BDNF Neurotrophic Signaling
N-Acetyl Semax is a terminally modified analog of Semax, itself a synthetic heptapeptide analog of adrenocorticotropin fragment 4-10. The common form carries an acetylated N-terminus and an amidated C-terminus, modifications studied for peptide stability. In published research on the parent peptide, Semax was shown to bind specifically and increase brain-derived neurotrophic factor (BDNF) protein levels in the rat basal forebrain (Dolotov et al, 2006, PMID 16635254).
A later study examined Semax and a derivative in an animal model of Alzheimer-type pathology (Radchenko et al, 2025, PMID 41479572). N-Acetyl Semax shares the ACTH(4-10) core sequence of Semax with acetyl and amide terminal modifications. For research purposes only.
