  A new orally bioavailable dual adenosine A2B/A3 receptor antagonist with therapeutic potential

  摘要：

  The synthesis and SAR of 5 -heterocycle- substituted aminothiazole adenosine receptor antagonists is described. Several compounds show high affinity and selectivity for the A(2B) and A(3) receptors. One compound (5f) shows good ADME properties in the rat and as such may be an important new compound in testing the current hypotheses proposing a therapeutic role for a dual A(2B)/A(3) antagonist in allergic diseases.
