Angiotensin IV–related peptide analogue researched for cognitive function and neuroplasticity.
Dihexa is a synthetic peptide analogue related to angiotensin IV. It functions by enhancing neuroplasticity through the activation of hepatocyte growth factor (HGF) and its receptor, c-Met, which are crucial for neural repair and cognitive enhancement. Early work on Dihexa focused on its potential for improving cognitive function and memory in neurodegenerative conditions. Researchers have also explored its effects on synaptic transmission and neuron connectivity. Today, it is primarily studied for its effects on:
- Cognitive enhancement
- Neuroplasticity
- Memory improvement
- Neurodegenerative disease research
- Synaptic transmission studies
