The prophylactic efficacy of various simulators against intoxication with the organophosphate soman: structure-activity studies

The effects were investigated of structural variations of the soman simulator pinacolyl dimethylphosphinate on its efficacy to prevent secondary failure of oxime-induced recovery of neuromuscular transmission and death after soman intoxication. The simulators were administered prophylactically to atropinized, HI-6 treated rats, dosed with 6 or 8 X LD50 soman. In these new simulators the pinacolyl moiety was varied, the phosphonyl oxygen atom was...
