These proteins are challenging targets for rational ligand discovery or drug design because they are highly dynamic and fluctuate through a diverse set of conformations, frustrating structure-based approaches. This dissertation describes the unique properties of disordered proteins that challenge ligand design strategies, then details methodologies designed to address these challenges. Chapter 2 details the in silico and in vitro methods used to identify and validate ligands of the disordered protein tau. Chapter 3 then further examines these compounds and how they interact with tau, as well as utilizing analogous compounds to understand the structure/function relationships that dictate their activity. Chapter 4 illustrates the adaptability of these approaches by utilizing similar methodologies to identify ligands of a different disordered protein system, phenol soluble modulins.application/pdfen-USnoneDisordered ProteinDrug DiscoveryMolecular DockingMolecular DynamicsPharmaceutical sciencesBiophysicsMedicinal chemistryThesis
