The discovery of new drugs for the treatment of neurodegenerative disorders, such as Parkinson's disease, has become an attractive field of research. Due to the regulation of D(2) receptor activity by A(2A) adenosine receptor, potent and selective ligands of A(2A) subtype could be useful tools to study neurodegenerative disorders. A series of 2,8-disubstituted-9-ethyladenine derivatives was synthesized
用于治疗神经退行性疾病如帕金森氏病的新药物的发现已成为有吸引力的研究领域。由于A(2A)腺苷受体对D(2)受体活性的调节,A(2A)亚型的有效和选择性配体可能是研究神经退行性疾病的有用工具。合成了一系列2,8-二取代-9-乙基腺嘌呤衍生物,并在结合亲和力测定中在人腺苷受体上进行了测试。与其他亚型相比,新化合物对A(2A)受体表现出良好的亲和力和选择性。在8位上引入溴原子会增加这些化合物的亲和力,从而导致配体在纳摩尔范围内具有K(i)。
