What is dihexa?
Another compound in this catalogue that is not a peptide, though it was derived from one. It is one of the few here available as a capsule, and the reason for that is worth understanding.
Derived from a peptide, no longer one
Dihexa came out of work on angiotensin IV, a fragment of the angiotensin system with activity in the brain that is separate from the blood pressure role the system is known for. Researchers modified that starting point substantially, aiming for something that would survive metabolism and reach the brain.
What emerged is best described as a small molecule with peptide ancestry. Calling it a peptide is convenient shorthand and it is not accurate, which matters when you are looking for the right literature.
Hepatocyte growth factor, in the brain
The proposed mechanism involves hepatocyte growth factor and its receptor c-Met. Despite the name, that pair is not confined to the liver: it has documented roles in the nervous system, including in synapse formation.
Research has looked at synaptic connectivity and at behavioural measures in animal models of cognitive impairment. The work comes largely from the group that developed the compound, and independent replication is limited.

Why it survives the oral route
The modifications that made dihexa metabolically stable are also what make an oral format worth considering. A peptide of similar size would not survive the digestive tract; this molecule was designed not to be one.
Very little in this catalogue qualifies. A compound earns a place in the capsule list one of two ways: it resists degradation unusually well, or its target sits inside the gut itself. Dihexa belongs to the first group.
