For antibacterial chlorine oxygen kui derivatives

The invention relates to an oxo-quinoline derivative with activity of resisting bacterial infection relevant diseases such as helicobacter pylori (Hp) infection disease. The invention specifically relates to a compound as shown in formula I in the specification, and a pharmaceutically acceptable salt, solvate or prodrug thereof, wherein R is selected from hydrogen, -C alkyl, -C alkenyl, -C alkynyl, or -C alkyl-phenyl, and the alkyl, alkenyl, alkynyl and phenyl can be randomly substituted by halogen, nitro, cyan, hydroxyl, -C alkoxy and phenyl; R is selected from hydrogen, -CONHR and -COOR, R and R are independently selected from -C alkyl and -C alkyl amino, and the amino is randomly substituted by one to two -C alkyls; R is selected from halogen, -C alkoxy, morpholinyl or piperazinyl.
