摘要

氧胺吡啶与磷酸烷基乐果及其衍生物的反应。对胆碱酯酶的影响乐果是一种二甲氧基二硫代烷基磷酸盐,对乙酰胆碱酯酶(EC 3.1.1.7)和胆碱酯酶(EC 3.1.1.8)无抑制作用。异构化产物(二硫醇衍生物)和氧化产物(O类似物)可能导致观察到的抑制作用。这些衍生物是相对较弱的胆碱酯酶抑制剂。试图重新激活被这些乐果衍生物抑制的胆碱酯酶。如果磷酸烷基和肟的浓度足够高,所使用的所有吡啶肟对酶都有较强的抑制作用。讨论了一种可能解释这些效应的反应方案。

Reaktionen von pyridinium oximen mit dem alkylphosphat dimethoat und seinen derivaten wirkung auf cholinesterasen

Reactions of pyridinium oximes with the alkyl phosphate dimethoate and its derivatives. Effects upon cholinesterases

  • 1.

    1. Dimethoate (Rogor), a dimethoxydithioalkyl phosphate, does not inhibit the enzymes acetylcholinesterase (EC 3.1.1.7) and cholinesterase (EC 3.1.1.8). An isomerization product (the dithiol derivative) and an oxidation product (the O analogue) may be responsible for observed inhibitory effects. These derivatives are relatively weak inhibitors of cholinesterases.

  • 2.

    2. An attempt was made to reactivate the cholinesterases inhibited by these dimethoate derivatives. All the pyridinium oximes employed produced a stronger inhibition of the enzymes, if the concentrations of alkyl phosphate and oxime were high enough.

  • 3.

    3. A reaction scheme with a possible explanation for these effects is discussed.
