一般描述
Neoandrographolide is a major diterpenoid isolated from Andrographis paniculata NEES (AP), a shrub belonging to the Acanthaceae family. It exhibits antihepatotoxic effect against carbon tetrachloride-induced hepatotoxicity. It also shows protective effects against galactosamine and paracetamol-induced intoxication in rats. It also helps in the suppression of human immunodeficiency virus type 1 (HIV)-induced cell cycle dysregulation and leads to a rise in CD4+ lymphocyte levels of HIV-1 infected individuals.
应用
Neoandrographolide may be used as an analytical reference standard for the quantification of the analyte in the leaves of Andrographis paniculata using chromatography techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

The bioactive diterpenes andrographolide and neoandrographolide from the leaves of Andrographis paniculata NEES (Acanthaceae) were successfully separated by counter-current chromatography. A single 280-min separation yielded 189 mg of 99.9% andrographolide and 9.5 mg of 98.5% neoandrographolide applying water-methanol-ethyl acetate-n-hexane (2.5:2.5:4:1)

An attempt has been made to develop a method by which to determine the chemical fingerprint of Andrographis paniculata (Acanthaceae). High-performance thin layer chromatography (HPTLC) was used to analyse hexane, chloroform, methanol and water extracts of leaves of A. paniculata.

Studies were performed to investigate the prohormone/proprotein convertase (PC)-inhibitory properties of chemical constituents of the medicinally active plant Andrographis paniculata (AP; from the family Acanthaceae), also known as 'King of Bitters'. Among the individual components tested against the clinically important

The biotransformation of neoandrographolide (1) was investigated by using Aspergillus niger (AS 3.739). Five products were obtained and identified as 8(17),13-ent-labdadien-16,15-olid-19-oic acid (2), 19-hydroxy-8(17),13-ent-labdadien-16,15-olide (3), 18-hydroxy-8(17),13-ent-labdadien-16,15-olid-19-oic acid (4), 3alpha-hydroxy-8(17),13-ent-labdadien-16,15-olid-19-oic acid (5) and 8beta,19-dihydroxy-ent-labd-13-en-16,15-olide (6) by spectroscopic and chemical means.
