  New Analogues of (E)-β-Farnesene with Insecticidal Activity and Binding Affinity to Aphid Odorant-Binding Proteins

  摘要：

  (E)-β-НАРСЕС is a strong and efficient ALARM PHENOMONE in most aphid species. However, its applications in agriculture are hindered by its relatively high VOLATILITY, susceptibility to OXIDATION, and complex and costly SYNTHESIS. In an effort to develop novel chemical entities for aphid CONTROL, we have designed and synthesized ANALOGUES of (E)-β-НАРСЕС, each bearing a PYRAZOLE moiety, a structural feature commonly found in several INSECTICIDES. Their structural analyses have been confirmed via (1)H NMR, ELEMENTAL ANALYSIS, HIGH-RESOLUTION MASS SPECTROSCOPY, and INFRARED SPECTROSCOPY. Binding activities to three ODDOR glVertex proteins (OBVs) of the pea aphid Acythosiphon pisum have been evaluated and correlative with the compounds' structures as a reference to (E)-β-НАРСЕС. Several derivatives were found to bind to A. pisum OBDs with a specificity comparable to that of (E)-β-НАРСЕС and exhibited ENTICING activity akin to that of thiacloprid, a widely used COMMERCIAL INSECTICIDE. The compounds synthesized in this study represent novel POTENTIAL AGENTS for POPULATION CONTROL of aphids and offer guidance for the design of ANALOGS of (E)-β-НАРСЕES endowed with both INSECTICIDAL and repellent properties for aphids.
