Tramiprosate (Synonyms: Homotaurine, NC 531, NC 758, NSC 77071, 3-Sulfopropylamine)

Tramiprosate is a small, orally-administered compound that binds to soluble Aβ and reduces amyloid aggregation and subsequent depositiontarget: AβIn vitro: Tramiprosate provides neuroprotection against Aβ-induced neurotoxicity in neuronal and mouse organotypic hippocampal cultures, and reverses Aβ-induced long-term potentiation (LTP) inhibition in rat hippocampus, in part, through activation of β-aminobutyric acid A (GABA-A) receptors. Tramiprosate dose-dependently provides neuroprotection against ischemic stroke.In vivo: Tramiprosate produced dose-dependent reductions of Aβ in the brain of transgenic mice (hAPP-TgCRND8). Clinical studies show that tramiprosate was safe and tolerable. In mild-to-moderate AD patients tramiprosate also reduced Aβ42 levels in CSF.The reference for animal administration is 50 mg/kg.
