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.

Dihexa is a synthetic hexapeptide analog of angiotensin IV with potent nootropic properties. Proposed to be 10 million times more potent than BDNF at promoting synaptic connectivity. Investigated for cognitive enhancement and neurodegenerative diseases.

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.
