emergence of drug-resistant viruses make essential the development of new anti-flu agents with novel mechanisms of action. One of the most attractive targets is the interaction between two subunits of the RNA-dependent RNA polymerase, PA and PB1. Herein we report the rational design of hybrid compounds starting from a 3-cyano-4,6-diphenylpyridine scaffold recently identified as disruptor of PA-PB1 interactions
针对流感病毒的有限治疗选择以及对耐药性病毒不断出现的日益增长的公共健康问题,使得具有新型作用机制的新型抗流感药的开发至关重要。最吸引人的靶标之一是RNA依赖性RNA聚合酶PA和PB1的两个亚基之间的相互作用。在本文中,我们报告了从最近被鉴定为PA-PB1相互作用破坏者的3-氰基-4,6-二苯基吡啶骨架开始的杂合化合物的合理设计。在先前报道的SAR数据的指导下,合成了氨基酸衍生物库。生物学评估导致鉴定出新的PA-PB1抑制剂,这些抑制剂没有明显的毒性。分子模型进一步阐明了这些化合物的抑制机理。
