The synthesis and the binding affinity for the putative adenosine receptor antagonist 6-methyl-7-[1,2,3]triazol-2-yl-1,6-dihydrobenzo[1,2-d;3,4-dâ²]diimidazole (10) and 5-oxazol-2-yl-1H-pyrazolo[4,3-b]pyridin-3-ylamine (16) are reported. The title compounds were prepared from commercially available 1-chloro-2,4-dinitrobenzene (1) and 2-chloro-6-methoxy-3nitropyridine (11), respectively, but proved devoid of affinity for the adenosine A1 and A2A receptors.
报告了假定腺苷受体拮抗剂6-甲基-7-[1,2,3]三唑-2-基-1,6-二氢苯并[1,2-d;3,4-d′]二咪唑(10)和5-噁唑-2-基-1H-吡唑[4,3-b]吡啶-3-基胺(16)的合成及其结合亲和力。这些标题化合物分别由商业可得的1-氯-2,4-二硝基苯(1)和2-氯-6-甲氧基-3-硝基吡啶(11)制备而成,但对腺苷A1和A2A受体未表现出亲和力。
