Boc-Gly-Gly-Phe-Gly-OH TFA is a self-assembly of N-protected and C-protected tetrapeptides and is a protease cleaved connector for antibody-drug binding (ADC).

Peptide fragment corresponding to residues 1 - 40 of Nogo-66, the domain of the myelin protein Nogo that inhibits axonal outgrowth. Acts as a competitive antagonist at the Nogo-66 receptor (NgR); blocks Nogo-66- and CNS myelin-induced inhibition of axonal growth, but does not reduce myelin-associated glycoprotein (MAG) inhibition of neurite outgrowth in vitro. Promotes regeneration of hemisected spinal axons and locomotor recovery following spinal injury in vivo.

Guattegaumerine is a bisbenzylisoquinoline alkaloid?with antimitotic, cytotoxic and neuroprotective activities.
