硫化氢(H2S)在许多(病理)生理过程中表现出有前途的保护作用,最近的报道证明了在不同的生物模型中使用合成H2S供体。在此,我们报告了PeroxyTCM的设计和评价,其包括第一类活性氧(ROS)触发的H2S供体。这些供体在水溶液中是稳定的,并且不释放H2S,直到被ROS触发,例如过氧化氢(H2 O2),超氧化物(O2−)和过氧亚硝酸盐(ONOO−)。我们在活细胞中证明了ROS触发的H2S捐赠,并且还证明了PeroxyTCM-1提供了对H2 O2诱导的氧化损伤的保护,这表明PeroxyTCM和类似支架在H2S相关治疗中的潜在未来应用。H2S是一种重要的生物分子,H2S供体是有价值的研究和药理学工具。我们报告的设计和细胞评估的H2S供体,触发释放H2S暴露于活性氧(ROS)。
Hydrogen sulfide (H2S) exhibits promising protective effects in many (patho)physiological processes, as evidenced by recent reports using synthetic H2S donors in different biological models. Herein, we report the design and evaluation of PeroxyTCM, which comprises the first class of reactive oxygen species (ROS)-triggered H2S donors. These donors are stable in aqueous solution and do not release H2S until triggered by ROS, such as hydrogen peroxide (H2O2), superoxide (O2−), and peroxynitrite (ONOO−). We demonstrate ROS-triggered H2S donation in live cells and also demonstrate that PeroxyTCM-1 provides protection against H2O2-induced oxidative damage, suggesting potential future applications of PeroxyTCM and similar scaffolds in H2S-related therapies. H2S is an important biomolecule and H2S donors are valuable research and pharmacological tools. We report the design and cellular evaluation of an H2S donor that is triggered to release H2S by exposure to reactive oxygen species (ROS).
