To develop an antibiotic having a novel mechanism of action, the present inventors have searched for a compound that has weak cytotoxicity, the physical property of high solubility in water, the effect of inhibiting both DNA gyrase GyrB and topoisomerase IV ParE subunits, and sufficient antibacterial activity. As a result, the present inventors have completed the present invention by finding that a compound of the present invention represented by the general formula (1), a pharmacologically acceptable salt thereof, and a prodrug thereof have desirable properties. The present invention provides a pharmaceutical composition (particularly, a preventive or therapeutic composition for infectious disease) comprising a compound represented by the formula (1), a pharmacologically acceptable salt thereof, or a prodrug thereof as an active ingredient.
为了开发一种具有新颖作用机制的抗生素,本发明人寻找具有以下特征的化合物:细胞毒性较弱,水溶性较高,能够抑制DNA酶旋转酶GyrB和拓扑异构酶IV ParE亚基,且具有足够的抗菌活性。结果,本发明人通过发现本发明的一种化合物(通式(1)所表示的化合物)、其药学上可接受的盐和前药具有理想的特性,从而完成了本发明。本发明提供了一种药物组合物(特别是用于预防或治疗传染病的组合物),该组合物包括通式(1)所表示的化合物、其药学上可接受的盐或前药作为活性成分。
