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.

The often quoted HGF c Met signaling promotes the migration and proliferation of deer antler MSCs Scientific Reports HGF Signaling Pathway Sino Biological Signaling pathway of HGF c MET in cancers. Stimulation of c MET by HGF Download Scientific Diagram Dihexa is an experimental cognitive peptide that may help the brain build stronger connections between neurons instead of just temporarily boosting neurotransmitters like many nootropics do. It works through the HGF c Met pathway,
