xanthine derivatives. Therefore, the developed 8-benzylaminoxanthine scaffold seems to be highly selective for AR activity and relevant for potent and selective A2A ligands. Compound 12d with high selectivity for ARs, especially for the A2AAR subtype, evaluated in animal models of inflammation has shown anti-inflammatory activity. Investigated compounds were found to display high selectivity and may
在生物学研究中探索了基于黄嘌呤骨架的34种新化合物的文库,用于与腺苷受体(ARs)相互作用。黄嘌呤核的结构修饰被引入8位(苄氨基和苄氧基取代)以及N 1,N 3和N 7(小的烷基残基),从而提高了对A 2A AR的亲和力和选择性。通过放射性配体结合试验对化合物进行了表征,我们的研究导致开发了有效的A 2A AR配体,其中包括8-((6-氯-2-氟-3-甲氧基苄基)氨基)-1-乙基-3,7 -二甲基-3,7-二氢-1 H-嘌呤-2,6-二酮(12d ; K i人A 2A AR:68.5 nM)和8-((2-氯苄基)氨基)-1-乙基-3,7-二甲基-3,7-二氢-1 H-嘌呤-2,6-二酮(12 h ; K i人A 2A AR:71.1 nM)。此外,在1,3-二乙基-7-甲基黄嘌呤衍生物的组中鉴定出双A 1 / A 2A AR配体。化合物14b的显示ķ我为A值52.2 NM的1 AR和167
