Comparative bioequivalence study of different brands of acetyl salicylic acid in human volunteers.

A double blind cross over randomized study was conducted in 7 normal healthy volunteers. Single dose (700 mg) of buffered aspirin or aspirin with calcium carbonate or aspirin with caffeine was administered orally, at least 3 days apart. Blood samples were drawn at different time intervals after administration of drug for estimation of salicylate levels. The values of different pharmacokinetic parameters (AUC0-infinity, Cmax and tmax) did not show any significant difference, suggesting that these three brands of aspirin are biologically equivalent.

An early salicylic acid-, pathogen- and elicitor-inducible tobacco glucosyltransferase: role in compartmentalization of phenolics and H2O2 metabolism.

Treatment of tobacco cell suspension cultures with a fungal elicitor of defense responses resulted in an early accumulation of the phenylpropanoid glucosyltransferase TOGT, along with the rapid synthesis and secretion of scopolin, the glucoside of scopoletin. Elicitor-triggered extracellular accumulation of the aglycone scopoletin and of free caffeic and ferulic acids could only be revealed in the presence of diphenylene iodonium, an inhibitor of extracellular H2O2 production. Our results strongly support a role for TOGT in the elicitor-stimulated production of transportable phenylpropanoid glucosides, followed by the release of free antioxidant phenolics into the extracellular medium and subsequent H2O2 scavenging.
