Staying in the pocket: A cyclometalated iridium(III) biquinoline complex targets the protein-protein interface (see picture; C yellow, N blue, Ir dark green) of the tumor necrosis factor-α (TNF-α) trimer. Molecular-modeling studies confirm the nature of this interaction. Both enantiomers of the iridium complex display comparable in vitro potency to the strongest small-molecule inhibitor of TNF-α.
环金属铱(III)双喹啉配合物靶向肿瘤坏死因子-α(TNF-α)三聚体的蛋白质-蛋白质界面(如图所示;C 黄色,N 蓝色,Ir 深绿色)。分子建模研究证实了这种相互作用的性质。该铱配合物的两种对映异构体在体外均表现出与最强的 TNF-α 小分子抑制剂相当的效力。
