Description

Product Overview

Semax Peptide is a synthetic analog of the ACTH(4–10) fragment consisting of the amino acid sequence Met-Glu-His-Phe-Pro-Gly-Pro (MEHFPGP). Originally developed for scientific investigation of neurobiological signaling mechanisms, Semax has become one of the most extensively studied research peptides in experimental neuroscience due to its broad influence on neurotrophic pathways, neurotransmitter systems, and intracellular signaling networks.

Published laboratory research has demonstrated that Semax Peptide interacts with multiple molecular pathways involved in neuronal communication, including regulation of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), cyclic AMP-responsive transcription factors, and several kinase-mediated signaling cascades. Investigators have also examined its effects on dopamine, serotonin, and glutamatergic neurotransmission in controlled experimental models.

The peptide’s favorable stability and well-characterized molecular profile make it an important research reagent for studies involving neuronal differentiation, synaptic plasticity, peptide transport, oxidative stress responses, and gene regulation. Its lack of classical hormonal activity further allows researchers to evaluate neurobiological signaling independently of endocrine effects associated with native ACTH.

Manufactured to rigorous research standards, Semax Peptide is supplied as a high-purity lyophilized powder suitable for advanced molecular biology, pharmacology, biotechnology, and neuroscience research laboratories.

Product Specifications

Mechanism of Action

Semax Peptide is a synthetic heptapeptide derived from the adrenocorticotropic hormone fragment ACTH(4–10). Unlike the parent hormone, Semax does not exhibit significant melanocortin-mediated endocrine activity, allowing researchers to investigate its molecular actions independently of classical ACTH signaling. Its established biochemical profile has made it an important experimental peptide in molecular neuroscience, neuropharmacology, and cellular signaling research.

Published laboratory investigations indicate that Semax Peptide modulates multiple intracellular signaling pathways associated with neuronal communication and adaptive cellular responses. One of the most extensively studied mechanisms involves regulation of brain-derived neurotrophic factor (BDNF), a neurotrophin that activates tropomyosin receptor kinase B (TrkB). Activation of TrkB initiates intracellular signaling through phosphoinositide 3-kinase (PI3K)/Akt, mitogen-activated protein kinase (MAPK/ERK), and phospholipase C-γ pathways, influencing transcriptional activity, protein phosphorylation, and neuronal signaling processes.

Experimental studies have also demonstrated modulation of cyclic AMP response element-binding protein (CREB), a transcription factor involved in regulation of genes associated with neuronal development, synaptic communication, and intracellular adaptation. Additional investigations suggest that Semax influences expression of nerve growth factor (NGF), immediate early genes, and proteins associated with synaptic plasticity under controlled laboratory conditions.

Beyond neurotrophic signaling, Semax Peptide has been examined for its effects on neurotransmitter systems, including dopaminergic, serotonergic, glutamatergic, and cholinergic pathways. These studies explore how peptide-mediated signaling influences neurotransmitter synthesis, release, receptor responsiveness, and neuronal network communication in experimental models.

Research has further investigated Semax in relation to oxidative stress regulation, mitochondrial function, antioxidant enzyme activity, and inflammatory signaling pathways. Laboratory evidence suggests modulation of intracellular kinase activity, reactive oxygen species homeostasis, and transcriptional networks involved in cellular stress responses, although these findings continue to be explored in mechanistic studies.

Because of its defined amino acid sequence, favorable stability, and extensive characterization within peer-reviewed scientific literature, Semax Peptide remains an important molecular tool for investigating peptide chemistry, neurotrophic factor regulation, receptor pharmacology, gene expression, and intracellular signaling mechanisms across a broad range of in vitro and preclinical research applications.
