Abstract

Since adenosine A3 receptor has been cloned from rat brain. a number of compounds have been synthesized and evaluated for the binding affinity to this receptor. Among these. 2-chloro-N6-(3-iodobenzyl)-adenosine-5'-methylcarboxamide (2-CI-IB-MECA) has been found to be one of the most selective agonists (Ki = 1.0 nM) for rat adenosine A3 receptor. On the basis of the high binding affinity of 2-CI-IB-MECA to adenosine A3 receptor. it was interesting to find out whether 2'-hydroxyl group of 2-CI-IB-MECA is essential for the binding affnity to the receptor.
