[Decurarization using the cation-anion molecular interaction of a myorelaxant and its antagonist].
In experiments on the cat neuromuscular preparation the authors investigated the anticurare action of the new compound IEM-931 having sulphonate-anionic groups 20 A apart. The new compound administered in a dose of 184 mkM/kg prevents and removes the curare effect of rythetronium which is its structural analogue. Regarding tubocurarine the antagonism is displayed, however, only from the dose of 384 mkM/kg. This indicates that efficacy of the anticurare action of IEM-931 is directly related to complimentarity of the interacting molecule structure. The experiment with regional relaxation of the cat muscles shows that the anticurare action of IEM-931 is realized both in the blood and on the cholinoreceptor. Moreover, as a result of molecular interaction the inactive complex is formed.
