Procyclidine HCl

Procyclidine HCl (CAS No.: 1508-76-5) is a synthetic small molecule of the anticholinergic chemical class that is primarily categorized as a neuropharmacology research tool for interrogating cholinergic and glutamatergic signaling in central nervous system models, with established functional characterization as a muscarinic acetylcholine receptor antagonist and reported NMDA receptor antagonist like activity that supports mechanistic studies of receptor crosstalk, excitatory inhibitory balance, and circuit level neurotransmission relevant to movement disorder and seizure related experimental paradigms; in biomedical research workflows it is commonly used to probe cholinergic tone dependent phenotypes, to benchmark pathway modulation in receptor pharmacology assays, and to support exploratory drug discovery programs focused on ligand receptor interactions, target selectivity, and structure activity relationships, while in vitro potency is generally described in the nanomolar to micromolar range depending on assay format, receptor subtype context, and species background, and practical use spans cell based receptor signaling systems and animal model studies where concentration or dose selection is determined by specific protocol design, route of administration, and study objectives under appropriate laboratory safety and institutional research oversight.
