One of the major hurdles in the development of effective drugs targeting GPCRs is finding ligands selective for a specific receptor subtype. Here we describe a potent and selective hormone-basedhA3AR ligand (Kiof 167 nM) with a remarkable selectivity.

the past decades, they have been identified as potent and selective ligands for adenosinereceptor. In continuation of our project related to the syntheses of pharmacologically important heterocycles, a newseries of chromone–thiazole hybrids have been designed as potential ligands for human adenosinereceptors. In this context, new 4-oxo-N-(substituted-thiazol-2-yl)-4H-chromene-2-carboxamides were
摘要 Chromones 是 4H-benzopyran-4-one 杂环,由于其有趣的生物活性已被深入研究。长期以来,基于噻唑的化合物已作为抗微生物剂、抗病毒剂和抗真菌剂用于治疗,但在过去的几十年中,它们被确定为腺苷受体的有效和选择性配体。为了继续我们与药理学上重要的杂环化合物的合成相关的项目,已经设计了一系列新的色酮-噻唑杂化物作为人类腺苷受体的潜在配体。在这种情况下,新的 4-oxo-N-(取代-噻唑-2-基)-4H-色烯-2-甲酰胺通过两种不同的酰胺化方法从色酮-2-羧酸合成。不同合成方法的发展提供了在不同反应条件下工作的可能性,即传统加热和/或微波辐射。化合物的结构已在核磁共振和质谱和 X 射线晶体学的基础上确定。已获得与色酮-噻唑杂化物的分子几何形状和构象有关的相关数据,这对于理解配体-受体结合至关重要。
