ANAVEX Life Sciences Corp.
(OTCBB: AVXL), a biopharmaceutical company engaged in the discovery and
development of novel therapeutics to treat Central Nervous System (CNS)
diseases and cancer, presented data from the company's novel
compound, ANAVEX 1-41, targeting Alzheimer's disease, at the International
Conference on Alzheimer's Disease (ICAD) 2008, Chicago, USA, July 26 to 31,
2008. The compound has a synergistic neuroprotective and anti-apoptotic
effect in Alzheimer's disease in animal models using amyloid (beta) 25-35
peptide.
"We are pleased by our continued progress in the development of ANAVEX
1-41, and are excited to be presenting data regarding its potent
neuroprotective and anti-apoptotic properties at such low doses at ICAD,"
said Dr. Vamvakides, Chief Scientific Officer of ANAVEX. "Based on our
pre-clinical studies to date, we continue to believe that ANAVEX 1-41 may
offer disease-modifying options that reverse memory and learning deficits
and protect nerve cells from death."
The Anavex Life Sciences presentation is entitled: "Neuroprotective
effects of activators/agonists of the sigma-1 chaperone protein against
amyloid toxicity in a mouse mode". The authors are: Tanguy Maurice (1),

Neuroprotection was attained in the ANAVEX 1-41 compound at very low
doses (0,1mg/kg) in mice. At the same doses there was synergy between
Sigma-1 receptors and Muscarinic receptors, amplifying the anti-amnesic
potential effects, as well as the anti-apoptotic and the anti-oxidative
stress potential.
Neuroprotection is the most important component necessary to attain
long-term benefits in neurodegenerative diseases. In Alzheimer's disease,
neuroprotection is about shielding the neuronal cells in the brain from
degeneration or death. Therefore, ANAVEX's potent neuroprotective compound
may offer disease-modifying treatment and not merely symptomatic relief
from Alzheimer's disease. Moreover, the compound does not target
pathologoanatomic hallmarks, such as amyloid-plaques, whose role has turned
out to be controversial, since approaches to inhibit them have failed to
provide compelling benefit.
Anavex's approach is based on the exploitation of the multiple
modulation properties of Sigma-1 receptors, which are as of yet unexploited
by the existing drugs in the market. Sigma-1 receptors are proteins that
regulate the activity of other different proteins (like IP3 receptors or ER
stress sensors) and also of sodium and calcium channels. Moreover, through
their modulatory role, Sigma-1 receptors are able to regulate cellular
apoptotic processes.
Unlike the challenge of pro-amyloid and anti-amyloid theories of AD,
Anavex Life Sciences' SIGMACEPTOR(TM) Discovery Platform sigma-1 activator
molecules target neuronal intracellular structures with the goal of
preventing neurodegenerative action of disturbed biochemical pathways and
channels.
About Anavex Life Sciences Corp.
Anavex Life Sciences Corp. (anavex) is an emerging
biopharmaceutical company engaged in the discovery and development of novel
drug targets for the treatment of cancer and neurological diseases such as
Alzheimer's, epilepsy and depression. The company's proprietary
SIGMACEPTOR(TM) Discovery Platform involves the rational design of drug
compounds that fulfill specific criteria based on unmet market needs and
new scientific advances. Selected drug candidates demonstrate high,
non-exclusive affinity for sigma receptors, which are involved in the
modulation of multiple cellular biochemical signaling pathways.
ANAVEX's SIGMACEPTOR(TM)-N program involves the development of novel
and original drug candidates that target neurological and neurodegenerative
diseases (Alzheimer's disease, epilepsy, depression, pain). The company's
lead drug candidates exhibit high, non-exclusive affinity for sigma
receptors with strong evidence for anti-amnesic, neuroprotective,
anti-apoptotic, anti-oxidative, anti-inflammatory, anti-convulsive,
anti-depressant and anxiolytic properties. The company believes that
oxidative stress, not amyloid-beta, is the cause of Alzheimer's. ANAVEX
1-41 uses sigma receptors, a unique class of receptor molecules, to guard
against oxidative stress and repair cells compromised by its effects. So
far, through the advanced pre-clinical phase of development, the compound
has performed extremely well in well-recognized animal models of
Alzheimer's disease, underscoring the promise of this alternative approach
to the disease.
ANAVEX SIGMACEPTOR(TM)-C program involves the development of novel and
original drug candidates targeting cancer. The company's lead drug
candidates exhibit high, non-exclusive affinity for sigma receptors with
strong evidence for selective pro-apoptotic, anti-metastatic and low
toxicity properties in various types of solid cancers such as colon,
prostate, breast and lung. ANAVEX 7-1037 has already demonstrated its
ability to significantly delay the growth of cancerous tumors in
patient-derived xenografts during advanced pre-clinical studies.
