Although a number of plant natural products are derived from benzoic acid, the biosynthesis of this structurally simple precursor is poorly understood. Hypericum calycinum cell cultures accumulate a benzoic acid-derived xanthone phytoalexin, hyperxanthone E, in response to elicitor treatment. Using a subtracted complementary DNA (cDNA) library and sequence information about conserved coenzyme A...

The problem of the origin of the glycine available for hippuric acid synthesis after the administration of benzoic acid or its salts has been studied by many investigators with varying results. It should be borne in mind, in this connection, that all species of animals do not react similarly in response to the ingestion of benzoic acid. Thus the organisms of man (l), the rabbit (2), the goat (3...

The mol-ecular structure of the title compound, C20H18N2O5S·C3H7NO, represents an essentially planar 5-benzyl-idene-thia-zolidine moiety (r.m.s. deviation from planarity without ring substituents = 0.095 Å) to which the 4-amino-benzoic acid fragment is inclined at 76.23 (1)°. In the crystal, the benzoic acid mol-ecules are arranged in layers parallel to [001] which are built up from inversion d...

cr(iii), co(ii), ni(ii), cu(ii) and zn(ii) salts of 2-(4-nitrophenylaminocarbonyl)benzoic acid were characterized by physical, analytical and spectroscopic studies and checked for their  in-vitro antimicrobial activity against three bacterial strains, mycobacterium smegmatis (gram +ve), escherichia coli (gram -ve), pseudomonas aeuroginosa (gram -ve) and three fungal strains, nigrospora oryzae, ...

The mechanisms by which the weak acid preservative benzoic acid inhibits the growth of Saccharomyces cerevisiae have been investigated. A reduction in the pyruvate kinase level, which decreases glycolytic flux, did not increase the sensitivity of yeast to benzoic acid. However, a decrease in 6-phosphofructo-1-kinase (PF1K), which does not affect glycolytic flux, did increase sensitivity to benz...

The roles of benzoic acid and water on the Michael reaction of pentanal and nitrostyrene catalyzed by diarylprolinol silyl ether are revealed by density functional theory calculations. The calculations demonstrate that the benzoic acid is ready to attack the catalysts and form a hydrogen bond between the hydrogen atom of the COOH of benzoic acid and one of the N atoms of the catalyst. The compl...
