アンドログラホリド

化学的特性white square prism or flaky crystals (ethanol or methanol) and odorless, with a bitter taste. dissolved in boiling ethanol, slightly soluble in methanol or ethanol, very slightly soluble in chloroform, and almost insoluble in water. Since andrographolide has an ester structure, it is easy to hydrolysis, open loop and isomerization in the aqueous solution to affect the drug stability. At lower temperature, the stability of andrographolide is better; it is unstable in alkaline conditions, and its instability increased with the increase in alkaline strength. The most stable pH value is 3–5. Andrographolide is more stable in chloroform.

説明Andrographolide is a diterpene lactone compound extracted from Andrographis. paniculata (Burm. F) Nees. Andrographis paniculata is also known as lanhelian, yijianxi, zhanshecao, kucao, kudancao, etc. Since this product originates in India, it is also known as Indian grass. This product is dry ground part of Jupiteraceae plant Andrographis paniculata (conus) may originate in South Asia. It is commonly cultivated in China such as in Fujian, Guangdong, Hainan, Guangxi, and Yunnan and also in Australia and was also introduced in Jiangsu and Shaanxi.Andrographis paniculata is commonly used in traditional Chinese medicine. Its ability of relieving “snake venom, and internal injuries cough” was recorded in “Lingnan herbal medicine records.” “Quanzhou Materia Medica” described it as “heat-clearing and detoxifying, anti-inflammatory, detumescence and inhibition throat inflammation, dysentery and high fever.”The above ground part of Andrographis paniculata contains andrographolide, neo-andrographolide, 14-deoxygenated andrographolide, etc., and the root contains mainly flavonoids.

天然物の起源Andrographis is found growing wild in India and Sri Lanka and is cultivated in many other parts of the world.

来歴In 1911, Gorter firstly isolated a crystalline substance from Andrographis paniculata, identified it as a diterpene lactone compound, and named it andrographolide .Andrographolide structure is complex and difficult to artificially synthesize, so it is often extracted from the plant.Andrographolide water solubility is poor and its bioavailability is low; its pharmacological effects are extensive but weak, so the preparation requirements are strict. Therefore, from the 1970s, drugs and organic chemical researchers have done a lot of work in the modification and transformation of andrographolide, mainly concentrated in the α, β-unsaturated lactone double bond Michael addition, redox, selective esterification of hydroxyl groups, oxidation and substitution reactions, intramolecular cyclization, replacement of lactone rings, etc. They had obtained a number of new derivatives. In the research of pharmacological effects, the main study of the andrographolide derivatives focuses on antitumor, antivirus, and other biological activities and has made some progress .

使用Andrographolide is a labdane diterpenoid. Andrographolide is the main bioactive component isolated from the medicinal plant Andrographis paniculata. It has a broad range of therapeutic applications including anti-inflammatory and anti-platelet aggregation activities and potential antineoplastic properties. Andrographolide showed significant antihepatotoxic action in P. berghei K173- induced hepatic damage in M. natalensis. Andrographolide inhibits tumor necrosis factor-α (TNF-α)-induced intercellular adhesion mol.-1 (ICAM-1) expression and adhesion of HL-60 cells onto human umbilical vein endothelial cells (HUVEC), which are associated with inflammatory diseases. These findings suggest that Andrographolide may have potential as a cardiovascular-protective agent.

一般的な説明Andrographolide, a bioactive diterpene lactone, is the main constituent of Andrographis paniculata, a plant used in traditional medicines. It is known to have different biological activities such as anti-inflammatory, anti-malarial, anti-cancer and hepatoprotective activity. It also shows potent anti-viral effect against dengue virus.
