Dihexa

Dihexa

Also known as: PNB-0408, Hepatocyte Growth Factor Mimetic

Overview

Key Facts

Primary Goal: Research and therapeutic applications of Dihexa

Binds hepatocyte growth factor (HGF) receptor c-Met to augment signaling. Potently stimulates dendritic spine formation and synaptogenesis.

Dosing Information

Half-Life

~6 hours (estimated)

Typical Dose

10–40 mg

Frequency

1x daily (oral or intranasal)

Cycle Length

2-4 weeks, with breaks

Administration Routes:
subcutaneousoral

Benefits

  • Profoundly augments synaptic connectivity and spinogenesis
  • Neuroprotective against neurotoxin-induced damage
  • Improves memory and cognitive function in animal models
  • Promotes hepatocyte growth factor (HGF) signaling for brain repair
  • Potential application in traumatic brain injury recovery

Side Effects

Headachemild
Mild anxiety or overstimulationmild
Insomnia if taken late in the daymild
Blood pressure changes (theoretical, angiotensin-related)mild
Long-term safety profile unknownmild

Mechanism of Action

1

Binds hepatocyte growth factor (HGF) receptor c-Met to augment signaling

2

Potently stimulates dendritic spine formation and synaptogenesis

3

Activates the HGF/c-Met/PI3K pathway for neuronal survival

4

Resistant to enzymatic degradation by peptidases

5

Crosses the blood-brain barrier via oral administration

Contraindications

Do not use this peptide if any of the following apply:

  • Active cancer (HGF/c-Met pathway involved in tumour growth)
  • Pregnancy or breastfeeding
  • Uncontrolled hypertension
