There is a need for a new antibiotic having a novel mechanism of action, which exhibits strong antibacterial activity not only against sensitive bacteria, but also against resistant bacteria thereof, and at the same time possess excellent solubility and safety profile amenable to human use. As a result of intensive research, the present inventors have found that N-phosphonoxymethyl prodrugs of hydroxyalkyl thiadiazole derivatives represented by general formula (I), a regioisomer, a stereoisomer, or a pharmaceutically acceptable salt thereof possess excellent solubility and safety profile for use in human for the treatment of bacterial infectious diseases.
需要一种具有新型作用机制的新抗生素,不仅对敏感细菌表现出强大的抗菌活性,而且对抗药性细菌也具有同样的作用,并且同时具有出色的溶解性和安全性,适合人类使用。经过密集研究,现有发明者发现,由一般式(I)所代表的羟基烷基噻二唑衍生物的N-磷酸甲氧甲基前药,其构象异构体、立体异构体或其药学上可接受的盐具有出色的溶解性和安全性,可用于治疗人类的细菌感染性疾病。
