Abstract A piperazine-amide derivative(2) was obtained by one-pot method, using dihydroartemisinin(DHA), oxalyl chloride and piperazine as materials. Six novel piperazine-aliphatic amide derivatives(4a~4f) were synthesized by acylation of 2 with aliphatic acyl chloride.The structures were characterized by 1H NMR, 13C NMR, IR and HR-ESI-MS. The anti-cancer activities in vitro of 4a~4f against human hepatoma SMMC-7721 cell lines were investigated by MTT method. The preliminary bioassay results showed that 4a~4f inhibited the proliferation and induced the apoptosis of SMMC-7721. Especially dihydroartemisinin piperazinechlorine acetamide(4c) had the best inhibition activity against SMMC-7721 with IC50 0.05 μM, which was superior to artemisinin(IC50 0.53 μM) and DHA(IC50 0.52 μM).
