PIPE 3297 dihydrochloride New

Product Description

PIPE 3297 dihydrochloride is a potent and selective κ opioid receptor (KOR) agonist. It potently activates G-protein signaling (GTPγS EC₅₀ = 1.1 nM, 91% E_max). It displays 40- and 600- fold selectivity over MOR and DOR respectively. PIPE 3297 dihydrochloride induces differentiation of oligodendrocyte progenitor cells (OPC) in vitro and in vivo, leading to significant increase of mature oligodendrocytes (OL) in healthy mice and inducing myelination. It also reduces disease score in mouse experimental autoimmune encephalomyelitis (EAE) model. Exhibits low β-arrestin2 recruitment activity, avoding the sedating effects typically associated to other KOR agonists employed in demyelinating diseases. Brain penetrant, leads to 90% occupancy in CNS in vivo (mouse).
