Overview

Dihexa is classified as a neurotropic peptide peptide. Synaptogenesis, memory enhancement, cognitive repair, angiotensin IV activity.

Angiotensin IV analog developed at Washington State University. Binds hepatocyte growth factor (HGF) and potentiates its binding to the c-Met receptor, triggering downstream synaptogenesis cascades in hippocampal neurons. Reported to be 7 orders of magnitude more potent than BDNF for synaptic formation in vitro. Crosses blood-brain barrier and is orally bioavailable. Produces dose-dependent improvements in spatial memory in rodent models of cognitive impairment.

Also known as: N-hexanoic-Tyr-Ile-(6) aminohexanoic amide, PNB-0408

How Does Dihexa Work?

Angiotensin IV analog developed at Washington State University. Binds hepatocyte growth factor (HGF) and potentiates its binding to the c-Met receptor, triggering downstream synaptogenesis cascades in hippocampal neurons. Reported to be 7 orders of magnitude more potent than BDNF for synaptic formation in vitro. Crosses blood-brain barrier and is orally bioavailable. Produces dose-dependent improvements in spatial memory in rodent models of cognitive impairment.

At the molecular level, Dihexa operates through pathways characteristic of the Neurotropic Peptide class, interacting with target receptors and downstream signaling cascades to produce its observed effects.
