Sherbiny, Farag F. published the artcileHomology modelling of the human adenosine A2B receptor based on x-ray structures of bovine rhodopsin, the β2-adrenergic receptor and the human adenosine A2A receptor, Category: amides-buliding-blocks, the publication is Journal of Computer-Aided Molecular Design (2009), 23(11), 807-828, database is CAplus and MEDLINE.

A three-dimensional model of the human adenosine A2B receptor was generated by means of homol. modeling, using the crystal structures of bovine rhodopsin, the β2-adrenergic receptor, and the human adenosine A2A receptor as templates. In order to compare the three resulting models, the binding modes of the adenosine A2B receptor antagonists theophylline, ZM241385, MRS1706, and PSB601 were investigated. The A2A-based model was much better able to stabilize the ligands in the binding site than the other models reflecting the high degree of similarity between A2A and A2B receptors: while the A2B receptor shares about 21% of the residues with rhodopsin, and 31% with the β2-adrenergic receptor, it is 56% identical to the adenosine A2A receptor. The A2A-based model was used for further studies. The model included the transmembrane domains, the extracellular and the intracellular hydrophilic loops as well as the terminal domains. In order to validate the usefulness of this model, a docking anal. of several selective and nonselective agonists and antagonists was carried out including a study of binding affinities and selectivities of these ligands with respect to the adenosine A2A and A2B receptors. A common binding site is proposed for antagonists and agonists based on homol. modeling combined with site-directed mutagenesis and a comparison between exptl. and calculated affinity data. The new, validated A2B receptor model may serve as a basis for developing more potent and selective drugs.
