WebThese compounds were purified by simple column chromatography and successfully analyzed using 'H NMR, IR and FAB-MS techniques. AB - Spiro 1,2,4-trioxane are synthetic derivative of artemisinin (1,2,4-trioxane is supposed to be a pharmacophore of artemisinin) which is a well known antimalarial drug from leaves of Artemisia annua found in China. WebThe cyclic peroxide moiety is the central pharmacophore in artemisinin with the 1,2,4-trioxane group being a part of a bicyclo[3.2.2]nonane skeleton. A structural simplification which has been extensively realized synthetically and examined with respect to antimalaria-activity is the 3-spiroannelated 1,2,4-trioxane structure .
