Description

【0001】
【産業上の利用分野】
本発明は抗菌剤として有用な新規セフェム化合物及びその医薬として許容される塩並びにその製造法、更にはこれらを有効成分とする抗菌剤に関する。
【0002】
【従来の技術】
医療現場における感染症起因菌の変遷に対応する様に種々のセファロスポリン系抗菌剤が合成されてきた。これらセファロスポリン系抗菌剤に用いられてきた側鎖は3位側鎖、7位側鎖に大別でき、3位側鎖としては芳香族4級アンモニウム、硫黄原子を介した芳香族ヘテロ環あるいは硫黄原子を介した芳香族4級アンモニウムが多くの場合導入されている。また7位側鎖には2−(2−アミノチアゾール−4−イル)−2−置換オキシイミノアセトアミド基又は2−(5−アミノ−1,2,4−チアジアゾール−3−イル)−2−置換オキシイミノアセトアミド基が用いられており、その置換オキシイミノ部は置換低級アルキル基が導入されていることが多い。置換低級アルキル基上の置換基としてはハロゲン原子、カルボキシル基、アミド基がよく用いられており、硫黄原子に着目してみると単純な低級アルキルチオ基の導入例を除くと硫黄原子を含む置換基が用いられた例は極めて少ない。加えて低級アルキルチオ基の導入による抗菌力の向上、感染治療効果の向上に関する知見もない。また芳香族複素環7位側鎖への導入例は芳香族複素単環を1個導入する例(特開昭58-174386 号公報、特開平3-157387号公報)があるのみで連続する芳香族複素単環の導入例は過去の文献においても全く合成された例がなく開示はおろか示唆も全くされていない。
【0003】
近年、セファロスポリン側鎖にジヒドロキシフェニル誘導体及びN−ヒドロキシピリドン基を有するセファロスポリン類が開示された(特開昭59-93084号公報、同61-267587 号公報、同63-152386 号公報、特開平2-15089 号公報、同2-152982号公報)。これらセファロスポリン側鎖にジヒドロキシフェニル誘導体及びN−ヒドロキシピリドン基を有するセファロスポリン化合物は緑膿菌を含むグラム陰性菌には効果を示すが、ブドウ球菌を含むグラム陽性菌に対して抗菌力が弱く、一部の化合物では効果の見られないものもある。また緑膿菌においては試験管内抗菌力は優れているものの、マウス全身感染治療効果では試験管内抗菌力で見られた優れた効果が観察されず、これらの試験管内抗菌力と生体における感染治療効果の著しい差は臨床面での応用に大きな障害となっている。
【0004】
また先のセファロスポリン側鎖にジヒドロキシフェニル誘導体を有するセファロスポリン化合物はその化学構造上、カテコールアミン類と類似しているため、生体内でカテコールアミン様の作用つまり中枢系への作用が副作用として発現するという問題点を有している。加えて、その化学構造類似性からカテコール−O−メチルトランスフェラーゼ等、酵素の基質になり生体内で容易に代謝・不活化を受けることも判明しており、これらカテコールアミン類との化学構造の類似はヒト又は動物における感染症治療効果において有効性を発現しにくい原因と考えられる。
【0005】
以上、多数のセファロスポリン系抗菌剤が開示・報告されてきたが、これらの化合物の中でブドウ球菌を含むグラム陽性菌から緑膿菌を含むグラム陰性菌まで幅広く強力な抗菌作用及び感染症治療効果を有するものとなると皆無である。
【0006】
【発明が解決しようとする課題】
セファロスポリン系抗菌剤は細菌にのみ選択毒性を示し動物細胞に対しては影響を与えないことから副作用の少ない抗生物質として細菌による感染症の治療に広く使用され有用性の高い薬剤である。
【0007】
しかしながら、近年医療現場において臨床検査材料から検出される2大菌種はグラム陽性菌であるブドウ球菌、グラム陰性菌である緑膿菌であることが判明している。緑膿菌は免疫力の低下した患者から難活性感染症の起炎菌として高い頻度で分離され、また、ブドウ球菌には抗菌剤全般に耐性を示す黄色ブドウ球菌(MRSA)があり臨床上深刻な社会問題となっている。更に、これら両菌種による混合複雑感染も少なくない。
【0008】
このような状況からMRSA、ブドウ球菌を含むグラム陽性菌及び緑膿菌を含むグラム陰性菌に対しバランスがとれ、なおかつ強い抗菌力を示す抗菌剤が求められている。
【0009】
【課題を解決するための手段】
本発明者はブドウ球菌を含むグラム陽性菌から緑膿菌を含むグラム陰性菌まで幅広く優れた抗菌力及び感染症治療効果を示す新規なセファロスポリン誘導体を提供することを目的としセフェム骨格の7位に2−(2−アミノチアゾール−4−イル)−2−置換オキシイミノアセトアミド基又は2−(5−アミノ−1,2,4−チアジアゾール−3−イル)−2−置換オキシイミノアセトアミド基を有する新規なセファロスポリン誘導体について鋭意研究した。その結果、置換オキシイミノ部の置換基としてヘテロ環置換ヒドロキシピリドンを有する新規セファロスポリン化合物は合成例が全く無い新規化合物であり、更に本新規化合物はブドウ球菌を含むグラム陽性菌から緑膿菌を含むグラム陰性菌まで幅広く優れた抗菌力及び感染治療効果を示すという驚くべき事実を見出し本発明を完成した。
【0010】
即ち、過去の文献においてセフェム骨格の7位における2−(2−アミノチアゾール−4−イル)−2−置換オキシイミノアセトアミド基又は2−(5−アミノ−1,2,4−チアジアゾール−3−イル)−2−置換オキシイミノアセトアミド基の置換基には分子の大きいものの導入例はなく、また、連続する複数の芳香族複素単環の導入例は開示はおろか示唆も全くされていなかった。
【0011】
新規な7位置換基を有する本発明化合物は従来のセファロスポリン抗菌剤に比べブドウ球菌を含むグラム陽性菌から緑膿菌を含むグラム陰性菌まで幅広い抗菌力を示す上に、マウス全身感染治療効果においても著しい治療効果を示し医薬品としての有用性を示している。例えば、黄色ブドウ球菌を用いたマウス全身感染治療効果は抗MRSA用薬として用いられているフロモキセフとほぼ同等であり最近開発された第4世代セファロスポリン、セフピロームよりも優れている。
【0012】
一方、緑膿菌を用いたマウス全身感染治療効果はセフタチダイムでは無効であったものに対して著しく低い薬剤濃度で有効であることが明らかとなった。更にこれらの全身感染治療効果は7位側鎖部分に硫黄原子を導入することで更に増強されるという驚くべき事実も明らかとなった。
また、近年開示されたセファロスポリン側鎖にジヒドロキシフェニル誘導体及びN−ヒドロキシピリドン基を有するセファロスポリン化合物は緑膿菌を含むグラム陰性菌には効果を示すがブドウ球菌を含むグラム陽性菌に対して抗菌力が弱く、一部の化合物では治療効果の見られないものがあるが、本発明化合物はグラム陽性菌、グラム陰性菌のいずれに対しても抗菌力が優れているばかりでなく、マスウを用いた全身感染においても著しい治療効果を示している。
【0013】
更に本発明化合物はその化学構造がカテコールアミン類とは異なるため酵素(カテコール−O−メチルトランフェラーゼ)による代謝不活化を受けにくい上、カテコールアミン様の中枢作用を示さないことから、カテコールアミン類と化学構造上、類似している前述のジヒドロキシフェニル基を有するセファロスポリン化合物で問題となった代謝不活化されやすい中枢系副作用、更にアレルギー性副作用等の問題点が改善され、ヒト又は動物における感染症治療効果を高めることができた。
【0014】
以上の点で本発明化合物は公知化合物のいずれにも分類不可能な全く新規の化合物であり、本発明化合物の有する抗菌力及び感染治療効果は従来の技術からはうかがい知ることのできなかったものであり、ここに本発明によって開示されたことで明らかとなった。
【0015】
また、本発明の下記一般式[9]及び一般式[10]で表わされる一連の化合物は文献未記載の新規化合物であり、一般式[9]及び一般式[10]の化合物より導かれる下記一般式[8]の化合物は本発明化合物を含む広範囲なセファロスポリン化合物の重要な合成中間体となる。

[Industrial application fields]
The present invention relates to a novel cephem compound useful as an antibacterial agent, a pharmaceutically acceptable salt thereof, a method for producing the same, and an antibacterial agent containing these as active ingredients.
[0002]
[Prior art]
Various cephalosporin-based antibacterial agents have been synthesized in response to the transition of infection-causing bacteria in the medical field. Side chains that have been used in these cephalosporin-based antibacterial agents can be broadly divided into 3-position side chains and 7-position side chains. The 3-position side chains are aromatic quaternary ammonium and aromatic heterocycles via sulfur atoms. Alternatively, aromatic quaternary ammonium via a sulfur atom is often introduced. The 7-position side chain has a 2- (2-aminothiazol-4-yl) -2-substituted oxyiminoacetamido group or 2- (5-amino-1,2,4-thiadiazol-3-yl) -2- A substituted oxyiminoacetamide group is used, and a substituted lower alkyl group is often introduced into the substituted oxyimino moiety. A halogen atom, a carboxyl group, and an amide group are often used as the substituent on the substituted lower alkyl group. When attention is paid to the sulfur atom, a substituent containing a sulfur atom is excluded except for a simple introduction example of a lower alkylthio group. Very few examples have been used. In addition, there is no knowledge on the improvement of antibacterial activity and the effect of infection treatment by introduction of lower alkylthio groups. In addition, examples of introduction into the aromatic heterocyclic 7-side chain include only one example of introducing an aromatic heteromonocyclic ring (Japanese Patent Laid-Open Nos. 58-174386 and 3-157387). There have been no examples of the introduction of group heteromonocycles in the past literature, and no disclosure or suggestion has been made.
[0003]
Recently, cephalosporins having a dihydroxyphenyl derivative and an N-hydroxypyridone group in the side chain of cephalosporin have been disclosed (Japanese Patent Laid-Open Nos. 59-93084, 61-267587, and 63-152386). JP-A-2-15089 and JP-A-2-52982). These cephalosporin side chain dihydroxyphenyl derivatives and cephalosporin compounds having an N-hydroxypyridone group are effective against gram-negative bacteria including Pseudomonas aeruginosa, but have antibacterial activity against gram-positive bacteria including staphylococci. However, some compounds are not effective. In addition, although Pseudomonas aeruginosa has excellent antibacterial activity in vitro, the superior effects observed in antimicrobial activity in vitro were not observed in the effect of treating mouse systemic infection. The significant difference is a major obstacle to clinical application.
[0004]
In addition, the cephalosporin compound having a dihydroxyphenyl derivative on the side chain of cephalosporin is similar to catecholamines in terms of its chemical structure, and therefore, a catecholamine-like action in the living body, that is, an action on the central system, appears as a side effect. Have the problem of In addition, its chemical structure similarity has been found to be a substrate for enzymes such as catechol-O-methyltransferase and easily metabolized and inactivated in vivo. The similarity in chemical structure with these catecholamines This is considered to be a cause of difficulty in expressing effectiveness in the treatment of infectious diseases in humans or animals.
[0005]
As described above, a large number of cephalosporin antibacterial agents have been disclosed and reported. Among these compounds, a wide range of powerful antibacterial actions and infections from Gram-positive bacteria including staphylococci to Gram-negative bacteria including Pseudomonas aeruginosa. Nothing has a therapeutic effect.
[0006]
[Problems to be solved by the invention]
A cephalosporin antibacterial agent is a highly useful drug that is widely used in the treatment of bacterial infections as an antibiotic with few side effects because it exhibits selective toxicity only to bacteria and does not affect animal cells.
[0007]
However, in recent years, it has been found that the two major bacterial species detected from clinical test materials at medical sites are gram-positive bacteria, staphylococci, and gram-negative bacteria, Pseudomonas aeruginosa. Pseudomonas aeruginosa is frequently isolated as a pathogenic fungus of intractable infections from patients with reduced immunity, and Staphylococcus aureus has Staphylococcus aureus (MRSA) that is resistant to all antibacterial agents and is clinically serious. It has become a serious social problem. In addition, there are many mixed infections caused by both species.
[0008]
Under such circumstances, there is a demand for antibacterial agents that are balanced against MRSA, gram-positive bacteria including staphylococci, and gram-negative bacteria including Pseudomonas aeruginosa and exhibit strong antibacterial activity.
[0009]
[Means for Solving the Problems]
The present inventor aims to provide a novel cephalosporin derivative having a wide range of excellent antibacterial activity and infectious disease treatment effect from gram positive bacteria including staphylococci to gram negative bacteria including Pseudomonas aeruginosa. 2- (2-aminothiazol-4-yl) -2-substituted oxyiminoacetamido group or 2- (5-amino-1,2,4-thiadiazol-3-yl) -2-substituted oxyiminoacetamido group at the position We have intensively studied new cephalosporin derivatives having As a result, a novel cephalosporin compound having a heterocyclic-substituted hydroxypyridone as a substituent of the substituted oxyimino moiety is a novel compound with no synthesis examples, and this novel compound further eliminates Pseudomonas aeruginosa from Gram-positive bacteria including staphylococci. The present invention has been completed by finding the surprising fact that it exhibits a wide range of excellent antibacterial activity and infection treatment effects, including Gram-negative bacteria.
[0010]
That is, in the past literature, a 2- (2-aminothiazol-4-yl) -2-substituted oxyiminoacetamido group at the 7-position of the cephem skeleton or 2- (5-amino-1,2,4-thiadiazole-3- Yl) -2-Substituted oxyiminoacetamide groups have no examples of introduction of large molecules, and no examples of introduction of continuous aromatic heteromonocycles have been disclosed or suggested.
[0011]
The compound of the present invention having a novel 7-position substituent exhibits a broad antibacterial activity from gram-positive bacteria including staphylococci to gram-negative bacteria including Pseudomonas aeruginosa as compared with conventional cephalosporin antibacterial agents, In terms of effect, it shows a remarkable therapeutic effect, indicating its usefulness as a pharmaceutical product. For example, the therapeutic effect on systemic infection of mice using Staphylococcus aureus is almost the same as that of Flomoxef, which is used as an anti-MRSA drug, and is superior to the recently developed 4th generation cephalosporin and cefpirom.
[0012]
On the other hand, it was clarified that the therapeutic effect on systemic mouse infection using Pseudomonas aeruginosa was effective at a significantly lower drug concentration than that which was ineffective with ceftatidim. Furthermore, the surprising fact that these systemic infection treatment effects were further enhanced by introducing a sulfur atom into the 7-position side chain portion was also revealed.
In addition, recently disclosed cephalosporin compounds having a dihydroxyphenyl derivative and an N-hydroxypyridone group on the side chain of cephalosporin are effective against gram-negative bacteria including Pseudomonas aeruginosa, but against gram-positive bacteria including staphylococci. The antibacterial activity is weak against some compounds, and some compounds have no therapeutic effect, but the compounds of the present invention are not only excellent in antibacterial activity against both gram-positive and gram-negative bacteria, It also shows a significant therapeutic effect in systemic infections using trout.
[0013]
Furthermore, since the compound of the present invention has a chemical structure different from that of catecholamines, it is less susceptible to metabolic inactivation by an enzyme (catechol-O-methyltransferase) and does not exhibit a catecholamine-like central action. In addition, problems such as central side effects that are easily caused by metabolic inactivation, and allergic side effects that have been a problem with similar cephalosporin compounds having the above-mentioned dihydroxyphenyl group have been improved, and treatment of infectious diseases in humans or animals The effect could be enhanced.
[0014]
In view of the above, the compound of the present invention is a completely new compound that cannot be classified as any of the known compounds, and the antibacterial activity and infection treatment effect of the compound of the present invention could not be known from the prior art. And became clear by the disclosure of the present invention.
[0015]
In addition, a series of compounds represented by the following general formula [9] and general formula [10] of the present invention is a novel compound not described in the literature, and is derived from the compounds of general formula [9] and general formula [10] below. The compound of the general formula [8] is an important synthetic intermediate for a wide range of cephalosporin compounds including the compound of the present invention.
