"The ANAVEX 1-41 results highlighted in this important paper clearly demonstrate the compound's efficacy, which can be attained at extremely low doses, giving us confidence in the likely clinical profile. Furthermore, it highlights the potential for this compound as a therapeutic solution in the fight against Alzheimer's disease," said Dr. Vamvakides, Chief Scientific Officer of ANAVEX. "If the results we have achieved in a mouse model are duplicated in human clinical trials we believe that ANAVEX could launch a novel drug for Alzheimer's with disease-modifying potential through an anti-amnesic and neuroprotective effect. ANAVEX 1-41 may be able to reverse memory and learning deficits and protect nerve cells from death. This is very different from the symptom-alleviating therapies currently on the market."
A significant factor behind the efficacy of ANAVEX 1-41 is that it can attain synergistic activation of both muscarinic and sigma-1 receptors at extremely low doses in-vivo (0.1 mg/kg i.p.), as evidenced in late pre-clinical studies using a validated mouse model of Alzheimer's disease. This is the first time these results have been achieved by any pharmacological agent in this non-transgenic Alzheimer's mouse model, which is created by injecting amyloid-beta (25-35) peptide into mouse brains to bring on histological and biochemical changes, oxidative stress and learning deficits.
The paper describes the exceptional neuroprotective and anti-amnesic benefits of ANAVEX 1-41, one of the company's lead compounds targeting Alzheimer's disease. Results achieved in pre-clinical studies to date suggest that ANAVEX 1-41 offers disease-modifying potential through its ability to reverse memory and learning deficits and protect nerve cells from death. Importantly, pre-clinical results also underscore the compound's ability to prevent oxidative stress induced by Alzheimer's disease and block apoptosis of neuronal cells through the expression of the caspase-3 enzyme.
The company expects that pre-clinical trials on ANAVEX 1-41 will be complete in early 2009. ANAVEX 1-41 and ANAVEX 2-73, which share a common chemical origin and similarities in their mechanism of action (congeners), are two novel compounds developed by ANAVEX to target Alzheimer's disease. Both compounds show neuroprotective potential and synergistic effects on muscarinic and sigma-1 receptors at extremely low doses, potentially conveying attractive tolerability profiles in addition to their efficacy. ANAVEX has completed pre-clinical testing in mice on ANAVEX 2-73 and expects Phase 1 human clinical trials to begin in 2009. ...http://www.medicalnewstoday.com

Anavex Life Sciences Corp. ("ANAVEX") (OTCBB: AVXL), a biopharmaceutical company engaged in the discovery and development of novel therapeutics to treat Central Nervous System (CNS) diseases and cancer, announces that the anti-amnesic and neuroprotective effects of ANAVEX 1-41 are detailed in a paper published in the current edition of Neuropsychopharmacology. Currently in the late pre-clinical stage, ANAVEX 1-41 is one of the company's lead compounds for Alzheimer's disease (AD). Neuropsychopharmacology is an international scientific journal and the official publication of the American College of Neuropsychopharmacology, which focuses on clinical and basic science contributions that advance our understanding of the brain and behaviour.
