Homotaurine was investigated in a
Homotaurine is currently in a phase 3 study with expected FDA approval as the first disease modifying drug for AD.[7][8]
Medical use
Acamprosate (N-acetyl homotaurine) was approved by the FDA in 2004 to treat alcohol dependence.[4]
Biochemical properties
In preclinical studies it had been found to bind to soluble
Homotaurine has been reported as a
In a human study homotaurine selectively and fully inhibits the formation of Aβ42 oligomers at the clinical dose, without evidence of vasogenic edema.[7]
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.[17]
