A series of trioxanes featuring sulfide, sulfone. and sulfonamide snbstituents in diverse positions has been prepared. Structure-activity relationship (SAR) generalizations highlight two major factors controlling the antimalarial potency of these new chemical entities: (1) the proximity of the sulfur-containing substituent to the crucial peroxide bond and (2) the oxidation stale of the sulfur-containing substituent. Generally, sulfones are more antimalarially potent than the corresponding sulfides. (C) 2000 Elsevier Science Ltd. All rights reserved.

Thioacetal artemisinin derivatives, in particular, 10alpha-phenylthiodihydroartemisinins (5), 10beta-benzenesulfonyl-9-epidihydroartemisinin (9) and 10alpha-mercaptodihydroartemisinin (11), exhibit good growth inhibition activity against HUVEC proliferation at the concentration level of 1 muM.
