A series of new iodinated-4-aryloxymethylcoumarins 6, 8 and 10 have been obtained from the reaction of
various 4-bromomethylcoumarins 4 with 2-iodophenol 5, 3-iodophenol 7 and 4-iodophenol 9 respectively.
All the title compounds were screened for anticancer activity against two cancer cell lines (MDAMB
human adenocarcinoma mammary gland and A-549 human lung carcinoma) and two mycobacterial
strains (Mycobacterium tuberculosis H37 RV and Mycobacterium phlei). The SAR results indicate that nine
compounds are potent, among these 10h and 10i having chlorine are most effective. This is the first
report assigning in vitro anti-mycobacterial, anticancer and structureeactivity relationship for this new
class of iodinated-4-aryloxymethyl-coumarins.
