Abstract: A new series of O-substituted chalcone derivatives bearing an/a allyl-, prenyl- or propargyl-substituent at different positions of rings A and B and their derivatives as drug leads, was designed, synthesized, and characterized. The chalcone derivatives were synthesized via base catalyzed Claisen-Schmidt condensation in MeOH or EtOH solutions of appropriately substituted aromatic ketones with O-allyl, and O-propargylvanillin, respectively. The intermediates O-substituted phenylketone derivatives were firstly synthesized by nucleophilic substitution reaction. All the newly synthesized compounds were characterized by IR, NMR spectral data and elemental analyses. A preliminary cytotoxicity was performed with the compounds (1a, 1b, 2a, 2b, 3a, 3b, 4a, 5a-f, 6a-d, 7a-d) and the positive control, doxorubicin towards CCRF-CEM leukemia cells. Amongst them, compounds 1a, 2a, 5b-d, 6b, 7a, 7c and doxorubicin displayed IC values below 20 µM while other compounds were less or not active at up to 50 µM. Remarkably interesting cytotoxic effects, with IC values below 1 µM were recorded with 5c against HCT116 p53 colon adenocarcinoma cells, 5e against CCRF-CEM cells and MDA-MB-231-BCRP breast adenocarcinoma cells, and 6b against HCT116 p53 cells and HCT116 p53 cells.
