Paragraph 0031-0033, (2021/09/21)
The invention discloses a fluoroquinolone derivative which is characterized in that the fluoroquinolone derivative has a structure as shown in a general formula (I) or an isomer thereof or a pharmaceutically acceptable salt thereof or a mixture of the structures. Wherein R1 is selected from C1-C4 alkyl groups; or R1 is selected from a spiro or bridged alkane chain which shares one or two carbon atoms with pyrrolidinyl connected with R1, and R1 contains 1-6 carbon atoms; O atom on the benzene ring is alternatively connected with R2 or R3: when the O atom on the benzene ring is connected with R2, R2 is selected from substituted or unsubstituted C2-C4 alkylene, and R3 does not exist; when O atom is connected with R3, R2 is selected from C3-C6 cycloalkyl, and R3 is selected from C1-C3 alkyl. The fluoroquinolone derivative provided by the invention has a good inhibition effect on escherichia coli, staphylococcus aureus and tetracoccus, and provides a certain reference for further design of quinolone compound structures.
