The NCI Drug Dictionary contains technical definitions and synonyms for drugs/agents used to treat patients with cancer or conditions related to cancer. Each drug entry includes links to check for clinical trials listed in NCI's List of Cancer Clinical Trials.

A small molecular-weight, malonic acid-based probe [(2-(5-fluoro-pentyl)-2-methyl-malonic acid or ML-10] labeled with the radioactive isotope fluorine F 18 with potential apoptosis radioimaging use. Upon administration, [F18]-ML-10 binds selectively to apoptotic cells due to apoptotic cell membrane features that differ from those of normal, healthy and necrotic cell membranes. Upon entering the apoptotic cell, this agent accumulates within the cytoplasm where it can be imaged using positron emission tomography (PET). Detection of apoptotic cells using this imaging technology may be useful in monitoring tumor responses to cytotoxic therapies. ML-10 appears to mimic the alkyl-malonic acid motif present in gamma -carboxyglutamic (Gla), an amino acid that plays a crucial role in the binding of clotting factors to negatively-charged phospholipids exposed on the surfaces of apoptotic cells. Check for active clinical trials using this agent. (NCI Thesaurus)
