Semax

Semax is investigated for neurotrophic signaling, including BDNF and TrkB. These pathways are relevant to neuronal adaptation; the cited preclinical findings do not establish better human memory or concentration.

Preclinical evidence

A rat hippocampus study reported changes in BDNF and TrkB signaling and performance in a conditioned behavioral task after Semax. BDNF is involved in neuronal adaptation. These observations are a basis for mechanistic research; they do not establish a reliable improvement in human memory, attention or recovery after stroke.
