BACKGROUND The efficacy and safety of intra-venous (i.v.) sodium benzoate for treating acute episodes of hyperammonemia in urea cycle enzyme disorders (UCD) is well known. However, published data do not provide a clear picture of the benefits and risks of this drug. We report a retrospective multicentre study on the use of i.v. sodium benzoate in patients treated for UCD between 2000 and 2010 i...
In the title mol-ecule, C(22)H(15)NO(3), the configuration about the ethyl-enic double bond is Z configuration and it is approximately coplanar with the adjacent phenyl ring and benzoxazole ring system as indicated by the C(H)=C(O)-C(phen-yl)-C(phen-yl) and O(benzoxazole)-C-C(H)=C(O) torsion angles of 179.88 (15) and 5.7 (2)°, respectively. The dihedral angle between the essentially planar (r.m...
The reaction of lead acetate, benzoic acid and 1,10-phenanthroline (phen) in aqueous solution yielded the title complex, [Pb(C(7)H(5)O(2))(2)(C(12)H(8)N(2))]·C(7)H(6)O(2). In the crystal, the Pb(II) ion is hexa-coordinated by two N atoms from one 1,10-phenanthroline ligand and four O atoms from two chelate benzoate anions. If the second benzoate ligand is treated as one coordination site, the o...
The structure of the title compound (23DMPBA), C(15)H(14)O(2), resembles those of phenyl benzoate (PBA), 3-methyl-phenyl benzoate (3MePBA), 2,6-dichloro-phenyl benzoate (26DC-PBA) and other aryl benzoates, with similar bond parameters. The dihedral angle between the benzene and benzoyl rings in 23DMPBA is 87.36 (6)°, compared with values of 55.7° in PBA, 79.61 (6)° in 3MePBA and 75.75 (10)° in ...
Pseudomonas mendocina P2d grew in sodium benzoate at as high as 1% concentration and formed a quinonoid compound, identified as ortho-benzoquinone, that rendered the medium orange to wine-red in colour. The quinone was not metabilised further by the organism. Sodium benzoate was converted to catechol, which was a central metabolite forming ortho-benzoquinone and 2- hydroxymuconic semialdehyde (...
The polarographic wave observed for acetonitrile solutions of benzoic acid is due to reduction of the acid proton: the apparent diffusion current constant for the wave increases with concentration of benzoic acid as expected for the reduction of the acidic proton of a slightly dissociated acid. No wave was observed for ethyl benzoate. The situation in respect to the electrochemical reduction of...
In the title compound, C(16)H(10)ClF(3)O(3), the two benzene rings are slightly twisted from each other, with a dihedral angle of 15.50 (8)° between the planes. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a layer parallel to the bc plane.
