Semi-synthesis of phenolic-amides and their cytotoxicity against THP-1, HeLa, HepG2 and MCF-7 cell lines.

In the present study, we derivatized several hydroxycinnamic and hydroxybenzoic acids to phenolic amides (PAMs) one step BOP mediated amide coupling reactions. Fifteen PAMs were synthesized in >40% yields and were screened for their cytotoxic activities against four cancer cell lines: THP-1 (leukaemia), HeLa (cervical), HepG2 (liver), and MCF-7 (breast), in comparison to 5-flurouracil (5-FU). Four amides showed IC ranging from 5 to 55 µM against all four cell lines. In contrast, tetradecyl-gallic-amide () affected only THP-1 leukaemia cells with IC of 3.08 µM. The activities of these compounds support the promise of phenolic amides as anticancer agents.
