Davunetide vs N-Acetyl Semax

Stabilizes microtubules by interacting with tubulin and microtubule-associated proteins. Activates SIRT1, reduces amyloid-β toxicity, and enhances synaptic plasticity. Protects against tau hyperphosphorylation.

An 8-amino acid neuroprotective peptide derived from Activity-Dependent Neuroprotective Protein (ADNP). Among the most potent neuroprotective agents identified in preclinical models. Studied for Alzheimer's disease, schizophrenia, and traumatic brain injury.

Same ACTH(4-7) core as Semax, but structural modifications resist peptidase degradation. Enhances BDNF expression, supports dopaminergic and serotonergic neurotransmission, and modulates NMDA receptor activity.

An acetylated and amidated derivative of Semax with enhanced enzymatic stability and prolonged activity. N-terminal acetylation and C-terminal amidation protect the peptide from degradation, extending its nootropic and neuroprotective effects versus base Semax.
