Cranberry consumption has shown prophylactic effects against urinary tract infections (UTI), although the mechanisms involved are not completely understood. In this paper, cranberry phenolic compounds and their potential microbial-derived metabolites (such as simple phenols and benzoic, phenylacetic and phenylpropionic acids) were tested for their capacity to inhibit the adherence of uropathoge...

Certain Mycobacteriu form adaptive enzymes for the oxidation of benzoic acid (1). The oxidation proceeds through catechol and protocatechuic acid (2) and is thus similar to that in PseudomonasJEuorescens (3). Neither cyclohexanecarboxylic acid nor any substituted benzoic acid is oxidized by these Mycobacteria, but certain of these compounds can induce the organism to form adaptive enzymes for b...

The iron-assisted hydroxylation of benzoic acid to salicylic acid by 1/H2O2 has been achieved in good yield under mild conditions (where is [Fe(II)(BPMEN)(CH3CN)2](ClO4)2 and BPMEN =N,N'-dimethyl-N,N'-bis(2-pyridylmethyl)ethane-1,2-diamine); the product of this reaction is a novel mononuclear iron(III) complex with a chelating salicylate.

A new chromophore, 2-(4-nitrophenyl)-1H-indole (NPI), was synthesized as a potential photolabile protecting group. Caged benzoic acids featuring the NPI chromophore were model compounds. Benzoic acid released in moderate yields (~ 40–60%) upon photolysis of caged without any additional chemical reagents. Interestingly, an aldehyde, 1-(5-(1-formyl-1H-indol-2-yl)-2-nitrophenyl)ethyl benzoate, iso...

For the first time in the present study the effects of vanillin, vanillyl alcohol, vanillic acid, as well as the newly synthesized vanillin derivative, bis-vanillin, were investigated on the oxidation of dopamine hydrochloride by mushroom tyrosinase. Among them, vanillin and bis-vanillin act as activators, while vanillyl alcohol and vanillic acid exhibited inhibitory effects, the IC50 values be...

We used gas chromatography-mass spectrometry to analyze serum specimens from a patient whose metabolic ketoacidosis resulted from sniffing a toluene-containing substance; we also analyzed a sample of the abused substance itself and a serum specimen from a normal subject. The blood samples from the patient showed abnormally high concentrations of acetoacetic, azelaic, benzoic, and 3-hydroxybutyr...

The previous papers of this series (Bray, Thorpe & White, 1951, 1952e; Bray, Humphris, Thorpe, White & Wood, 1952b, c, d) reported a study of the kinetics in vivo of some reactions involving benzoic acid and some of its precursors, certain precursors of phenols and a series of substituted phenols. A mathematical model was worked out which could account for the effect upon metabolic fate of dose...
