substituted indolo[2,3-c]quinolone-6-ones was developed as simplified Lamellarin isosters. Synthesis was achieved from indole after a four-step pathway sequence involving iodination, a Suzuki-Miyaura cross-coupling reaction, and a reduction/lactamization sequence. The inhibitory activity of the 22 novel derivatives was assessed on Haspin kinase. Two of them possessed an IC50 of 1 and 2 nM with selectivity
摘要 取代吲哚[2,3 - c ]quinolone-6-ones 库被开发为简化的Lamellarin 等排体。在涉及碘化、Suzuki-Miyaura 交叉偶联反应和还原/内酰胺化序列的四步途径序列后,从吲哚合成。评估了 22 种新衍生物对 Haspin 激酶的抑制活性。其中两个具有 1 nM 和 2 nM 的 IC 50,对包括母体激酶 DYRK1A 和 CLK1 在内的 10 种其他激酶具有选择性。最具选择性的化合物还对骨肉瘤 U-2 OS 细胞系产生了非常有趣的细胞作用。
