ACPd

ACPD is an acronym used in different contexts, but in scientific literature it most commonly refers to the chemical compound 1-aminocyclopentane-1,3-dicarboxylic acid. This molecule is a non-selective agonist of metabotropic glutamate receptors (mGluRs) and is widely used as a pharmacological tool to activate these receptors in neuroscience research. Researchers employ ACPD to study glutamatergic signaling, synaptic transmission, and plasticity in brain tissue, neuronal cultures, and brain slices. While it helps illuminate the roles of mGluRs in learning, memory, and neurophysiology, ACPD is typically used as a research reagent rather than a therapeutic agent, due to its broad activity across receptor subtypes and potential for widespread neuronal effects.

Beyond this primary meaning, ACPD functions as an acronym in various other fields to denote different organizations, programs, or standards. The intended reference depends on context, such as the field, country, or accompanying terminology. Because there is no single universally dominant alternate meaning, readers should rely on contextual clues to determine which ACPD is being referenced.
