Chemical warfare nerve agents (NAs) are one of the important groups of organophosphorous (OP) compounds that have been used as tactical weapons and for terrorism during recent decades . . .
The NAs are traditionally classified into two classes of G and V agents, but also GV compounds (GV:2-dimethylaminoethyl-(dimethylamido)-fluorophosphate) which contained structures of both G and V agent . . .
Recently a new type of NAs has been claimed to develop named "Novichoks" (means “newcomer” in Russia). This has been attracting increasing attention in recent years, particularly among non-governmental organizations (NGOs). It has been claimed that the toxicity of certain “Novichok” agents may exceed that of VX. The action mechanism is also dissimilar to the other NAs and thus conventional antidotes may be ineffective. Though, to date, there is nothing in details on such chemical has ever been declared in the literature [7,8]. NAs are delivered by missiles, bombs, spray and cluster spray .
