摘要

The coronary vasoactivity of N-ethyl-l'-deoxy-l'-(6-amino-SH-purin-9-yl)-~-~-ribofuran~ on~ ide (NECA, 1) is over 2 orders of magnitude greater than that of adenosine, and the vasoactivity of certain Ns-substituted adenosines is as much as 1 order of magnitude greater. Such results suggest that a combination of appropriate modifications at N6 and C- 5'might additively augment the agonist potency of adenosine. At low temperatures 1- ...
