Semax Study Index

Semax (Met-Glu-His-Phe-Pro-Gly-Pro) is a synthetic heptapeptide analog of the adrenocorticotropic hormone fragment ACTH(4-7), developed in Soviet and Russian neuroscience research in the 1980s. Its primary documented mechanisms involve upregulation of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in CNS preclinical models, along with interactions with dopaminergic and serotonergic neurotransmitter systems that contribute to its documented effects on attention, memory, and cognitive performance in rodents. Semax has also been studied for neuroprotective properties in ischemic injury models where BDNF elevation is associated with reduced neuronal loss.

Research Questions

Common questions about Semax research context, mechanism, and procurement.

What is Semax and what is its research origin?+
Semax is a synthetic heptapeptide analog of the ACTH(4-7) fragment of adrenocorticotropic hormone, developed in Soviet and Russian neuroscience research in the 1980s. It was originally investigated as a cognitive-enhancing compound based on its structural relationship to the ACTH peptide known to affect learning and memory in animal models.
What does Semax research show about BDNF upregulation?+
Dolotov et al. (2006, Journal of Neurochemistry) documented Semax significantly increasing BDNF and NGF expression in rat cortex and hippocampus following administration. This neurotrophic factor upregulation is the primary proposed mechanism for both the neuroprotective and cognitive performance effects documented in rodent models.
Has Semax been studied in ischemic injury research?+
Gusev et al. (1997, Cerebrovascular Diseases) reported improved neurological outcome scores in acute ischemic stroke patients treated with Semax compared to controls. This limited clinical dataset is frequently cited alongside the broader rodent ischemia literature as context for the BDNF-mediated neuroprotective mechanism.
What dopaminergic research has been conducted on Semax?+
Agapova et al. (2007, Bulletin of Experimental Biology and Medicine) documented Semax demonstrating antidepressant-like effects in rodent forced swim and tail suspension models, with dopaminergic pathway modulation proposed as the mechanism. This extends the Semax research profile beyond cognition into monoamine system regulation relevant to mood-related preclinical models.
