Abstract
Abstract42 novel diacylhydrazine derivatives containing furan were synthesized by the reaction of 5‐substituted phenyl‐2‐furoyl chloride with substituted benzohydrazide in anhydrous dichloromethane under reflux. Their structures were confirmed by IR, 1H NMR, MS and elemental analysis. Insecticidal and antitumor activity of these new compounds was evaluated. The preliminary bioassays showed that the target compounds exhibited larvicidal activity to the Mythimna separate, some of them exhibited good or moderate larvicidal activity. At the concentration of 0.1%, compounds I2, I4, I5, and III1 showed 95.0%, 90.0%, 95.0% and 95.0% larvicidal activity to Mythimna separate respectively. Some compounds such as I2, I4, I5 and III1 showed the typical IGRs' activity, which could induce the larvae premature, abnormal, and lethal larval molt. Results of anticancer activity indicated that some compounds exhibited potential activity against some human cancer cell lines, for example, I1 and IV showed good activity to the BGC‐823 and the inhibitory rates were 60.86% and 61.94% respectively at 10 µmol/L.
