SEMAX

Compound Overview

Semax is a synthetic heptapeptide derived from the N-terminal fragment of adrenocorticotropic hormone (ACTH 4–10) with the addition of a C-terminal Pro-Gly-Pro (PGP) sequence to improve enzymatic stability and prolong biological activity. Unlike the parent ACTH peptide, Semax does not exhibit hormonal activity associated with adrenal corticosteroid production, making it a valuable investigational peptide for studying neurobiology, peptide pharmacology, and molecular signaling.

Researchers continue to investigate Semax in experimental models to better understand its interactions with neurotrophic signaling pathways, neuropeptide regulation, gene expression, and central nervous system physiology. Preclinical studies have examined its influence on brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), neurotransmitter systems, and intracellular signaling cascades involved in neuronal function and peptide-mediated cellular communication.

As an investigational peptide, Semax supports laboratory research involving molecular neuroscience, neuroendocrine physiology, peptide engineering, pharmacokinetics, and structure-activity relationships.

Laboratory Handling

Store refrigerated immediately upon receipt to preserve peptide stability. For extended laboratory storage, freezing at −20°C or below is recommended. Protect the lyophilized peptide from moisture, excessive heat, and direct light. Avoid repeated freeze-thaw cycles following reconstitution, as these may reduce peptide stability. Allow the vial to equilibrate to room temperature before opening to minimize condensation, and always use sterile laboratory equipment together with appropriate aseptic laboratory techniques. This product is intended for use only by qualified research personnel operating in controlled laboratory environments.
