Studies in Animals Demonstrate AMPAKINE Molecules Reverse Memory Loss in Huntington’s Disease

Business Wire
Cortex Pharmaceuticals, Inc. (NYSE Alternext US (COR)) announced
that preclinical studies from the laboratory of Professor Gary
Lynch at the University of California Irvine, one of the scientific
founders of the company, demonstrated that AMPAKINE� molecules show
promise in the treatment of memory loss in Huntington�s disease.
The studies were performed in mice harboring the genetic mutation
found in humans that is responsible for Huntington�s disease. The
related results demonstrated that treating mice with CX929, a High
Impact AMPAKINE, produced dramatic increases in the brain�s
chemical processes for creating and storing memories. These studies
were published in the early online version of the prestigious,
peer-reviewed journal, Proceedings of the National Academy of
Sciences (PNAS).
Huntington's disease is a progressive, hereditary brain disease
that affects men and women alike, and affects 30,000 patients in
the U.S., with another 150,000 at risk. It is caused by the death
of specific brain cells and is characterized by the gradual
development of involuntary muscle movements, progressive
deterioration of cognitive processes and memory (dementia), and
severe behavioral disturbances. The memory impairments include
altered organization, generally slowed processing of information by
the brain, and executive function � that is, the ability to plan,
abstract thinking and multi-tasking.
�One protein in particular, brain-derived neurotrophic factor
(BDNF), is reduced in Huntington�s disease. We know that BDNF plays
an essential role in maintaining the health of the brain,�
commented Professor Lynch. �And our studies now demonstrate that we
can restore levels of BDNF by treating mice with an AMPAKINE, which
reverses the memory impairments.�
Mark A. Varney, President and CEO stated that, �Professor
Lynch�s studies in mice support the rationale for Cortex to develop
AMPAKINE molecules to address the memory deficits in patients
suffering from Huntington�s disease. Also, the link to BDNF may
play an important role in other neurodegenerative diseases such, as
Alzheimer�s Disease.�

Cortex Pharmaceuticals, Inc.
Cortex, located in Irvine, California, is a neuroscience company
focused on novel drug therapies for treating psychiatric disorders,
neurological diseases and brain-mediated breathing disorders.
Cortex is pioneering a class of proprietary pharmaceuticals called
AMPAKINE compounds, which act to increase the strength of signals
at connections between brain cells. The loss of these connections
is thought to be responsible for memory and behavior problems in
Alzheimer�s and Huntington�s disease. Many psychiatric diseases,
including schizophrenia, occur as a result of imbalances in the
brain�s neurotransmitter system. These imbalances may be improved
by using the AMPAKINE technology. For additional information

ineffective for any or all of their proposed indications; that
patents may not issue from the Company�s patent applications; that
competitors may challenge or design around the Company�s patents or
develop competing technologies; that the Company may have
insufficient resources to undertake proposed clinical studies; and
that preclinical or clinical studies may at any point be suspended
or take substantially longer than anticipated to complete. As
discussed in the Company�s Securities and Exchange Commission
filings, the Company�s proposed products will require additional
research, lengthy and costly preclinical and clinical testing and
regulatory approval. AMPAKINE compounds are investigational drugs
and have not been approved for the treatment of any disease.
