  Fast and highly efficient one-pot synthesis of 9-deazaxanthines

  摘要：

  SnCl2 enables a direct, high-yield conversion of 5-nitro-1,3-dialkyl-6-styryl(furyl-, thienyl-vinyl)-uracils to 8-substituted-9-deazaxanthines under very mild experimental conditions. The method has a general applicability and it is compatible with the reactivity of the most common organic functional groups. In slightly experimental different conditions, it allows a high-yield and fast (<5 min) preparation of pure 7-N-hydroxy-9-deazaxanthines. (C) 2003 Elsevier Science Ltd. All rights reserved.

  A number of 1,3-dialkyl-8-(hetero)aryl-9-OH-9-deazaxanthines were prepared and evaluated as ligands of recombinant human adenosine receptors (hARs). Several 1,3-dipropyl derivatives endowed with nano-molar binding affinity at hA(2B) receptors, but poor selectivity over hA(2A), hA(1) and hA(3) AR subtypes were identified. A comparison with the corresponding 7-OH- and 7,9-unsubstituted-deazaxanthines revealed that 9-OH-9-deazaxanthines are more potent hA(2B) ligands with lower partition coefficients and higher water solubility compared to the other two congeneric classes of deazaxanthines. An optimization of the para-substituent of the 8-phenyl ring of 9-OH-9-deazaxanthines led to the discovery of compound 38, which exhibited outstanding hA(2B) affinity (Ki = 1.0 nM), good selectivity over hA(2A), hA(1) and hA(3) (selectivity indices = 100, 79 and 1290, respectively) and excellent antagonist potency in a functional assay on rat A(2B) (pA(2B) = 9.33).
