Misonidazole (MISO), a hypoxic cell radiosensitizer, forms covalently-linked adducts to cellular molecules as a result of bioreductive metabolism, a process which is strongly dependent upon oxygen concentration. MISO binding to liver tissue taken from air-breathing mice was three to five times greater than binding to other normal tissues. The relative(More)
Mature, confluent monolayer cultures of IEC-6 rat intestinal epithelial cells in conventional growth media express both Na(+)-linked, concentrative nucleoside transport (NT) activity and equilibrative, inhibitor-sensitive NT activity, but do not show morphologic differentiation. Na(+)-dependent fluxes of Ado and formycin B were minor in early subconfluent(More)
The binding rate of 14C-Misonidazole was determined for freshly isolated mouse hepatocytes, mouse hepatoma cells, EMT-6 tumor cells, and V79 Chinese hamster lung fibroblasts. At 10 microM drug concentration, the four different cell lines bound 14C-Misonidazole at rates of 12.4, 29.9, 51.6, and 13.5 pmoles/10(6) cells/hr, respectively. This relative order of(More)
