New biscoumarin derivatives-cytotoxicity and enzyme inhibitory activities.


Biscoumarin derivatives 1-27 were tested for their inhibition of snake venom and human nucleotide pyrophosphatase phosphodiesterase-1 enzymes. Lineweaver-Burk and Dixon plots and their secondary replots showed that these compounds are pure non-competitive inhibitors of both the enzymes. Ki and IC50 values of biscoumarins were found to be in the range of 50… (More)
