What Is This?
Semax is a small peptide based on a piece of ACTH (a natural hormone), modified to be more stable in solution and culture. It is heavily studied for increasing BDNF and other growth factors that help neurons survive and form new connections - especially when brain cells face oxidative stress, low oxygen, or excitotoxic challenge in vitro.
What Do Researchers Study?
Researchers use Semax to measure brain growth factor levels (BDNF, NGF, GDNF), test neuron survival in low-oxygen culture conditions, and study how well neurons form new connections and dendritic branches. Hippocampal and cortical neuron cultures are the most common models.
Common Research Uses
- BDNF and neurotrophin level measurements in neuronal cultures
- Low-oxygen and oxidative stress protection tests in brain cells
- Synaptic connection, spine density, and branching studies
- Excitotoxicity and glutamate-challenge protection assays
- Comparative studies alongside Selank in CNS peptide research
What the Science Is Looking At
- Linked to higher BDNF, NGF, and GDNF levels in neuronal cultures - key factors for neuron health
- Helps brain cells survive low-oxygen and oxidative challenge in culture
- Supports markers of new synaptic connections in hippocampal cells
- Shows protective effects against excitotoxicity and free-radical damage in neuron studies
- Well-documented in Russian and international CNS peptide literature as a reference compound
How It Works - In Plain English
Growth Factor Boost
Associated with increased production of BDNF and related neurotrophins that help neurons grow and stay healthy. Labs often measure these proteins by ELISA or Western blot after treatment.
Protection Under Stress
In oxygen-deprivation and oxidative-stress cultures, treated neurons show better survival and lower apoptosis markers compared to untreated controls.
Better Connections
Increases synaptic proteins and dendritic spine markers - signs of improved neuron communication and plasticity in culture.
ACTH-Derived Stability
Built from the ACTH(4-10) sequence with modifications that improve peptide stability, making it practical for multi-day neuronal culture experiments.
