Piloty’s acid derivative with improved nitroxyl-releasing characteristics
摘要:
Recent studies have shown that nitroxyl (HNO) ((HNO)-H-1/(NO)-N-3 ), which is the one-electron-reduced form of nitric oxide (NO), has unique biological activities, especially in the cardiovascular system, and HNO-releasing agents may have therapeutic potential. Since few HNO donors are available for use under physiological conditions, we synthesized and evaluated a series of Piloty's acid (PA) derivatives and evaluated their HNO-releasing activity under physiological conditions. N-Hydroxy-2-nitrobenzenesulfonamide (17) was the most efficient HNO donor among our synthesized PA derivatives, including the lead compound, 2-bromo-N-hydroxybenzenesulfonamide (2). The high HNO-releasing activity is suggested to be due to electronic and steric effects. Compound 17 may be a useful tool for biological experiments. (C) 2013 Elsevier Ltd. All rights reserved.
The present disclosure provides nitroxyl donating pharmaceutical compositions comprising N-substituted hydroxylamine derivatives. The compositions are highly efficacious in treating cardiovascular diseases (e.g., heart failure), have a suitable toxicological profile, and are sufficiently stable for intravenous or oral administration.

The present disclosure provides compounds having the general structure A or pharmaceutically acceptable salts thereof:
R—X (A)
wherein R is an alkyl or aryl moiety comprising heterocyclic structures; and X is a metal-chelatin group selected from:
This disclosure further provides a focused library of compounds for use in the discovery and design of metallo-enzyme inhibitors. This fragment-based approach provides an assembly of a library of low molecular weight compounds (MW<300 Da) containing a variety of potential metal-chelating groups. The identification of the inhibitory scaffolds among these compounds provides the initial hit fragments that may be optimized for affinity against a particular target using common medicinal chemistry, structure-based or NMR-based approaches.
