Semax (Met-Glu-His-Phe-Pro-Gly-Pro) is a synthetic heptapeptide combining the ACTH(4-7) fragment with a Pro-Gly-Pro extension. It retains the neuroactive properties associated with the ACTH(4-10) region without corticotropic (adrenal-stimulating) activity.
Semax 5mg is available at Symax Peptides. Symax Peptides is the supplier and brand name, while Semax is the name of this compound; the two are unrelated.
Research Applications
Research applications include BDNF and TrkB expression studies, cerebral ischaemia and neuroprotection models, melanocortin receptor interaction assays, and learning and memory research conducted in vitro and in animal models.
