Description | Tramiprosate, also known as 3APS or tramiprosic acid, belongs to the class of organic compounds known as organosulfonic acids. Organosulfonic acids are compounds containing the sulfonic acid group, which has the general structure RS(=O)2OH (R is not a hydrogen atom). Homotaurine has been reported as a GABA antagonist, as well as a GABA agonist. Tramiprosate is a very strong basic compound (based on its pKa). Acamprosate was approved by the FDA in 2004 to treat alcohol dependence. It is analogous to taurine, but with an extra carbon in its chain. In vitro studies have found that homotaurine is a GABAA partial agonist as well as a GABAB receptor partial agonist with low efficacy, becoming an antagonist and a displacing full agonist of GABA or baclofen at this receptor. In preclinical studies it had been found to bind to soluble amyloid beta and inhibit the formation of neurotoxic aggregates. One study in rats showed that homotaurine suppressed ethanol-stimulated dopamine release, as well as ethanol intake and preference in rats in a way similar to the N-acetyl derivative of homotaurine, acamprosate. Homotaurine has also shown anticonvulsant activities, reduction in skeletal muscle tonus, and hypothermic activity. It has GABAergic activity, apparently by mimicking GABA, which it resembles. In a study in rats, homotaurine reversed the catatonia induced by baclofen (the prototypical GABAB agonist), and was able to produce analgesia via the GABAB receptor, an effect that was abolished when CGP-35348, a GABAB receptor antagonist was applied. Homotaurine was investigated in a Phase III clinical trial as a potential treatment for Alzheimer's disease that did not show efficacy. A study in cognitive impairment done in 2018 did show positive benefits. This compound has been identified in human blood as reported by (PMID: 31557052 ). Tramiprosate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Tramiprosate is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. |
