HOPO 14-1 is an investigational drug product for removing radioactive contaminants from the body. It is an oral capsule designed to act as a defence against radioactive threats such as nuclear power plant accidents or dirty bomb attacks.[ 1] [ 2] The active ingredient is the hydroxypyridinone ligand 3,4,3-LI(1,2-HOPO), which is a powerful chelating agent.[ 1] [ 3] HOPO 14-1 works by selectively binding to heavy metals in the body and forming a complex that the body can naturally excrete.[ 4] The drug is also being studied as a treatment for other forms of heavy metal toxicity , including lead poisoning and exposure to gadolinium from MRI contrast agents .[ 5] [ 6] [ 7] [ 8] HOPO 14-1 was developed at Lawrence Berkeley National Laboratory by actinide chemist Rebecca Abergel . Abergel and former postdoc Julian Avery Rees co-founded HOPO Therapeutics , a company commercializing HOPO 14-1 and other treatments for heavy metal poisoning.
