 Studies have shown that Salidrosid e treated PC12 cells in advance significantly reduced MPP+-induced cell apoptosis compared with the control group, and at the same time, the attenuation of mitochondrial membrane potential MMP was also significantly reduced, indicating that salidroside prevented MPP(+) from inducing cell apoptosis in PC12 cells, at least in part through the activation process mediated by the PI3K/Akt pathway.  The above studies show that salidroside also has an important intervention effect in the human body in combating hypoxia and regulating apoptosis pathways. At present, there are relevant important combinations in clinical practice for the treatment of certain hypoxia-related diseases, which deserve further study. Salidroside also has anti-inflammatory effects. Inflammation is the body's adaptive response to tissue damage and infection caused by the external environment, but excessive inflammatory response can lead to various functional disorders in the...

Matrine  Sophora flavescens Chemical composition As early as the early 1930s, the Soviet Union began to study it abroad, and China began in 1972. The focus of research at home and abroad is on alkaloids. The alkaloids extracted, separated and identified from Sophora flavescens plants in China mainly include oxymatrine (C15H24N2O2), matrine (C15H24N2O), isomatrine (Iosmatrine, C15H24N2O), hydroxymatrine (sophor-anol), sophocarpine (C15H22N2O), N-oxysophocarpine (C15H22N2O2), sophoramine, sophoridine (Sophoridine, C15H24N2O), Aloperine, sparteine, N-methylcytisine, anagyrine, bap-iifoline, sophocarpine, d-matrine, d-isomatrine, d-oxymatrine, l-anagyrine, l-methyleytisine, l-baptifoline, kurarid-in, sophoranol (C15H24N2O2), sophoranhol N-oxide (C15H24N2O3), N-methylcytisine (C12H16N2O), and other alkaloids. Flavonoids: The flavonoids contained in Sophora flavescens are mostly dihydroflavones and dihydroflavonols, and there are also flavones, isoflavones, chalcones, etc. The flavonoids...

 Customized and generic  pharma intermediates Pharmaceutical intermediates include generic and customized products. Customized business models can generally be divided into CRO (contract research and development outsourcing) and CMO (contract manufacturing outsourcing). With the continuous development of the pharmaceutical industry, the CDMO (contract research and development outsourcing) model has gradually emerged. CDMO companies not only provide production services, but also participate in the customer's research and development process, provide customers with process improvements or optimization, achieve high-quality large-scale production, and reduce production costs4. In summary, pharmaceutical intermediates are classified in a variety of ways. They can be classified according to their chemical structure and application field, or according to their position and degree of customization in the drug synthesis process. These classifications reflect the importance and diversi...

 Classification of pharmaceutical intermediates bulk pharmaceutical intermediates are one or more chemical substances generated during the synthesis of drugs, and they are key steps in the production of the final active pharmaceutical ingredients (API). There are many types of pharmaceutical intermediates, depending on the chemical structure and synthesis route of the target drug. The following are some common classifications of pharmaceutical intermediates1: Category Example compound Application field Benzene ring intermediates - anticancer drugs, cardiovascular drugs Heterocyclic compounds Pyridine, thiophene, imidazole, etc. Common intermediates in pharmaceuticals Amino acids and peptides - bioactive molecules and drugs (such as insulin) Carboxylic acids and their derivatives Benzoic acid, malonic acid, etc. Anti-inflammatory drugs, antibiotics Ester and ether compounds - analgesics, sedatives In addition, pharmaceutical intermediates can also be classified according to their a...
