Hemeproteins as targets for sulfide species
(Mary Ann Liebert, 2020-01-02)
The binding of sulfide to ferric hemeproteins has been described in more than 40 systems, including native proteins, mutants, and model systems. Mechanisms of sulfide binding to ferric hemeproteins have been examined by a ...
Scavenging of Hydrogen Peroxide by Allyl Methyl Sulfide and Diallyl Sulfide, Two Garlic Active Compounds: A Theoretical Study
(Wiley Blackwell Publishing, Inc, 2020-03)
We study potential scavenging of hydrogen peroxide by Allyl Methyl Sulfide and Diallyl Sulfide, two garlic components. The antioxidant properties of garlic are attributed to organosulfide compounds, which react with reactive ...
Synthesis of (diphenylphosphinoyl)methyl vinyl sulfides, symmetric and asymmetric divinyl sulfides from bis[(diphenylphosphinoyl)methyl] sulfide
(Georg Thieme Verlag Kg, 2011-04)
Convenient Horner-Wittig-based synthetic approaches to the preparation of (diphenylphosphinoyl)methyl vinyl sulfides as well as symmetrically and unsymmetrically substituted divinyl sulfides, are described. The syntheses ...
Product distribution study of the Cl-atom initiated oxidation of ethyl methyl sulfide and diethyl sulfide
(Pergamon-Elsevier Science Ltd, 2013-12)
The products formed in the gas-phase reactions of Cl atoms with (CH3CH2)2S and CH3CH2SCH3 have been investigated in a large volume reactor in NOx-free air at atmospheric pressure and (298±2) K using long path "in situ" ...
Wittig–Horner mediated synthesis of 4-vinyl sulfide derivatives of pyrazoles
(Pergamon-Elsevier Science Ltd, 2016-06)
The synthesis of a series of 4-vinyl sulfide derivatives of 1,3-diarylpyrazoles, including their corresponding sulfoxides and sulfones, is reported. Access to the target vinyl sulfides was stereoselectively achieved, in ...
Sulfide binding properties of truncated hemoglobins
(American Chemical Society, 2010-03)
The truncated hemoglobins from Bacillus subtilis (Bs-trHb) and Thermobifida fusca (Tf-trHb) have been shown to form high-affinity complexes with hydrogen sulfide in their ferric state. The recombinant proteins, as extracted, ...
Active potassium niobates and titanoniobates as catalysts for organic sulfide remediation
(Elsevier Science, 2016-02)
Pure (KNbO3) and titanium-substituted (KTi0.1Nb0.9O3 and KTi0.2Nb0.8O3) potassium niobates with perovskite crystalline structures were prepared, characterized and tested as catalysts in the selective oxidation of ...
Hydrogen Sulfide Regulates Inward-Rectifying K+ Channels in Conjunction with Stomatal Closure
(American Society of Plant Biologist, 2015-05)
Hydrogen sulfide (H2S) is the third biological gasotransmitter, and in animals, it affects many physiological processes by modulating ion channels. H2S has been reported to protect plants from oxidative stress in diverse ...
Al-pillared montmorillonite as a support for catalysts based on ruthenium sulfide in HDS reactions
(Elsevier Science, 2012-06-30)
Sulfided ruthenium supported catalysts based on an Al pillared Montmorillonite, with different Al contents, have been prepared and characterized by XRD, SBET, TEM, XPS, and tested in the hydrodesulfurization (HDS) of ...
Interaction between hydrogen sulfide and hormones in plant physiological responses
(Springer, 2019-01)
The gasotransmitter, hydrogen sulfide (H 2 S) is involved in plant growth and development, and stress responses. Plant hormones influence the levels of endogenous H 2 S and H 2 S may affect the biosynthesis, transport, and ...
