  Does the combination of optimal substitutions at the C2-, N5- and N8-positions of the pyrazolo-triazolo-pyrimidine scaffold guarantee selective modulation of the human A3 adenosine receptors?

  摘要：

  In an attempt to study the optimal combination of a phenyl ring at the C-2-position and different substituents at the N-5- and N-8-positions towards the selective modulation of human A(3) adenosine receptors (hA(3)AR), we synthesized a new series of 2-para-(un)substituted-phenyl-pyrazolo-triazolo-pyrimidines bearing either a methyl or phenylethyl at N-8 and chains of variable length at N-5. Through biological evaluation, it was found that the majority of the compounds had good affinities towards the hA(3)AR in the low nanomolar range. Compound 16 possessed the best hA(3)AR affinity and selectivity profile (K(i)hA(3) = 1.33 nM; hA(1)/hA(3) = 4880; hA(2A)/hA(3) = 1100) in the present series of2-(substituted)phenylpyrazolo-triazolo-pyrimidine derivatives. In addition to pharmacological characterization, a molecular modeling investigation on these compounds further elucidated the effect of different substituents at the pyrazolo-triazolo-pyrimidine scaffold on affinity and selectivity to hA3AR.
