Peptide Directory

Semax is a synthetic heptapeptide derived from ACTH(4-10) fragment, developed in Russia for neuroprotective and cognitive-enhancing applications. Research focuses on stroke recovery, cognitive function, and BDNF modulation.

Selank is a synthetic heptapeptide analog of tuftsin developed in Russia as an anxiolytic and nootropic. Shows both immunomodulatory and anxiolytic properties without sedation or dependence in research studies.

Cerebrolysin is a porcine brain-derived peptide preparation containing low-molecular-weight neuropeptides and free amino acids. Approved in many countries (not the US) for stroke, traumatic brain injury, and dementia. One of the most studied neuropeptide formulations.

DSIP is a naturally occurring neuropeptide first isolated from rabbit brain tissue. Research focuses on sleep induction, stress reduction, and neuroendocrine modulation. Shows complex, context-dependent effects.

PE-22-28 is a synthetic 7-amino-acid peptide derived from the spadin family, designed to inhibit the TREK-1 potassium channel. Research focuses on antidepressant-like effects and cognitive enhancement through BDNF-mediated neuroplasticity in preclinical models.

Pinealon is a synthetic tripeptide bioregulator (Glu-Asp-Arg) developed in Russia, targeting pineal gland and central nervous system function. Research focuses on sleep regulation, neuroprotection, and cognitive function in aging subjects.

Cortagen is a synthetic tetrapeptide bioregulator (Ala-Glu-Asp-Pro) developed at the St. Petersburg Institute of Bioregulation and Gerontology. Research focuses on normalizing cerebral cortex function, cognitive enhancement in aging, and neuroprotection.
