title: [The effect of 1-adamantyl radicals on curare-like activity].
abstract: In the series of polymethylene bis-ammonium salts R(CH3)2N(CH2)NN(CH3)2R . 2I--(R=CH3 or Ad) a study was made of the significance of hydrophobic 1-adamantyle radicals (1--Ad) for curare-like activity. Administration of 1-ad radicals into the cation groups of depolarizing agents (n-9--11) altered their mechanism of action and diminished their activity. Attachmeni of 1-Ad radicals to the both quarternary nitrogen atoms of the antidepolarizing agents (n=5 and 6) sharply increased their curare-like activity. The data obtained pointed to the presence of hydrophobic zones in the cholinoreceptors of skeletal muscles.
