Ethchlorvynol
Ethchlorvynol is only found in individuals that have used or taken this drug. It is a sedative and hypnotic drug. It has been used to treat insomnia, but has been largely superseded and is only offered where an intolerance or allergy to other drugs exists. [Wikipedia]Although the exact mechanism of action is unknown, ethchlorvynol appears to depress the central nervous system in a manner similar to that of barbiturates. Barbiturates bind at a distinct binding sites associated with a Cl- ionopore at the GABAA receptor, increasing the duration of time for which the Cl- ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.

3-Methylglutaconate
3-Methylglutaconic acid is an intermediate (as the CoA thioester) in the leucine degradative pathway as well as the mevalonate shunt, a pathway that links isoprenoid metabolism with mitochondrial acetyl-CoA metabolism (PMID: 7603789). 3-methylglutaconyl-CoA hydratase is involved in the metabolism process of 3-methylglutaconic acid. When present in sufficiently high levels, 3-methylglutaconic acid can act as an acidogen and a metabotoxin. An acidogen is an acidic compound that induces acidosis, which has multiple adverse effects on many organ systems. A metabotoxin is an endogenously produced metabolite that causes adverse health effects at chronically high levels. Chronically high levels of 3-methylglutaconic acid are associated with at least five inborn errors of metabolism including 3-hydroxy-3-methylglutaryl-CoA lyase deficiency, 3-methylglutaconic aciduria type I, 3-methylglutaconic aciduria type III, 3-methylglutaconic aciduria type IV, and guanidinoacetate methyltransferase deficiency (GAMT deficiency). 3-Methylglutaconic acid is an organic acid. Abnormally high levels of organic acids in the blood (organic acidemia), urine (organic aciduria), the brain, and other tissues lead to general metabolic acidosis. Acidosis typically occurs when arterial pH falls below 7.35. In infants with acidosis, the initial symptoms include poor feeding, vomiting, loss of appetite, weak muscle tone (hypotonia), and lack of energy (lethargy). These can progress to heart, liver, and kidney abnormalities, seizures, coma, and possibly death. These are also the characteristic symptoms of the untreated IEMs mentioned above. Many affected children with organic acidemias experience intellectual disability or delayed development. In adults, acidosis or acidemia is characterized by headaches, confusion, feeling tired, tremors, sleepiness, and seizures. 3-Methylglutaconic acid is an intermediate (as the CoA thioester) in the leucine degradative pathway as well as the mevalonate shunt, a pathway that links isoprenoid metabolism with mitochondrial acetyl-CoA metabolism. (PMID: 7603789) 3-Methylglutaconic acid is the major metabolites accumulating in 3-Methylglutaconic aciduria (MGTA). 3-Methylglutaconic acid can induce lipid oxidative damage and protein oxidative. 3-Methylglutaconic acid decreases the non-enzymatic antioxidant defenses in cerebral cortex supernatants to elicit oxidative stress in the cerebral cortex. 3-Methylglutaconic acid can be used for brain damage disease research[1].
