- Cerebrolysin
- Multi-peptide Trk receptor agonism
- BDNF, NGF, CNTF mimicry via TrkA/TrkB activation
- Stroke, TBI, neurodegenerative models
- 2–8°C, protect from light
- Broadest neurotrophic coverage with four decades of safety data. Preferred for multi-pathway neuroprotection models
- Dihexa
- Hepatocyte growth factor (HGF) pathway modulation
- Met receptor activation, synaptic density increase
- Cognitive enhancement, dementia models
- −20°C before reconstitution, 2–8°C after
- Seven-fold more potent than BDNF in hippocampal synapse formation but limited long-term safety data. Best for short-term synaptic plasticity studies
- P21 (CNTF fragment)
- CNTF receptor agonism
- JAK/STAT pathway, neuronal differentiation
- Motor neuron survival, ALS models
- 2–8°C, reconstitute fresh
- Highly selective for CNTF-mediated survival signaling. Ideal when isolating CNTF effects without BDNF/NGF crosstalk
- Semax
- ACTH(4-10) analog, neurotrophic gene expression
- BDNF upregulation via MAPK pathway
- Cognitive performance, stress resilience
- Room temperature stable (lyophilized), 2–8°C after reconstitution
- Indirect neurotrophic activity through gene expression rather than receptor mimicry. Lower acute potency but convenient intranasal delivery for behavioral studies
- This table highlights the mechanistic distinctions that determine which neurotrophic approach fits specific research questions. Cerebrolysin's multi-peptide composition gives it the broadest coverage but makes it impossible to isolate which specific pathway is driving observed effects. Dihexa offers far greater potency for synaptic density studies but lacks the decades of safety profiling that cerebrolysin has accumulated. P21 provides mechanistic specificity when you need to isolate CNTF signaling without confounding BDNF effects. Semax works through indirect upregulation rather than receptor mimicry, making it useful when you want sustained low-level neurotrophic support without supraphysiological receptor activation.
