Semax is a synthetic polypeptide analog derived from the adrenocorticotropic hormone (ACTH) fragment 4–7, a peptide sequence associated with hormones produced by the anterior pituitary gland. Research literature indicates that this fragment does not exhibit the classical hormonal activity of ACTH, but has been investigated for its central nervous system related signaling properties in experimental models.
Naturally occurring peptides may exhibit limited stability due to rapid enzymatic degradation in biological environments such as gastrointestinal and cerebrospinal fluids. To address this, researchers have developed synthetic peptide analogsdesigned to retain biological relevance while offering improved structural stability. Semax is one such derivative, engineered to extend the Met–Glu–His–Phe sequence with a Pro–Gly–Pro (PGP) motif at the C-terminal region.
In laboratory research contexts, this structural modification has been examined for its influence on peptide stability, lipophilicity, and transport characteristics across experimental blood brain barrier models. Studies have also evaluated the impact of N-terminal acetylation on Semax, with findings suggesting increased resistance to enzymatic degradation and altered persistence in experimental systems.

Overview
Synthetically developed Semax has been extensively investigated in laboratory research for its mechanistic propertiesand structural stability. Scientific studies have examined its interaction with enzymatic systems involved in neuropeptide degradation, including enzymes associated with the breakdown of enkephalins, which are endogenous neurotransmitters studied for their role in nociception and stress related signaling pathways.
In experimental research models, modulation of enkephalin activity has been explored for its downstream influence on interconnected neurotransmitter systems. Due to the complex relationship between the opioid system and neurotransmitters such as dopamine and serotonin, researchers investigate Semax for its potential role in neurotransmitter release dynamics, receptor activity, and intracellular signal transduction pathways. These interactions represent an active and evolving area of neurochemical research.
Beyond enkephalin related pathways, Semax has also been evaluated for its interaction with other peptide degrading secreted enzymes in controlled laboratory environments. Additional studies have examined its association with dopaminergic signaling and neurotrophic factor pathways, including research exploring its relationship with brain derived neurotrophic factor (BDNF) expression under experimental conditions.
Further research has investigated Semax for its potential involvement in gene expression pathways related to immune signaling. Experimental findings have examined its influence on genes associated with immune cell regulation, cellular mobility, and the expression of chemokines and immunoglobulin related factors, which are relevant to vascular and immune system research models.
