  In Vitro Pharmacokinetic Optimizations of AM2-S31N Channel Blockers Led to the Discovery of Slow-Binding Inhibitors with Potent Antiviral Activity against Drug-Resistant Influenza A Viruses

  摘要：

  Influenza viruses are respiratory pathogens that are responsible for both seasonal influenza epidemics and occasional influenza pandemics. The narrow therapeutic window of oseltamivir, coupled with the emergence of drug resistance, calls for the next-generation of antivirals. With our continuous interest in developing AM2-S31N inhibitors as oral influenza antivirals, we report here the progress of optimizing the in vitro pharmacokinetic (PK) properties of AM2-S31N inhibitors. Several AM2-S31N inhibitors, including compound 10b, were discovered to have potent channel blockage, single to submicromolar antiviral activity, and favorable in vitro PK properties. The antiviral efficacy of compound 10b was also synergistic with oseltamivir carboxylate. Interestingly, binding kinetic studies (K-d, K-on, and K-off) revealed several AM2-S31N inhibitors that have similar K-d values but significantly different K-on and K-off values. Overall, this study identified a potent lead compound (10b) with improved in vitro PK properties that is suitable for the in vivo mouse model studies.

  With the emergence of highly pathogenic avian influenza (HPAI) H7N9 and H5N1 strains, there is a pressing need to develop direct-acting antivirals (DAAs) to combat such deadly viruses. The M2-S31N proton channel of the influenza A virus (A/M2) is one of the validated and most conserved proteins encoded by the current circulating influenza A viruses; thus, it represents a high-profile drug target for

  随着高致病性禽流感 (HPAI) H7N9 和 H5N1 毒株的出现，迫切需要开发直接作用抗病毒药物 (DAA) 来对抗此类致命病毒。甲型流感病毒 (A/M2) 的 M2-S31N 质子通道是目前流行的甲型流感病毒编码的经过验证和最保守的蛋白质之一；因此，它代表了治疗干预的重要药物靶点。我们最近发现了一系列具有金刚烷基-1-NH 2 + CH 2 -芳基结构的S31N抑制剂，但它们的物理性质普遍较差，部分在体外表现出毒性。在这项研究中，我们试图优化金刚烷基和芳基/杂芳基。本研究中的几种化合物表现出亚微摩尔 EC在选择性指数大于 100 的抗病毒斑块减少试验中，针对含有 S31N 的 A/WSN/33 流感病毒的50值表明这些化合物是深入临床前药理学的有希望的候选物。
