• Synthesis and Evaluation of Novel Polyaminocarboxylate-Based Antitumor Agents

  Iron depletion, using iron chelators targeting transferrin receptor (TfR) and ribonucleotide reductase (RR), is proven to be effective in the treatment of cancer. We synthesized and evaluated novel polyarninocarboxylate-based chelators NETA, NE3TA, and NE3TA-Bn and their bifunctional versions C-NETA, C-NE3TA, and N-NE3TA for use in iron depletion tumor therapy. The cytotoxic activities of the novel polyaminocarboxylates were evaluated in the HeLa and HT29 colon cancer cell lines and compared to the clinically available iron depletion agent DFO and the frequently explored polyaminocarboxylate DTPA. All new chelators except C-NETA displayed enhanced cytotoxicities in both HeLa and HT29 cancer cells compared to DFO and DTPA. Incorporation of the nitro functional unit for conjugation to a targeting moiety into the two potent non-functionalized chelators NE3TA and NE3TA-Bn (C-NE3TA and N-NE3TA) was well-tolerated and resulted in a minimal decrease in cytotoxicity. Cellular uptake of C-NE3TA, examined using a confocal microscope, indicates that the chelator is taken up into HT29 cancer cells.
• Novel 64Cu-radiolabeled bile acid conjugates for targeted PET imaging

  A promising bifunctional chelate (N-NE3TA) was conjugated to bile acids, cholic acid (CA), deoxycholic acid (DCA), and chenodeoxycholic acid (CDCA) as tumor targeting vectors. Bile acid conjugates of N-NE3TA (CA-N-NE3TA, DCA-N-NE3TA, and CDCA-N-NE3TA) were comparatively evaluated for complexation with Cu-64, an imaging probe for positron emission tomography (PET). N-NE3TA-bile acid conjugates were evaluated for radiolabeling kinetics with Cu-64, and the corresponding Cu-64-radiolabeled conjugates were screened for complex stability in human serum and EDTA solution. The NE3TA-bile acid conjugates instantly bound to Cu-64 with excellent radiolabeling efficiency at room temperature. All NE3TA-bile acid conjugates radiolabeled with Cu-64 remained inert in human serum for 2 days without releasing a considerable amount of the radioactivity. The Cu-64-radiolabeled complexes were further challenged by EDTA in a 100-fold molar excess. Bile acid-N-NE3TA conjugates radiolabeled with Cu-64 were quite stable with a minimal transfer of Cu-64 to EDTA at 4 h time point. The in vitro data indicate that the bile acid-N-NE3TA conjugates deserve further biological evaluation for Cu-64-based targeted PET imaging applications. (C) 2015 Elsevier Ltd. All rights reserved.
