What is 3-Amino-1-propanesulfonic acid?
Description
Homotaurine (also known as tramiprosate (INN), 3-amino-1-propanesulfonic acid, or 3-APS) is a natural sulfonic acid found in seaweed. Tramiprosate is a sulfated glycosaminoglycan mimetic that was reported to bind soluble Aβ and inhibit the interaction of Aβ with endogenous glycosaminoglycans, thereby preventing β-sheet formation. Conversely, tramiprosate was also reported to promote tau polymerization into fibrillar aggregates. It is also an analog of GABA that can act as a partial agonist of GABAA receptors, as well as an antagonist at GABAB receptors.

The Uses of 3-Amino-1-propanesulfonic acid
3-Amino-1-propanesulfonic acid is a Important gabamimetic agent-evokes neurological responses similar to those elicited by γ-aminobutyric acid (GABA). It is an intermediate in the synthesis of acamprosate. acamprosate is an alcohol addiction treatment commonly used to reduce urges to drink and help people in recovery remain sober.
What are the applications of Application
Tramiprosate is a sulfated glycosaminoglycan mimic that targets amyloid β
Definition
ChEBI: 3-Aminopropanesulfonate is an organosulfonic acid.
Biological Activity
Sulfated glycosaminoglycan (sGAG) mimetic that targets soluble amyloid β (A β ) and maintains A β in a non-fibrillar form. Decreases A β 42-induced neuronal death and inhibits amyloid deposition in vitro . Decreases brain amyloid plaque load by 30%, increases tau polymerization and is brain penetrant. Also a GABA analog that protects against the convulsant and cytotoxic activity of kainic acid in vivo .
