Novel naphthalimides with two heterocyclic side chains of 2-nitroimidazole for bioreductive binding were designed, synthesized, and used as fluorescent markers for hypoxic cells. Their evaluation for imaging tumor hypoxia was carried Out in V79 cells, CHO cells, and 95D cells in vitro by using fluorescence scan ascent. A(2) and A(4) showed a very large differential fluorescence between hypoxic and oxic cells (V79 cells) in vitro and are promising candidate markers for hypoxic cells. (c) 2005 Elsevier Ltd.
