Analogues of annonaceous acetogenins were built up from 5-iodofuran-2-carbaldehyde and undec-10-ynoic acid or undec-10-ynol by a Sonogashira reaction, followed by a Grignard reaction and a mercury catalysed hydratisation. The cytotoxicity was evaluated with MTT assay ((3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide colorimetric assay for measuring cellular proliferation) against HL cells and at the National Cancer Institute (NCI).
