New therapies for treating coronaviruses are urgently needed. A series of 4-anilino-6-aminoquinazoline derivatives were synthesized and evaluated to show high anti-MERS-CoV activities. N4-(3-Chloro-4-fluorophenyl)-N6-(3-methoxybenzyl)quinazoline-4,6-diamine (1) has been identified in a random screen as a hit compound for inhibiting MERS-CoV infection. Throughout optimization process, compound 20 was
迫切需要治疗冠状病毒的新疗法。合成并评估了一系列 4-苯胺基-6-氨基喹唑啉衍生物,显示出高抗 MERS-CoV 活性。N 4 -(3-氯-4-氟苯基)- N 6 -(3-甲氧基苄基)喹唑啉-4,6-二胺 ( 1 ) 已在随机筛选中被鉴定为抑制 MERS-CoV 感染的热门化合物。在整个优化过程中,发现化合物20表现出高抑制作用(IC 50 = 0.157 μM,SI = 25),无细胞毒性,体内PK 特性适中。
