  Design, Synthesis, and Biological Evaluation of Cyclic and Acyclic Nitrobenzylphosphoramide Mustards for E. coli Nitroreductase Activation

  摘要：

  In efforts to obtain anticancer prodrugs for antibody-directed or gene-directed enzyme prodrug therapy using E. coli nitroreductase, a series of nitrobenzylphosphoramide mustards were designed and synthesized incorporating a strategically placed nitro group in a position para to the benzylic carbon for reductive activation. All analogues were good substrates of E. coli nitroreductase with half-lives between 2.9 and 11.9 min at pH 7.0 and 37 degrees C. Isomers of the 4-nitrophenylcyclophosphamide analogues 3 and 5 with a benzylic oxygen para to the nitro group showed potent selective cytotoxicity in nitroreductase (NTR) expressing cells, while analogues 4 and 6 with a benzylic nitrogen para to the nitro group showed little selective cytotoxicity despite their good substrate activity. These results suggest that good substrate activity and the benzylic oxygen are both required for reductive activation of 4-nitrophenylcyclophosphamide analogues by E. coli nitroreductase. Isomers of analogue 3 showed 23000-29000 x selective cytotoxicity toward NTR-expressing V79 cells with an IC50 as low as 27 nM. They are about as active as and 3-4x more selective than 5-aziridinyl-2,4-dinitrobenzamide (CB1954). The acyclic 4-nitrobenzylphosphoramide mustard ((+/-)-7) was found to be the most active and most selective compound for activation by NTR with 170000x selective cytotoxicity toward NTR-expressing V79 cells and an IC50 of 0.4 nM. Compound (+/-)-7 also exhibited good bystander effect compared to 5-aziridinyl-2,4-dinitrobenzamide. The low IC50, high selectivity, and good bystander effects of nitrobenzylphosphoramide mustards in NTR-expressing cells suggest that they could be used in combination with E. coli nitroreductase in enzyme prodrug therapy.

• A Simple One-Pot Procedure for the Direct Conversion of Alcohols to Azides via Phosphate Activation
  作者：Chengzhi Yu、Bin Liu、Longqin Hu

  日期：2000.6.1

  A one-pot procedure was developed to prepare efficiently alkyl azides from alkanols using bis(2,4-dichlorophenyl) phosphate activation. 4-(Dimethylamino)pyridine was used as a base, and phosphorylpyridinium azide is believed to be the activating agent under this condition.

  开发了一锅法以使用双（2,4-二氯苯基）磷酸酯活化从烷醇有效制备烷基叠氮化物。使用4-（二甲基氨基）吡啶作为碱，在这种条件下，叠氮化磷酸吡啶被认为是活化剂。
