  Rapid and Selective Nitroxyl (HNO) Trapping by Phosphines: Kinetics and New Aqueous Ligations for HNO Detection and Quantitation

  摘要：

  Recent studies distinguish the biological and pharmacological effects of nitroxyl (HNO) from its oxidized/deprotonated product nitric oxide (center dot NO), but the lack of HNO detection methods limits the understanding its in vivo mechanisms and the identification of endogenous sources. We previously demonstrated that reaction of HNO with triarylphosphines provides aza-ylides and HNO-derived amides, which may serve as stable HNO biomarkers. We now report a kinetic analysis for the trapping of HNO by phosphines, ligations of enzyme-generated HNO, and compatibility studies illustrating the selectivity of phosphines for HNO over other physiologically relevant nitrogen oxides. Quantification of HNO using phosphines is demonstrated using an HPLC-based assay and ligations of phosphine carbamates generate HNO-derived ureas. These results further demonstrate the potential of phosphine probes for reliable biological detection and quantification of HNO.

  The design and synthesis of a photoactivatable HNO donor incorporating the (6-hydroxynaphthalen-2-yl)methyl (6,2-HNM) photocage coupled to the trifluoromethanesulfonamidoxy analogue of the well-established HNO generator Piloty’s acid is described. The photoactive HNO donor stoichiometrically generates HNO (∼98%) at neutral pH conditions, and evidence for concerted C–O and N–S bond cleavage was obtained

  physiological conditions (pH 7.4 and 37 °C), the CD1 HNO donor can readily decompose with a half-life of ∼90 min. The corresponding stoichiometry HNO from the CD1 donor was confirmed using both Vitamin B and phosphine compound traps. In addition to HNO releasing, specifically, the degradation product 2-oxo-2H-chromene-6-sulfinate (CS1) was generated as a fluorescent marker during the decomposition. Therefore

  硝酰基（HNO）是一氧化氮（NO）的单电子还原产物，在临床试验中治疗充血性心力衰竭引起了人们的极大兴趣。在本文中，我们描述了第一个基于香豆素的化合物-羟基-2-氧代-2H-色烯-6-磺酰胺（CD1）作为双功能HNO供体，它可以释放HNO信号分子和荧光报告分子。在生理条件下（pH 7.4 和 37 °C），CD1 HNO 供体很容易分解，半衰期约为 90 分钟。使用维生素 B 和磷化氢化合物陷阱确认了来自 CD1 供体的相应化学计量 HNO。具体来说，除了释放 HNO 之外，在分解过程中还产生了作为荧光标记的降解产物 2-oxo-2H-chromene-6-sulfinate (CS1)。因此，可以通过荧光产生来准确监测 HNO 的释放量。与CD1供体相比，荧光强度增加了约4.9倍。根据生理条件下 CS1 的荧光产生，确定 HNO 释放的检测浓度限为 ∼0.13 μM。此外，CD1供体的生物

  1-(7-Azabenzobicyclo[2.2.1]heptane)diazen-1-ium-1,2-diolate (16) was designed with the expectation that it would act as a dual nitric oxide (NO) and nitroxyl (HNO) donor that is not carcinogenic or genotoxic. Compound 16, with a suitable half-life (17.8 min) in PBS at pH 7, released NO (19%) and HNO (22%) during a 2 h incubation in PBS at pH 7. In addition, compound 16 exhibited a significant in vitro positive inotropic effect, increased the rates of contraction and relaxation, and increased coronary flow rate, but did not induce a chronotropic effect. Furthermore, compound 16 (13.7 mg kg(-1), po dose) provided a significant reduction in the blood pressure of mice up to 3 h post-drug administration. All these data suggest that compound 16 constitutes an attractive 'lead-compound' that could have potential applications to treat cardiovascular disease(s) such as congestive heart failure.
