Abstract
本发明涉及新型的如式(I)所示的2-羟基喹啉
类化合物及其它们的旋光异构体和可药用的盐类。
式中对A,R1到R8和X的定义参见说明书。
Description
本发明涉及具有广抗菌谱的新型2-羟基喹啉类化合物及其旋光异构体和盐类。
本发明还涉及这些2-羟基喹啉的制备方法。
商业用的2-羟基喹啉抗菌剂的典型代表包括:enoxacin(依诺沙星),norfloxacin(诺氟沙星),ofloxacin,ciprofloxacin,和tosufloxacin。然而,人们逐渐发现这些抗菌的2-羟基喹啉遇到革兰氏阳性细菌时抗菌活性相对较低,而且常用抗2-羟基喹啉的菌株被报道。
因此,开发具有广抗菌谱的2-羟基喹啉抗菌药物是必要的。
下面详细解释本发明。
本发明的一个目的是提供式(Ⅰ)表述的新型2-羟基喹啉类的化合物及其旋光异构体和盐类的结构式
式中(Ⅰ)中A表示氮或者
;Y表示氢、卤素、较低级的烷基或烷氧基,Y也可以与R1一起形成-CH2CH2CH2-,-CH2CH2CH(CH3)-,-OCH2CH2-,-OCH2CH(CH3)-,-SCH2CH2-或-SCH2CH(CH3)-结构;R1如上规定,也可表示为含1至3个碳原子的直链或环状低级烷基,此烷基可被一个卤素原子或一个苯基所取代,而苯基也可被一个或两个卤素原子所取代。
R2和R3可以相同,也可以不同,单独表示氢、硝基、甲酯基(CH3OOC-)和乙酯基(C2H5OOC-)。
R4表示氢、低级烷基、低级烷氧基或者是一个氨基保护基团。
R5、R6、R7和R8可相同也可不同,单独表示氢、低级烷基,并可被氨基、羟基或卤素任意取代。
X表示氢、卤素、氨基或低级烷基。
