NCI Drug Dictionary

  

Fluorine F 18 ISO-1 
A radioconjugate consisting of the benzamide ligand ISO-1 labeled with the radioisotope fluorine F18 with positron-emitting radioisotope activity. Upon administration, fluorine [F18]ISO-1 binds to sigma-2 receptors, located on tumor cells, allowing visualization of sigma-2 receptor-expressing tumor cells with positron emission tomography (PET). Sigma-2 receptors, expressed in a variety of normal healthy tissues such as liver, kidneys, endocrine glands, and in the central nervous system, may be overexpressed in tumor cells. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
