This drug has significant effect on liver and gallbladder diseases. First, it can help bile secretion, make bile flow unimpeded, and in cholestasis, such as primary cholangitis, it can relieve its symptoms and reduce the suffering of patients. Second, it has cholesterol-promoting power, which can reduce the saturation of cholesterol in bile, prevent the formation of cholesterol stones, and if there are stones, it can also promote their dissolution and make the stones gradually disappear. Third, in liver inflammation, it can protect liver cells, reduce the level of transaminase, and restore the normal function of the liver, such as non-alcoholic fatty liver disease. Fourth, it has the ability of immune regulation, which can adjust the body's immune response, and can slow down immune damage in autoimmune liver disease.
Therefore, 2% {[ (3α, 5β, 6β, 7β, 8 🥰, 9 🥰, 14 🥰) -3,6,7-trihydroxy-24-oxidized cholesterol-24-yl] ethyl ursodeoxycholic acid is of great significance in the prevention and treatment of hepatobiliary diseases. It is also a good medicine commonly used by doctors.

This is 2- {[ (3α, 5β, 6β, 7β, 8β, 9β, 14β) -3,6,7-trihydroxy-24-oxidized cholesterol-24-yl] ethyl} cholesteric acid. This compound has the following physicochemical properties:
- ** Appearance **: Usually appears as a white to off-white crystalline powder. This is due to the presence of multiple cyclic structures and longer carbon chains in its molecular structure. These structures are sequentially arranged in the solid state to form a crystalline form, which exhibits a white or off-white appearance when exposed to light.
- ** Solubility **: It is easily soluble in organic solvents such as chloroform and dichloromethane, and also has a certain solubility in ethanol, but it is difficult to dissolve in water. From a molecular perspective, there are large non-polar hydrocarbon groups in the molecule of this compound, such as steroid parent nuclei and long carbon chains, which make it have strong lipophilicity; while the hydroxyl groups in the molecule have a certain hydrophilicity, they are relatively weak, which is not enough to overcome the hydrophobicity of the whole molecule, so it has better solubility in organic solvents and poor solubility in water.
- ** Melting point **: This substance has a specific melting point range, and its molecules are closely bound through Van der Waals forces, hydrogen bonds, and other interactions. When heated, the molecule obtains enough energy to overcome these interactions and begins to transform from a solid state to a liquid state. This transition temperature is the melting point. Its melting point characteristics can be used for identification and purity judgment. If the sample purity is high, the melting point range is narrow and close to the theoretical value; if it contains impurities, the melting point will be reduced and the melting range will be widened.
- ** Chemical stability **: It is relatively stable at room temperature, dry and protected from light. However, due to the presence of hydroxyl groups in the molecule, in the environment of strong acid, strong base or strong oxidant, the hydroxyl group may undergo reactions such as dehydration and oxidation, resulting in changes in the molecular structure. For example, under the action of concentrated sulfuric acid, the hydroxyl group may dehydrate to form double bonds; under the action of strong oxidant, the hydroxyl group may be oxidized to carbonyl and so on.

To prepare 2- {[ (3α, 5β, 6β, 7β, 8β, 9β, 14β) -3,6,7-trihydroxy-24-oxidized cholesterol-24-yl] ethyl} cholesteric acid, the following method can be used.
First take a suitable cholesteric starting material, often a cholesterol derivative with a specific configuration is preferred. In ancient theory, it requires fine operation and various chemical reactions.
First, when a specific hydroxyl functional group is introduced at a designated location. Selective oxidation can be used to precisely control temperature, time and select an appropriate oxidant to form hydroxyl groups at the 3,6,7 positions. The oxidizing agent used, or a mild high-valent metal salt, is carefully reacted in a suitable solvent environment, such as alcohols or halogenated hydrocarbon solvents, to ensure the accurate oxidation check point.
As for the oxidation of the 24-position, the appropriate reaction path should be followed. Or first shield its unwanted functional groups with specific protective groups, and then use suitable oxidation reagents, such as peroxides, to oxidize the 24-position carbon atoms to the desired oxidation state with the help of the catalytic system.
After the oxidation modification of each key position is completed, when the ethyl connection is constructed. This step often depends on the formation of carbon-carbon bonds, such as the classical Wittig reaction or the Grignard reaction. If the Wittig reaction is used, a suitable phosphorus ylide reagent needs to be prepared, and it needs to be reacted with the modified cholesteric derivative under appropriate conditions to form a target carbon-carbon bond connection.
After each step of the reaction, the protective group needs to be carefully removed, so that the final pure 2- {[ (3α, 5β, 6β, 7β, 8β, 9β, 14🥰) -3,6,7-trihydroxy-24-oxidized cholesteric-24-yl] ethyl} cholesteric acid product. Each step requires fine control of the reaction conditions to achieve the purpose of high purity product, and requires separation methods such as recrystallization and column chromatography to obtain pure products.
