Neuropeptides
Neuropeptides for Research: Selank, Semax, DSIP, Orexin and More
Peptides studied in neurotransmission and stress axis models.
Neuropeptides are short amino acid chains that act as messengers and modulators in the nervous system. This category brings together 15 compounds studied in neuroscience and neuroendocrinology. Every product is supplied as a research reagent (Research Use Only).
Selank and Semax, and their analogues
Selank is a synthetic analogue of tuftsin, a natural tetrapeptide from immunoglobulin G. The added Pro-Gly-Pro sequence makes it a common subject in studies of how structure shapes activity.
Semax is a synthetic analogue of the ACTH 4-10 fragment. Studies in animal models have examined its influence on cognitive function and BDNF expression. Semax has also been studied clinically and is registered as a medicine in Russia.
N-Acetyl Selank Amidate, N-Acetyl Semax Amidate and Semax + Selank are also available.
Orexins, oxytocin and Kisspeptin-10
Orexin A (hypocretin 1) is a 33-amino-acid hypothalamic neuropeptide and an agonist of OX1R and OX2R. Orexin B (hypocretin 2) preferentially binds OX2R. Oxytocin, a pituitary nonapeptide, is a registered medicine and the subject of numerous clinical studies.
Kisspeptin-10 is a decapeptide fragment of kisspeptin that binds the KISS1R receptor. It is a key tool in research on the HPG axis.
Other compounds
DSIP is a nonapeptide from rabbit brain, studied in models of sleep-wake rhythm. Dihexa, an angiotensin IV derivative, is analysed in models of synaptic plasticity. P21 and Adamax carry an adamantyl group, and PE-22-28 is studied as a TREK-1 channel blocker. Cerebrolysin is a mixture of peptides from pig brain, studied in neurotrophic models. The literature describes its clinical studies and its registration in selected countries.
