Abstract
Novel neuroactive insecticides are discovered/registered differently, have a lower value in use, and exert their physiological actions in manners distinct from neuroactive pharmaceuticals, but there are clear similarities in their biochemical modes of action. Insecticides are generally discovered using whole pest insect screens, and this eases difficulties in 'translational science' from laboratory to field, as opposed to pharmaceutical translation from biochemical or cell-based targets to animal models to human clinical trials to registered drug. This paper examines recent trends in pharmaceutical science and identifies some technologies which may represent complementary approaches to insecticide discovery screening and mode of action determination beyond the sound processes in common practice today. Examples will be drawn from nanoparticle delivery of neuroactives, unique ligand-polymer conjugates, proposed advances in insect cell culture following from pharmaceutical cell biology, and laboratory or organ-on-a-chip approaches. It is hoped that these concepts will stimulate novel thinking which may enable discovery of efficacious new neuroactive insecticides. © 2020 Society of Chemical Industry.
