Overview

Potent cognitive enhancer, angiotensin IV analog. Activates the HGF/c-Met pathway, promoting synaptogenesis and neurotrophism. Considered up to 10 million times more potent than BDNF in forming new synaptic connections in preclinical studies.

Extended notation: N-Hexanoyl-Tyr-Ile-(6)-aminohexanoic amide

Peptidomimetic — modified angiotensin IV derivative with hexanoyl and aminohexanoic chains

Half-life

~12 hours

Administration Route

Subcutaneous or oral

Category

Cognitive & Neuroprotective

Mechanism of Action

  • Activation of the HGF/c-Met pathway (hepatocyte growth factor)
  • Promotion of synaptogenesis and new neural connection formation
  • Potent neurotrophic effect
  • Prevention of HGF degradation by the heparanase enzyme
  • Improvement of synaptic plasticity and spatial memory
