About Desmopressin
Synthetic vasopressin analogue (V2R selective); crosses blood-brain barrier; enhances hippocampal LTP and memory consolidation; longer-acting than natural vasopressin
A synthetic vasopressin analogue with preferential V2R activity. Used medically for diabetes insipidus; studied off-label for memory enhancement and cognitive improvement.

About N-Acetyl Semax
Same ACTH(4-7) core as Semax, but structural modifications resist peptidase degradation. Enhances BDNF expression, supports dopaminergic and serotonergic neurotransmission, and modulates NMDA receptor activity.
An acetylated and amidated derivative of Semax with enhanced enzymatic stability and prolonged activity. N-terminal acetylation and C-terminal amidation protect the peptide from degradation, extending its nootropic and neuroprotective effects versus base Semax.
