Metadoxine is an ion pair salt of pyridoxine and pyrrolidone carboxylate (PCA). [1] Pyridoxine (vitamin B 6 ) is a precursor of coenzymes including pyridoxal 5’-phosphate (PLP), which accelerates the metabolic degradation of ethanol and prevents adenosine triphosphate (ATP) inactivation by acetaldehyde .
Carboxylate ion Acrylate ion. In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO) n, where M is a metal and n is 1, 2,....
Carboxylic acids react with bases to form carboxylate salts, in which the hydrogen of the hydroxyl (–OH) group is replaced with a metal cation. For example, acetic acid found in vinegar reacts with sodium bicarbonate (baking soda) to form sodium acetate, carbon dioxide, and water: CH 3 COOH + NaHCO 3 → CH 3 COO − Na + + CO 2 + H 2 O

The permeation rate of sodium through the sodium channel is determined by a four carboxylate residues, the EEDD motif, which make up the outer charged ring. [52] The protonation of these carboxylates is one of the main drivers of proton block in sodium channels, although there are other residues that also contribute to pH sensitivity. [53]
It can cause a black tongue and black stools in some users of the drug when it combines with trace amounts of sulfur in saliva and the colon to form bismuth sulfide. [7] Bismuth sulfide is a highly insoluble black salt, and the discoloration seen is temporary and harmless. Long-term use (more than six weeks) may lead to accumulation and ...
Transition metal salts, especially copper compounds, [9] facilitate decarboxylation via carboxylate complex intermediates. Metals that catalyze cross-coupling reactions thus treat aryl carboxylates as an aryl anion synthon; this synthetic strategy is the decarboxylative cross-coupling reaction. [10]
Docusate is the common chemical and pharmaceutical name of the anion bis(2-ethylhexyl) sulfosuccinate, also commonly called dioctyl sulfosuccinate (DOSS). [2] [3] [4]Salts of this anion, especially docusate sodium, are widely used in medicine as an emollient laxative and as stool softeners, by mouth or rectally. [1]
