The synthesis of oligo(ethylene glycol)-alkene substituted theophyllines in positions 7 and/or 8 is described. The binding activity at adenosine receptors of selected derivatives was studied. Compound 2 showed high affinity for human A2B receptor (Ki = 4.16 nM) with a selectivity KiA2A/KiA2B of 24.1, and a solubility in water of 1 mM. The alkenyl substituent in some of the theophyllinederivatives allows
描述了在7和/或8位的低聚(乙二醇)-烯烃取代的茶碱的合成。研究了所选衍生物对腺苷受体的结合活性。化合物2对人A 2B受体(K i = 4.16 nM)表现出高亲和力,选择性为K iA2A / K iA2B溶解度为24.1,在水中的溶解度为1 mM。一些茶碱衍生物中的烯基取代基允许它们通过氢化硅烷化共价连接到氢封端的硅底物表面上。或者,将叠氮基团掺入到寡聚(乙二醇)茶碱衍生物中作为锚定物,用于通过点击反应将乙炔基呈递表面上的分子束缚在一起。
