It is the major labdane diterpenoid isolated from Andrographis paniculate. It exhibits antiviral, anti-inflammatory, and anticancer activities. The underlying mechanism is the inhibition of the mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) signaling (specifically p38 MAPK/ERK1/2) pathway and downstream transcription factors such as nuclear factor kappa B (NF-κB) and nuclear factor of activated T cells (NFAT). Andrographolide is also confirmed with chemopreventive effects against and the inhibitory effects on cancer cell growth in breast, colon, epidermoid, gastric, liver, leukemia, myeloma, peripheral blood lymphocytes, and prostate cancers. Andrographolide has been used for liver complaints and fever, and as an anti-inflammatory and immunostimulant. Andrographolide exerts anti-growth and pro-apoptotic effects on human rheumatoid arthritis fibroblast- like synoviocytes, the main cellular constituent of pannus, that combined with a massive infiltration of lymphocytes and macrophages, invades and destroys the local articular structure. Thereby, andrographolide is proposed to be used in Rheumatoid Arthritis and other autoimmune diseases. References [1] Mari a A. Hidalgo, Juan L. Hancke, Juan C. Bertoglio and Rafael A.

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. Chemical Properties colorless Plates Physical properties Appearance: white square prism or flaky crystals (ethanol or methanol) and odorless, with a bitter taste. Solubility: 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 Occurrence Andrographis is found growing wild in India and Sri Lanka and is cultivated in many other parts of the world. History 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 . Uses Andrographolide may be used as a reference standard for the determination of andrographolide in: Leaves of Andrographis paniculata by soxhlet extraction-recrystallization-column chromatography purification followed by analyses using reversed phase high performance liquid chromatography (RP-HPLC) as well as gas chromatography-mass spectrometry (GC-MS). Roots of Andrographis paniculata by HPLC with diode array detection (DAD), gas chromatography-mass spectrometry (GC-MS) and LC coupled to tandem mass spectrometry (MS/MS) equipped with electrospray ionization (ESI) and multiple reaction monitoring (MRM) mode of detection. Stems of Andrographis paniculata by ultra-HPLC combined coupled to triple quadrupole-linear ion trap mass spectrometry (QqQLIT-ESI-MS/MS) with MRM detection. Rat plasma samples by protein precipitation and subsequent ESI-LC-MS/MS determination using MRM detection. Uses Andrographolide is a labdane diterpenoid. Andrographolide is the main bioactive component isolated from the medicinal plant Andrographis paniculata. 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. Uses antineoplastic Definition ChEBI: A labdane diterpenoid isolated from the leaves and roots of Andrographis paniculata that exhibits anti-HIV, anti-inflammatory and antineoplastic properties. General Description 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. Biochem/physiol Actions Diterpenoid lactone with anti-inflammatory properties. It blocks T-cell proliferation to allogenic stimuli and the chemotactic migration of macrophages induced by complement.
