Levamisole Hydrochloride, an alcohol molecule with the formula C11H13ClN2S, is an antihelminth drug widely used in animals and humans. The compound mainly works by inhibiting the nervous system activity of the worms, thereby causing the death of the worms. In addition, Levamisole Hydrochloride also has a certain immune system regulation effect, which can enhance the immune function of the body and is helpful for the treatment of certain immune diseases. The melting point is 227°C-233°C, the boiling point is 407.7°C, and the specific gravity is 1.25. Its physical properties and solubility properties are affected by ambient temperature and pH. It is easy to absorb water and decompose quickly in a humid environment, and loses its efficacy. It should be stored in a cool and dry place.
Levamisole Hydrochloride is a white crystalline powder commonly used in veterinary and medical fields. Here are all the uses for Levamisole Hydrochloride:
1. Veterinary use:
Levamisole Hydrochloride is a broad-spectrum anti-helminth drug indicated for the treatment of various helminth infections in livestock and poultry. It is mainly used for intestinal helminth infection of horses, intestinal helminth infection of cattle and sheep, small animals such as dog and cat helminth infection, and poultry lung helminth infection. The amount of Levamisole Hydrochloride used in veterinary medicine is determined by the weight of the animal and the condition of the worm infestation.
2. Human medical use:
Levamisole Hydrochloride is also used to treat helminth infections in humans, which are usually caused by parasites. Some common helminth infections include intestinal worms, mucosal nematodes, hookworms, and roundworms. Levamisole Hydrochloride can prevent the growth of parasites, but also strengthen the body's immune system and increase the body's resistance to parasites.
3. Immunomodulation purposes:
Levamisole Hydrochloride is also used to boost immunity and train the body to fight off some diseases and infections. It has been shown to increase the number of T cells and enhance their ability to recognize and eliminate viruses and bacteria. Levamisole Hydrochloride can also promote the activity of white blood cells, thereby inhibiting malignant tumors.
4. Detoxification effect:
Levamisole Hydrochloride can be combined with some toxins to slow down the harmful effects on the human body. Specifically, it slows down the effects of drugs (such as cocaine, fentanyl, etc.), thereby relieving harm to the body and brain. However, this use has diminished because Levamisole Hydrochloride itself has certain side effects.
5. Other uses:
Levamisole Hydrochloride has many other uses. For example, it can be used to treat autoimmune diseases such as angular cheilitis and rheumatoid disease, and it has been proven to improve liver cirrhosis. In addition, Levamisole Hydrochloride is often used in the treatment of different types of tumors.
Reactive properties of Levamisole Hydrochloride:
(1) The acid-base properties of Levamisole Hydrochloride:
Levamisole Hydrochloride is a nitrogen heterocyclic ring with very characteristic absorption spectrum. It will undergo partial protonation reaction under acidic conditions to form several soluble salts. For example, in mild acid solution, Levamisole Hydrochloride can react with bicarbonate to form a soluble carbonate salt.
(2) Thermal decomposition reaction of Levamisole Hydrochloride:
Levamisole Hydrochloride decomposes at high temperatures to produce a mixture of diethylaminomethane sulfinate and flammable gases. Therefore, you need to pay attention to safety during the heating process.
(3) Reduction reaction of Levamisole Hydrochloride:
Some reducing agents can reduce Levamisole Hydrochloride to 1,2,3,4-tetrahydroheteroimidazole with simultaneous release of hydrogen sulfide, for example, metal anions with sulfoxide ligands (such as Pd(OAc)2/NaBH4) and nickel (Ni/C), also optionally based on a co-catalyzed reduction reaction.
(4) Chlorination reaction of Levamisole Hydrochloride:
Levamisole Hydrochloride can be chlorinated under alkaline conditions to form N-ethyl-2-(2,3-dichloropropyl)-4-methyl-1,2,3,4-tetrazolidinedi Hydrochloride. This product can be used as a substitute for Levamisole Hydrochloride for some biological research.
(5) Oxidation reaction of Levamisole Hydrochloride:
Levamisole Hydrochloride can be oxidized by certain oxidizing agents such as chlorine and hydrogen peroxide to produce oxidation products. Under the action of chlorine, Levamisole Hydrochloride can produce sulfuric acid diethylaminomethane and sulfur chloride diethylaminomethane and other products. Under the action of hydrogen peroxide, Levamisole Hydrochloride can undergo an oxidation reaction to form amino acids such as cysteine and methylcysteine.
pH and Solubility:
Levamisole Hydrochloride is an organic compound with a relatively stable pH, and its aqueous solution is weakly acidic. When reacted with hydrochloric acid, Levamisole Hydrochloride forms a more hydrophilic hydrochloride form.
Because the molecular structure of Levamisole Hydrochloride has a certain polarity, it can have better solubility with water and some other hydrophilic solvents. At room temperature, the water solubility of Levamisole Hydrochloride is 5.47 g/100 mL, the solubility will increase under acidic conditions, and the solubility will decrease under alkaline conditions.
Optical properties:
