  Small Molecule Ligands for Active Targeting of TrkC-Expressing Tumor Cells

  摘要：

  A small molecule motif was used in "active targeting" to deliver cytotoxic substances into tumor cells that express the TrkC receptor. Underlying this study was the hypothesis that internalization of targeted conjugates into cells would be facile if mediated by receptor binding and receptor ligand internalization. Initial experiments using 6-mercaptopurine gave encouraging data but demonstrated the importance of maintaining solubility and high cytotoxicity. Conjugates of the targeting agent with a cytotoxic rosamine (similar to a rhodamine) were more successful. Targeting of TrkC was observed, validated in a series of competition experiments featuring other TrkC ligands, and accumulation into lysosomes was observed, as expected for receptor-mediated internalization.
