What is on file, and how it is handled

Every figure below is transcribed from the paperwork for this compound.

What is Selank?

The first four residues are the tuftsin sequence itself; the Pro-Gly-Pro extension on the C-terminus slows enzymatic breakdown without changing what the tuftsin portion binds. The same stabilising trick is used in Semax. Studied in anxiolytic and immunomodulatory models.
