Valproic acid
Valproic acid (VPA) is considered to be a drug of first choice and one of the most frequently-prescribed antiepileptic drugs worldwide for the therapy of generalized and focal epilepsies, including special epileptic. It is a broad-spectrum antiepileptic drug and is usually well tolerated. Rarely, serious complications may occur in some patients, including hemorrhagic pancreatitis, coagulopathies, bone marrow suppression, VPA-induced hepatotoxicity and encephalopathy, but there is still a lack of knowledge about the incidence and occurrence of these special side effects. VPA has been approved for stabilization of manic episodes in patients with bipolar disorder. It is also used to treat migraine headaches and schizophrenia. As the use of VPA increases, the number of both accidental and intentional exposures increases. This is paralleled by more reports of VPA-induced toxicity. VPA is relatively contraindicated in pregnancy due to its teratogenicity. It is a known folate antagonist, which can cause neural tube defects. Thus, folic acid supplements may alleviate teratogenic problems. Women who become pregnant whilst taking valproate should be counselled as to its risks. VPA is an inhibitor of the enzyme histone deacetylase 1 (HDAC1). HDAC1 is needed for HIV to remain in infected cells. Patients treated with valproic acid in addition to highly active antiretroviral therapy (HAART) showed a median 75\\% reduction in latent HIV infection. VPA is believed to affect the function of the neurotransmitter GABA (as a GABA transaminase inhibitor) in the human brain. Valproic Acid dissociates to the valproate ion in the gastrointestinal tract.

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.

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.

Methylglutamic acid can be found in tamarind, which makes methylglutamic acid a potential biomarker for the consumption of this food product. N-Methyl-L-glutamic acid (methylglutamate) is a chemical derivative of glutamic acid in which a methyl group has been added to the amino group. It is an intermediate in methane metabolism. Biosynthetically, it is produced from methylamine and glutamic acid by the enzyme methylamine—glutamate N-methyltransferase. It can also be demethylated by methylglutamate dehydrogenase to regenerate glutamic acid .
