    • Detoxification of humans who have been exposed to phosphylating agents, and decontamination of a locus containing phosphylating agents (e.g. organophosphorus insecticides or organophosphorus nerve gases), are effected by administration to the humans or applying to the locus, respectively, at least one recombinant cholinesterase mutant so as to form phosphylated cholinesterase mutant, in presence of intrinsic or extrinsic reactivator activity effective to reactivate the mutant by breaking the phosphyl/cholinesterase mutant covalent bond, the phosphylated mutant being more readily reconverted to nonphosphylated mutant, than the corresponding phosphylated non-mutated cholinesterase is reconverted to non-phosphylated non-mutated cholinesterase. Mutation sites in the amino acid sequence of HuAChE, or in equivalent positions in other cholinesterases, are preferably selected from at least one of (a) Ser2 3, Glu334, His447; (b) Gly122, Tyr133, Glu2 2, Ser229, Gly448, Glu45 ; (c) Leu76, Tyr77, Trp86, Tyr117, Tyr119, Gly12 , Gly121, Trp236, Phe295, Phe297, Tyr337, Phe338, Trp439, Tyr449; and/or (d) Tyr72, Asp74, Tyr124, Glu285, Trp286, Tyr341. The invention includes use of the (non-phosphylated) mutants for the manufacture of medicaments for detoxification, pharmaceutical formulations for detoxification, compositions for decontamination, and phosphylated and non-phosphylated recombinant cholinesterase mutants, per se .
    • 已经暴露于磷酸化剂的人的解毒以及含有磷酸化剂(例如有机磷杀虫剂或有机磷神经气体)的场所的去污是通过给予人类或分别施用至该基因座的至少一种重组胆碱酯酶突变体 以便形成磷酸化胆碱酯酶突变体,在通过断裂磷酸/胆碱酯酶突变共价键有效重新激活突变体的本征或外源性激活剂活性存在下,磷酸化突变体比相应的磷酸化非突变胆碱酯酶更容易再转化为非磷酸化突变体 被转化为非磷酸化的非突变型胆碱酯酶。 HuAChE的氨基酸序列中的突变位点或其他胆碱酯酶中的等位基因的优选选自以下中的至少一种:(a)Ser2 @ 3,Glu334,His447; (b)Gly122,Tyr133,Glu2 @ @ 2,Ser229,Gly448,Glu45; (c)Leu76,Tyr77,Trp86,Tyr117,Tyr119,Gly121,Gly121,Trp236,Phe295,Phe297,Tyr337,Phe338,Trp439,Tyr449; 和/或(d)Tyr72,Asp74,Tyr124,Glu285,Trp286,Tyr341。 本发明包括使用(非磷酸化)突变体用于制造用于解毒的药物,用于解毒的药物制剂,用于去污的组合物,以及磷酸化和非磷酸化的重组胆碱酯酶突变体本身。

    • In a method for detecting particular classes of explosives, a suspect sample is subjected serially to reagents (1), (2), (3) and (4) in the liquid phase, the reagents after the first being applied only if no color reaction has been obtained in the preceding test, while reagents (2) and (3) only are applied in presence of the preceding reagent(s). (1) is an alkaline solution of a diazotizable aminoaromatic azo-dye precursor (for nitroaromatic explosives). (2) is a strongly acidic reagent containing a nitrate to nitrite ion reducing agent and a diazo-coupler (for organic nitrates and nitramines). (3) is zinc powder suspended in a liquid comprising at least one water-miscible solvent (for inorganic nitrates). (4) is an aniline salt in a homogeneous strongly acidic solution including a water-miscible organic solvent (for chlorates and bromates). The invention includes also a test kit, as well as reagents (3) and (4), for use in the method.
