Primary research directions

What 7 of the most-cited and most recent Semax papers report, in their own authors’ terms. Each line links the paper it came from.

  • This narrative review of nine peptides studied in aging research groups Semax under neuroprotection and notes that the non-approved peptides showed promising preclinical but limited clinical evidence and lack long-term safety data and systematic validation.

    ReviewMavrych V 2026Frontiers in agingPMID 42021992

  • This overview of 15 years of semax research, an ACTH(4-10) analogue, describes reports that the peptide stimulated memory and attention, increased resistance to hypoxia and improved brain circulation in experimental animals and humans, with no negative side actions described in the reported cases.

    ReviewAsmarin IP 1997Zhurnal vysshei nervnoi deiatelnosti imeni I P PavlovaPMID 9173745

  • In rats with transient cerebral ischemia-reperfusion, RNA-Seq identified 394 genes differentially expressed with Semax versus saline; Semax was associated with suppressed inflammation-related genes and activated neurotransmission-related genes, which the authors suggest may relate to its neuroprotective action.

    RatsFilippenkov IB 2020GenesPMID 32580520

  • In rats with permanent focal brain ischemia, genome-wide analysis found that Semax predominantly enhanced expression of immune-related genes, notably those encoding immunoglobulins and chemokines, and altered vascular-system genes; the authors propose these as likely mechanisms of its neuroprotective effects.

    RatsMedvedeva EV 2014BMC genomicsPMID 24661604

  • In rats with permanent middle cerebral artery occlusion, Semax and its Pro-Gly-Pro fragment both activated transcription of neurotrophins and their receptors in the cortex, with Semax's effects described as selective to ischemic cortex and those of Pro-Gly-Pro as mainly unspecific.

    RatsDmitrieva VG 2010Cellular and molecular neurobiologyPMID 19633950

  • In the rat hippocampus, Semax was reported to increase BDNF protein, trkB phosphorylation and BDNF and trkB mRNA levels, and treated animals showed more conditioned avoidance reactions; the authors suggest Semax affects cognitive function via the hippocampal BDNF/trkB system.

    RatsDolotov OV 2006Brain researchPMID 16996037

  • In glial cell cultures from the basal forebrain of newborn rats, Semax rapidly increased mRNA levels of the neurotrophins BDNF and NGF, with the greatest increase observed shortly after exposure.

How these numbers were counted

  • PubMed search, run November 1, 2026: semax[tiab] re-run it. Study types add PubMed’s own filters (review, clinical trial, animals not humans).
  • Topics: MeSH major-topic headings counted across up to 400 of the matching records; headings for study set-up (species, sex, age) are left out.
  • Citations: NIH iCite citation counts for the same records.
  • ClinicalTrials.gov search: semax re-run it. Any phase, any status.

This page reports what has been published and what papers say they found, with each source linked. It gives no dosing or usage information, and nothing here is a reason to use Semax outside a laboratory.
