Endomorphin 2
Endomorphin 2 (CAS: 141801-26-5), a synthetic opioid peptide with the molecular formula C32H37N5O5 and a molecular weight of 571.67, mimics the action of endogenous opioid peptides. It is primarily utilised in scientific research as a tool to investigate opioid receptor pharmacology, particularly the mu-opioid receptor (OPRM1). Its applications extend to cell biology and neuroscience research, aiding in the study of pain pathways, addiction, and other central nervous system functions.

Opioid Receptor Research
Endomorphin 2 serves as a selective ligand for the mu-opioid receptor (OPRM1). It is instrumental in in vitro and in vivo studies to understand receptor binding kinetics, downstream signalling pathways, and the physiological effects of mu-opioid receptor activation.
Neuroscience and Pain Studies
This neuropeptide is employed to investigate the role of the endogenous opioid system in pain perception, analgesia, and other neurological processes. Researchers use it to explore mechanisms related to pain signalling and potential therapeutic targets.
Cell Biology and Signaling
As a bioactive small molecule, Endomorphin 2 can be used in cell-based assays to study cellular responses to opioid receptor activation. This aids in elucidating complex cell signaling cascades relevant to various physiological and pathological conditions.
