Corynebacterium cyclohexanicum n. sp.: a cyclohexanecarboxylic acid utilizing bacterium

Canadian Journal of Microbiology, 1973
A cyclohexanecarboxylic acid utilizing bacterium, strain MU, has been isolated from soil and its taxonomic and physiological nature studied. The organism requires biotin or an unidentified factor present in yeast extract for growth, and can use one of various acids, alcohols, and carbohydrates as the sole carbon source.As the organism is a non-motile ...

The aromatization of cyclohexanecarboxylic acid to hippuric acid: substrate specificity and species differences

Molecular and Cellular Biochemistry, 1985
The ability to convert cyclohexanecarboxylic acid to hippuric acid has been studied in liver from guinea pigs, rabbits, rats and mice using a gas chromatographic - mass spectrometric method employing selected ion monitoring. Guinea pig liver showed the highest activity, giving values double of those found in rabbit liver and five times those in rat ...

Biosynthesis of phoslactomycins: cyclohexanecarboxylic acid as the starter unit

Tetrahedron, 2003
Abstract Phoslactomycins (PLMs) A–F, produced by actinomycetes are polyketide-type antibiotics derived from a hydroxycyclohexanecarboxylic acid or a cyclohexanecarboxylic acid starter unit. Feeding experiments with [2-13C]shikimic acid indicated that the C-18 carbon of PLMs comes from C-5 of shikimate.

Autoxidation of cyclohexanecarboxylic Acid‐l‐¹⁴C

Recueil des Travaux Chimiques des Pays-Bas, 1964
AbstractOxidation of cyclohexanecarboxylic acid‐1‐14C by molecular oxygen at 205°C in the presence of cupric salt of cyclohexanecarboxylic acid and magnesium oxide yielded nearly equal amounts of cyclohexanone and cyclohexene. When cupric salt and magnesium oxide were omitted, only cyclohexanone was obtained. In both cases the label distribution in the

Kinetics and mechanism of coupled synthesis of cyclohexanecarboxylic acid

Russian Journal of Physical Chemistry A, 2015
The effect of the nature of the anion in a palladium salt on a coupled process involving the oxidation of CO and hydrocarboxylation of cyclohexene in the PdX2-CuBr2-THF-H2O system was studied. The kinetics was investigated under the steady-state conditions.

Conformation and reactivity. Part VI. Kinetics of the acid-catalysed esterification in methanol of the trans-decalincarboxylic acids, of the 4-t-butyl- or 2-methyl-cyclohexanecarboxylic acids, of certain trans-4-substituted cyclohexanecarboxylic acids, and of cyclohexanecarboxylic acid

Journal of the Chemical Society B: Physical Organic, 1967
The rates of acid-catalysed esterification in methanol at 30° of the trans-decalincarboxylic acids, of cis- and trans-4-t-butylcyclohexanecarboxylic acid, of cis- and trans-2-methylcyclohexanecarboxylic acid, of trans-4-X-cyclohexanecarboxylic acids (X = OH, CO2Et, CO2Me, Br, or CN), and of cyclohexanecarboxylic acid have been measured.

Use of caproic and cyclohexanecarboxylic acids for determining benzoic and sorbic acids

Pharmaceutical Chemistry Journal, 2013
The possibility of using caproic and cyclohexanecarboxylic acids for determining sorbic and benzoic acids, respectively, was studied. The presence of double bonds in sorbic and benzoic acids decreased significantly their retention times compared with those of their saturated analogs (caproic and cyclohexanecarboxylic acids) on chromatography columns ...

Pharmacokinetics and pharmacodynamics of valproate analogs in rats. III. Pharmacokinetics of valproic acid, cyclohexanecarboxylic acid, and 1-methyl-1-cyclohexanecarboxylic acid in the bile-exteriorized rat.

Drug Metabolism and Disposition, 1992
The pharmacokinetics of valproic acid (VPA) and its structural analogs cyclohexanecarboxylic acid (CCA) and 1-methyl-1-cyclohexanecarboxylic acid (MCCA) were examined in bile-exteriorized rats. A 0.52 mmol/kg dose (equivalent to 75 mg/kg VPA) of test compound (N = 4 rats per compound) was administered as an intravenous bolus.

The Metabolism of Cyclohexanecarboxylic Acid in the Isolated Perfused Rat Liver

Xenobiotica, 1977
1. Cyclohexanecarboxylic acid in isolated perfused rat livers was eliminated from the perfusion system by a first-order process. 2. After 6 h, 16% was excreted in bile as cyclohexylcarbonyl beta-D-glucuronide. The remainder was present in the perfusate as unchanged cyclohexanecarboxylic acid (10%), hippuric acid (50%), hexahydrohippuric acid (2%), 3,4 ...
