CGS-15943 is a drug which acts as a potent and reasonably selective antagonist for the adenosine receptors A₁ and A_2A, having a K_i of 3.3nM at A_2A and 21nM at A₁. It was one of the first adenosine receptor antagonists discovered that is not a xanthine derivative, instead being a triazoloquinazoline. Consequently, CGS-15943 has the advantage over most xanthine derivatives that it is not a phosphodiesterase inhibitor, and so has more a specific pharmacological effects profile. It produces similar effects to caffeine in animal studies, though with higher potency.
