In DN-DISC1 mice, a mouse model for major mental illnesses, the model that expresses
pathological phenotypes relevant to
schizophrenia,
mood disorders, and
addiction simultaneously, the inventors of the present invention found pronounced levels of
oxidative stress in the
prefrontal cortex, but not in the
striatum. These mice also displayed greater amounts of GAPDH-Siah1 binding, a
protein-
protein interaction that is activated under
exposure to
oxidative stress. The present inventors investigated the role of
oxidative stress in other organ systems. As detailed herein, the inventors found that GAPDH-Siah1 binding was increased in mouse models of cardiac failure. It was also found, that certain novel analogs of deprenyl, significantly inhibited GAPDH-Siah1 binding in cardiac tissue. Thus, with experimental data provided herein, it is clear that this GAPDH-Siah1 binding
cascade is a crucial mechanism involved in major
mental illness, such as
schizophrenia,
mood disorders, and
addiction, as well as in stress-associated diseases involving other organs where GAPDH is expressed.The present invention provides compounds and composition comprising analogs of deprenyl and their use in the inhibition of nuclear GAPDH-Siah1 binding and the activation of p300 and MEF2. Also provided herein are methods of prevention and treatment of
stress induced disorders of the body, including, for example, major
mental illness, such as
schizophrenia,
mood disorders, and
addiction, as well as in stress-associated diseases involving other organs, such as
cardiac hypertrophy,
in vivo, comprising administering to a
mammal a therapeutically effective amount of analogs of deprenyl.
