Adipotide: The Experimental "Fat Assassin"
Most weight loss drugs suppress appetite. Adipotide is different: it physically destroys the blood vessels feeding your fat cells.

Key Research Insights
- Adipotide(Prohibitin - TP01) is a peptidomimetic designed to target the blood supply of white adipose tissue.
- Unlike traditional weight loss agents that affect metabolism or appetite, Adipotide works via ** angiogenesis inhibition **.
- It selectively induces apoptosis(programmed cell death) in the vascular endothelial cells feeding fat tissue.
- Research in primate models demonstrated rapid, significant weight loss and reduction in BMI.
Mechanism of Action: Vascular Targeting
Targeting Prohibitin
Adipotide binds specifically to prohibitin, a protein receptor found on the surface of endothelial cells within the vasculature of white fat.This receptor is largely absent in the blood vessels of other tissues, providing a target for selective therapy.
Induced Apoptosis
Upon binding, the peptide is internalized and disrupts mitochondrial function within the endothelial cells.This triggers the caspase cascade, leading to apoptosis of the blood vessel cells.Without a blood supply, the downstream fat cells die(ischemic necrosis) and are resorbed by the body[1].
Clinical Research Findings
Primate Studies
In a landmark study involving obese rhesus monkeys, Adipotide administration led to an average weight loss of 11 % over just 4 weeks.Reductions were specifically noted in abdominal circumference and BMI.Metabolic markers, including insulin resistance, also improved significantly[2].
Renal Implications
The primary side effect identified in research is nephrotoxicity.The mechanism involves renal proximal tubule lesions, which appear to be dose - dependent and reversible.This has limited its human clinical development and emphasizes the need for careful monitoring in research settings.
