Polyhalogenated compounds are often environmentally persistent and toxic to mammals. Microorganisms that metabolize these compounds can detoxify contaminated environments. Different biochemical mechanisms are used to metabolize polyhalogenated compounds, but few naturally occurring bacteria have this capability. A recombinant bacterium was constructed to metabolize polyhalogenated compounds to ...

A systematic study on the influence of functionality on adsorption of benzoate and phthalate at -alumina–water interface was investigated. Kinetics of adsorption of benzoate and phthalate on -alumina surfaces were performed at constant ionic strength, I= 5× 10−4 mol dm−3 and pH 5 at 25, 30 and 40 ◦C. Kinetics results show that the rate of adsorption of phthalate is ≈2 times more than that of be...

In the centrosymmetric binuclear title complex, [Pb(2)(C(7)H(5)O(3))(4)(C(12)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, each Pb atom is eight-coordinated in a PbO(6)N(2) environment by two N atoms from the 1,10-phenanthroline (phen) ligand, five carboxylate O atoms from four 3-hydroxy-benzoate anions and one O atom from the coordinated water mol-ecule in a distorted bicapped trigonal-prismatic geometry. Th...

In the polymeric title compound, [Cu(3)(C(7)H(5)O(2))(6)(C(11)H(9)N(3)O)(2)](n), square-planar-coordinated Cu(II) ions on crystallographic inversion centres are bound by two monodentate benzoate anions. The resulting [Cu(benzoate)](2) fragments are joined to centrosymmetic [Cu(2)(benzoate)(4)] paddlewheel clusters [Cu⋯Cu = 2.6331 (5) Å] by means of bridging N-(pyridin-4-yl)nicotinamide (4-pna) ...

BACKGROUND In an effort to identify alternate recombinant gene expression systems in Pseudomonas fluorescens, we identified genes encoding two native metabolic pathways that were inducible with inexpensive compounds: the anthranilate operon (antABC) and the benzoate operon (benABCD). RESULTS The antABC and benABCD operons were identified by homology to the Acinetobacter sp. anthranilate opero...

Tryptophan is required for T lymphocyte effector functions. Its degradation is one of the mechanisms selected by tumors to resist immune destruction. Two enzymes, tryptophan-2,3-dioxygenase and indoleamine 2,3-dioxygenase 1, control tryptophan degradation through the kynurenine pathway. A third protein, indoleamine 2,3-dioxygenase 2, was identified more recently. All three enzymes were reported...

The crystal structure of the title compound (4CP4MBA), C(14)H(11)ClO(2), resembles those of 3-chloro-phenyl 4-methyl-benzoate (3CP4MBA), 4-methyl-phenyl 4-methyl-benzoate (4MP4MBA), 4-methyl-phenyl 4-chloro-benzoate (4MP4CBA) and other aryl benzoates with similar bond parameters. The dihedral angle between the benzene rings in 4CP4MBA is 63.89 (8)°, compared with 71.75 (7)° in 3CP4MBA, 63.57 (5...

The structure of the title compound (4CP4CBA), C(13)H(8)Cl(2)O(2), resembles those of 4-methyl-phenyl 4-chloro-benzoate (4MP4CBA), 4-chloro-phenyl 4-methyl-benzoate (4CP4MBA) and 4-methyl-phenyl 4-methyl-benzoate (4MP4MBA), with similar bond parameters. The dihedral angle between the two benzene rings in 4CP4CBA is 47.98 (7)°, compared with 51.86 (4)° in 4MP4CBA, 63.89 (8)° in 4CP4MBA and 63.57...

We report the first case of an anaphylactic reaction to Reandron 1000 (depot testosterone undecanoate with a castor oil and benzyl benzoate vehicle). While considered to have a favourable safety profile, serious complications such as oil embolism and anaphylaxis can occur. In our patient, skin testing identified benzyl benzoate to be the trigger, with no reaction to castor oil or testosterone u...
