Research Mechanism Summary

N-Acetyl Semax Amidate (Ac-Met-Glu-His-Phe-Pro-Gly-Pro-NH₂) is a stabilized heptapeptide derived from the ACTH(4-7) fragment with a C-terminal Pro-Gly-Pro extension, N-terminal acetylation, and C-terminal amidation that protect against leucine aminopeptidase and carboxypeptidase degradation, respectively. The modifications are reported to extend plasma half-life by approximately 30 minutes over standard Semax and increase stability in brain tissue. Like Semax, it modulates melanocortin receptors (MC4/MC5), upregulates BDNF expression and TrkB receptor density, and modulates serotonin and dopamine turnover; preclinical studies indicate neuroprotective actions in ischemic conditions through angioprotective, antihypoxic, and anti-inflammatory mechanisms.
