ALZ-801 is a potent and orally available small-molecule β-amyloid (Aβ) anti-oligomer and aggregation inhibitor, valine-conjugated prodrug of Tramiprosate with substantially improved PK properties and gastrointestinal tolerability compared with the parent compound[1]. ALZ-801 is an advanced and markedly improved candidate for the treatment of alzheimer’s disease[2].
ALZ-801 (oral administration; 172 mg/kg; single dose) exhibits mean AUCt values of 58,758 and 5841 ng/ml.h in plasma and brain, respectively. The ALZ-801: Tramiprosate ratio in plasma and brain is 1.8 and 3.1, respectively in male CD-1 mice[1].
