Semax (CAS No.: 80714-61-0) is a synthetic regulatory peptide composed of eight components and is a classic nutritional protective peptide commonly used in systems research. This product is a white lyophilized powder with an HPLC purity ≥98%, exhibiting excellent water solubility and stable physicochemical properties. It should be stored at -20℃ in a sealed, light-protected container and is suitable for long-term scientific research and various in vitro and in vivo model studies.

The core research mechanism of Semax lies in **upregulating the expression of brain-derived trophic factor (BDNF) and nerve growth factor (NGF)**, regulating hippocampal synaptic plasticity, making it a core raw material for research on cognitive function, repair, and brain injury mechanisms. Numerous animal and cell experiments have confirmed that Semax can significantly increase BDNF levels, promote cell survival and repair, inhibit oxidative stress and free radical accumulation, reduce cell apoptosis rate, and has a significant protective effect against cell damage caused by ischemia, hypoxia, and oxidative damage.

In neurotransmitter regulation studies, Semax can modulate the activity of the cholinergic, dopaminergic, and serotonergic systems, inhibit acetylcholinesterase activity, and stabilize central conduction balance. It is widely used in pharmacological studies of learning and memory mechanisms, attention regulation, central homeostasis, and emotional stress models. Simultaneously, it can block the overactivation of NMDA receptors, reduce calcium ion influx, and mitigate toxicity, making it an ideal candidate drug for basic research in areas such as cerebral ischemia-reperfusion injury, degenerative diseases, and repair.

However, it is important to clarify that most efficacy data for Semax comes from in vitro cell and animal models. Despite abundant literature, large-sample human clinical data are limited and should not be interpreted as therapeutic, anti-aging, or cognitive-enhancing effects. Its effects are dose-dependent, and data will vary depending on the route of administration and experimental model. Strict gradient control is crucial in scientific experiments.

In conclusion, Semax possesses stable protective effects, upregulation of nutritional factors, and cognitive regulatory activity, making it an indispensable high-quality research peptide in the fields of science, brain injury pharmacology, and degenerative disease research.
