The main body is quinoline-3-carboxylic acid, which is the core structure. Quinoline is a nitrogen-containing heterocyclic aromatic hydrocarbon with a carboxyl group attached at the 3rd position.
Looking at the substituent again, the 1-position is a cyclopropyl group, which is connected by a single bond. The 6-position has a fluorine atom, and the 8-position has a methoxy group.
is particularly critical, and the 7-position connection (2,8-diazabicyclo [4.3.0] non-8-group). This bicyclic structure consists of two nitrogen atoms spaced in the bicyclic system. The bicyclic structure is [4.3.0], indicating that one ring contains 4 atoms, the other ring contains 3 atoms, the two rings share 0 atoms (non-bridged atoms), and the 8-position nitrogen atom is connected to the 7-position quinoline. < Br >
There are also (1 'S, 6' S) configuration labels, which are stereochemical information, indicating that the configuration of the 1-position and 6-position carbon atoms is determined according to the relevant stereochemical rules, so that the specific arrangement of molecules in space has a significant impact on their chemical, physical and biological activities. In short, the structure of this compound is complex, and the interaction between each group and the stereo configuration jointly determines its unique properties.

It is often a key component of antibacterial drugs. The principle of antibacterial observation is that it can produce topoisomerase IV and DNA rotatase of bacteria, both of which are central to DNA replication, transcription and repair in bacteria. This product has both of these, the DNA metabolism of bacteria is chaotic, the growth and reproduction are also suppressed, and eventually death.
Because of this ability, it is widely used in clinical practice. Such as respiratory tract infections, whether pneumonia, bronchitis, etc., have curative effect. Because of the growth of bacteria here, this product can be removed. In addition, it can also play work in urinary system infections, cystitis, pyelonephritis, etc. This is because bacteria often invade this domain, this product can be inhibited. In the case of intestinal infections, such as enteritis, dysentery, etc., it is also good to use and can solve the suffering of patients.
And this product has a wide antibacterial spectrum and is effective on Gram-positive and negative bacteria. Gram-positive bacteria such as Streptococcus pneumoniae, and negative bacteria such as Escherichia coli are all controlled by it. Therefore, diseases caused by a variety of bacteria can be used by doctors to treat patients' diseases and save them from pain.

This compound has a unique structure and its synthesis is quite challenging.
In the past, the synthesis of such compounds followed the classical organic synthesis path. The choice of starting materials is often a matter of success or failure. Or select aromatic hydrocarbons with specific functional groups, and introduce halogen atoms through halogenation reaction to lay the foundation for subsequent reactions. If a suitably substituted quinoline derivative is used as the starting material, under specific conditions, it undergoes a nucleophilic substitution reaction with halogenated cyclopropane, and a cyclopropyl group can be introduced.
It is especially crucial to construct a 7-position 2,8-diazabicyclo [4.3.0] non-8-based structure. Or it is achieved through a multi-step cyclization reaction. First, the intermediate containing nitrogen heterocyclic ring is prepared, and the reaction between amine and halogenated hydrocarbons is used to form a carbon-nitrogen bond. After intramolecular cyclization, the double-ring structure is formed. This process requires fine regulation of reaction conditions, such as temperature, solvent, catalyst, etc.
As for the introduction of 6-position fluorine atoms and 8-position methoxy groups, attention is also paid to. Fluorine atoms can be introduced by nucleophilic fluorination reaction, and methoxy groups can be formed by the reaction of corresponding phenolic compounds with halomethane under alkali catalysis. Finally, the 4-oxo structure is constructed through oxidation reaction, and then the target product can be obtained after appropriate post-treatment. However, the synthesis path needs to be repeatedly optimized to achieve high efficiency and high selectivity.
