AHK-Cu (Ala-His-Lys copper complex), also known as Copper Tripeptide-3, is a synthetic copper-binding research peptide composed of alanine, histidine, and lysine coordinated to a divalent copper ion (Cu2+). Available in 100mg lyophilized vials, ahk cu 100mg is studied in preclinical research for hair follicle biology, collagen synthesis, and tissue repair mechanisms. NuScience Peptides supplies AHK-Cu 100mg for qualified research use only.

AHK-containing peptides (tripeptides such as Ala–His–Lys, and related sequences like Asp–Ala–His–Lys or Gly–His–Lys) have been used in multiple rat models to probe tissue protection, wound healing, metabolic effects, and neuroprotection. In experimental rodents these short peptides are attractive because they are small (good tissue diffusion), often bind metal ions (modifying redox or growth-factor signaling), and can modulate inflammation, apoptosis, and repair pathways. For example, the tetrapeptide DAHK (L-Asp-Ala-His-Lys), a fragment of human serum albumin, produced robust neuroprotection in a rat permanent middle-cerebral-artery-occlusion model: a single i.v. dose (16 mg/kg, 30 minutes after occlusion) reduced infarct area and markedly improved neurological scores compared with saline controls.

AHK-Cu Research Applications

Related AHK-containing constructs have been tested for metabolic and antioxidant effects: a deuterohemin–AlaHisLys mimic (DhHP-3) lowered blood glucose, reduced oxidative stress markers, increased antioxidant enzyme activity, and protected pancreatic β-cells in a rat model of non-insulin-dependent diabetes, suggesting ROS scavenging and PI3K/Akt pathway activation as mechanisms. (PubMed)

The broader family of histidine-containing tripeptides (notably GHK and its copper complex) has extensive rat literature showing wound-healing, anti-inflammatory, and neuroprotective effects. Gly-His-Lys (GHK) improved neurological recovery, reduced brain edema, and decreased neuronal apoptosis in rat intracerebral-hemorrhage models; mechanistic data point to modulation of microRNAs, VEGF signaling, Akt/PI3K pathways, and lowered inflammatory mediators. (PubMed)

Across these studies, routes of administration vary (intravenous, intraperitoneal, topical, or intracutaneous), doses range widely depending on peptide and model, and beneficial outcomes are commonly linked to reduced oxidative stress, modulation of growth-factor/signaling cascades, and improved histological repair. While promising in rodents, translation requires careful pharmacokinetic and toxicity studies.
