- On the basis of the sulfonylurea receptor (SUR) protein binding site for diflubenzuron and glibenclamide, 15 new benzoylphenylureas containing amide and sulfonate groups were designed and synthesized. Their structures were characterized by ¹H nuclear magnetic resonance (NMR) and elemental analysis [or high-resolution mass spectrometry (HRMS)]. The larvicidal activities of the new compounds against oriental armyworm and diamondback moth were evaluated. Compound II-3 showed nearly the same level of insecticidal activity against oriental armyworm as commercial insecticide flucycloxuron and, thus, emerged as a new lead compound for the development of new benzoylurea insecticides.
