Abstract
Poziomek, Hackley and Steinberg (1958) and, independently, Hobbiger, O\u27Sullivan and Sadler (1958) have recently described a series of NN\u27-polymethylenebis(4-hydroxyiminomethyl-pyridinium) compounds, which are potent reactivators of cholinesterases inhibited by organophosphate antichobinesterases. The most effective compound in this series NN\u27-trimethylenebis( 4-hydroxyimino-methyl-pyridinium bromide) (TMB-4) was reported to be an effective agent in protecting animals from the lethal poisoning by methylphosphorofluoridate (SARIN), DFP and TEPP (Bay, Krop and Yates, 1958; Berry, Davies and Green, 1959; Hobbig er and Sadler, 1959). In this paper additional experiments are described, carried out to estimate the antagonism of TMB-4 toward some other organo-P-compounds. A number of specific nonphosphorus anticholinesterases are included as well.TMB-4 pokazao se uspješnim u zaštiti miševa, koji su otrovani Ietalnim dozama paraoksona, parationa, metasistoksa, neostigmina, eserina, a djelomično i R0-2-1250, dimefoksa i ditereksa. Njegovo djelovanje, međutim, ne pruža dovoljnu zaštitu miševa otrovanih OMPA-om i BW284C51
