Abstract
The binding of ecdysteroids and the bisacylhydrazine insecticide, tebufenozide, to recombinant ecdysone receptor ligand-binding domains from pest insects points to conserved and variable features of the receptor's ligand-binding pocket. Fluorophores conjugated to the terminus of the ecdysteroid alkyl chain have surprisingly little effect on receptor binding, permitting the development of a fluorescence polarization chemical library screen that has led to the discovery of a new class of ecdysone receptor ligands, the methylene lactams. X-ray structures of ecdysone receptor ligand-binding domains have allowed identification of the conserved and variable features within the binding pocket. The ..
