Abstract

In recent years, concerns over the potential impact of synthetic pesticides on the environment have promoted the research and development of environmentally friendly “green” pesticides. In the current study, we utilized a green biomimetic insecticide, 1,5-bis-(5-nitro-2-furanyl)-1,4-pentadien-3-one (compound C), to examine its cytotoxicity on an insect cell line, Drosophila melanogaster (SL2). Results from MTT assay showed cells treated with 100 µM of compound C for 48 h significantly inhibited the growth of SL2 cells by 87.71±0.96%. We subsequently attempted to illustrate the act on mechanism of compound C at the cellular level and found that it initiated apoptosis through a mitochondrial-dependent mechanism that increased the activity of caspase-3 and altered the cell cycle. These results suggest that the green biomimetic insecticide, compound C, is a novel and potent inducer of insect cell apoptosis.
