Third, in terms of clinical treatment, this compound may provide new treatment options for some complex infections with poor efficacy of conventional antibacterial drugs. Doctors can carefully evaluate the specific condition of the patient and apply it to clinical treatment, bringing new hope for the patient's recovery.

What is the pharmacological mechanism of (3S) -10- (1-aminocyclopropyl) -9-fluoro-3-methyl-7-oxo-2, 3-dihydro-7H- [1,4] oxazino [2,3,4-ij] quinoline-6-carboxylic acid methanesulfonate?

(3S) -10- (1-aminocyclopropyl) -9-fluoro-3-methyl-7-oxo-2,3-dihydro-7H - [1,4] oxazino [2,3,4-ij] quinoline-6-carboxylic acid methanesulfonate, this is a compound with a unique structure. Its pharmacological mechanism is profound and complex, just like the journey of ancient medicine to explore the mysteries of life.

From the perspective of antibacterial mechanism, it is like a wise doctor's precise application of medicine, directly hitting the key points of pathogens. This drug can specifically act on the topoisomerase IV and DNA rotatase of bacteria, which are like key players in the key life processes of bacterial DNA replication, transcription and repair. The drug is tightly bound to it, like a strong shackle that binds its action, making the bacterial DNA double-strand broken and unable to repair and reconnect normally. In this way, the transmission of bacterial genetic information is blocked by boulders, and the replication process is abruptly stopped, just like a boat meeting a reef halfway through and cannot move forward. Bacterial proliferation is blocked, just like a new shoot is broken, making it difficult to grow into a lush state, eventually leading to bacterial growth inhibition and apoptosis.

Furthermore, this drug can also affect the function of bacterial cell membranes. Like a craftsman who repairs damaged city walls, it can change the permeability of cell membranes, causing loopholes in the original tight membrane barrier. Important substances in bacteria, such as nucleotides, amino acids, etc., are constantly seeping out from the leakage screen. The intracellular environment is disordered, the metabolic balance of bacteria is destroyed by external forces like a delicate balance, and many metabolic reactions cannot be carried out in sequence, just like the dislocation of the ancient clock and gears in an orderly operation, which makes it difficult to maintain bacterial life activities and gradually decays. In this way, (3S) -10- (1-aminocyclopropyl) -9-fluoro-3-methyl-7-oxo-2,3-dihydro-7H - [1,4] oxazino [2,3,4-ij] quinoline-6-carboxylic acid methanesulfonate plays an antibacterial effect and protects life and health with its unique pharmacological mechanism.

Its common unsafe reactions are in the gastrointestinal domain, or cause nausea, vomiting, abdominal pain, diarrhea. This is because the drug stimulates the gastrointestinal mucosa and disturbs the normal operation and transformation of the gastrointestinal tract. In the boundary of the central nervous system, or causes dizziness, headache, insomnia, because the drug affects the transmission and regulation of neurotransmitters. Furthermore, on the surface of the skin, or in the form of rash or itching, this is due to the body's allergic reaction to the drug.

When taking medication, if there is any of the above reactions, it must be treated with caution. Minor symptoms may be temporarily observed, but if the symptoms are severe or persistent, seek medical attention as soon as possible. Doctors can adjust the dosage of the drug according to the specific condition, or the category of the drug, to ensure safety and efficacy. In short, during the medication period, patients should pay careful attention to their own changes, communicate with the doctor frequently, and take care of their health together.

What is the synthesis method of (3S) -10- (1-aminocyclopropyl) -9-fluoro-3-methyl-7-oxo-2, 3-dihydro-7H- [1,4] oxazino [2,3,4-ij] quinoline-6-carboxylic acid methanesulfonate

At the beginning, a specific quinoline derivative is often used as the base. First, its specific positions, such as 6-position, 9-position, etc. are functionalized. The introduction of fluorine atoms at the 9-position can be achieved efficiently and accurately under suitable reaction conditions, such as the presence of specific temperatures, solvents and catalysts, with the help of suitable fluorination reagents.

The introduction of methyl groups at the 3-position also requires fine regulation. Or choose appropriate methylating reagents, and choose the best reaction path according to the activity of the reaction substrate and the reaction environment to ensure that methyl is accurately integrated at the 3-position.

The most critical one is the introduction of 10-position (1-aminocyclopropyl). In this step, a suitable cyclopropyl-containing intermediate must be prepared or obtained by cyclopropylation reaction. Then, through ingenious reaction strategies, ammonia cyclopropyl is connected to the quinoline matrix. This process involves various reaction mechanisms such as nucleophilic substitution and condensation, and requires strict control of reaction conditions, such as the ratio of reactants, reaction time, pH, etc.

As for the final formation of methanesulfonate, after synthesizing the carboxylic acid, it can be reacted with methanesulfonate in a suitable solvent in a certain proportion, and through the salt formation process, the target product (3S) -10- (1-aminocyclopropyl) -9-fluoro-3-methyl-7-oxo-2,3-dihydro-7H - [1,4] oxazino [2,3,4-ij] quinoline-6-carboxylic acid methanesulfonate.
