RESUMO
Five novel acetogenin analogues with a furan, thiophene, or thiazole ring were synthesized, and their inhibitory activities toward human cancer cell lines were evaluated. The analogues showed more potent activities than natural acetogenin. One of them, the thiophene-3-carboxamide analogue, strongly inhibited the growth of human lung cancer cell line NCI-H23 in the xenograft mouse assay without critical toxicity.

Five novel hybrid molecules of annonaceous acetogenins and insecticides targeting mitochondrial complex I were synthesized and their growth inhibitory activities against 39 human cancer cell lines were investigated. It was revealed that the connecting group between the N-methylpyrazole part and the hydrophobic alkyl chain bearing the THF ring influenced their biological activities significantly. Amide-connected analog 2, in particular, showed selective and very potent activity (<10 nM) against some cancer cell lines.
