The article deals with the hydrophobic character (distribution coefficient in the systems hexane - water and chloroform - water) and certain peculiarities of distributing three cation-containing phosphoroganic inhibitors of cholinesterase and their uncharged analogues in the organisms. The distribution coefficients in the charged and uncharged compounds in the system hexane - water differ inconsiderably, whereas in the system chloroform-water by the thousands and millions times. In rabbits with intravenous administration the content of all inhibitors in blood decreases rapidly, the uncharged compounds accumulate selectively in the lungs and the charged ones are distributed evenly in the tissues.
本文探讨了含三个阳离子的有机磷胆碱酯酶抑制剂及其不带电荷类似物的疏水特性(在正己烷-水和氯仿-水体系中的分配系数)以及在生物体内分布的某些特点。在正己烷-水体系中,带电荷和不带电荷化合物的分配系数差异不大,而在氯仿-水体系中则相差数千倍甚至数百万倍。静脉给药的兔子体内,所有抑制剂在血液中的含量迅速下降,不带电荷的化合物选择性地在肺部蓄积,而带电荷的化合物则均匀分布于各组织中。
