Abstract:
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 IC
50 values of 0.14 μmol·L
-1.
