Sermorelin acetate is a white to grayish white crystalline powder, odorless and odorless. The molecular formula is C12H15NO3, CAS 86168-78-7, also known as 4- (4-hydroxyphenyl) -2-ethylamino-1-butanol ester, and its chemical structure is similar to that of phenylethanolamine neurotransmitters. It is soluble in methanol, ethanol, acetone, ethyl acetate, chloroform, methyl ethyl ketone, and benzene, as well as in water, but its solubility in water is relatively low. The oxygen atom in the acetic acid Shemerelin molecule can be replaced by various functional groups, thus various chemical reactions can occur. It is a synthetic steroid hormone that can be used for hormone replacement therapy. It has a structure and function similar to natural androgens and can be used to treat hormone deficient diseases such as male hypogonadism and female menopausal syndrome. By replacing the hormones lacking in the patient's body, Shemerelin acetate can help improve the symptoms of these conditions and improve the patient's quality of life.

The structural description of Shemerelin acetate is as follows:
Shemerelin acetate is a steroid hormone with a chemical structure similar to natural androgens. It is a white or almost white crystalline powder, odorless, tasteless, and less soluble in organic solvents, but almost insoluble in water. The molecular formula of Shemerelin acetate is C24H30O5, with a relative molecular weight of 406.49. The chemical structure formula is as follows:
Among them, the skeleton of Shemerelin acetate is the same as the basic skeleton of natural androgens, both based on cholesterol derivatives. In terms of structure, the main difference between Shemerelin acetate and natural androgens lies in the differences in side chains and substituents.
The side chains of Shemerelin acetate are isopropyl and isopentyl, with isopropyl and isopentyl composed of 9 carbon atoms, respectively. The length and composition of the side chains are similar to those of natural androgens, but the positions and configurations of isopropyl and isopentyl groups are different from those of natural androgens. This different side chain structure distinguishes Shemerelin acetate from natural androgens in terms of chemical properties and biological activity.
In addition, the substituents of Shemerelin acetate are also different from natural androgens. In natural androgens, there is usually a hydroxyl or ketone group on the 10th carbon atom, while in Shemerelin acetate, there is a carboxyl group on the 10th carbon atom, which forms an ester bond with acetic acid. This different substituent structure results in differences in chemical properties and stability between Shemerelin acetate and natural androgens.
The structural characteristic of Shemerelin acetate is that it has a specific side chain and substituent structure based on the steroid skeleton. This structural characteristic makes Shemerelin acetate different from natural androgens in terms of chemical properties and biological activity, and has a certain therapeutic effect.
The preparation of Shemerelin acetate mainly involves the reaction of diethyl terephthalate and ammonia to generate Shemerelin acetate, which is then obtained through the esterification reaction of acetic anhydride. The specific experimental steps are as follows:
1. Add diethyl phthalate and ammonia to the beaker and stir evenly.
O=C (OC2H5) C6H4COOH + NH3 → HOSi (OC2H5) 2NH4OH (approximately 88%)
2. Heat the beaker in a water bath to 80 ℃ and hold for 2 hours.
HOSi(OC2H5)2NH4OH → HOSi (OC2H5)2NH3OH
3. Cool the reaction solution to room temperature.
4. Add acetic anhydride to the reaction solution and reheat it to 80 ℃ for 2 hours.
HOCH2CH2NH3OH+CH3COOC2H5 → HOCH2CH2NHCOOCCH3+CH3COOH
5. After the reaction is completed, cool the reaction solution to room temperature.
6. Add a certain amount of sodium chloride, stir thoroughly and let stand for about 10 hours.
7. Collect sediment by separating the solution.
8. Wash the precipitate with ethanol to remove sodium acetate and unreacted acetic anhydride.
9. Finally, the precipitate was dried to obtain Shemerelin acetate.
The laboratory synthesis method of Shemerelin acetate usually includes the following steps:
1: Reaction of Benzenesulfonyl Methanol and Calcium Chloride
Mix benzenesulfonyl methanol and calcium chloride in an anhydrous organic solvent. The purpose of this step is to undergo a hydrogen bond exchange reaction between benzenesulfonyl methanol and calcium chloride, resulting in the formation of chlorophenyl carbamate. The chemical equation for this reaction can be expressed as:
C6H5SO2CH2OH+CaCl2 → C6H5SO2CH2O-CaCl
This reaction requires strict anhydrous conditions, as the presence of water can interfere with the formation of hydrogen bonds. Commonly used anhydrous organic solvents include ether, acetone, or tetrahydrofuran. This step of the reaction may require mild conditions in order for the reaction to proceed better.
2: Epoxidation Reaction of Amino Hydrocarbons and Chlorophenyl Carbamate
In an anhydrous organic solvent, mix the amino hydrocarbon with the chlorinated phenyl carbamate generated in the previous step, and add an appropriate amount of organic oxidant such as peroxide. The purpose of this step is to undergo an epoxidation reaction between amino hydrocarbons and chlorinated phenylcarbamates, resulting in the epoxidized Shemerelin compound. The chemical equation for this reaction can be expressed as:
C6H5SO2CH2O-CaCl+R3N-H → C6H5SO2CH2O-CaCl+R3N-O
Among them, R3N-H represents amino hydrocarbons, and R3N-O represents epoxidized Shemerelin compounds.
3: Decalcification reaction and acidification
Under acidic conditions, the calcium ions in the compound generated in the previous step are removed to produce shermorillin ethyl ester. Then mix the ethyl ester of Shemerelin with a dilute hydrochloric acid solution to hydrolyze it to produce Shemerelin acetate. The chemical equation for this process can be expressed as:
C6H5SO2CH2O-CaCl+H+→ C6H5SO2CH2OH+Ca2+
C6H5SO2CH2OH+H+→ C6H5SO2CH2O-H+
C6H5SO2CH2O-H++H2O → C6H5SO2CH2OH+H3O+
Among them, C6H5SO2CH2OH represents shermorilin ethyl ester, and H3O+represents hydrogen ions.
The above are the main steps and chemical equations of the laboratory synthesis method for Shemerelin acetate. It should be noted that there may be differences in actual operation due to specific experimental conditions and reagents. For specific synthesis experiments, it is recommended to make appropriate adjustments based on the specific situation of the experiment.
