  Automated Modular Synthesis of Aptamer–Drug Conjugates for Targeted Drug Delivery

  摘要：

  Aptamer-drug conjugates (ApDCs) are promising targeted drug delivery systems for reducing toxicity while increasing the efficacy of chemotherapy. However, current ApDC technologies suffer from problems caused by the complicated preparation and low controllability of drug aptamer conjugation. To solve such problems, we have designed and synthesized a therapeutic module for solid phase synthesis, which is a phosphoramdite containing an anticancer drug moiety and a photocleavable linker. Using this module, we have realized automated and modular synthesis of ApDCs, and multiple drugs were efficiently incorporated into ApDCs at predesigned positions. The ApDCs not only recognize target cancer cells specifically, but also release drugs in a photocontrollable manner. We demonstrated the potential of automated and modular ApDC technology for applications in targeted cancer therapy.

  report the first examples of strongly hydrophilic copper(II) complexes of 5,10,15,20-tetraaryl-5,15-diazaporphyrins (TADAPs) substituted with carboxy or (2,3-dihydroxypropyl)carbamoyl groups. Metal-templated cyclization reactions of a common dipyrrin precursor with nickel(II) or copper(II) acetate afforded the corresponding metal(II) complexes of 5,10,15,20-tetrakis(4-alkoxycarbonylphenyl)-5,15-diazaporphyrin
