Dihexa

Angiotensin IV Analogue

also known as N-hexanoic-Tyr-Ile-(6) aminohexanoic amide

Synthetic angiotensin IV analogue that activates the hepatocyte growth factor (HGF)/c-Met receptor system, inducing dendritic arborization and synaptogenesis in rodent models. Animal studies demonstrate cognitive enhancement and synapse formation in mouse Alzheimer's models. No human clinical data available. Pre-clinical stage only.

§ I

At a glance

Development stage
Pre-clinical
Evidence basis
Rodent only
Target system
HGF/c-Met
Route

Not established — animal studies only

§ II

Mechanism

Edit ↗

Primary target — c-Met receptor (HGF receptor tyrosine kinase).

Pathway — HGF/c-Met receptor activation → downstream signaling cascade → synaptogenesis and dendritic arborization.

Downstream effect — Induction of dendritic arborization, synapse formation, neurogenesis, and neuroprotection in rodent models.

Origin — Small-molecule angiotensin IV analogue designed to activate HGF/c-Met system [wright-2015].

Adverse events

Severities follow the FDA / CTCAE convention.

Edit ↗
Human safety datasevere
None available — no human clinical trials
Theoretical c-Met riskssevere
c-Met receptor activation has been implicated in tumorigenesis; unknown cancer risk profile
Pre-clinical tolerability
Not systematically reported in available studies
Absolute contraindications
  • Not approved for human use — research compound only
Relative contraindications
  • Theoretical contraindication: active or history of malignancy (c-Met pathway involvement in cancer)
§ VI

Administration

Edit ↗
  1. 01
    Human administration

    No established protocol. Dihexa has not been tested in human subjects. Animal studies used various routes (typically subcutaneous or intraperitoneal in rodents) not translatable to clinical use.

  2. 02
    Legal status

    Pre-clinical research compound. Not approved by FDA or any regulatory authority for human use.
