2-styrylchromones as novel inhibitors of xanthine oxidase. A structure-activity study.

abstract：:Adenosine receptors have been considered as potential targets for drug development, but one of the main obstacles to this goal is to selectively inhibit one receptor subtype over the others. This subject is particularly crucial for adenosine A2b receptor antagonists (AdoRA2B). The structure–activity relationships of x...
