Methods of treating chronic inflammatory diseases using carbonyl trapping agents

InactiveUS6444221B1Improved therapeutic propertyImprove propertiesBiocidePeptide/protein ingredientsEtiologyBenzoic acid
These and other objects of this invention are achieved by providing a novel method and compositions for the clinical treatment of chronic inflammatory diseases. This invention involves use of systemically administered compositions which include primary amine derivatives of benzoic acid as carbonyl trapping agents. These primary therapeutic agents act by chemically binding to and sequestering the aldehyde and/or ketone products of lipid peroxidation. Increased levels of lipid peroxidation have been repeatedly demonstrated as a part of the non-enzymatic "inflammatory cascade" process which underlies the secondary etiology of chronic inflammatory diseases. p-Aminobenzoic acid (or PABA) is an example of the primary therapeutic agent of the present invention. PABA has a small molecular weight, is water soluble, has a primary amine group that reacts with carbonyl-containing metabolites under physiological conditions and is tolerated by the body in relatively high dosages and for extended periods. The carbonyl sequestering agents are used in combination with at least one co-agent so as to produce an additional beneficial physiological effect of an anti-inflammatory nature. Such compositions are administered systemically entirely via the oral route. Co-agents of the present invention include anti-oxidants and free radical trapping compounds (e.g., alpha-tocopherol), compounds having indirect anti-oxidant activity (e.g., selenium), vitamins (e.g., pyridoxine HCl), compounds which facilitate kidney drug elimination (e.g., glycine), metabolites at risk of depletion (e.g., pantothenic acid), sulfhydryl containing chemicals (e.g., methionine), compounds which facilitate glutathione activity (e.g., N-acetylcysteine), and non-absorbable polyamine co-agents (e.g., chitosan).

N-acetylcysteine compositions and methods for the treatment and prevention of cysteine/glutathione deficiency in diseases and conditions

Life-threatening hepatotoxicity in the setting of acetaminophen overdose is due to depletion of glutathione (GSH), a vital cysteine-containing tripeptide that protects cells and organs against oxidant injury. Rapid administration of N-acetylcysteine (NAC), which provides the cysteine necessary to replenish the depleted GSH, is the standard of care for preventing injury in acetaminophen overdose. Beneficial effects of NAC treatment have also been demonstrated in respiratory, cardiovascular, endocrine and infectious and other diseases. In fact, over fifty randomized placebo-controlled trials conducted in diverse clinical settings document positive responses to NAC treatment. The present invention relates to cysteine / glutathione (GSH) deficiency as a previously unrecognized clinical entity that can complicate the course of commonly encountered diseases and methods of treatment of this generalized deficiency involving administering N-acetylcysteine (NAC) or a pharmaceutically acceptable salt or derivative to a subject in need thereof and monitoring the subjects appropriate glutathione blood levels as needed.

Method for the preparation of a heat stable oxygen carrier-containing pharmaceutical composition

A highly purified and heat stable cross-linked nonpolymeric tetrameric hemoglobin suitable for use in mammals without causing renal injury and vasoconstriction is provided. A high temperature and short time (HTST) heat processing step is performed to remove undesired dimeric form of hemoglobin, uncross-linked tetrameric hemoglobin, and plasma protein impurities effectively. Addition of N-acetyl cysteine after heat treatment and optionally before heat treatment maintains a low level of met-hemoglobin. The heat stable cross-linked tetrameric hemoglobin can improve and prolong oxygenation in normal and hypoxic tissue. In another aspect, the product is used in the treatment of various types of cancer such as leukemia, colorectal cancer, lung cancer, breast cancer, liver cancer, nasopharyngeal carcinoma and esophageal cancer. Another application is heart preservation in situations where there is a lack of oxygen supply in vivo, such as in heart transplant or oxygen-deprived heart.

Method for the preparation of a high-temperature stable oxygen-carrier-containing pharmaceutical composition and the use thereof

A high temperature-stable and highly purified cross-linked (optionally ≧70% β-β linked) tetrameric hemoglobin with high efficiency of oxygen delivery suitable for use in mammals without causing renal injury and vasoconstriction is provided. The dimeric form of hemoglobin is degenerated and purification processes are performed on red blood cells from whole blood. Controlled hypotonic lysis in an instant cytolysis apparatus prevents lysis of white blood cells. Nucleic acids from white blood cells and phospholipids impurities are not detected. Blocking of reactive sulfhydryl groups by a sulfhydryl reagent is performed in an oxygenated environment. Flowthrough column chromatography removes different plasma protein impurities. N-acetyl cysteine is added to the cross-linked tetrameric hemoglobin to maintain a low level of met-hemoglobin. The stabilized hemoglobin is preserved in an infusion bag with aluminum overwrap to prevent formation of inactive met-hemoglobin from oxygen intrusion. The product finds use in tissue oxygenation and cancer treatment.

The present invention relates to pharmaceutical kits and methods to treat lung inflammation and redox imbalance in human cystic fibrosis patients using pharmaceutical compositions containing N-acetylcysteine (NAC), pharmaceutically acceptable salts of N-acetylcysteine, or N-acetylcysteine derivatives. In phase I studies, treatment with oral NAC at a dose of from about 1800 mg / day to about 3000 mg / day for a period of 4 weeks produced significant positive effects, namely, it decreased absolute numbers of white blood cells and neutrophils in the sputum and produced concomitant decreases in sputum neutrophil elastase specific activity and sputum interleukin-8 levels, suggesting an amelioration of lung inflammation in the patients. These effects were associated with an increased total GSH level in whole blood as well increased staining for reduced GSH in blood neutrophils, both of which reflect an amelioration of the redox imbalance in the patients. In ongoing phase II studies, oral NAC at a dose of about 2700 mg / day administered in double-blind manner for 12 weeks showed excellent safety and significantly decreased white blood cells in sputum as compared to placebo.
