5-Hydroxyindoleacetic acid
5-Hydroxyindoleacetic acid, also known as 5-hydroxyindole-3-acetate or 5-HIAA, belongs to the class of organic compounds known as indole-3-acetic acid derivatives. Indole-3-acetic acid derivatives are compounds containing an acetic acid (or a derivative) linked to the C3 carbon atom of an indole. 5-Hydroxyindoleacetic acid exists in all living organisms, ranging from bacteria to humans. In humans, 5-hydroxyindoleacetic acid is a breakdown product of serotonin that is excreted in the urine and it also participates in a number of enzymatic reactions. 5-hydroxyindoleacetic acid can be biosynthesized from 5-hydroxyindoleacetaldehyde; which is catalyzed by the mitochondrial enzyme aldehyde dehydrogenase. In addition, 5-hydroxyindoleacetic acid and S-adenosylmethionine can be converted into 5-methoxyindoleacetate and S-adenosylhomocysteine through its interaction with the enzyme acetylserotonin O-methyltransferase. 5-Hydroxyindoleacetic acid is also involved in the metabolism of tryptophan. 5-Hydroxyindoleacetic acid has been found to be associated with several human diseases such as brunner syndrome, friedreichs ataxia, schizophrenia, and olivopontocerebral atrophy; 5-hydroxyindoleacetic acid has also been linked to the inborn metabolic disorder sepiapterin reductase deficiency. Elevated levels of 5-hydroxyindoleacetic acid in urine (>20 uM) are indicative of appendicitis and gastroenteritis (PMID: 11462886). Serotonin and 5-Hydroxyindoleacetic acid are produced in excess amounts by carcinoid tumors, and levels of these substances may be measured in the urine to test for carcinoid tumors (NCI). 5-Hydroxyindoleacetic acid has also been found to be a product of human gut microbiota. 5-Hydroxyindoleacetic acid (5-HIAA) is the main metabolite of serotonin in the human body. In chemical analysis of urine samples, 5-HIAA is used to determine the bodys levels of serotonin. 5-Hydroxyindole-3-acetic acid is found in many foods, some of which are pitanga, dandelion, coconut, and white cabbage. 5-Hydroxyindole-3-acetic acid is the main metabolite of serotonin or metanephrines, which can be used as a biomarker of neuroendocrine tumors.

Isosorbide Mononitrate
Isosorbide mononitrate (ISMN), sold under the names Imdur and Monoket, among others, is an organic nitrate used principally in the prophylactic treatment of angina pectoris (ischemic chest pain). ISMN is an active metabolite of isosorbide dinitrate and exerts qualitatively similar effects. Like other organic nitrates, ISMN acts as a prodrug for its active metabolite, nitric oxide, which mediates the therapeutic action of ISMN. Nitric oxide works on both arteries and veins, but predominantly veins. Nitric oxide functions by relaxing veins and reducing the central venous pressure, thereby causing venous pooling and a decrease in the venous return to the heart, thus decreasing cardiac preload (PMID: 31643263). The net effect when administering ISMN is therefore a reduced workload for the heart and an improvement in the oxygen supply/demand balance of the myocardium. ISMN is not subject to first pass metabolism in the human liver. Detectable metabolites include isosorbide, sorbitol, and 2-glucuronide of mononitrate, which are pharmacologically inactive (PMID: 1449102). Research on ISMN as a cervical ripener to reduce time at hospital to birth is supportive (PMID: 23983763). Isosorbide mononitrate is only found in individuals who have consumed or used this drug.

5-Phenyl-1,3-oxazinane-2,4-dione
5-Phenyl-1,3-oxazinane-2,4-dione is a metabolite of felbamate. Felbamate (marketed under the brand name Felbatol by MedPointe) is an anti-epileptic drug used in the treatment of epilepsy. It is used to treat partial seizures (with and without generalization) in adults and partial and generalized seizures associated with Lennox-Gastaut syndrome in children. However, an increased risk of potentially fatal aplastic anemia and/or liver failure limit the drugs usage to severe refractory epilepsy. (Wikipedia)

gamma-Carboxyglutamic acid
Carboxyglutamic acid (or the conjugate base, carboxyglutamate), is an uncommon amino acid introduced into proteins by a post-translational carboxylation of glutamic acid residues. This modification is found, for example, in clotting factors and other proteins of the coagulation cascade. This modification introduces an affinity for calcium ions. In the blood coagulation cascade, Vitamin K is required to introduce gamma-carboxylation of clotting factors II, VII, IX, X and protein Z.
