  The invention relates to N-hydroxylsulfonamide derivatives for formula (I), (II) or (III), in which the variables are as defined in the claims, that donate nitroxyl (HNO) under physiological conditions and are useful in treating and/or preventing the onset and/or development of diseases or conditions that are responsive to nitroxyl therapy, including heart failure and ischemia/reperfusion injury. N-hydroxylsulfonamide derivatives release HNO at a controlled rate under physiological conditions, and the rate of HNO release is modulated by varying the nature and location of the functional groups on the N-hydroxylsulfonamide derivatives.

  该发明涉及公式（I）、（II）或（III）的N-羟基磺酰胺衍生物，其中变量如索权中定义的那样，在生理条件下释放亚硝基（HNO），并且在治疗和/或预防对亚硝基疗法敏感的疾病或病症的发生和/或发展中具有用处，包括心力衰竭和缺血/再灌注损伤。N-羟基磺酰胺衍生物在生理条件下以受控速率释放HNO，HNO释放速率通过改变N-羟基磺酰胺衍生物上的功能基团的性质和位置来调节。
