A series of alpha-branched alpha,beta-unsaturated ketones were prepared via boron trifluoride etherate mediated reaction between arylalkynes and carboxaldehydes. The evaluation of the antiproliferative activity over hematological (NB4) and solid cancer (A549, MCF-7) cell lines provided a structure-activity relationship. 5-Parameter QSAR equations were built which were able to explain 80%-92% of the variance in activity. The resulting selective lead compound showed IC50 value 0.6 mu M against the hematological cell line and did not cause apoptosis, but blocked cell cycle in G0/G1. Moreover, it was demonstrated that this compound enhances and accelerates retinoic acid induced granulocytic differentiation. (C) 2015 Published by Elsevier Masson SAS.
