Abstract

The reaction of triptolide and its analogues with a fluorinating agent, that is, bis(2-methoxyethyl)aminosulfur trifluoride (Deoxo-Fluor) or (diethylamino)sulfur trifluoride (DAST), was studied. One of the fluorinated products, 14beta-dehydroxy-14beta-fluoro triptolide, was found to be more cytotoxic than the parent natural triptolide.
