What if neuroplasticity research targeted the HGF c Met pathway? Dihexa (PNB 0408) is an angiotensin IVderived peptide studied in preclinical models for its role in synaptogenesis and cognitive signaling mechanisms. Human data remains limited.

Martino, Arush Nakhre, Renee M. Demarest, David M. Devilbiss, 2025 Artificial human Met agonists based on macrocycle scaffolds Nature Communications Dihexa (also known as PNB 0408) is an experimental small molecule derived from angiotensin IV. It was engineered to cross the bloodbrain barrier and has shown synaptogenic effects in preclinical models.
