We report the facile preparation of a family of S-aroylthiooxime (SATO) H2S donors, which are synthesized via a click reaction analogous to oxime formation between S-aroylthiohydroxylamines (SATHAs) and aldehydes or ketones. Analysis of cysteine-triggered H2S release revealed structure-dependent release kinetics with half-lives from 8–82 min by substitution of the SATHA ring. The pseudo-first-order
我们报告的家庭-S-芳香酰硫肟(SATO)H 2 S供体的简便制备,通过类似于在S-芳香酰硫羟胺(SATHAs)与醛或酮之间肟形成的点击反应合成。半胱氨酸触发的H 2 S释放分析表明,通过取代SATHA环,结构依赖的释放动力学具有8-82分钟的半衰期。取代的SATO的拟一阶速率常数符合标准线性自由能关系(ρ= 1.05),表明对电子效应具有显着的敏感性。
