Dihexa
experimentalAn angiotensin IV analog with extraordinary potency for cognitive enhancement, reported to be millions of times more potent than BDNF.
Overview
Dihexa is a synthetic hexapeptide analog of angiotensin IV developed by researchers at Washington State University, led by Dr. Joseph Harding. It was designed to enhance hepatocyte growth factor (HGF) signaling through its receptor c-Met, which plays a critical role in synaptogenesis and neuronal connectivity.
In preclinical studies, Dihexa demonstrated cognitive enhancement at picomolar concentrations — approximately 10 million times more potent than BDNF at promoting new synapse formation. It has shown remarkable results in animal models of dementia, restoring cognitive function in aging rats. However, its extreme potency raises safety concerns, and no human clinical trials have been conducted.
