Leu-enkephalin is an endogenous pentapeptide and potent agonist of the delta-opioid (Ki = 4.0 nM) and µ-opioid (Ki = 3.4 nM) receptors. It is widely used in neuroscience research to study pain modulation, receptor signaling, and neuropeptide function in both in vitro binding assays and in vivo behavioral models.
