摘要
MRE 2029-F20 [N-benzo[1,3]dioxol-5-yl-2-[5-(2,6-dioxo-1,3-dipropyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-1-methyl-1H-pyrazol-3-yloxy]-acetamide] is a selective antagonist ligand of A(2B) adenosine receptors. For use as a radioligand, 1,3-diallyl-xanthine, the precursor of [H-3]-MRE 2029-F20, was synthesized, and tritiated on the allyl groups. [H-3]-MRE 2029-F20 bound to human A(2B) receptors expressed in CHO cells showed a K-D value of 1.65 +/- 0.10 nM and B-max value of 36 +/- 4 fmol/mg protein. [H-3]-MRE2029-F20 represents a useful tool for the pharmacological characterization of human A(2)B adenosine receptor subtype. (C) 2004 Elsevier Ltd. All rights reserved.
