The present report describes development of a novel, bifunctional molecule possessing both selective antiproliferative activity and siRNA transfection ability. We synthesized a series of cationic lipobenzamides and screened for in vitro anticancer activities against a panel of cancer and non-cancer cells. The molecule with a ten carbon chain-length (C10M) significantly inhibited proliferation of cancer cells via arresting the cell cycle predominantly in the G1 phase; but did not affect non-cancerous cells. C10M effectively mediated siRNA delivery in vitro. The combined anticancer effect of the delivery of C10M together with its survivin-targeting siRNA cargo was significantly (p < 0.05) superior to that of agent alone. To our knowledge, this is the first report of a dual-purpose molecule with intrinsic anticancer activity and suitability for use in siRNA delivery. (C) 2012 Elsevier Masson SAS. All rights reserved.
