What it is
N-Acetyl Semax (10mg) is supplied as a lyophilized reference compound for investigators in neuropeptides & cognitive research research. N-terminally acetylated analog of Semax (ACTH 4-10 analog) engineered for enhanced enzymatic stability. Investigated for nootropic and neurotrophic endpoints in preclinical models.
Within published references, the compound is most often interrogated alongside controls that match its delivery vehicle and reconstitution buffer, with attention to lot-to-lot purity and identity verification before use in any quantitative assay.
Research applications
Documented research applications for N-Acetyl Semax span several preclinical domains. The bullets below summarize commonly cited research questions; they do not constitute claims regarding human use, therapeutic effect, or any clinical outcome.
- Stabilized melanocortin-pathway pharmacology — preclinical assay endpoints and pathway-specific readouts.
- Bdnf/ngf expression — preclinical assay endpoints and pathway-specific readouts.
- Cognitive-research endpoints — preclinical assay endpoints and pathway-specific readouts.
- Comparative pharmacology versus the related research compounds listed below, in matched-vehicle preclinical models.
- Lot-to-lot reproducibility evaluations using HPLC, ESI-MS, and orthogonal functional assays.
Common research focus areas include Stabilized melanocortin-pathway pharmacology; BDNF/NGF expression; cognitive-research endpoints. Investigators routinely use N-Acetyl Semax as a probe for these pathways and as a reference compound in comparative pharmacology against the related research summaries linked at the bottom of this page.
Quality specifications
Reference-grade N-Acetyl Semax is characterized at minimum by reverse-phase HPLC purity (≥98% by HPLC), electrospray-ionization mass spectrometry confirming the expected monoisotopic mass, and quantitative amino-acid analysis where applicable. Cell-culture-grade lots additionally include endotoxin testing by Limulus amebocyte lysate (LAL) assay and bioburden screening. Each lot ships with a Certificate of Analysis itemizing purity, identity, residual solvents, water content (Karl Fischer), and counter-ion content where relevant.
Investigators working with new lots should request raw chromatograms and mass spectra prior to incorporating material into published work, and should validate ELISA or activity-assay readouts against orthogonal mass-spectrometric or functional methods.
Stability & handling
Lyophilized; reconstitute with bacteriostatic water; refrigerate aliquots. Working aliquots in active use are typically held at 2–8 °C for no more than 14 days, and freeze–thaw cycles should be minimized and documented in published methods. Storage history materially affects published phenotype magnitude and should be reported alongside dose and vehicle in any paper using this material.
