Based on in vitro and in vivo rat experiments, the newly developed acetylcholinesterase (AChE) reactivator, K203, appears to be much more effective in the treatment of tabun poisonings than currently fielded oximes.

A notable achievement by the U.S. Army as of early 2012 is that 90 percent of the legacy chemical weapons and other chemical warfare materiel (CWM) from the Second World War and cold war eras and then stockpiled by the United States have been safely destroyed. 1 Whatever cumulative risk had been posed by the existence of this CWM to communi-ties surrounding the six military sites where it was guarded and safely maintained since the mid-twentieth century is now zero.

Human serum paraoxonase 1 (HuPON1; EC 3.1.8.1) is a calcium-depend-ent six-foldb-propeller enzyme that has been shown to hydrolyze an array of substrates, including organophosphorus (OP) chemical warfare nerve agents. Although recent efforts utilizing site-directed mutagenesis have demonstrated specific residues (such as Phe222 and His115) to be import-

Introduction: Chemical weapons (chemical warfare agents), such as sarin and soman, were developed to kill or injure humans by their toxic actions. They are called “nuclear weapon of the poor”, because the weapons are relatively stable during storage, cheap for production and relatively easily synthesized with basic knowledge on organic chemistry. Main advanced countries are making efforts to reduce chemical weapons existing in the world on the basis of the Chemical Weapons Convention (CWC), after the Iran-Iraq War and the Gulf War.

Introduction: The chemical warfare agents well known count only about 30 kinds of compounds, such as sarin, soman, tabun, VX, mustard gas, lewisite and others. When unknown toxic substances should be analyzed upon the occurrence of chemical terrorism, much more kinds of poisons and related compounds become the objects of analysis. In the Chemical Weapons Convention (CWC)a, 120 thousand compoundsb, including typical chemical warfare agents, their related compounds, precursors and decomposition products, are being listed to be controlled.
