摘要

The effect of combining a radiation-protective phosphorothioate with another agent was investigated in an attempt to increase radioprotection and reduce toxicity. The calcium channel blocker nimodipine (NIMO) was administered alone (1 or 10 mg kg-1) or in combination with 200 mg kg-1 of the phosphorothioate radioprotector WR-151327 (WR) (S-3-(3-methylaminopropylamino)propylphosphorothioic acid). Radioprotection as measured (30-day survival) of mice treated i.p. 30 min before (60)Co irradiation at a dose rate of 1 Gy min-1 was evaluated in CD2F1 male mice. The effects of nimodipine and WR-151327 on locomotor activity were investigated also in a separate group of non-irradiated mice. The LD(50/30) for the Emulphor vehicle control group was 8.56. For nimodipine alone (1 or 10 mg kg-1) the LD(50/30)was 8.39 and 10.21 Gy, respectively, yielding dose modification factors (DMFs) of 0.98 and 1.19, respectively. When WR-151327 was given alone, the
