A novel series of pyrido[2,3-d]pyrimidines; pyrido[3,2-e][1,3,4]triazolo; and tetrazolo[1,5-c]pyrimidines were synthesized via different chemical transformations starting from pyrazolo[3,4-b]pyridin-6-yl)-N,N-dimethylcarbamimidic chloride 3b (prepared from the reaction of o-aminonitrile 1b and phosogen iminiumchloride). The structures of the newly synthesized compounds were elucidated based on spectroscopic
一系列新的吡啶并[2,3-d]嘧啶;吡啶并[3,2-e][1,3,4]三唑基;和四唑并[1,5-c]嘧啶通过不同的化学转化从吡唑并[3,4-b]吡啶-6-基)-N,N-二甲基氨基甲酰氯3b开始合成(由o-氨基腈1b的反应制备)和光原亚胺氯化物)。基于光谱数据和元素分析阐明了新合成化合物的结构。使用Auto Dock Vina软件对指定化合物进行分子对接,以评估合成化合物对SARS-CoV-2(2019-nCoV)主要蛋白酶M pro的抗病毒效力。针对 SARS-CoV-2 的抗病毒活性表明,与洛匹那韦相比,测试的化合物 7c、7d 和 7e 具有最有前途的抗病毒活性,IC50 值较低,”
