  Nitrobenzocyclophosphamides as potential prodrugs for bioreductive activation: synthesis, stability, enzymatic reduction, and antiproliferative activity in cell culture

  摘要：

  In efforts to obtain potential anticancer prodrugs for gene-directed enzyme prodrug therapy using Eschericia coli nitroreductase, a series of four benzocyclophosphamide analogues were designed and synthesized incorporating a strategically placed nitro group in a position para to the benzylic carbon for reductive activation. All four analogues were found to be stable in phosphate buffer at pH 7.4 and 37 degreesC and were good substrates of E. coli nitroreductase with half lives between 7 and 24 min at pH 7.0 and 37 degreesC. However, only two analogues 6a and 6c, both with a benzylic oxygen in the phosphorinane ring para to the nitro group, showed a modest 33-36-fold enhanced cytotoxicity in E. coli nitroreductase-expressing cells. These results suggest that good substrate activity and the para benzylic oxygen are required for activation by E. coli nitroreductase. Compounds 6a and 6c represent a new structure type for reductive activation and a lead for further modification in the development of better analogues with improved selective toxicity to be used in gene-directed enzyme prodrug therapy.
