Abstract:Two new analogues with ketoxime-substituted of isoandrographolide were synthesized by selective dehydroxylation, selective hydroxyl protection, oxidation, de-protection and oximation reactions using andrographolide as the starting material. The total yield were 54.3% and 59.1% respectively. The obtained analogues of isoandrographolide were characterized by 1H-NMR, 13C-NMR, ESI-MS and Elemental Analysis.
Key words:isoandrographolide; ketoxime; isoandrograpolide-3-ketoxime
