adenosine A2A receptors (A2ARs) antagonists have profound therapeutic efficacy in Parkinsons Disease (PD) by improving dopamine transmission, thus being active in reversing motor deficits and extrapyramidal symptoms related to the disease. Therefore, in the presents study, we have showed the development of novel 1,3,5-triazine-thiadiazole derivative as potent A2AARs antagonist. In the radioligand binding
各种研究表明,腺苷A 2 A受体(A 2 ARs)拮抗剂可通过改善多巴胺的传播而在帕金森病(PD)中具有深远的治疗功效,因此在逆转运动缺陷和与该疾病相关的锥体外系症状方面具有活性。 因此,在本研究中,我们显示了新型的1,3,5-三嗪-噻二唑衍生物作为有效的A 2 AARs拮抗剂的发展。在放射性配体结合测定中,与A 1 R相比,这些分子显示出与A 2 AR的优异结合亲和力,并且具有显着的选择性。结果表明,化合物7e是测试系列中最有效的A 2 AR拮抗剂。在与A 2 AR蛋白模型对接分析中,化合物7e通过与His264,Tyr271,His278,Glu169,Ala63,Val84,Ile274,Met270和Phe169进行多次原子间接触,发现其被深深地埋入衬里的受体腔中。总的来说,我们的研究证明了1,3,5-三嗪-噻二唑杂合体是设计新型A 2 A拮抗剂的高效支架。
