Description
Semax is a synthetic heptapeptide on the ACTH(4-10) sequence with the sequence Met-Glu-His-Phe-Pro-Gly-Pro, molecular formula C₃₇H₅₁N₉O₁₀S, a molecular weight of approximately 813.97 Da, and CAS number 80714-61-0. The C-terminal Pro-Gly-Pro extension enhances peptidase resistance (aminopeptidase and carboxypeptidase) and in-vitro stability.
In laboratory research, Semax is utilized in melanocortin receptor (MC4R, MC5R) interaction studies (where it shows partial-binding/displacement behavior in research models), BDNF expression-regulation experiments (1.4-fold increase, 1.6-fold TrkB phosphorylation in hippocampal models), nerve growth factor (NGF) pathway investigations, enkephalinase inhibition assays (IC₅₀ ~10 μM), dopaminergic and serotonergic neurotransmission studies, hippocampal LTP (long-term potentiation) electrophysiology, and CREB phosphorylation signaling research.
Supplied as a lyophilized powder with ≥99% purity verified by HPLC. For storage and handling conditions, refer to the Certificate of Analysis provided with each lot. This product is intended strictly for laboratory research use only (RUO) and is not for human consumption, therapeutic use, or any diagnostic purposes.
