Synthesis and anti-cancer, anti-metastatic evaluation of some new fluorinated isocoumarins and 3,4-dihydroisocoumarins

Synthesis of some fluorinated isocoumarins and 3,4-dihydroisocoumarins is reported. Structures of the synthesized compounds were confirmed by spectral and elemental analysis. All the synthesized compounds were evaluated for their antimetastatic activity and anti-cancer activity against breast cell line (MCF-7). Among all the tested compounds 3h [3-(3',4'-difluorophenyl)isocoumarin] has shown excellent antimetastatic activity, however the growth inhibitory response of the tested compounds [3a-h, 4a-h, 5e-h, 6a-h and 7a, c, d] for MCF-7 human breast carcinoma cell line was moderate at higher concentrations (100-400 mu M) and negligible at lower concentrations.
