    Kuca K, Juna D, Musilek K. Structural requirements of acetylcholinesterase reactivators. Mini Rev Med Chem. 2006;6:269-77 pubmed
    ..It is shown that there are several structural fragments possibly involving in the structure of proposed AChE reactivators. Finally, an attempt of a future course of new AChE reactivators development is discussed. ..

    ..Thus, oxime K033 seems to be a relatively efficacious broad spectrum acetylcholinesterase reactivator and, therefore, could be useful if no information about the type of nerve agent used was available. ..
