Abstract: Imaging agents that can bind to ghrelin O-acyltransferase (GOAT) without binding to the ghrelin receptor (GHS-R1a). The imaging agents comprise a base structure for selective binding to GOAT that is coupled via an amino acid linker to a chemical group to enable imaging such as a fluorescent label, radioactive tracer, or metal chelator. For example, the imaging agent may comprise a ghrelin substrate mimetic inhibitor incorporating an unmodified 2,3-diaminopropanoic acid (Dap) group at the site analogous to serine 3. These agents enable specific detection and imaging of GOAT versus the GHS-R1a receptor in a variety of biological contexts.
