Semax

Semax, a synthetic analog of ACTH (4-10) with the sequence Met-Glu-His-Phe-Pro-Gly-Pro, is a heptapeptide characterized by its stability and enzymatic resistance. Its molecular structure, C37H51N9O10S, and molecular weight of 813.92 g/mol, indicate a relatively small peptide suitable for various biochemical analyses. Research into Semax has explored its interactions within neuronal pathways. Historically, the development of Semax emerged from studies on ACTH fragments and their neuroregulatory properties, with modifications aimed at enhancing stability and bioavailability for research purposes. Early investigations focused on its observed effects on brain-derived neurotrophic factor (BDNF) expression and its interaction with dopaminergic and serotonergic systems in animal models. In laboratory research, Semax is utilized to investigate mechanisms related to neuroprotection, neuronal plasticity, and cognitive function. Studies often involve examining its influence on gene expression, protein synthesis, and neurotransmitter levels in isolated cell cultures or animal models. Its unique structure allows for targeted exploration of peptide-receptor interactions within the central nervous system.
