Semax peptide targets the μ opioid receptor gene Oprm1 to promote deubiquitination and functional recovery after spinal cord injury in female mice.

British journal of pharmacology 2025

Given the key roles of LMP and ubiquitination in SCI pathophysiology, this study investigated how Semax could modulate these pathways to affect functional recovery following SCI. Network pharmacology and docking revealed the μ-opioid receptor as a Semax target.

Semax, a Copper Chelator Peptide, Decreases the Cu(II)-Catalyzed ROS Production and Cytotoxicity of aβ by Metal Ion Stripping and Redox Silencing.

Bioinorganic chemistry and applications 2025

Alzheimer's disease (AD) is the most common neurodegenerative disorder associated with cognitive decline and loss of memory. It is postulated that the generation of reactive oxygen species (ROS) in Fenton-like reaction connected with Cu(II)/Cu(I) redox cycling of the Cu(II)-aβ complex can play a key role in the molecular mechanism of neurotoxicity in AD.

Synthetic corticotropins and the GABA-receptor system: Direct and delayed effects.

Chemical biology & drug design 2023

The molecular mechanism underlying the biological activity of such peptides is partly based on allosteric modulation of various receptors. We analyzed the ability of some biologically active synthetic corticotropins (ACTH(4-7)PGP, ACTH(6-9)PGP, ACTH(7-10)PGP), and glyproline PGPL to affect the GABA-receptor system of rat brain.

Brain Protein Expression Profile Confirms the Protective Effect of the ACTHPGP Peptide (Semax) in a Rat Model of Cerebral Ischemia-Reperfusion.

International journal of molecular sciences 2021

Previously, studies of the molecular mechanisms underlying the actions of Semax using models of cerebral ischemia in rats showed that the peptide enhanced the transcription of neurotrophins and their receptors and modulated the expression of genes involved in the immune response. At 24 h after tMCAO, we observed the upregulation of active CREB in subcortical structures, including the focus of the ischemic damage; downregulation of MMP-9 and c-Fos in the adjacent frontoparietal cortex; and downregulation of active JNK in both tissues under the action of Semax.

Novel Insights into the Protective Properties of ACTHPGP (Semax) Peptide at the Transcriptome Level Following Cerebral Ischaemia-Reperfusion in Rats.

Genes 2020

However, its molecular mechanisms of action within the brain are not yet fully understood. Therefore, the neuroprotective action of Semax may be associated with a compensation of mRNA expression patterns that are disrupted during ischaemia-reperfusion conditions.

Semax, an analog of ACTH, regulates expression of immune response genes during ischemic brain injury in rats.

Molecular genetics and genomics : MGG 2017

To build the effective strategies for stroke treatment it is necessary to understand the neuroprotective mechanisms that are able to prevent the ischemic injury. However, the molecular mechanisms underlying its neuroprotection and participation of PGP in them are still needed to be clarified.

Frequently Asked Questions

Essential information about our research-grade peptides and quality standards.

Peptides are short chains of amino acids linked by peptide bonds, typically consisting of 2-50 amino acids. They serve as the building blocks of proteins and play crucial roles in biological processes.

Research peptides are synthesized versions of naturally occurring peptides, manufactured to precise specifications for use in scientific studies.

Key characteristics: High purity (≥99%), lyophilized form for stability, accompanied by Certificates of Analysis (COA), and manufactured under strict quality control protocols.

Peptide purity refers to the percentage of the target peptide present in a sample, measured via High-Performance Liquid Chromatography (HPLC).

Our Standard: All our research peptides maintain ≥99% purity, verified by third-party laboratory testing and documented in our Certificates of Analysis.

Higher purity is critical for research because impurities can interfere with experimental results and compromise the reproducibility of studies.

All products are supplied in lyophilized powder form within sterile, sealed vials. This format provides:

  • Maximum stability: Extended shelf life compared to liquid solutions
  • Precise measurement: Researchers can work with desired quantities
  • Contamination protection: Sealed vials prevent environmental exposure
  • Shipping durability: Powder form is more stable during transit

Lyophilized peptides:

  • Store at -20°C for long-term storage (up to 24 months)
  • Store at 2-8°C (refrigerated) for short-term storage (up to 3 months)
  • Keep away from light, moisture, and repeated temperature fluctuations

We supply research-grade peptides to:

  • Academic and university research laboratories
  • Pharmaceutical and biotechnology companies
  • Independent research institutions
  • Licensed professionals conducting legitimate scientific research

We maintain rigorous quality control through a multi-step verification process:

  • HPLC Analysis: Every batch tested to verify ≥99% purity
  • Mass Spectrometry: Molecular weight confirmation for peptide identity
  • Third-Party Testing: Independent laboratory verification
  • Sterility Protocols: Aseptic handling and packaging procedures
  • Batch Documentation: Complete traceability from synthesis to delivery

"Research Use Only" (RUO) is a classification indicating that a product is intended exclusively for laboratory research and experimental investigation.
