comparable to that of cyclophosphamide. However, there was no evidence that the yield of phosphoramide mustard produced by the trans analogues were significantly greater than that from cyclophosphamide following microsomal 4-hydroxylation. Hence, the halogen substituents did not accelerate beta-elimination of acrolein from the acyclic aldehydo tautomers. As expected, the poorly metabolized cis-5-fluoride (9)

The invention relates generally to compounds and methods for imaging and/or selective ablation of nitroreductase-expressing cells and/or biological agents. More particularly, although not exclusively, the invention provides compounds that are selectively metabolised by bacterial nitroreductases and are substantially insensitive to metabolism under oxic or hypoxic conditions by human nitroreductase enzymes.
The present invention relates to novel radioactively labeled bioreducible tracers of Formula I useful for detecting hypoxic tumors or ischemic tissue in vivo. In one embodiment, the tracers consist of a 2-nitroimidazole moiety, a triazole, metabolically stable linker with pharmacokinetics enhancing substituents, and a radioisotope. The preferred in vivo imaging modality is positron emission tomography.
