Abstract: Phthalazinediones that function as intracellular redox modulators in the redox therapy of certain stressed cells are provided. By buffering aberrant redox states, phthalazinediones enable cellular processes essential for survival and augment medical treatments. The phthalazinediones of the invention can modulate functions related to cell growth, differentiation, activity, or death, to correct aberrations and restore homeostasis, and can serve as adjunctive therapy in treating various disease conditions.

Abstract: The present invention comprises methods of manufacturing a highly purified, pharmaceutical grade phthalazinedione (for example, 5-amino-2,3-dihydrophthalazine-1,4-dione) for administration to a human or animal. The manufacturing methods identify and isolate starting materials (for example, 3-nitrophthalic acid), and prepare intermediate products (for example, 3-nitrophthalhydrazide), which are suitable for the commercial batch process production of highly purified and high-yielding intermediate products and final phthalazinedione products. In an embodiment, a solution of 3-nitrophthalhydrazide and sodium hydroxide in water is prepared and hydrogenated to yield 5-amino-2,3-dihydrophthalazine-1,4-dione.

Abstract: Phthalazine diones that function as intracellular redox modulators and buffers are used to treat stressed cells in various disease states in which the intracellular redox status is impaired. By optimal buffering of aberrant redox states, phthalazine diones enhance the cellular processes essential for survival and augment the conventional or other external therapies necessary for treatment. The phthalazine diones of the invention thus regulate cell growth, differentiation, or death to serve as essential adjunctive therapy for the stressed host in various disease states.

Abstract: Herein is provided a method for identifying extreme stressors which may become causative agents responsible for syndromes characterized by premature progressive cell loss or cell over growth in an individual. A sample of cells obtained from an individual is subjected to stressor in vitro to form a stressed cell sample. At least one stress criteria is measured for the stressed cell sample and the steps are repeated for a plurality of stressors. The measured stress criteria are then compared to norms derived from such measurements on cell samples obtained from third parties and a plurality of extreme stressors to which the sample of cells taken from the individual are unusually sensitive are identified. The procedure can be used to identify an effective bypass agent or needed alteration in lifestyle to prevent or delay clinical signs of disease, and/or to identify an effective bypass agent or needed alteration in lifestyle to better manage or reverse the course of the disease process.
