iodine I 131 NM404
A phospholipid ether analog labeled with iodine I 131, with potential radiotherapeutic and radioimaging potential upon positron emission tomography (PET). Upon administration, iodine I 131 NM404 selectively accumulates in and is retained within tumor cells for a prolonged period of time due to the decreased activity of a phospholipase D (PLD), most likely isoform 1 of PLD, in tumor cells compared to normal cells. As tumor cells are unable to metabolize and eliminate MN404, tumor cells can be visualized upon PET imaging. In addition, iodine I 131 NM404 selectively delivers a cytotoxic dose of iodine I 131 to the tumor cells. PLD is an enzyme found in the cell membrane of normal cells that degrades phospholipids. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
