title: Synthesis and some biological properties of substituted xanthone-2-carboxylic acids.
abstract: Xanthone-2-carboxylic acids 4a-4k were synthesized as potential antiphlogistic compounds, and compounds 4a-4c and 4f-4i were tested for anti-inflammatory and analgesic properties. In the carrageenin paw edema the most potent of the series acid 4b displayed the activity which was approx one third of that of ketoprofen.
