Synthesis and antiproliferative activity of α-branched α,β-unsaturated ketones
摘要:
A series of alpha-branched alpha,beta-unsaturated ketones were prepared in a straightforward manner by the acid catalyzed coupling between arylalkynes and carbaldehydes. The method also allows producing as side product chalcone analogs bearing an additional alpha,beta-unsaturated arylketone in the molecular scaffold. The evaluation of the antiproliferative activity in the human solid tumor cell lines HBL-100 (breast), HBL (cervix), SW1573 (non-small cell lung), T-47D (breast) and WiDr (colon) provided a structure activity relationship. Overall, the compounds presented active against the resistant cancer cells T-47D. The resulting lead, displaying an unprecedented chalcone scaffold, showed GI(50) values in the range 0.32-0.53 mu M against all cell lines tested. The methoxy group present in the lead might play an important role in the activity. (C) 2013 Elsevier Masson SAS. All rights reserved.
