Neoandrographolide Usage And Synthesis
DescriptionAndrographic plants are derived from the aerial parts of Andrographis paniculata (Burm.f.) Nees and known by various vernacular names such as “chunlianqiuliu,” “yijianxi,” “lanhelian,” “kudancao,” “jinxiangcao,” “jinergou,” “India grass,” and “bitter grass.” Andrographis paniculata is planted in South and Southeast Asia, India, and Australia. This herb is also cultivated in Fujian, Guangdong, Hainan, Guangxi, Yunnan, Jiangsu, and Shaanxi provinces in China. Andrographis paniculata has been used to treat colds, sore throat, mouth sores, cough, diarrhea dysentery, and so on. Andrographis paniculata contains diterpene lactone compounds, and they have anti-inflammatory and antimicrobial activities. The main active ingredients include andrographolide, neoandrographolide, deoxy andrographolide, dehydrated andrographolide, and so on. Andrographis paniculata has been included by US Pharmacopeia.
Physical propertiesAppearance: Neoandrographolide is a colorless column crystal that has been isolated from the stem and leaves of Andrographis paniculata. Melting point: 167– 168?°C. Specific optical rotation: ?48°(pyridine); ?45°(c?=?1, absolute ethanol). Solubility: Soluble in methanol, ethanol, acetone, and pyridine and slightly soluble in chloroform and water but insoluble in ether and petroleum ether.
HistoryThe chemical constituents of Andrographis paniculata are mainly lactones and flavonoids, including the lactone compounds such as andrographolide and dehydrated andrographolide. In 1952, Kleipool first reported the separation of andrographolide from Andrographis paniculata . In 1968 and 1971, W.?R. Chan et?al. identified the chemical structure and stereostructure of andrographolide. In the 1990s, a variety of diterpene lactones were isolated from the aerial part and the lotus leaf of Andrographis paniculata, such as andrographolide, neoandrographolide, dehydroandrographolide, deoxyandrographolid, deoxyandrographiside, 8-methylandrograpanin, 3-dehydrodeoxyandrographolide, andrograpanin, and 3-oxo-14-deoxy-andrographol,and also some flavonoids and sitosterol and daucosterol compounds . Until now, more than 40 diterpene lactone components and more than 70 flavonoids have been found from Andrographis paniculata. There are sterols, organic acids, diterpene alcohols, diterpene acid salts, and cycloalkene ether also found from Andrographis paniculata .Since the 1970s, pharmacists and organic chemists have done a lot of work on the modification of andrographolide, mainly in Michael addition of α, β-unsaturated lactone double bonds and three hydroxyl groups selective esterification, oxidation and substitution reactions, redox reduction of double bonds, intramolecular cyclization, and lactone ring replacement reactions , and the resulting andrographolide derivatives or analogues can improve the antibacterial, anti-inflammatory, cardiovascular system, immunomodulation, and antitumor activities.
UsesNeoandrographolide is one of the principle diterpenoids isolated from A. paniculata, a well-recognized medicinal plant in Asia.
IndicationsNeoandrographolide is available in the Pharmacopoeia of the People’s Republic of China (1977).Neoandrographolide and andrographolide are the main active ingredients of a variety of pharmaceutical preparations containing the Andrographis herb, such as andrographolide capsules, andrographolide tablets, Andrographis injection, potassium dehydroandrographolide succinate injection, Andrographis tablets, Xiaoyan Lidan tablets, and Fufang chuan xin lian tablets. These drugs are mainly used for treating acute bacterial dysentery, acute gastroenteritis, upper respiratory tract infection, acute tonsillitis, pharyngitis, etc. In addition, they are also used to treat malignant hydatidiform mole and choriocarcinoma.
PharmacologyAndrographis paniculata has detoxifying abilities, reduces swelling, and relieves pain. The four major diterpene lactones in Andrographis paniculata have antipyretic and anti-inflammatory activities against 2,4-dinitrophenol or endotoxin-induced fever and egg white-induced edema or croton oil-induced inflammatory models.Animal experiments have shown that Andrographis paniculata has inhibited and delayed the body temperature elevation of persons with infections caused by pneumococcus and hemolytic streptococcus. It also can be used for treating cough and asthma and especially for treating acute bacterial dysentery, acute gastroenteritis, upper respiratory tract infection, acute tonsillitis, pharyngitis, and so on.The active ingredients andrographolide and neoandrographolide inhibit lipopolysaccharide-induced NO production in the mouse peritoneal macrophages . Neoandrographolide at the high concentration can inhibit the macrophage outbreak caused by LPS and the proliferation of lymphocytes and can synergistically enhance the PMA stimulating effect on the respiratory outbreak. The possible mechanism is related to its ROS scavenging activity .
Clinical UseNeoandrographolide is one of the main active ingredients of the natural plant Andrographis paniculata. But there is no formulation of neoandrographolide. Andrographis injection has been clinically used, but it has several side effects.
