Dihexa is a peptide variant derived from

angiotensin IV which has been found to potently

improve cognitive function in animal models of

disease such as Alzheimer’s. Angiotensin IV is a

derivative of the potent vasoconstrictor

angiotensin II and has been shown to enhance

acquisition, consolidation, and recall of learning

and memory in animal models when

administered centrally or peripherally. In an assay

of neurotrophic activity, Dihexa was found to

be seven orders of magnitude more potent than

BDNF. It could possibly help in the repair of the

brain and nerves in neurological disease.
