Dr. Borcherding et al., The synthesis and biological activity of a highly selective adenosine A(2a) receptor agonist, NUCLEOS NUC, 18(10), 1999, pp. 2175-2191
Three novel nucleosides 1, 2, and 3 were prepared that contained side chain
s at the 2-position of adenosine. Compound I was shown to be the most selec
tive A(2a) receptor agonist reported to date having an A(1)/A(2) ratio of 2
400. In addition, compound 1 was shown to reduce blood pressure in rats and
dogs with only minimal effects on heart rate.
