Synthesis, spectral analysis and bioactivity of new coumarin derivatives are described in this paper. Eight new coumarin derivatives were synthesized in moderate to good yields by condensation of 4-chloro-3-nitrocoumarin and the corresponding heteroarylamine. The synthesized compounds were tested for their

A preliminary exploration of coumarin derivatives as novel multidrug resistance (MDR) modulators was carried out to determine the basic features of the structure responsible for the MDR reversal activity. Among 44 coumarins, 14 compounds moderately induced the reversal of MDR
