Anavex Reports ANAVEX 2-73 Blocks Tau and Amyloid-Beta Proteins in a Preclinical Model of Alzheimer's Disease
Tangui Maurice, PhD, CNRS Research Director, Head of Team 2 'Endogenous Neuroprotection in Neurodegenerative Diseases', at the University of Montpellier and INSERM, and one of the study authors, said, "ANAVEX 2-73 also dose-dependently reduced C99 levels in the hippocampus, an effect which researchers are currently trying to achieve with BACE inhibitors. In the mouse model we also confirmed the central role of the kinase GSK-3 beta in Alzheimer's disease toxicity through drugs acting either directly as GSK-3 beta inhibitors, or indirectly, as mixed muscarinic and Sigma-1 ligands. Both can efficiently alleviate these two major alterations observed in the Alzheimer's animal model, as well as in Alzheimer's patient brains. However, by targeting GSK-3 beta indirectly as ANAVEX 2-73 does through muscarinic and Sigma-1 ligands, we could avoid the toxicity seen by directly targeting GSK-3 beta."
Christopher U. Missling, PhD, President and Chief Executive Officer of Anavex, said, "Using further upstream targets that efficiently block tau phosphorylation and amyloid overproduction might be a more comprehensive approach in successfully treating this complex disease. Together with previously confirmed findings demonstrating the ability of ANAVEX 2-73 to reduce mitochondrial oxidative stress, this publication strengthens the case for a potential pharmacological treatment for Alzheimer's disease."
The report, entitled "Blockade of Tau Hyperphosphorylation and Amyloid-beta1-42 Generation by the Aminotetrahydrofuran Derivative ANAVEX2-73, a Mixed Muscarinic and Sigma-1 Receptor Agonist, in a Nontransgenic Mouse Model of Alzheimer's Disease," is based on a scientific study conducted in France at the University of Montpellier and INSERM.
The study was jointly conducted by Valentine Lahmy, Johann Meunier, Susanna Malmstro, Gaelle Naert, Laurent Givalois, Seung Hyun Kim, Vanessa Villard, Alexandre Vamvakides and Tangui Maurice. The full paper is available on the Anavex website at http://anavex.com/publications.html.
