  • Patent number: 7049308
    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 20, vascular relaxing effect is obtained at nanomolar concentrations without glutathione. In another embodiment, a biocompatible polymer incorporates a C-nitroso moiety.

  • Patent number: 7030238
    Abstract: A C-nitroso compound having a molecular weight ranging from about 225 to about 1,000 (from about 225 to about 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 glutathione. The compound is preferably water-soluble and preferably contains a carbon alpha to the nitrosylated carbon which is part of a ketone group.

  • Patent number: 6945247
    Abstract: Treatment of pulmonary disorders associated with hypoxemia and/or smooth muscle constriction and/or inflammation comprises administering into the lungs as a gas 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.
