Research Comparison
Semax and Selank are both Russian-developed research neuropeptides, but they derive from different parent molecules. Semax is an ACTH(4-7) fragment studied mainly for neuroprotection and BDNF/NGF signaling, while Selank derives from the immunopeptide tuftsin and is studied mainly for tuftsin-receptor and serotonergic signaling.
| Attribute | Semax | Selank |
|---|---|---|
| Parent peptide | ACTH(4-7) | Tuftsin |
| Primary research focus | Neuroprotection, BDNF signaling | Tuftsin-receptor signaling |
| Shared mechanism | BDNF/NGF upregulation | BDNF modulation |
| Neurotransmitter studies | Dopamine, serotonin | Serotonin, GABA-related |
They are sometimes studied in parallel because both modulate BDNF, but they have distinct primary focuses — Semax for neuroprotection/BDNF signaling and Selank for tuftsin-receptor signaling.
