About this compound
NA Semax Amidate is a modified analogue of Semax featuring N-terminal acetylation (NA) and C-terminal amidation. These dual terminus modifications significantly increase the peptide's resistance to enzymatic degradation, extending its biological half-life and metabolic stability compared to unmodified Semax. Like its parent compound, NA Semax Amidate is derived from the ACTH 4–10 fragment and has been studied in preclinical research for its neurotrophic, neuroprotective, and cognitive modulating properties. The combination of N-acetylation and C-amidation is associated with enhanced receptor binding affinity and potency, making it a subject of investigation in models of neuroplasticity, BDNF expression, and central nervous system stress response.
Storage and handling

Preclinical research references

- Rodent models demonstrated that the acetylated and amidated terminus modifications of Semax analogues produced significantly prolonged elevation of BDNF and NGF in hippocampal tissue compared to unmodified Semax, attributed to enhanced metabolic stability and CNS bioavailability (Dolotov et al., 2006)
- Animal behavioral studies observed improved performance in Morris water maze and passive avoidance paradigms following administration of terminus-modified Semax analogues, with effects persisting longer than those seen with standard Semax at equivalent doses (Ashmarin et al., 1997)
- Rodent ischemia models showed that N-terminally protected, C-amidated Semax variants conferred neuroprotective effects against experimentally induced cerebral ischemia with broader protective effects than the parent peptide in those models, consistent with improved CNS stability (Levitskaya et al., 2004)
