Oxidation Product of Thiamine Anhydride and the Metabolite of Thiamine Anhydride in Rats.
As shown in the previous paper, a metabolite of thiamine anhydride (TA) (I) was isolated as crystals melting at 172-173•‹ from the urine when TA was given parenterally to rats and it was assumed to be thiamine anhydride sulfoxide (TAO) (II) from its analytical data. It is known, however, that TA can be oxidized to TA sulfone (III) besides its sulfoxide by hydrogen peroxide according to the con ...
متن کاملConvergence of Biological Nitration and Nitrosation via Symmetrical Nitrous Anhydride
The current perspective holds that the generation of secondary signaling mediators from nitrite (NO2(-)) requires acidification to nitrous acid (HNO2) or metal catalysis. Herein, the use of stable isotope-labeled NO2(-) and LC-MS/MS analysis of products reveals that NO2(-) also participates in fatty acid nitration and thiol S-nitrosation at neutral pH. These reactions occur in the absence of me...
متن کاملUranyle Complexes: synthesis, evaluation of biological activity
In this research, some of the inorganic complexes of uranyl with N- donor ligandswere synthesized. Complexes were characteriezed by FT-IR and UV spectra, ¹HNMR,¹³CNMR and some physical properties. The uranyl unit (UO2) is composed of a center ofuranium atom with the charge (+6) and two oxygen atom by forming two U=O double bonds.The structure is linear (O=U=O, 180) and usually stable. So other ...
متن کاملEffect of Amino Acid Substitutions on Biological Activity of Antimicrobial Peptide: Design, Recombinant Production, and Biological Activity
Recently, antimicrobial peptides have been introduced as potent antibiotics with a wide rangeof antimicrobial activities. They have also exhibited other biological activities, including antiinflammatory,growth stimulating, and anti-cancer activities. In this study, an analog of MagaininII was designed and produced as a recombinant fusion protein. The designed sequence containe...
