The 6,6′-([2,2′:5′,2″:5″,2‴-quaterthiophene]-5,5‴-diyl)bis(1,3,5-triazine-2,4-diamine) (MR100), has been previously investigated in our research group through its biological activities toward pathogenic prion proteins (PrPSc). This compound presents a high affinity to protein strains and interacts selectively with at least one β-sheet rich isoform of prion protein. Herein we present the improved total
6,6'-([[2,2':5',2'':5“,2′-四噻吩] -5,5′-二基)双(1,3,5-三嗪-2,4-二胺)(MR100),之前已在我们的研究小组中通过其对致病性病毒蛋白(PrP Sc)的生物学活性进行了研究。该化合物对蛋白质菌株具有高亲和力,并与with病毒蛋白质的至少一种富含β-折叠的同工型选择性地相互作用。本文中,我们通过使用协同金属化去质子化机理(CMD)的钯催化的直接双芳基化反应,提出了MR100的改进的总合成方法。
