alkylamine-substituted perthiocarbamates. Triggered by a base-sensitive, self-immolative moiety, these precursors show efficient RSSH release, and also demonstrate the ability to generate carbonyl sulfide (COS) in the presence of thiols. Using this dually reactive alkylamine-substituted perthiocarbamate platform, the generation of both RSSH and COS is tunable with respect to half-life, pH, and availability

The present invention includes methods for making and isolating N-acetylcysteine amide, intermediates and derivatives thereof comprising: contacting cystine with an alcohol and a chlorinating reagent to form an organic solution containing L-cystine dimethylester dihydrochloride; combining dried or undried L-cystine dimethylester dihydrochloride with a triethylamine, an acetic anhydride, and an acetonitrile to form a di-N-acetylcystine dimethylester; mixing dried di-N-acetylcystine dimethylester with ammonium hydroxide to form a di-N-acetylcystine amide; and separating dried di-N-acetylcystine dimethylester into N-acetylcysteine amide with dithiothreitol, triethylamine and an alcohol.

presumed signaling products of hydrogensulfide (H2S)-mediated thiol (RSH) modification, are additional potential targets of HNO. However, the interaction of HNO with reactive sulfur species beyond thiols remains relatively unexplored. Herein, we present characterization of HNO reactivity with H2S and RSSH. The reaction of H2S with HNO leads to the formation of hydrogen polysulfides and sulfur (S8),
硝基氧(HNO)由于其有希望的药理作用而受到了广泛的关注。HNO活性的生化机制与调节硫醇蛋白有关。近来,一些研究表明,氢硫化物(RSSH)是硫化氢(H 2 S)介导的硫醇(RSH)修饰的推测信号产物,是HNO的其他潜在目标。然而,相对于硫醇,HNO与反应性硫物种之间的相互作用仍未被探索。本文中,我们介绍了HNO与H 2 S和RSSH反应性的表征。H 2 S与HNO的反应导致形成多硫化氢和硫(S 8),表明其在亚砜硫稳态中的潜在作用。此外,我们显示氢过硫化物比其巯基对应物更有效地捕获HNO。通过观察到各种二烷基多硫化物(RSS n SR)和其他含氮二烷基多硫化物(RSS–NH–S n R)的产生,对HNO与RSSH在不同化学计量比下的反应进行了检查。我们没有观察到亚硫磺酰胺(RS–S(O)–NH 2)形成的证据,这是与HNO与硫醇的已知反应性类似的预期途径。
