Dihexa
Mechanism of action
What Dihexa does in the body — step by step.
Dihexa is a small angiotensin IV-derived peptide analog modified for improved stability and membrane permeability.
In preclinical work it is linked to hepatocyte growth factor (HGF) and its receptor c-Met and is said to promote synapse formation (synaptogenesis).
It has been investigated in the context of learning and memory performance in animal models.
