- Pinealon
- 346 Da
- Direct passive diffusion + EAAT transport
- Binds DNA promoter regions; upregulates BDNF, NGF
- Cognitive decline, synaptic repair, neuroprotection
- Best choice for CNS-targeted studies requiring non-invasive delivery and gene-level modulation
- Semax
- 813 Da
- Limited (requires intranasal administration)
- BDNF upregulation via TrkB receptor
- Cognitive enhancement, stroke recovery
- Effective but delivery route limits systemic research applications
- Cerebrolysin
- ~10,000 Da (peptide mixture)
- Does not cross (requires IV administration)
- Mimics neurotrophic factors
- Post-stroke rehabilitation, dementia trials
- Clinical tool for acute intervention; impractical for preventative research
- Noopept
- 318 Da
- Crosses via prodrug metabolism
- Modulates AMPA and NMDA receptors
- Acute cognitive performance
- Fast-acting but no structural neuroprotection; tolerance develops
- P21 (CNTF fragment)
- 2,500 Da
- Does not cross (requires intrathecal injection)
- Ciliary neurotrophic factor mimetic
- Motor neuron disease, ALS trials
- Potent but invasive delivery limits use
