啶等存在下进行反应而得到该化合物,
式中R8和R9是可脱除的保护基,如苄基、对硝基苄基、邻硝基苄基、对甲氧苄基、二苯甲基等。
此外,式(Ⅲ)化合物与R9X(其中X是囟原子或重氮基)反应,在不同的R9X,反应溶剂及反应条件(如温度)下,可以得到产物(Ⅳa)或(Ⅳb),或其混合物。
本发明的头孢菌素化合物(通式Ⅰ)可以通过下述方法A)或B)得到。
A)使通式(Ⅴa)化合物或(Ⅴb)化合物或此种羧酸的易反应衍生物与通式(Ⅵ)化合物或其盐,或其甲硅烷基化产物反应,然后脱去保护基。
式(Ⅴa)和(Ⅴb)中,R10是氢原子或氨基的保护基,R1、R2、R8和R9的定义同上;或(Ⅵ)中,R11是氢原子或羧基保护基,A的定义同上。
B)使通式(Ⅶa)或(Ⅶb)化合物与一种亲核化合物反应,然后如果需要则除去保护基,得到通式(Ⅰ)化合物。
式中Y是乙酰氧基或囟原子;R8′是氢原子或R8;R9′是氢原子或R9;R1、R2、R8、R9、R10和R11的定义同上。这里的亲核化合物是与通式(Ⅰ)中A相应的化合物。
对于上述通式中氨基和羧基的保护基,宜采用在β-内酰胺和肽合成领域使用的有关保护基。
氨基保护基的例子有甲酰、邻苯二甲酰、一氯乙酰、二氯乙酰、三氯乙酰、甲氧羰基、乙氧羰基、叔丁氧羰基、三氯乙氧羰基、苄氧羰基、对硝基苄氧羰基、二苯甲氧羰基、甲氧甲氧羰基、三苯甲基、三甲基硅基等。羧基保护基例子有叔丁基、叔戊基、烯丙基、苄基、对硝苄基、对甲氧苄基、二苯甲基、苯基、对硝苯基、甲氧甲基、乙氧甲基、苄氧甲基、乙酰氧甲基、甲硫甲基、三苯甲基、三氯乙基、三甲基硅基、二甲基甲硅烷基等。
在方法A中通式(Ⅴa)或(Ⅴb)与(Ⅵ)化合物的缩合反应可采用通常用于青霉素和头孢菌素酰化的方法进行。
上述易反应衍生物的例子包括酰囟、酸酐、活性酰胺、活性酯等。较好的例子有酰氯、酰溴,下述酸的混合酸酐,如:乙酸、新戊酸、异戊酸、三氯乙酸等,与吡唑、咪唑、二甲基吡唑、苯并***等形成的活泼酰胺,对硝基苯酯、2,4-二硝基苯酯、三氯苯酯等活泼酯,以及与1-羟基-1H-吡啶酮、N-羟基丁二酰亚胺、N-羟基苯并***、N-羟基邻苯二甲酰亚胺等形成的活泼酯。
另外,在此反应中,如果使用游离酸形式的式(Ⅴa)或式(Ⅴb)化合物,则最好在缩合剂存在下进行反应,也就是说,此反应可在一种缩合剂存在下进行,此缩合剂例如是碳化二亚胺[例如N,N-二环己基碳化二亚胺、N-环己基-N′-吗啉代乙基碳化二亚胺、N-环己基-N′-(4-二乙基氨基环己基)碳化二亚胺等)或酰胺(如N-甲基甲酰胺,N,N-二甲基甲酰胺等]与囟化物(如亚硫酰氯、磷酰氯、碳酰氯等)反应而生成的试剂[所谓的维斯米尔(Vilsmeiev)试剂]。
上述反应如果使用上述易反应衍生物中的酰囟或酸酐,则需要在酸结合剂存在下进行。酸结合剂的例子有包括有机碱,如三乙胺、三甲胺、乙基异丙胺、N,N-二甲胺、N-甲基吗啉、吡啶等;如钠、钾、钙等的氢氧化物;碱金属盐,如碱金属碳酸盐及酸式碳酸盐等;还有环氧化合物,如环氧乙烷、环氧丙烷等。
该反应通常在对反应无不良影响的溶剂中进行。溶剂的例子有水、丙酮、乙腈、二噁烷、四氢呋喃、乙酸乙酯、二氯甲烷、氯仿、二氯乙烷、N,N-二甲基甲酰胺、N,N-二甲基乙酰胺、二甲亚砜或它们的混合物。
对反应温度没有特别的限制,但反应一般在-30℃~40℃进行;至于反应时间,此反应一般进行30分钟到10小时便可完成。
将所得酰化产物的保护基脱除时,根据不同的保护基,可选择酸法、碱法、肼法等,按照β-内酰胺和肽合成领域中常用的方法进行。
使通式(Ⅷ)化合物或其盐与(Ⅸa)化合物或(Ⅸb)化合物反应,然后根据需要脱除羧基保护基,可得到式(Ⅴa)或(Ⅴb)化合物。
式(Ⅷ)中R10和R11的定义同上;
式(Ⅸa)和(Ⅸb)中,Z是囟原子或磺酸根,如甲磺酰氧基、甲苯磺酰氧基、三氟甲磺酰氧基等。
该缩合反应可在-50℃~70℃下及溶剂中进行,如果需要亦可在碱存在下进行。其中碱和溶剂可选用方法A的酰化反应所用的碱和溶剂。方法B中通式(Ⅶa)和(Ⅶb)化合物与亲核化合物的反应可按头孢菌素化学中常用方法进行。也就是说,如果通式(Ⅶa)或(Ⅶb)中的Y是乙酰氧基,则反应一般是最好在极性溶剂中进行,该溶剂的例子包括水、磷酸盐缓冲液、丙酮、乙腈、N,N-二甲基甲酰胺、N,N-二甲基乙酰胺、四氢呋喃、二甲亚砜、二噁烷、甲醇、乙醇等或上述溶剂与水的混合物。
反应最好在接近中性条件下进行。尽管反应温度并不很苛刻,但合适的温度是室温至约80℃。
反应时间取决于反应条件,一般为1~10小时。
另外,碱金属囟化物(如碘化物、碘化钾等)的存在可以促进反应进行。
如果由Y为囟原子的式(Ⅶa)或(Ⅶb)化合物制备所需产物,则反应最好在无水条件下和下述溶剂中进行:丙酮、二噁烷、四氢呋喃、乙酸乙酯、乙腈、N,N-二甲基甲酰胺、N,N-二甲基乙酰胺、二甲亚砜等。反应温度最好为0~50℃;反应完成需时为1~5小时。
按上述方法得到的式(Ⅰ)化合物可用常规方法使之从反应混合物中分离出来。例如,可以适当地结合使用采用吸收树脂的提纯,沉淀,结晶等方法进行分离,其中树脂的例子有Amberlite XAD-2(由Rohm和Haas公司生产),Diaion HP-20(由三菱化学公司生产)。
含有通式(Ⅰ)化合物或其盐作为主要成分的抗菌剂可以各种药物剂型使用,例如有注射液(如静脉注射液、肌内注射液等)、口服剂(如胶囊、片剂、粉剂等)以及肠内用药、含油栓剂、水溶性栓剂等等。按照常规方法,采用常规赋形剂、填充剂、粘合剂、湿润剂、崩解剂、表面活性剂、润滑剂、分散剂、缓冲剂、保存剂、助溶剂、防腐剂、甜味剂、止痛剂等制备这些剂型。生产方法的具体例子在以下实施例有更详细的描述。
适宜的用药量应根据各个病人的病症严重程度、年龄、性别等来确定,但举例来说,成人的日用剂量一般为250~3000mg,每天分1~4次用药。
通过以下实施例更详细地叙述本发明,但应指出,这些实施例只是一些例子而已,在本发明范围内还可以作出各种改变及改进。
在这些实施例中,核磁共振谱(NMR)数据(δ值)在是用400兆赫核磁共振仅测得的。在使用重水溶剂时,δ值是以水的峰值(取为4.82)作标准;在使用其它氘化溶剂时,δ值是以TMS(四甲基甲硅烷)作为标准。
