Description
Dihexa Capsules | AT4/IRAP Inhibitor — Cognitive Research
Dihexa (N-hexanoic-Tyr-Ile-(6) aminohexanoic amide) is an angiotensin IV analogue reported to be approximately 10 million times more potent than BDNF in synaptogenesis models. As an AT4/IRAP inhibitor, it potentiates HGF/MET signaling — a pathway involved in synapse formation and cognitive processing. This capsule format (10mg per capsule, 30 capsules) supports oral research protocols studying neuroplasticity and cognitive function.
Mechanism of Action
- AT4/IRAP inhibition — blocks insulin-regulated aminopeptidase, prolonging action of endogenous neuropeptides at synaptic sites
- HGF/MET potentiation — amplifies hepatocyte growth factor signaling through MET receptor, promoting dendritic spine formation
- Synaptogenesis — preclinical models show new synapse formation in hippocampal and cortical regions
- BDNF-independent pathway — acts through a mechanistically distinct route from classical neurotrophins
Research Areas
Dihexa is studied in models of cognitive impairment, neurodegeneration, hippocampal plasticity, and HGF/MET-related neuropathology. Research comparators include Semax (BDNF upregulation) and Selank (anxiolytic neuropeptide) for comprehensive cognitive research panels.
