C-10 CARBON-SUBSTITUTED ARTEMISININ-LIKE TRIOXANE COMPOUNDS HAVING ANTIMALARIAL, ANTIPROLIFERATIVE AND ANTITUMOUR ACTIVITIES

The present invention provides a two-step procedure for the replacement of the pyranose anomeric 10-OH group in dihydroartemisinin by a variety of carbon nucleophiles, resulting in the novel C-10 carbon-substituted trioxanes of structure: wherein, when n is 1, R is selected from a group of unsubstit...

Beschreibung
Zusammenfassung:	The present invention provides a two-step procedure for the replacement of the pyranose anomeric 10-OH group in dihydroartemisinin by a variety of carbon nucleophiles, resulting in the novel C-10 carbon-substituted trioxanes of structure: wherein, when n is 1, R is selected from a group of unsubstituted or substituted aryls, heteroaryls, polyethylene glycol, acetylenics, or benzoylmethylenes, or alkanoylmethylenes; or when n is 2, R is selected from a group of unsubstituted or substituted aryls, heteroaryls, polyethylene glycol, alkenyls, alkyls, diketones or bis-acetylenes; or when n is 3, R is selected from a group of unsubstituted or substituted aryls, heteroaryls, polyethylene glycol, alkenyls, alkyls, diketones or bis-acetylenes.
