Semax
Nootropic peptide for cognitive enhancement
Semax is a synthetic heptapeptide analog derived from the corticotropin (ACTH) fragment ACTH(4-10). Originally developed in Russia, this compound exhibits potent nootropic and neuroprotective characteristics. It is classified as a selective cognitive enhancer due to its lack of effect on systemic hormone levels.
- •Enhances cognitive function in research models.
- •Improves memory consolidation and retrieval.
- •Demonstrates robust neuroprotection against ischemic stress.
- •Modulates brain-derived neurotrophic factor (BDNF) expression.
- •Investigated for potential anti-depressant and anxiolytic effects.
- •Supports neuronal survival under conditions of oxidative stress.
Semax functions primarily through interaction with specific brain receptors, notably melanocortin receptors (MCRs), particularly MC4 and MC5. Unlike the full ACTH molecule, Semax lacks peripheral steroidogenic activity. Its neurobiological effects are mediated by modulating the expression and activity of neurotrophins, such as BDNF, which is crucial for synaptic plasticity and neuronal health. Furthermore, Semax influences the metabolism of monoamines, including dopamine and serotonin, within the central nervous system, contributing to its cognitive and mood-regulating properties.
The primary scientific application of Semax lies in the investigation of cognitive enhancement and neuroprotection. It is widely used in preclinical models studying the mechanisms underlying memory formation, learning deficits, and recovery following neurological insults, such as stroke or global ischemia. Researchers utilize Semax to explore novel therapeutic strategies for neurodegenerative conditions and traumatic brain injury, focusing on its ability to stabilize neuronal membranes and mitigate excitotoxicity. Its selective action profile also makes it a valuable tool for studying the specific roles of melanocortin pathways in central nervous system function independent of pituitary-adrenal axis activation.
