Adipotide
Also known as: FTPP, prohibitin-targeting peptide, proapoptotic fat peptide
Adipotide (FTPP) is a chimeric proapoptotic peptide that selectively targets and destroys blood vessels feeding white adipose tissue. It binds prohibitin on the vasculature of fat tissue, delivering a proapoptotic sequence that induces cell death in fat-specific blood vessels, causing targeted fat tissue regression.

Key Benefits
- Targeted reduction of white adipose tissue
- Promotes fat vasculature apoptosis without systemic toxicity
- Demonstrated significant fat loss in primate studies
- Potential for visceral and subcutaneous fat reduction
- Novel non-hormonal mechanism distinct from GLP-1 agonists
- Explored for obesity and metabolic syndrome
Mechanism of Action
Adipotide consists of a targeting sequence (CKGGRAKDC) that binds prohibitin on white adipose tissue vasculature, linked to a proapoptotic sequence (KLAKLAKKLAKLAK, also known as D(KLAKLAK)2). The targeting sequence homes to fat vasculature, and the proapoptotic sequence disrupts mitochondrial membranes in those endothelial cells, triggering programmed cell death. This selectively cuts off blood supply to adipose tissue, causing fat cell death without affecting other tissues.
