Abstract:
A C-nitroso compound having a molecular weight ranging from 225 to 1,000 (from 225 to 600 for oral administration) on a monomeric basis wherein a nitroso group is attached to a tertiary carbon, which is obtained by nitrosylation of a carbon acid having a pKa less than about 25, is useful as an NO donor. When the compound is obtained from a carbon acid with a pKa less than about 10, it provides vascular relaxing effect when used at micromolar concentrations and this activity is potentiated by glutathione to be obtained at nanomolar concentrations. When the compound is obtained from a carbon acid with a pKa ranging from about 15 to about 20, vascular relaxing effect is obtained at nanomolar concentrations without ghitathione. In another embodiment, a biocompatible polymer incorporates a C-nitroso moiety.
Abstract:
A reactive oxygen generating enzyme inhibitor with NO donor bioactivity, e.g., nitrated allopurinol, e.g., 1,5-bis(3-nitrooxypropyyl)-1,5-dihydro-4H-pyrazolo[3,4-d]pyrimidine-4-one is useful to treat heart failure, stable angina, ischemic disorder, ischemic reperfusion injury, atherosclerosis, sickle cell disease, diabetes, Alzheimer's disease, Parkinson's disease, ALS and asthma and to obtain proper contraction of heart, skeletal and smooth muscle. Where the disorder is heart failure, administration of the enzyme inhibitor mediates amelioration of acute coronary symptoms and/or myocardial infarction.

Abstract:
Treatment of pulmonary disorders associated with hypoxemia and/or smooth muscle constriction and/or inflammation comprises administering into the lungs as a gas a compound with an NO group which does not form NO2/NOx in the presence of oxygen or reactive oxygen species at body temperature. Treatment of cardiac and blood disorders, e.g., angina, myocardial infarction, heart failure, hypertension, sickle cell disease and clotting disorders, comprises administering into the lungs as a gas, a compound which reacts with cysteine in hemoglobin and/or dissolves in blood and has an NO group which is bound in said compound so that it does not form NO2/NOx in the presence of oxygen or reactive oxygen species at body temperature. Exemplary of the compound administered in each case is ethyl nitrite. Treatment of patient in need of improved oxygenation, blood flow of and/or thinning of blood comprises providing in the patient a therapeutic amount of red blood cells loaded with nitrosylated hemoglobin. A method is directed to screening drugs that increase level of nitrosoglutathione in airway lining fluid.

Abstract:
Delivering nitric oxide to a treatment site, such as in the area of an implanted stent, over a period of hours or days is desirable; however, the storage and release of nitric oxide in medically-relevant situations and amounts is a challenge, in part due to the gaseous nature of nitric oxide and its instability in the presence of oxygen. The present invention provides a method of preparing compositions of matter, particularly those comprising nanotubules, containing nitric oxide or gases with nitric oxide-like biological activity, where the gas is non-covalently bound to the composition. These compositions allow for the storage of nitric oxide or a related gas, followed by controlled release of the gas. Compositions disclosed in the present invention include polymers, articles, pills, capsules, and medical devices.
Abstract:
A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.
