Disulfiram is a medication used to support the treatment of chronic alcoholism by producing an acute sensitivity to ethanol (drinking alcohol). Disulfiram works by inhibiting the enzyme aldehyde dehydrogenase (specifically the ALDH2 enzyme [3]), causing many of the effects of a hangover to be felt immediately following alcohol consumption.
Disulfiram-alcohol reaction (DAR) is the effect of the interaction in the human body of alcohol drunk with disulfiram or some types of mushrooms. [ 1 ] [ 2 ] The DAR is key to disulfiram therapy that is widely used for alcohol-aversive treatment and management of other addictions (e.g. cocaine [ 3 ] [ 4 ] use).
However, some do not act via inhibition of this enzyme, and instead act via other, poorly elucidated mechanisms. Unlike acetaldehyde dehydrogenase inhibitors and other disulfiram-like drugs, alcohol dehydrogenase inhibitors such as fomepizole (brand name Antizol) inhibit the metabolism of alcohol into acetaldehyde, thereby increasing and ...
The mechanism of action of disulfiram (i.e. acetaldehyde dehydrogenase (ADH) inhibition) is well understood. However, the chemical may also function as a dopamine beta-hydroxylase (DBH) inhibitor. This would lead to an overall increase in dopamine and decrease in norepinephrine, possibly with significant effects on mood, substance use, and ...
It is an enzyme that accepts electrons from electron-transferring flavoprotein in the mitochondrial matrix, and uses these electrons to reduce ubiquinone. [30] This enzyme contains a flavin and a [4Fe–4S] cluster, but, unlike the other respiratory complexes, it attaches to the surface of the membrane and does not cross the lipid bilayer.
The radioactive decay modes of electron capture and internal conversion are known to be slightly sensitive to chemical and environmental effects that change the electronic structure of the atom, which in turn affects the presence of 1s and 2s electrons that participate in the decay process.
The +M effect, also known as the positive mesomeric effect, occurs when the substituent is an electron donating group. The group must have one of two things: a lone pair of electrons, or a negative charge. In the +M effect, the pi electrons are transferred from the group towards the conjugate system, increasing the density of the system.
The loss of electrons from an atom or molecule is called oxidation, and the gain of electrons is reduction. This can be easily remembered through the use of mnemonic devices. Two of the most popular are "OIL RIG" (Oxidation Is Loss, Reduction Is Gain) and "LEO" the lion says "GER" (Lose Electrons: Oxidation, Gain Electrons: Reduction ...
