Description

【0001】
【発明の属する技術分野】
本発明は、優れた抗真菌作用と高い安全性を有するアゾール誘導体又はその塩、その製造中間体、及びそれを有効成分として含有する医薬に関する。
【0002】
【従来の技術】
真菌症には、各種白癬、頑癬、乾癬、皮膚カンジダ症等に代表される表在性真菌症と、真菌性髄膜炎、真菌性呼吸器感染症、真菌血症、尿路真菌症等に代表される深在性真菌症とがある。このうちカンジダ症、アスペルギルス症等の深在性真菌症は、癌化学療法剤や免疫抑制剤の繁用、HIV感染等による生体内免疫の低下等により、特に近年増加の傾向にあり、これらの菌に有効な薬剤が望まれている。
【0003】
しかし、アスペルギルス菌及びカンジダ菌に有効な薬剤としては、従来、アムホテリシンBや、アゾール系化合物のフルコナゾール、イトラコナゾール等が知られているが、未だ僅少である。また、これらの薬剤は、いずれも安全性又は抗真菌作用の点で問題があり、アスペルギルス菌及びカンジダ菌に有効な抗真菌剤が望まれている。現在、より有効なアゾール系化合物の開発が行われており、例えば、2,2−ジフルオロ−2−アルキルチオメチル基、2,2−ジフルオロ−2−アルキルスルフィニルメチル基又は2,2−ジフルオロ−2−アルキルスルホニルメチル基を有するトリアゾール誘導体が知られているが(特許文献1〜3参照)、必ずしも十分に満足し得るものではない。

【0005】
【発明が解決しようとする課題】
従って、本発明は、安全性が高く深在性真菌症及び表在性真菌症に有効な抗真菌活性を有する新規アゾール誘導体を提供することを目的とする。
【0006】
【課題を解決するための手段】
斯かる実情において、本発明者らは、数多くのアゾール誘導体又はその塩を合成し、その抗真菌作用について鋭意検討を行った結果、下記一般式(1)で表される新規アゾール誘導体又はその塩が、深在性真菌症及び表在性真菌症の原因菌に対して優れた抗菌活性を示し、更にフルコナゾール耐性菌に対しても抗菌活性を示し、しかも毒性が低く、CYP(チトクロームP450)阻害作用が弱いという安全性も高いことを見出し、本発明を完成させた。
【0007】
すなわち、本発明は、下記一般式(1):
【0008】

Among these, deep-seated mycosis such as candidiasis and aspergillosis has tended to increase particularly in recent years due to the frequent use of cancer chemotherapeutic agents and immunosuppressive agents, and a decrease in in vivo immunity due to HIV infection and the like. A drug effective against bacteria is desired.
[0003]
However, as a drug effective against Aspergillus and Candida, amphotericin B and azole compounds such as fluconazole and itraconazole are conventionally known, but they are still scarce. In addition, these drugs have problems in safety or antifungal activity, and antifungal agents effective against Aspergillus and Candida have been desired. Currently, more effective azole compounds are being developed, for example, 2,2-difluoro-2-alkylthiomethyl group, 2,2-difluoro-2-alkylsulfinylmethyl group, or 2,2-difluoro-2. Triazole derivatives having an alkylsulfonylmethyl group are known (see Patent Documents 1 to 3), but are not always satisfactory.
