Preferred Abstract (Original): 

Tethering the N-8-substituents of N-8-substituted styryl xanthine to N-7 has resulted in a series of conformationally constrained styryl xanthine analogs having the general formula 8. These new compounds have also been evaluated in order to investigate if the A2A adenosine receptor would be able to tolerate such a modification.
