Six classes of coumarin derivatives (i.e. 3-alkyl-4-methylcoumarins, pyranocoumarins, coumarin carboxamides, quaternary ammonium coumarins, 7-aminocoumarins, and 4-aminocoumarins) were synthesized and evaluated for inhibition of cell proliferation of colon adenocarcinoma (HT-29), breast carcinoma (MDA-MB-468 or MCF-7), and human ovarian adenocarcinoma (SK-OV-3) cells. C-3-Alkyl substituted analogs of 4-methylcoumarins and pyranocoumarins, 5 and 6, inhibited the cell proliferation of MDA-MB-468 and SK-OV-3 cells by 53-74%, while 3-decyl substituted pyranocoumarin 10 and triethyl substituted quaternary ammonium coumarin derivative 29 inhibited the cell proliferation of HT-29 and SK-OV-3 cells by 63-72% at a concentration of 50 μM. Among all the compounds studied, C-3 decyl substituted quaternary ammonium coumarin derivative 25 exhibited the highest Src kinase inhibition with an IC 50 value of 21.6 μM.
