Benzoyl coenzyme A (benzoyl-CoA) reductase is a central enzyme in the anaerobic degradation of organic carbon, which utilizes a common intermediate (benzoyl-CoA) in the metabolism of many aromatic compounds. The diversity of benzoyl-CoA reductase genes in denitrifying bacterial isolates capable of degrading aromatic compounds and in river and estuarine sediment samples from the Arthur Kill in N...

Well-established label in biomolecules analysis, fluorescein isothiocyanate is commercially available its two different isomers with equal fluorescence sensitivity, differing meta- vs. para-isothiocyanate position. It was found this study that the stability of depends on polarity solvents and pyridine (stabiliser) presence. The lowest has water solvent. In acidic solution, their quinoid (acid) ...

A structure-activity relationship study was carried out to identify structural features in arylalkyl and alkyl isothiocyanates that are associated with the inhibitory potency of these compounds against lung tumorigenesis induced in A/J mice by the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). These features include the alkyl chain length, phenyl substitution...

A one-pot method for the preparation of benzoyl metronidazole was achieved by using N,N'-carbonyldiimidazole as a coupling reagent. Moreover, it was found that the byproduct imidazole as the catalyst promoted the reaction. In addition, the β-cyclodextrin solubilization of benzoyl metronidazole was investigated by phase-solubility method. The phase-solubility studies indicated that the solubilit...

Acne vulgaris is a common and chronic skin disease, and is a frequent source of morbidity for affected patients. Treatment of acne vulgaris is often difficult due to the multifactorial nature of this disease. Combination therapy, such as that containing clindamycin and benzoyl peroxide, has become the standard of care. Several fixed formulations of clindamycin 1% and benzoyl peroxide of varying...

a facile one step synthesis of anilino alky1-n-substituted phthalimide i is reported. the following compounds belonging to this series were made: 1. (anilino-n-ethyl) phthalimide 8 2. (3,4, 5-trimethoxy anilino-n-ethyl) phthalimide 6 3. (3,4, 5-trimethoxy anilino-n-propyl) phthalimide 7 4. n-(ethyl phthalirnido-p-amino benzoyl) glutamic acid diethyl ester 10 5. n-(propyl phthalimido-p-amino ben...

Sir, Benzoyl peroxide (BP) is an e¡ective and frequently used topical medication for the treatment of acne vulgaris. It is a strong, broad spectrum bactericidal agent that signi¢cantly decreases the number of Propionibacterium acnes in both the follicle and on surface skin (1). A common side e¡ect after usage is irritation of the skin, usually manifested as a stinging or burning, and sometimes ...

Substituted azafluorenones were synthesized from different dihalogeno diaryl ketones under palladium catalysis by combining either Suzuki or Heck coupling with direct cyclizing arylation. Conditions were identified to allow both auto-tandem processes to proceed successfully from 3-(bromobenzoyl)- or 3-benzoyl-4-bromo-2-chloropyridines, as well as 4-benzoyl-2,3- and 4-benzoyl-2,5-dichloropyridines.
