    Dihexa

    Phase 1 TrialsInvestigational compound, not FDA-approved for any medical use. Preclinical research suggests potential applications for neurodegenerative conditions, particularly Alzheimer disease.

    Dihexa

    Description

    A potent nootropic peptide derived from BDNF that enhances memory, learning, and cognitive function. Crosses the blood-brain barrier effectively.

    Dose:5-10 mg
    Frequency:Daily
    Administration Method: SQ, Oral
    CategoryNootropic
    Half-Life12 days following i.v. administration and 8.8 days following i.p. administration in rats; unknown for humans

    Overview

    Dihexa (N-hexanoic-tyrosine-isoleucine-(6) aminohexanoic amide) is a synthetic neuropeptide derived from angiotensin IV. It was developed by researchers at Washington State University as a potential treatment for neurodegenerative conditions and chemically modified to enhance potency and blood-brain barrier penetration.

    Mechanism of Action

    Dihexa binds with high affinity to hepatocyte growth factor (HGF) and promotes c-Met signaling and HGF-dependent cellular activity. Activation of c-Met can stimulate neurogenesis and protect against tissue insults in many cell types including neurons. These activities are linked to improved cognitive function and increased dendritic arborization, spinogenesis, and synaptogenesis.

    Benefits

    • •Cognitive enhancement
    • •Memory improvement
    • •Neuroplasticity
    • •Learning enhancement
    • •Neuroprotection
    • •Dementia research

    Dosing Notes

    Not established. In rats, dihexa has been tested orally at 2 mg/kg, i.c.v. at up to 1 nmol, i.v. at up to 10 mg/kg, and i.p. at up to 20 mg/kg.

    Reported Side Effects

    • •Headache
    • •Injection site reactions
    • •Limited long-term human data

    Safety Notes

    No long-term safety studies in animals or humans exist. There are theoretical concerns of c-Met activation leading to tumorigenesis and cancer progression.
