Description
本發明提供新穎苯丙醇類(phenicol)衍生物、其於哺乳動物中治療感染之用途、包含該等新穎化合物之醫藥組合物、及製備該等化合物之方法。
針對用於治療動物中細菌感染之新穎抗生素有增長性的需求,及尤其需求可克服細菌對現有抗生素抗性之日益增加的新穎藥劑。
氟苯尼考(Florfenicol)為寬廣範圍之僅用於獸用藥品中之苯丙醇類抗生素。苯丙醇類抗生素類別為細菌蛋白質生物合成之有效抑制劑。氟苯尼考具有寬廣範圍之對抗許多格蘭氏陰性(gram-negative)及格蘭氏陽性細菌之活性,及適用於預防及治療鳥類、爬蟲類、魚、貝類及哺乳動物中因易罹患病原體所致之細菌感染。氟苯尼考的一種重要用途是在牛中治療諸如彼等因例如溶血曼哈米亞桿菌(Mannheimia haemolytica
)、多殺性巴氏桿菌(Pasteurella multocida
)及睡眠嗜血桿菌(Haemophilus somnus
)所致者之呼吸道感染。牛呼吸道疾病(BRD)之有效治療在降低另外為全球乳製品及牛肉工業經濟損失之首要原因之一者方面扮演重要角色。
在近年來報告指明細菌發展出對氟苯尼考之抗性及已跨諸如沙門氏菌(Salmonella
)(Bolton,L.F.等人,Clin.Microbiol.,1999,37,1348)、大腸桿菌(E.coli
)(Keyes,K.等人,Antimicrob.Agents
Chemother.,2000,44,421)、肺炎克雷伯氏桿菌(Klebsiella pneumonia
)(Cloeckaert,A.等人,Antimicrob.Agents Chemother.,2001,45,2381)之多個細菌屬種、及在水產病原菌、美人魚發光桿菌殺魚亞種(Photobacterium damselae subsp.Piscicida
)(先前技術中稱為殺魚巴氏桿菌(Pasteurella piscicida
))(Kim,E.等人,Microbiol.Immunol.,1996,40,665)中觀察到。根據日益增加之氟苯尼考抗性及具跨細菌種類及動物宿主抗性之基因之表觀遷移率之威脅(Cloeckaert,A.等人,Antimicrob.Agents Chemother.,2000,44,2858),具重要意義地需要維持或超越氟苯尼考之活性、同時亦可克服氟苯尼考抗性之挑戰之新穎抗生素。本發明之化合物代表此一改善。
