Synthesis and Biological Evaluation of Novel 1-Deoxy-1-[6-[((hetero)arylcarbonyl)hydrazino]- 9H-purin-9-yl]-N-ethyl-β-d-ribofuranuronamide Derivatives as Useful Templates for the Development of A2B Adenosine Receptor Agonists
摘要:
The lack of molecules endowed with selective and potent agonistic activity toward the hA(2B) adenosine receptors has limited the studies on this pharmacological target and consequently the evaluation of its therapeutic potential. We report the design and the synthesis of the first potent (EC50 in the nanomolar range) and selective hA(2B) adenosine receptor agonists consisting of 1-deoxy-1-[6-[((hetero)arylcarbonyl)hydrazino]-9H-purin-9-yl]-N-ethyl-beta-D-ribofuranuronamide derivatives. The concurrent effect of 6-substitution of the purine nucleus with a ((hetero)arylcarbonyl)hydrazino function and a 2-chloro substitution has been investigated in such NECA derivatives.
