the prodrug of baloxavir (2) and a cap-dependent endonuclease (CEN) inhibitor, were approved by the FDA for the first treatment in almost 20 years. Despite their high antiviral potency, drug-resistant variants have been observed in clinical trials. Herein, we report a novel CEN inhibitor 8 with a delicately designed macrocyclic scaffold that exhibits a significantly smaller shift of inhibitory activity
流感病毒 (IFV) 自 20 世纪初首次记录以来,已经引起了多次大流行,并夺走了无数人的生命。虽然 COVID-19 的爆发似乎在短时间内将流感从人们的视线中驱逐出去,但在冠状病毒变异成致命性较低的变体后,它将在全球范围内重新传播也就不足为奇了。Baloxavir marboxil (1) 是 baloxavir (2) 的前药和帽依赖性核酸内切酶 (CEN) 抑制剂,被 FDA 批准用于近 20 年来的首次治疗。尽管耐药性变体具有很高的抗病毒效力,但在临床试验中已观察到耐药变体。在此,我们报道了一种新型 CEN 抑制剂 8,该抑制剂具有精心设计的大环支架,其抑制活性向 baloxavir 耐药变体的转变显着减小。
