The present invention relates to a novel process for the synthesis of mono- and bis-nitrosylated propanediols, as well as novel compositions and pharmaceutical formulations comprising said compounds. The process proceeds by reacting a corresponding propanediol that is not nitrosylated with a source of nitrite, optionally in the presence of a suitable acid. Wherein, when the source of nitrite is an organic nitrite, reacting step is performed in a suitable organic solvent, and when the source of nitrite is an inorganic nitrite, the reacting step is performed in a bi-phasic solvent mixture comprising an aqueous phase and a non-aqueous phase. The invention also relates to methods of treating a condition wherein administration of nitric oxide (NO) has a beneficial effect by administering said compounds, compositions or formulations.
本发明涉及一种新型的合成单烷基和双烷基硝基丙二醇的方法,以及包含这些化合物的新型组合物和制药配方。该方法通过将未硝化的相应丙二醇与亚硝酸盐源反应,可选地在适当的酸的存在下进行。其中,当亚硝酸盐源为有机亚硝酸盐时,反应步骤在适当的有机溶剂中进行;当亚硝酸盐源为无机亚硝酸盐时,反应步骤在包含水相和非水相的两相溶剂混合物中进行。本发明还涉及通过给予这些化合物、组合物或配方治疗一种情况的方法,其中通过给予一氧化氮(NO)具有益处的作用。
