  Design, Synthesis, and Structure−Activity Relationships of 1-,3-,8-, and 9-Substituted-9-deazaxanthines at the Human A_2B Adenosine Receptor

  摘要：

  Over two hundred 1-, 3-, 8-, and 9-substituted-9-deazaxanthines were prepared and evaluated for their binding affinity at the recombinant human adenosine receptors, in particular at the hA(2B) and hA(2A) subtypes. Several ligands endowed with sub-micromolar to low nanomolar binding affinity at hA(2B) receptors, good selectivity over hA(2A) and hA(3), but a relatively poor selectivity over hA(1) were obtained. Good antagonistic potencies and efficacies, with pA(2) values close to the corresponding pK(i)s, were observed in functional assays in vitro performed on a selected series of compounds. 1,3-Dimethyl-8-phenoxy-(N-p-halogenophenyl)-acetamido-9-deazaxanthine derivatives appeared as the most interesting leads, some of them showing outstanding hA(2B) affinities, high selectivity over hA(2A) and hA(3), but low selectivity over hA(1). Structure-affinity relationships suggested that the binding potency at the hA(2B) receptor was mainly modulated by the steric (lipophilic) properties of the substituents at positions 1 and 3 and by the electronic and lipophilic characteristics of the substituents at position 8. A comparison among affinity and selectivity profiles of 9-deazaxanthines with the corresponding xanthines suggested some possible differences in their binding mode.

  New pyrrolopyrimidin-6-yl benzenesulfonamides: Potent A2B adenosine receptor antagonists

  摘要：

  A new series of 4-(1,3-dialkyl-2,4-dioxo-2,3,4,5-tetrahydro-1H-pyrrolo[3,2-d]pyrimidin-6-yl)benzenesulfonamides has been identified as potent AZB adenosine receptor antagonists. The products have been evaluated for their binding affinities for the human A(2B), A(1) and A(3) adenosine receptors. 6-(4-{[4-(4-Bromobenzyl)piperazin-1-yl]sulfonyl}phenyl)-1,3-dimethyl-1H-pyrrolo[3,2-d]pyrimidine-2,4(3H,5H)-dione (16) showed a high affinity for the AZB adenosine receptor (IC50 = 1 nM) and selectivity (A(1): 183x; A(30): 12660x). Synthesis and SAR of this novel class of compounds showing improved absorption properties is presented herein. (c) 2006 Elsevier Ltd. All rights reserved.

  A number of 1,3-dialkyl-9-deazaxanthines (9-dAXs), bearing a variety of N-substituted benzyloxycarbonylamino substituents at position 8, were prepared and evaluated for their binding affinity to the recombinant human adenosine receptors (hARs), chiefly to the hA(2B) and hA(2A) AR subtypes. Several ligands endowed with excellent binding affinity to the hA2B receptors, but low selectivity versus hA2A and hA(1) were identified. Among these, 1,3-dimethyl-N-30-thienyl carbamate 15 resulted as the most potent ligand at hA(2B) (K-i = 0.8 nM), with a low selectivity versus hA(2A) (hA(2A)/hA(2B) = 12.6) and hA(1) (hA(1)/hA(2B) = 12.5) and a higher selectivity versus hA(3) (hA(3)/hA(2B) = 454). When tested in functional assays in vitro, compound 15 exhibited high antagonist activities and efficacies versus both the A(2A) and A(2B) receptor subtypes, with pA(2) values close to the corresponding pK(i)s. A comparative analysis of structure - affinity and structure selectivity relationships of the similar analogues 8-N-substituted benzyloxycarbonylamino- and 8-N-substituted phenoxyacetamido-9-dAXs suggested that their binding modes at the hA(2B) and hA(2A) ARs may strongly differ. Computational studies help to clarify this striking difference arising from a simple, albeit crucial, structural change, from CH2OCON to OCH2CON, in the para-position of the 8-phenyl ring.

  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).
