Dihexa
Target: HGF/c-Met agonist
Angiotensin IV-derived research compound studied for synaptogenesis via the HGF/c-Met pathway. Preclinical and in-vitro only — no human trials, and the foundational mechanism papers were retracted in 2025.
Selank
Target: GABAergic / tuftsin analog
Selank is a synthetic neuropeptide derived from tuftsin with anxiolytic and nootropic properties. Developed in Russia for anxiety and cognitive enhancement. Studied for mood regulation, memory, and immune modulation without sedative effects.
Semax
Target: BDNF expression / melanocortin modulation
Semax is a synthetic peptide derived from ACTH (4-10) with neuroprotective and cognitive-enhancing properties. Developed in Russia for stroke recovery and cognitive disorders. Studied for memory, focus, neuroplasticity, and BDNF stimulation.
