    • 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. In one embodiment, the C-nitroso compound is obtained by nitrosylation of a conventional drug or such drug modified to modify the carbon acid pKa thereof When such drug is a nonsteroidal anti-inflammatory drug, the resulting C-nitroso compound functions as a COX-1 and COX-2 inhibitor without the deleterious effects associated with COX-1 inhibition but with the advantageous effects associated with COX-1 and COX-2 inhibition. One such C-nitroso compound is a nitrosoketoibuprofen. A specific example of this kind of compound is isolated as dimeric 2-[4′-(α-nitroso)isobutyrylphenyl]propionic acid. In another case, the C-nitroso compound contains the moiety where X is S, O or NR. One embodiment is directed to COX-2 inhibitors where a tertiary carbon atom and/or an oxygen atom and/or a sulfur atom is nitrosylated.
    • 单体基团的分子量范围为约225至约1,000(约225至约600)的C-亚硝基化合物,其中亚硝基连接到叔碳上,其通过碳的亚硝基化获得 pKa小于约25的酸可用作NO供体。 当化合物从pKa小于约10的碳酸获得时,当以微摩尔浓度使用时,其提供血管松弛效果,并且该活性由以纳摩尔浓度获得的谷胱甘肽加强。 当化合物由pKa为约15至约20的碳酸获得时,在没有谷胱甘肽的纳摩尔浓度下获得血管松弛效果。 该化合物优选是水溶性的并且优选地含有作为酮基的一部分的亚硝基化碳的碳α。 在一个实施方案中,C-亚硝基化合物通过常规药物的亚硝基化或经修饰以改变其碳酸pKα的药物而获得。当这种药物是非甾体抗炎药物时,所得的C-亚硝基化合物起COX- 1和COX-2抑制剂,没有与COX-1抑制相关的有害作用,但具有与COX-1和COX-2抑制相关的有利效果。 一种这样的C-亚硝基化合物是亚硝基基布洛芬。 这种化合物的具体实例被分离为二聚2- [4' - (α-亚硝基)异丁酰苯基]丙酸。 在另一种情况下,C-亚硝基化合物包含其中X是S,O或NR的部分。 一个实施方案涉及其中叔碳原子和/或氧原子和/或硫原子被亚硝酰化的COX-2抑制剂。

    • 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.
