unclear. A medium throughput screen led to the identification of N-(2(-9H-carbazol-1-yl)phenyl)acetamide (GeA-69, 1) as a novel allosteric PARP14 MD2 (second MD of PARP14) inhibitor. We herein report medicinal chemistry around this novel chemotype to afford a sub-micromolar PARP14 MD2 inhibitor. This chemical series provides a novel starting point for further development of PARP14 chemical probes.

重组。PARP14包含三个(
ADP核糖结合)宏域(MD),尚不清楚其对病理学中整个PARP14功能的确切贡献。中等通量筛选导致鉴定出N-(2(-9H-

抑制剂。我们在此报告了围绕这种新型
