The ability of chemical radiation sensitizers such as misonidazole (MISO) to potentiate certain chemotherapeutic agents has been recognized for several years. Anti-tumour agents whose activities are most effectively enhanced both in vitro and in vivo by sensitizers include cyclophosphamide, melphalan and the nitrosoureas (for review see Millar, 1982; McNally, 1982; Siemann, 1982, 1984). In vitro experiments of chemopotentiation have concentrated primarily on exposing cells to the sensitizer in the absence of oxygen (usually for a period of 2-4h) prior to treatment with the chemotherapeutic agent in air. These investigations, usually referred to as" MISO pre-incubation experiments" have been performed inattempts to develop mechanisms of action for the phenomenon of chemopotentiation (Brown, 1982). Several anti-tumour drugs have been investigated extensively in this manner; particularly the alkylating agent melphalan (Stratford et al., 1980; Roizin-Towle & Hall, 1981; Taylor et al., 1982). Invitro combinations of nitrosoureas and MISO, especially those evaluating the hypoxic cell pre-incubation effects, have been far more limited (Twentyman, 1980, 1982) despite the large enhancement ratios which can be obtained when MISO is added to in vivo therapies incorporating some of the compounds in this anti-tumour agent class (McNally, 1982; Siemann, 1982, 1984). The nitrosoureas represent an important class of chemotherapeutic agents in the treatment of human malignancies, particularly brain tumours (Levin & Wilson, 1976). Consequently, in view of the substantial potentiation and increased therapeutic benefits observed when certain nitrosoureas and MISO are combined, experiments were initiated to evaluate the possibility of utilizing such combined
