Abstract

Parameter focusing on the DNA topoisomerase-Iinhibition with X-substituted phenyl substituents in 1-(2-furyl)-3-phenylpropenone derivatives as inhibition material were analyzed. From the basis on the results the inhibition on DNA topoisomerase I suggested that the inhibition activities of X-substituted phenyl substitutents would depend largely on the net charge of $\beta$-carbon atom, LUMO energy (e.v.) and STERIMOL parameter B$_{5}$ (width) of X. Among them, non-substituent (X=H), 1 and 2,2-dichloro substituent, 4 showed the highest DNA topoisomerase-I inhibition activity.y.
