Benzoylation of sulfasalazine in aqueous 1,4-dioxane
摘要
The study of the kinetics of the reaction of sulfasalazine with picryl benzoate in aqueous 1,4-dioxane with a water content of 10 wt.% in a temperature range of 298–313 K revealed a low reactivity of sulfasalazine: the rate constants do not exceed k=(1.807±0.090) • 10−3 L mol−1 s−1. According to the results of virtual screening (using the PASS Online program) of the biological activity and toxicity of sulfasalazine and its N-benzoylated product, the reaction product has a reduced probability of insulin inhibition and antagonistic action against p-aminobenzoic acid, as well as nephro-, hepato- and hematotoxicity.
