Benzenemethanol, 4-amino-3,5-dichloro-.alpha.-(1,1-dimethylethyl)aminomethyl- - Uses and synthesis methods
overview
Clenbuterol ((RS)-1-(4-amino-3,5-dichlorophenyl)-2-(tert-butylamino)ethanol) is a β2-adrenoceptor agonist. When entering the blood, clenbuterol stimulates adrenoceptors in the muscle, increasing the metabolism of carbohydrates and fats, and the metabolism and synthesis of proteins in the striated muscle. In addition to its known (and therapeutic) effects on the smooth muscles of the bronchial tree and blood vessels, clenbuterol can also increase the mass and strength of muscles.
Pharmacological Study
Gao Jingpeng et al. discussed the effect of clenbuterol on diaphragm cell apoptosis and expression of apoptosis-related protein Fas in chronic obstructive pulmonary disease (COPD) model rats. Methods: Male SPF grade W istar rats were randomly divided into three groups: A, B and C. Each group was further divided into subgroups of 4 weeks before modeling, 2 weeks after modeling and 4 weeks after modeling. Group A was fed normally. Group B and C were modeled by tracheal injection of lipopolysaccharide (LPS) and smoking. Group C was given clenbuterol intervention on the basis of modeling. The apoptosis rate and Fas expression rate of diaphragmatic cells in each group were detected by phosphodeoxyuracil nick end labeling and immunohistochemistry. Results: After 4 weeks, the model of group B and C was successfully established by HE section of lung. With the passage of time, there was no statistical difference in the positive rate of apoptosis and Fas expression among subgroups in group a. the two-week and four-week subgroups in group B and group c were significantly higher than those in group a at the same time (p <0.01), and there was no statistical difference between subgroups in group B and group c. The positive rate of apoptosis in subgroups of group c at 2 weeks and 4 weeks was significantly lower than that in group B at the same time (P<0.05). Conclusion: Smoke and LPS participate in the regulation of diaphragm cell apoptosis during the formation of COPD. Clenbuterol may reduce diaphragm cell apoptosis by inhibiting oxidative stress and down-regulating Fas expression, and has certain therapeutic effect on diaphragm fatigue caused by COPD.
Clenbuterol
Clenbuterol, also known as clenbuterol, is a β-adrenergic agonist (β-stimulant for short), which is commonly used in medicine to treat asthma. It has the effect of promoting animal growth, reducing fat content, and increasing lean meat percentage, so it is often used as a feed additive, commonly known as clenbuterol. It will form residues in animal tissues. People can cause poisoning after eating pork containing clenbuterol, usually with muscle tremor, heart palpitations, mental tension, nausea, dizziness and other symptoms. Our government banned clenbuterol hydrochloride as a feed additive in 1997.
Production method
It is obtained by reduction, chlorination, bromination of p-nitroacetophenone, condensation with tert-butylamine, and reduction with potassium borohydride. The hydrochloride of this product is after salt is formed.
