Summary: Cytoglobin has physiological roles that are not clearly understood, but may include regulation of nitric oxide, oxygen sensing, and protection against oxidative stress. Specific mutations can affect the nitric oxide binding and metabolism activities of cytoglobin, helping to understand its precise role under physiological and pathophysiological conditions.

Summary: This study reports the generation of N2O in a nonheme complex upon addition of NO. A metastable FeNO intermediate was trapped and characterized by low-temperature spectroscopic studies. Thermal decay of the FeNO species was found to result in the evolution of N2O, without the requirement of any exogenous electron or proton sources.

Summary: In this study, the electronic and geometric structural properties of O2-derived aliphatic thiolate-ligated Fe-peroxo, Fe-hydroxo, and Fe(IV) oxo compounds were examined. The results showed that the Fe(IV) oxo compounds are capable of cleaving strong C-H bonds and forming peroxo intermediates. Additionally, the formation processes of several reaction intermediates were discovered through experimental and computational studies.

Summary: The nature of reactive intermediates and the cis-dihydroxylation mechanism of arenes and olefins have been studied extensively in the past few decades. In this study, the reaction between a spectroscopically characterized mononuclear nonheme iron(III)-peroxo complex and olefins and naphthalene derivatives has been investigated. The results show that the nonheme iron(III)-peroxo complex is a nucleophile and reacts with olefins and naphthalenes to yield cis-diol products. This study presents the first example of cis-dihydroxylation of substrates by a nonheme iron(III)-peroxo complex.

Summary: This study evaluated the importance of hydrogen sulfide (NaHS) and nitric oxide (SNP) in the antioxidant systems of rice seedlings under Cr(III) stress. The results showed that NaHS and SNP effectively alleviated the toxic effects of Cr(III) by activating different antioxidants. NaHS had a stronger regulatory effect on non-enzymatic and enzymatic antioxidants compared to SNP.

Summary: In this study, hard X-ray spectroscopic methods were used to investigate the structural features of two photolabile {FeNO}(6) complexes. The presence of a pendant thiol or thioether was found to affect the ability of the complexes to generate HNO. The findings of this study are important for future research on these systems and other challenging redox systems.

Summary: Nitroxyl and nitroxide anions are the reduced forms of nitric oxide and have distinct advantages in pharmacology and therapy. However, the role of nitroxyl in chemical biology is not as extensively studied as nitric oxide. Metal nitrosyl complexes can serve as efficient nitroxyl donors, overcoming the limitations of existing examples.
