Heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro, an ACTH(4-7) analog extended with Pro-Gly-Pro
Semax is a synthetic heptapeptide, Met-Glu-His-Phe-Pro-Gly-Pro. Its first four residues are the 4-7 fragment of corticotropin (ACTH), and a C-terminal Pro-Gly-Pro tripeptide was added to slow enzymatic breakdown. It was developed in the 1980s at the Institute of Molecular Genetics of the Russian Academy of Sciences in Moscow. It is a linear, unmodified peptide with a free N-terminus and a free C-terminal acid, supplied as synthetic material.
Semax belongs to the family of synthetic ACTH-fragment analogs. Published work spans peptide degradation chemistry in serum and blood with peptidase inhibitors, metal-ion coordination chemistry, and analog design around the N-terminus. The references below are limited to degradation and coordination-chemistry papers.
