VX is an odorless and tasteless chiral organophosphorous chemical with a molecular weight of When weaponized, it can be dispersed as a liquid, aerosol, or as a mixture with a clay or talc in the form of a thickened agent.

VX is an acetylcholinesterase inhibitor. Normally, when a motor neuron is stimulated, it releases the neurotransmitter acetylcholine ACh into the space between the neuron and an adjacent muscle cell, the synaptic cleft.

When acetylcholine is taken up by the muscle cell, it stimulates muscle contraction. To avoid a state of constant muscle contraction, the acetylcholine is then broken down hydrolysed into the inactive substances acetic acid and choline by AChE.

VX blocks the action of AChE, resulting in an accumulation of acetylcholine in the space between the neuron and muscle cell.

On a molecular level, this leads to the ongoing stimulation and eventual fatigue of all affected muscarinic and nicotinic ACh receptors.

This results in initial violent contractions, followed by "sustained supercontraction restricted to the fluid sarcoplasm of the subjunctional endplate and prolonged, depolarizing neuromuscular blockade.

The extreme toxicity of VX is partly due to the fact that the inhibitor was designed to be an excellent structural mimic for the transition state of the natural substrate acetylcholine of acetylcholinesterase.

VX has a very high "on-rate" to react with the target enzyme and form a stable P-O-C bond phosphorylation. Aging is a time-dependent side reaction loss of an alkoxyl group that occurs on nerve agents after phosphonylation and renders the nerve agent-acetylcholinesterase complex highly resistant to regeneration by any known antidote.

Slower aging by VX suggests it should be possible to develop more effective antidotes and treatments. The reaction products of acetylcholinesterase with VX before and after the "aging" reaction were solved near atomic resolution by X-ray crystallography to aid in antidote development.

The structural kinetic of phosphonylation followed by aging also showed an unexpected conformational change in the catalytic triad suggestive of an "induced fit" between the VX molecule and acetylcholinesterase.

VX is chiral at its phosphorus atom. VX is produced via the transester process , which gives a racemic mixture of the two enantiomers.

This entails a series of steps whereby phosphorus trichloride is methylated to produce methyl phosphonous dichloride. The resulting material is reacted with ethanol to form a diester.

This is then transesterified with N , N -diisopropylaminoethanol to produce the mixed phosphonite. Finally, this immediate precursor is reacted with sulfur to form VX.

VX can also be delivered in binary chemical weapons which mix in-flight to form the agent prior to release.

It may also be produced by mixing with sulfur compounds, as with the liquid dimethyl polysulfide mixture Agent NM in the canceled XM 8-inch projectile program.

Like other organophosphorus nerve agents, VX may be destroyed by reaction with strong nucleophiles.

The reaction of VX with concentrated aqueous sodium hydroxide results in two competing solvolysis reactions: cleavage of either the P—O or P—S esters.

Although the P—S cleavage is the dominant pathway, the product of P—O bond cleavage is the toxic phosphonic thioester EA and both reactions are slow.

Early symptoms of percutaneous exposure skin contact include local sweating and muscular twitching at the area of exposure, followed by nausea or vomiting.

Miosis pinpointing of the pupils may be an early sign of agent exposure, but is not usually used as the only indicator of exposure.

VX is a "particularly toxic nerve agent". The potentially fatal dose is only slightly higher than the dose having any effect at all, and the effects of a fatal dose are so rapid that there is little time for treatment.

When treating VX exposure, primary consideration is given to removal of the liquid agent from the skin, before removal of the individual to an uncontaminated area or atmosphere.

After this, the victim is decontaminated by washing the contaminated areas with household bleach and flushing with clean water, followed by removal of contaminated clothing and further skin decontamination.

When possible, decontamination is completed before the casualty is taken for further medical treatment. Atropine blocks a subset of acetylcholine receptors known as muscarinic acetylcholine receptors mAchRs , so that the buildup of acetylcholine produced by loss of the acetylcholinesterase function has a reduced effect on their target receptor.

The serum level of ethyl methylphosphonic acid EMPA , a VX hydrolysis product, was measured to confirm exposure in one poisoning victim. There also exist procedures for determination of VX hydrolysis products in urine and of VX adducts to albumin in blood.

The chemists Ranajit Ghosh and J. Further commercial research on similar compounds ceased in when its lethality to humans was discovered. The U. The discovery occurred when the chemists were investigating a class of organophosphate compounds organophosphate esters of substituted aminoethanethiols.

In , ICI put one of them on the market under the trade name Amiton. It was subsequently withdrawn, as it was too toxic for safe use. The toxicity did not go unnoticed, and samples of it were sent to the British Armed Forces research facility at Porton Down for evaluation.

After the evaluation was complete, several members of this class of compounds became a new group of nerve agents, the V agents. The name is a contraction of the words "venomous agent X".

Van M. Sim underwent an intravenous infusion of VX to evaluate its effects and to establish a baseline for future experimentation.

After approximately 3. The experiment was immediately terminated to preserve his life. In their conclusion, the researchers estimated that 2.

There was evidence of a combination of chemical agents having been used by Iraq against the Kurds in the Halabja chemical attack in under Saddam Hussein , including VX.

After U. Two people were injured and one year-old man died, who was the first victim of VX ever documented in the world at that time.

He chased them for about 90 metres yd before collapsing, dying ten days later without ever coming out of a deep coma.

Doctors in the hospital suspected at the time he had been poisoned with an organophosphate pesticide, but the cause of death was pinned down only after cult members arrested for the subway attack confessed to the killing.

Metabolites of VX such as ethyl methylphosphonate, methylphosphonic acid and diisopropyl methylthio ethylamine were later found in samples of the victim's blood seven months after his murder.

According to the authorities he was murdered by poisoning with VX which was found on his face. Chemical weapons experts later suggested that the widely used fonofos organophosphate insecticide could have been mistaken for EMPTA.

In , the U. Early disposal included the U. Eric G. Worldwide, VX disposal has continued since under the mandate of the Chemical Weapons Convention.

When the convention entered force, the parties declared worldwide stockpiles of 19, tonnes 21, short tons of VX. In fiscal year , the U.

VX was hydrolyzed to much less toxic byproducts by using concentrated caustic solution, and the resulting waste was then shipped off-site for further processing.

Technical and political issues regarding this secondary byproduct resulted in delays, but the depot completed their VX stockpile destruction in August The remaining VX stockpile in the U.

The program was established as an alternative to the incineration process successfully used by the Army Chemical Materials Agency , which completed its stockpile destruction activities in March The Blue Grass Pilot Plant has been plagued by repeated cost over-runs and schedule slippages since its inception.

In Russia, the U. The new facility, which opened in May , has been working on eliminating the nearly 5, tonnes 5, short tons of nerve agents held at the former storage complex.

One of the best-known references to VX in popular culture is its use in the film The Rock , [60] [61] which centers on a threatened VX attack on San Francisco from the island of Alcatraz.

The film uses artistic license , notably with VX being ascribed corrosive powers it does not possess, permitting an early scene in which a VX victim is shown with his face melting, rather than dying through asphyxiation.

Other references to VX are found in the film It's a Disaster in which it is revealed that a nearby dirty bomb attack was in fact a VX attack, prompting the three couples to contemplate a suicide pact, as well as the film Mission: Impossible — Rogue Nation , where in the beginning scene Ethan Hunt steals VX nerve gas from Chechen Separatists on their way to Syria.

Also the TV series 24 season 5 has a similar storyline. In the video game Everybody's Gone to the Rapture , VX is alluded to as a nerve agent used by the government to contain a pattern which infects and kills humans and other animals.

Archived from the original on In the 21st century, Novichok agents came to public attention after they were used to poison opponents of the Russian government, including the Skripals and two others in Amesbury, UK and Alexei Navalny Novichok agents were designed to achieve four objectives: [14] [15].

Some of these agents are binary weapons , in which precursors for the nerve agents are mixed in a munition to produce the agent just prior to its use.

The precursors are generally significantly less hazardous than the agents themselves, so this technique makes handling and transporting the munitions a great deal simpler.

Additionally, precursors to the agents are usually much easier to stabilise than the agents themselves, so this technique also makes it possible to increase the shelf life of the agents.

This has the disadvantage that careless preparation may produce a non-optimal agent. During the s and s, binary versions of several Soviet agents were developed and are designated as "Novichok" agents.

It was unanimously confirmed by four laboratories around the world, according to the OPCW. The Russian government denies producing or researching agents "under the title Novichok".

Novichok has been known to most western secret services since the s, [24] and in Iranian chemists working at a university in Tehran synthesised five of the seven Novichok agents for analysis and produced detailed mass spectral data which was added to the OPCW's Central Analytical Database.

The Soviet Union and Russia reportedly developed extremely potent fourth-generation chemical weapons from the s until the early s, according to a publication by two chemists, Lev Fyodorov and Vil Mirzayanov in Moskovskiye Novosti weekly in According to Mirzayanov, the Russian Military Chemical Complex MCC was using defence conversion money received from the West for development of a chemical warfare facility.

He was the head of a counter-intelligence department and performed measurements outside the chemical weapons facilities to make sure that foreign spies could not detect any traces of production.

To his horror, the levels of deadly substances were eighty times greater than the maximum safe concentration. The Prosecutor-General of Russia effectively admitted the existence of Novichok agents when he brought a treason case against Mirzayanov.

According to expert witness testimonies that three scientists prepared for the KGB , Novichok and other related chemical agents had indeed been produced and therefore Mirzayanov's disclosure represented high treason.

Mirzayanov was arrested on 22 October and sent to Lefortovo prison for divulging state secrets. He was released later because "not one of the formulas or names of poisonous substances in the Moscow News article was new to the Soviet press, nor were locations Hoffman for The Washington Post the chemist claimed that he helped invent the A agent, that it was more frostproof, and confirmed that a binary version has been developed from it.

Unlike the interview twenty years earlier, he denied any binary agents were developed successfully, at least up until his involvement in the research ceased in The chemical formula was given to Western NATO countries, who synthesized it then used small amounts to test protective equipment, detection of it, and antidotes to it.

Novichok was referred to in a patent filed in for an organophosphorus poisoning treatment. The University of Maryland, Baltimore research was part-funded by the U.

Professor Leonid Rink , who said he had participated in the creation of Novichok agents, [39] confirmed that the structures leaked by Mirzayanov were the correct ones.

David Wise , in his book Cassidy's Run , implies that the Soviet program may have been the unintended result of misleading information, involving a discontinued American program to develop a nerve agent code named " GJ ", that was fed by a double agent to the Soviets as part of Operation Shocker.

Since its independence in , Uzbekistan has been working with the government of the United States to dismantle and decontaminate the sites where the Novichok agents and other chemical weapons were tested and developed.

In May , the Irish Independent reported that " Germany 's foreign intelligence service secured a sample of the Soviet-developed nerve agent Novichok in the s and passed on its knowledge to partners including Britain and the US, according to German media reports.

Mirzayanov provided the first description of these agents. A binary agent was then created that would mimic the same properties but would either be manufactured using materials which are not controlled substances under the CWC , [34] or be undetectable by treaty regime inspections.

The first Novichok series compound was in fact the binary form of a known V-series nerve agent, VR , [62] while the later Novichok agents are the binary forms of compounds such as A and A According to a classified secret report by the US Army National Ground Intelligence Center in Military Intelligence Digest dated 24 January , [64] agent designated A and its ethyl analogue A developed under the Foliant programme "are as toxic as VX, as resistant to treatment as soman, and more difficult to detect and easier to manufacture than VX".

The binary versions of the agents reportedly use acetonitrile and an organic phosphate "that can be disguised as a pesticide precursor. The agent A is also supposedly around five to eight times more potent than VX.

Making the median lethal dose for inhaled A 0. The agents are reportedly capable of being delivered as a liquid, aerosol or gas via a variety of systems, including artillery shells, bombs, missiles and spraying devices.

Mirzayanov gives somewhat different structures for Novichok agents in his autobiography than those which have been identified by Western experts.

Mirzyanov makes clear that a large number of compounds were made, and many of the less potent derivatives were reported in the open literature as new organophosphate insecticides, [68] so that the secret chemical weapons program could be disguised as legitimate pesticide research.

According to chemical weapons expert Jonathan Tucker , the first binary formulation developed under the Foliant programme was used to make Substance 33 VR , very similar to the more widely known VX , differing only in the alkyl substituents on its nitrogen and oxygen atoms.

A wide range of potential structures have been reported. The organic groups are subject to more variety; however, a common substituent is phosgene oxime or analogues thereof.

This is a potent chemical weapon in its own right, specifically as a nettle agent , and would be expected to increase the harm done by the Novichok agent.

Many claimed structures from this group also contain cross-linking agent motifs which may covalently bind to the acetylcholinesterase enzyme's active site in several places, perhaps explaining the rapid denaturing of the enzyme that is claimed to be characteristic of the Novichok agents.

The model predicted a tight fit with high binding affinity and formation of a covalent bond to a serine residue in the active site, with a similar binding mode to established nerve agents such as sarin and soman.

According to Vladimir Uglev, who headed a group that worked on the development of the Novichok agents, [41] at least one liquid form of Novichok is very stable with a slow evaporation rate and can remain potent for possibly up to 50 years.

As nerve agents, the Novichok agents belong to the class of organophosphate acetylcholinesterase inhibitors. These chemical compounds inhibit the enzyme acetylcholinesterase , preventing the normal breakdown of the neurotransmitter acetylcholine.

Acetylcholine concentrations then increase at neuromuscular junctions to cause involuntary contraction of all skeletal muscles cholinergic crisis.

This then leads to respiratory and cardiac arrest as the victim's heart and diaphragm muscles no longer function normally and finally death from heart failure or suffocation as copious fluid secretions fill the victim's lungs.

As can be seen with other organophosphate poisonings, Novichok agents may cause lasting nerve damage, resulting in permanent disablement of victims, according to Russian scientists.

He was critically injured and took ten days to recover consciousness after the incident. He lost the ability to walk and was treated at a secret clinic in Leningrad for three months afterwards.

The agent caused permanent harm, with effects that included "chronic weakness in his arms, a toxic hepatitis that gave rise to cirrhosis of the liver , epilepsy, spells of severe depression, and an inability to read or concentrate that left him totally disabled and unable to work.

The use of a fast-acting peripheral anticholinergic drug such as atropine can block the receptors where acetylcholine acts to prevent poisoning as in the treatment for poisoning by other acetylcholinesterase inhibitors.

Atropine, however, is difficult to administer safely, because its effective dose for nerve agent poisoning is close to the dose at which patients suffer severe side effects, such as changes in heart rate and thickening of the bronchial secretions, which fill the lungs of someone suffering nerve agent poisoning so that suctioning of these secretions, and other advanced life support techniques, may be necessary in addition to administration of atropine to treat nerve agent poisoning.

In the treatment of nerve agent poisoning, atropine is most often administered along with a Hagedorn oxime such as pralidoxime , obidoxime , TMB-4 , or HI-6 , which reactivates acetylcholinesterase which has been inactivated by phosphorylation by an organophosphorus nerve agent and relieves the respiratory muscle paralysis caused by some nerve agents.

Pralidoxime is not effective in reactivating acetylcholinesterase inhibited by some older nerve agents such as soman [74] or the Novichok nerve agents, described in the literature as being up to eight times more toxic than nerve agent VX.

The US Army has funded studies of the use of galantamine along with atropine in the treatment of a number of nerve agents, including soman and the Novichok agents.

There have been differing claims about the persistence of Novichok and binary precursors in the environment.

One view is that it is not affected by normal weather conditions, and may not decompose as quickly as other organophosphates.

However, Mirzayanov states that Novichok decomposes within four months. Russian opposition —linked historians Yuri Felshtinsky and Vladimir Pribylovsky speculated that the murder became "one of the first in the series of poisonings organised by Russia's security services".

The Russian Ministry of Internal Affairs analysed the substance and announced that it was "a phosphorus-based military-grade nerve agent" [82] "whose formula was strictly classified".

Vladimir Khutsishvili, a former business partner of Kivelidi's, was subsequently convicted of the killings. However, Khutsishvili, who claimed that he was innocent, had not been detained at the time of the trial and freely left the country.

He was only arrested in after he returned to Russia, believing that the ten-year old case was closed. After the attack, 21 members of the emergency services and public were checked for possible exposure, and three were hospitalised.

As of 12 March, one police officer remained in hospital. Up to 38 people in Salisbury have been affected by the agent to an undetermined extent. Daniel Gerstein , a former senior official at the U.

Department of Homeland Security , said it was possible that Novichok nerve agents had been used before in Britain to assassinate Kremlin targets, but had not been detected: "It's entirely likely that we have seen someone expire from this and not realised it.

We realised in this case because they were found unresponsive on a park bench. Had it been a higher dose, maybe they would have died and we would have thought it was natural causes.

On 20 March , Ahmet Üzümcü , Director-General of the OPCW, said that it would take "another two to three weeks to finalise the analysis" of samples taken from the poisoning of Skripal.

Experts said that their findings did not challenge the conclusions by UK government: "We provided that information to the Government who have then used a number of other sources to come to the conclusions that they have.

By September two Russian "tourists", " Alexander Petrov " and " Ruslan Boshirov ", had been identified as suspects.

On 28 June it was reported that Sergeyev received instructions from his GRU superior by cell phone on more than ten occasions during his UK visits.

On 30 June , Charlie Rowley and Dawn Sturgess were found unconscious at a house in Amesbury , Wiltshire , about eight miles from the Salisbury poisoning site.

On 8 July , Dawn Sturgess died as a result of the poisoning. The police later closed and fingertip-searched Queen Elizabeth Gardens in Salisbury.

In the aftermath of the Skripal poisoning, investigative journalists were able to track some of the people involved also in Bulgaria [] [].

This is how another suspected poisoning case dating back to April during their stay in the country was linked to the novichok nerve agent. The victim was the Bulgarian arms dealer Emilian Gebrev, who shares two hypotheses why he might have been attacked: The first one links to the fact that his arms manufacturing company Dunarit exports defense equipment to the Ukraine.

The other one relates to an attempt by an offshore company to take over Dunarit. The takeover attempt was ultimately linked to the influential Bulgarian politician and oligarch Delyan Peevski who has historically been funded by Russia's state-owned VTB Bank [].

On 4 September, the North Atlantic Council was briefed by the German representative on the "appalling assassination attempt on" Navalny.

In a post-meeting press conference, Secretary-General Jens Stoltenberg said that NATO allies "agree that Russia has serious questions it must answer", that the OPCW needed to conduct an impartial investigation, that "those responsible for this attack must be brought to justice" and called on Russia to "provide complete disclosure of the Novichok programme to the OPCW.

The Novichok class of agents were reportedly developed in an attempt to circumvent the Chemical Weapons Treaty chemical weapons are banned on the basis of chemical structure and therefore a new chemical agent is not subject to past treaties.

They have reportedly been engineered to be undetectable by standard detection equipment and to defeat standard chemical protective gear Novichok agents may consist of two separate 'non-toxic' components that, when mixed, become the active nerve agent The binary concept—mixing or storing two less toxic chemicals and creating the nerve agent within the weapon—was safer during storage.

VX wurde bis zur Unterzeichnung der Chemiewaffenkonvention , in der die Zerstörung aller Vorräte verlangt wird, auch von den Vereinigten Staaten produziert.

After this, the victim is decontaminated by washing the contaminated areas with household bleach and flushing with clean water, followed by removal of contaminated clothing and further skin decontamination.

When possible, decontamination is completed before the casualty is taken for further medical treatment. Atropine blocks a subset of acetylcholine receptors known as muscarinic acetylcholine receptors mAchRs , so that the buildup of acetylcholine produced by loss of the acetylcholinesterase function has a reduced effect on their target receptor.

The serum level of ethyl methylphosphonic acid EMPA , a VX hydrolysis product, was measured to confirm exposure in one poisoning victim.

There also exist procedures for determination of VX hydrolysis products in urine and of VX adducts to albumin in blood. The chemists Ranajit Ghosh and J.

Further commercial research on similar compounds ceased in when its lethality to humans was discovered. The U. The discovery occurred when the chemists were investigating a class of organophosphate compounds organophosphate esters of substituted aminoethanethiols.

In , ICI put one of them on the market under the trade name Amiton. It was subsequently withdrawn, as it was too toxic for safe use.

The toxicity did not go unnoticed, and samples of it were sent to the British Armed Forces research facility at Porton Down for evaluation.

After the evaluation was complete, several members of this class of compounds became a new group of nerve agents, the V agents.

The name is a contraction of the words "venomous agent X". Van M. Sim underwent an intravenous infusion of VX to evaluate its effects and to establish a baseline for future experimentation.

After approximately 3. The experiment was immediately terminated to preserve his life. In their conclusion, the researchers estimated that 2.

There was evidence of a combination of chemical agents having been used by Iraq against the Kurds in the Halabja chemical attack in under Saddam Hussein , including VX.

After U. Two people were injured and one year-old man died, who was the first victim of VX ever documented in the world at that time. He chased them for about 90 metres yd before collapsing, dying ten days later without ever coming out of a deep coma.

Doctors in the hospital suspected at the time he had been poisoned with an organophosphate pesticide, but the cause of death was pinned down only after cult members arrested for the subway attack confessed to the killing.

Metabolites of VX such as ethyl methylphosphonate, methylphosphonic acid and diisopropyl methylthio ethylamine were later found in samples of the victim's blood seven months after his murder.

According to the authorities he was murdered by poisoning with VX which was found on his face. Chemical weapons experts later suggested that the widely used fonofos organophosphate insecticide could have been mistaken for EMPTA.

In , the U. Early disposal included the U. Eric G. Worldwide, VX disposal has continued since under the mandate of the Chemical Weapons Convention.

When the convention entered force, the parties declared worldwide stockpiles of 19, tonnes 21, short tons of VX. In fiscal year , the U.

VX was hydrolyzed to much less toxic byproducts by using concentrated caustic solution, and the resulting waste was then shipped off-site for further processing.

Technical and political issues regarding this secondary byproduct resulted in delays, but the depot completed their VX stockpile destruction in August The remaining VX stockpile in the U.

The program was established as an alternative to the incineration process successfully used by the Army Chemical Materials Agency , which completed its stockpile destruction activities in March The Blue Grass Pilot Plant has been plagued by repeated cost over-runs and schedule slippages since its inception.

In Russia, the U. The new facility, which opened in May , has been working on eliminating the nearly 5, tonnes 5, short tons of nerve agents held at the former storage complex.

One of the best-known references to VX in popular culture is its use in the film The Rock , [60] [61] which centers on a threatened VX attack on San Francisco from the island of Alcatraz.

The film uses artistic license , notably with VX being ascribed corrosive powers it does not possess, permitting an early scene in which a VX victim is shown with his face melting, rather than dying through asphyxiation.

Other references to VX are found in the film It's a Disaster in which it is revealed that a nearby dirty bomb attack was in fact a VX attack, prompting the three couples to contemplate a suicide pact, as well as the film Mission: Impossible — Rogue Nation , where in the beginning scene Ethan Hunt steals VX nerve gas from Chechen Separatists on their way to Syria.

Also the TV series 24 season 5 has a similar storyline. In the video game Everybody's Gone to the Rapture , VX is alluded to as a nerve agent used by the government to contain a pattern which infects and kills humans and other animals.
