[Synthesis and bioactivities of novel dihydroartemisinin-piperazine derivatives containing sulfonamide].

Dihydroartemisinin is an important derivative of artemisinin. We used dihydroartemisinin as the starting material, through esterification, amination and acylation, a series of novel piperazine-sulfonamide contained dihydroartemisinin derivatives were firstly synthesized and their chemical structures were confirmed by IR, 1H NMR, 13C NMR and HR-MS. X-diffraction was used to determine the final configuration of the compound 3c. And the in vitro anti-HeLa activities of compounds 3 were analyzed with CCK-8 method. The preliminary bioassay test shows that compound 3 showed the best inhibition activities against HeLa with IC50 values of 0.14 micromol x L(-1).
