Sulfonic acids

Taurine (; IUPAC: 2-aminoethanesulfonic acid) is a naturally occurring organic compound with the chemical formula in its non-zwitterionic form and in its zwitterionic form, and is a non-proteinogenic amino sulfonic acid widely distributed in mammalian tissues and organs. Structurally, by containing a sulfonic acid group instead of a carboxylic acid group, it is not involved in protein synthesis but is still usually referred to as an amino acid. As non-proteinogenic amino sulfonic acid, it is not encoded by the genetic code and is distinguished from the protein-building α-amino acids.

Acamprosate, sold under the brand name Campral, is a medication which reduces cravings in alcoholism. It is thought to stabilize chemical signaling in the brain that would otherwise be disrupted by alcohol withdrawal. When used alone, acamprosate is not an effective therapy for alcohol use disorder in most individuals, as it only addresses withdrawal symptoms and not psychological dependence. It facilitates a reduction in alcohol consumption as well as full abstinence when used in combination with psychosocial support or other drugs that address the addictive behavior.

Docusate is the common chemical and pharmaceutical name of the anion bis(2-ethylhexyl) sulfosuccinate, also commonly called dioctyl sulfosuccinate (DOSS).

HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a zwitterionic sulfonic acid buffering agent. It is one of the twenty Good's buffers. HEPES is widely used in cell culture, largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by aerobic respiration) when compared to bicarbonate buffers, which are also commonly used in cell culture. Lepe-Zuniga et al. reported an unwanted photochemical process wherein HEPES catalyzes a reaction with riboflavin when exposed to ambient light to produce hydrogen peroxide. This is not a

In biochemistry, ABTS ('''2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)''') is a chemical compound used to observe the reaction kinetics of specific enzymes. A common use for it is in the enzyme-linked immunosorbent assay (ELISA) to detect the binding of molecules to each other.

MOPS ('3-(N-morpholino)propanesulfonic acid') is a buffer introduced in the 1960s, one of the twenty Good's buffers. It is a structural analog to MES, and like MES, its structure contains a morpholine ring. HEPES is a similar pH buffering compound that contains a piperazine ring. With a pKa of 7.20, MOPS is an excellent buffer for many biological systems at near-neutral pH.

chemical compound

Homotaurine, also known as tramiprosate (INN), 3-amino-1-propanesulfonic acid, or 3-APS, is a natural sulfonic acid found in seaweed. It is analogous to taurine, but with an extra carbon in its chain. It has GABAergic activity, apparently by mimicking GABA, which it resembles.

chemical compound

Sulfoquinovose, also known as 6-sulfoquinovose and 6-deoxy-6-sulfo-D-glucopyranose, is a monosaccharide sugar that is found as a building block in the sulfolipid sulfoquinovosyl diacylglycerol (SQDG). Sulfoquinovose is a sulfonic acid derivative of glucose, the sulfonic acid group is introduced into the sugar by the enzyme UDP-sulfoquinovose synthase (SQD1). Sulfoquinovose is degraded through a metabolic process termed sulfoglycolysis. The half-life for mutarotation of sulfoquinovose at pD 7.5 and 26C is 299 minutes.

Mafosfamide (INN; development code ASTA-Z-7557) is an oxazaphosphorine (cyclophosphamide-like) alkylating agent under investigation as a chemotherapeutic. It is metabolized by cytochrome P450 into 4-hydroxycyclophosphamide, which is then converted into aldophosphamide, which, in turn yields the cytotoxic metabolites phosphoramide mustard and acrolein.

Ecamsule (USAN, trade name Mexoryl SX, INCI terephthalylidene dicamphor sulfonic acid) is an organic compound which is added to many sunscreens to filter out UVA rays. It is a benzylidene camphor derivative, many of which are known for their excellent photostability.

chemical compound

Saclofen is a competitive antagonist for the GABAB receptor. This drug is an analogue of the GABAB agonist baclofen. The GABAB receptor is heptahelical receptor, expressed as an obligate heterodimer, which couples to the Gi/o class of heterotrimeric G-proteins. The action of saclofen on the central nervous system is understandably modest, because G-proteins rely on an enzyme cascade to alter cell behavior while ionotropic receptors immediately change the ionic permeability of the neuronal plasma membrane, thus changing its firing patterns. These particular receptors, presynaptically inhibit N-

'''N-Methyltaurine (2-methylaminoethanesulfonic acid') is an aminosulfonic acid which is present as a zwitterion in the crystalline state and in polar solvents (just like amino acids). In contrast to the widespread taurine, N''-methyltaurine has been found in nature only in red algae, where it is formed by methylation of taurine. It is an important industrial chemical used in the production of taurates, which are used extensively as mild anionic surfactants.
