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 کاملComparison of Prehospital Glucose with or without IV Thiamine
INTRODUCTION Loading of thiamine prior to glucose administration during hypoglycemia to prevent Wernicke's encephalopathy is routine in the prehospital setting. To date no study has looked at the validity of this therapy. METHODS We evaluated a retrospective cohort of 242 patients who received intravenous glucose for hypoglycemia comparing those who received thiamine supplementation versus th...
متن کاملInhibition of Thiamine Pyrophosphate Utilization by Thiamine
The growth of a thiamine pyrophosphate auxotroph of Escherichi coli was inhibited by either thiamine or thiamine monophosphate, and the growth of a thiamine monophosphate auxotroph was inhibited by thiamine. The thiamine pyrophosphate-dependent oxidation of pyruvate was inhibited by thiamine with whole cells of the thiamine pyrophosphate auxotroph but not with cell extracts prepared from the sa...
متن کاملBis(phenylphosphonic) anhydride
The asymmetric unit of the title compound, C(12)H(12)O(5)P(2), contains four independent mol-ecules, generating two dimers via pairs of inter-molecular O-H⋯O hydrogen bonds, forming R(2) (2)(8) rings. The two aryl rings of each mol-ecule form dihedral angles of 108.6 (1), 103.2 (1), 12.5 (2) and 8.1 (2)° in the four mol-ecules.
متن کاملN-Phenylanthranilic anhydride
The complete mol-ecule of the title compound, C(26)H(20)N(2)O(3), is generated by crystallographic twofold symmetry, with the central O atom lying on the rotation axis. The conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. The dihedral angle between the inner and outer aromatic ring planes is 61.12 (5)°.
