a class 2 atropisomer (intermediate conformational exchange). It was further found by X-ray crystallography that one enantiomer of a compound bound to the intended HCV NS5B polymerase target whereas the mirror image atropisomer was able to bind to an unrelated HIV matrix target. Analogues were then identified that selectively inhibited the former. These studies highlight that atropisomer chirality
通过 X 射线晶体学进一步发现,化合物的一种对映异构体与预期的 HCV NS5B 聚合酶靶标结合,而镜像阻转异构体能够与不相关的 HIV 基质靶标结合。然后鉴定出选择性抑制前者的类似物。这些研究强调,阻转异构体手性可以导致具有特定特性的不同实体,药物发现中的阻转异构现象应进行评估和适当管理。
