Dihexa, also known as N-hexanoic-Tyr-Ile-(6) aminohexanoic amide, is an oligopeptide derived from angiotensin IV. It binds with high affinity to hepatocyte growth factor (HGF) and enhances its activity at the c-Met receptor.
Dihexa has shown significant potential in improving cognitive function in animal models of Alzheimer’s disease-like mental impairment, demonstrating neurotrophic activity seven orders of magnitude more potent than brain-derived neurotrophic factor.
Developed by Joseph Harding and his team at Washington State University, dihexa has been further advanced by M3 Biotechnology. A pro-drug of dihexa, fosgonimeton, is currently in clinical trials for neurodegenerative diseases like Alzheimer’s and Parkinson’s. While short-term safety studies indicate no apparent toxicity, long-term safety, including potential tumorigenic effects, remains unstudied.
