Heterocyclic acids that are derivatives of 4-pyridinecarboxylic acid (isonicotinic acid).
Drugs used to reverse the inactivation of cholinesterase caused by organophosphates or sulfonates. They are an important component of therapy in agricultural, industrial, and military poisonings by organophosphates and sulfonates.
Compounds that contain the radical R2C=N.OH derived from condensation of ALDEHYDES or KETONES with HYDROXYLAMINE. Members of this group are CHOLINESTERASE REACTIVATORS.
Various salts of a quaternary ammonium oxime that reconstitute inactivated acetylcholinesterase, especially at the neuromuscular junction, and may cause neuromuscular blockade. They are used as antidotes to organophosphorus poisoning as chlorides, iodides, methanesulfonates (mesylates), or other salts.
Any chemical species which accepts an electron-pair from a LEWIS BASE in a chemical bonding reaction.
Inorganic compounds that contain nitrogen as an integral part of the molecule.
Salts that melt below 100 C. Their low VOLATILIZATION can be an advantage over volatile organic solvents.
