In the present work, we report the unexpected formation of isomeric 3-benzoyl-2-phenylbenzo[b]furans using triphenylphosphonium salt and benzoyl chlorides under Wittig conditions.

ABSTRACT The novel benzoyl coenzyme A (benzoyl-CoA) biosynthesis pathway in “Streptomyces maritimus” was investigated through a series of target-directed mutations. Genes involved in benzoyl-CoA formation were disrupted through single-crossover homologous recombination, and the resulting mutants were analyzed for their ability to biosynthesize the benzoyl-CoA-primed polyketide antibiotic enterocin. Inactivation of the unique phenylalanine ammonia-lyase-encoding gene encP was previously shown to be absolutely required for benzoyl-CoA formation in “S. maritimus”. The fatty acid β-oxidation-relat

Abstract:

Among dermatological diseases demodicosis and acne occupy a very important place. The incidence of demodicosis is more than 5% and ranks seventh in frequency among dermatological diseases. It is known that demodicosis can turn into acne. Treatment of demodicosis and acne does not lose its relevance. This medical problem can be solved through the development of the composition and technology of a soft drug of complex action with the content of active substances used to treat these diseases. Since in dermatology for external use the optimal soft medicines is a cream (taking into account th

Abstract:

The urinary metabolites of benzoic acid have been studied in seven marsupial species and the rat. Benzoic acid was excreted mainly as the glycine conjugate, hippuric acid, with smaller, though variable, amounts as benzoyl glucuronide. Thus the overall pattern of metabolism was similar to that found in most other mammals. All species formed significant amounts of a recently discovered metabolite of benzoic acid, 0-hydroxyphenylpropionic acid, suggesting that the metabolic pathway for its formation, involving the addition of a two-carbon fragment, may occur generally in other species.
