1-Cyclopropyl-7- [ (S, S) -2,8-diazabicyclo [4.3.0] non-8-yl] -6-fluoro-8-methoxy-1,4-dihydro-4-oxo-3-quinolinocarboxylic acid hydrochloride, which is the name of the chemical substance. It is quite crucial in the field of medicine and often appears as an antibacterial drug.

However, this drug also has many side effects. The first one to bear the brunt is the impact on the gastrointestinal tract. Patients who take it often experience nausea, vomiting, abdominal pain, diarrhea, etc. This is because the drug stimulates the gastrointestinal mucosa, causing gastrointestinal dysfunction. For example, the "Shennong Materia Medica Classic" says: "Although the drug cures the disease, it also hurts the health." This is also called also.

Secondly, the nervous system is also affected. After taking the drug, some patients may feel dizzy, headache, insomnia, and even convulsions and convulsions. Because the drug affects the transmission of neurotransmitters and the excitability of nerve cells. As the ancient doctor said: "The brain is the sea of medulla, and the sex of medicine is fierce, and it is easy to disturb it." The effect of this drug on the brain is exactly what he said.

Furthermore, it also has adverse effects on skeletal muscles. Especially in children and adolescents, the use of this medicine may affect bone development, resulting in joint pain and muscle weakness. The Yellow Emperor's Nei Jing says: "The kidney dominates the bone and produces marrow." The drug affects the bone or is related to the function of the kidney.

In addition, it can also cause allergic reactions. In mild cases, skin rash, itching, and in severe cases, anaphylactic shock, which endangers life. This is due to the individual's different sensitivity to the drug, causing the immune system to overreact. Ancient medical records also contain that the disease of drug allergy is changeable and cannot be prevented.

To sum up, although this medicine has antibacterial effects, it should not be underestimated for side effects. Doctors should weigh the pros and cons and handle it cautiously to ensure the well-being of patients.

1-Cyclopropyl-7- [ (S, S) -2,8-diazabicyclo [4.3.0] non-8-yl] -6-fluoro-8-methoxy-1,4-dihydro-4-oxo-3-quinoline carboxylic acid hydrochloride, which is a fine chemical substance, its preparation process is complicated and elegant.

The first is the choice of raw materials, and starting materials with specific purity and quality need to be prepared, such as cyclopropyl-related derivatives, nitrogen-containing dicyclic compounds, fluorinated and methoxy-substituted quinoline raw materials, etc., which are the basis for synthesis. If the raw materials are not pure, the synthesis road will be full of thorns, and the product will not reach the required quality.

The process of synthesis depends mostly on the wonderful method of organic synthesis. First, use appropriate reaction conditions to make cyclopropyl and quinoline skeletons cleverly connected, or use nucleophilic substitution, condensation, etc. This requires precise temperature control and time control. If the temperature is high, the side reactions will be plentiful, if the temperature is low, the reaction will be slow, and if the time is short, the reaction will not be completed, and the time will be < Br >
In addition, the introduction of dicyclic nitrogen structure requires the selection of specific catalysts and solvents to promote the reaction to the expected direction. The activity and selectivity of the catalyst depend on the configuration and yield of the product. The nature of the solvent also affects the reaction rate and product purity.

The introduction of fluorine and methoxy groups also requires exquisite design. For the introduction of fluorine, fluorine-containing reagents are often selected, and the timing and conditions are selected according to their reactivity. The addition of methoxy groups or the etherification reaction is used to ensure the precise position.

After the key structure is constructed, a salt-forming reaction is carried out to obtain hydrochloride. In this step, the amount of hydrochloric acid and the reaction environment need to be controlled to make the salt formation complete and the product pure. After

synthesis, it must go through the refining process. Recrystallization, chromatographic separation and other methods are used to remove impurities and improve purity. During recrystallization, the choice of solvent is most important, which is related to the crystalline morphology and purity of the product. Chromatographic separation requires adjusting parameters to achieve the best separation effect.

Every step requires rigorous operation and accurate detection to obtain high-quality 1-cyclopropyl-7- [ (S, S) -2,8-diazabicyclo [4.3.0] Non- 8-yl] -6-fluoro-8-methoxy-1,4-dihydro-4-oxo-3-quinoline carboxylic acid hydrochloride, which is a high-quality raw material for the pharmaceutical, chemical and other industries.
