Antagonists of adenosine receptor are under exploration as potential drug candidates for treatment of neurological disorders, depression, certain cancers and potentially used as a cancer immunotherapy. Herein, we describe design and synthesis of novel scaffold benzo[4,5]imidazo [1,2-a]pyrazin-1-amine (6) derivatives. All the compounds were evaluated for A2A AR antagonist activity and displayed encouraging
腺苷受体的拮抗剂正在探索作为治疗神经系统疾病,抑郁症,某些癌症的潜在候选药物,并有可能用作癌症免疫疗法。在这里,我们描述了新型支架苯并[4,5]咪唑并[1,2 - a ]吡嗪-1-胺(6)衍生物的设计和合成。对所有化合物的A 2A AR拮抗剂活性进行了评估,并在生化分析中显示出令人鼓舞的A 2A AR拮抗剂结合亲和力结果(IC 50 9–300 nM)。化合物27在A 2A AR拮抗剂cAMP功能测定(IC 5031 nM),并且该化合物在IL-2产生试验(EC 50 165 nM)时显示T细胞活化。进行了分子对接研究以合理化所观察到的化合物27的结合亲和力。
