Reactions of Hydroxyl Radical with Salicylic Acid Derivatives: A Pulse Radiolysis Study

CHINESE JOURNAL OF CHEMISTRY, Issue 9 2005
Jian-Hua Ma
Abstract Based on pulse radiolysis of aqueous solutions of two salicylic acid derivatives including ethyl salicylate and benzylsalicylate the transient absorption spectra and the rate constants of hydroxyl radical with salicylic acid derivatives were determined for the first time. The results indicated that ethyl salicylate and benzylsalicylate have efficient activities to scavenge hydroxyl radical. [source]

Retention data from reverse-phase high-performance thin-layer chromatography in characterization of some bis-salicylic acid derivatives

BIOMEDICAL CHROMATOGRAPHY, Issue 8 2009
-Sekuli, Tatjana Djakovi
Abstract The chromatographic behaviour of salicylic acid derivatives was investigated using reversed-phase high performance thin-layer chromatography (RP HPTLC) with methanol,water and dioxane,water binary mixtures as mobile phase in order to establish relationships between chromatographic data and selected physico-chemical parameters that are related to ADME (absorption, distribution, metabolism and elimination). Some of the investigated compounds were screened for antioxidant activity. Examination of chromatographic behaviour revealed a linear correlation between RM values and the volume fraction of mobile phase modifier. Obtained RM0 values were correlated with lipophilicity, solubility, human intestinal absorption, plasma-protein binding, and blood,brain barrier data. The comparison among chromatographic data obtained by two mobile phase was performed with a statistical technique, principle component analysis. Copyright © 2009 John Wiley & Sons, Ltd. [source]
