proteoglycan

Copper tripeptide (GHK-Cu) is a naturally occurring copper complex of the tripeptide glycyl-L-histidyl-L-lysine, with a strong affinity for copper(II). First isolated from human plasma, it is also found in saliva and urine.

PTPσ Inhibitor ISP is a compound that binds to recombinant human PTPs, thereby inhibiting PTPσ signaling. It has the capability to penetrate membranes and counteract the inhibitory effects of chondroitin sulfate proteoglycan (CSPG) on axonal sprouting in spinal cord injury models. Additionally, it fosters remyelination in lysolecithin (LPC)-induced demyelinated spinal cords and supports the migration and maturation of oligodendrocyte progenitor cells (OPCs), enhancing remyelination and functional recovery in Multiple Sclerosis (MS) animal models [1] [2].
