Semax

Semax is a synthetic heptapeptide analog of ACTH(4‑10) notable for its exceptional stability and brain‑targeting properties. In laboratory investigations, it has attracted interest as a neurotrophic and neuroprotective signaling agent: Semax resists degradation by peptidases, enabling it to penetrate the blood–brain barrier and engage melanocortin receptors. There, it upregulates BDNF and NGF expression, enhances cerebral microcirculation, and modulates monoaminergic neurotransmission to support synaptic plasticity, cognitive resilience, and neuronal survival under stress or ischemic challenge. Its unique combination of stability, receptor‑mediated action, and multifaceted support of neurotrophic pathways makes it an invaluable tool for researchers modeling neurodegeneration, cognitive fatigue, and recovery from brain injury.
