Structure–affinity relationships of the affinity of 2-pyrazolyl adenosine analogues for the adenosine A2A receptor
摘要:
The structure-affinity relationships of two novel 2-substituted adenosine series containing a substituted pyrazole attached at the N-1 or C-4 position for the adenosine (ADO) A(2A) receptor are described. Compounds in the 2-(N-1-pyrazolyl) adenosine series IV provided the highest affinity for the ADO A(2A) receptor as compared to the 2-(C-4-pyrazolyl) series V. The main structural differences between the two series point to the N-1 nitrogen of series IV imparting more favorable binding interactions with the receptor than those of series V.
