the hERG potassium ion channel can accommodate large, structurally diverse compounds that can be trapped in the channel by closure of the activation gate. A small set of propafenone derivatives was synthesized, and both use‐dependency and recovery from block were tested in order to gain insight into the behavior of these compounds with respect to trapping and non‐trapping. Ligand–protein docking into
hERG钾离子通道的内腔可以容纳结构上多样的大型化合物,这些化合物可以通过关闭激活门而被捕获在通道中。合成了一小批普罗帕酮衍生物,并测试了其依赖性和从嵌段中回收,以深入了解这些化合物在捕集和非捕集方面的行为。配体-蛋白质对接到hERG通道关闭和打开状态的同源性模型中,为药物捕获的分子基础提供了第一个证据。
