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.
聚腺苷二磷酸核糖聚合酶14(PARP14)已牵涉到DNA损伤反应途径中的同源重组。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-咔唑-1-基)苯基)乙酰胺(GeA-69,1)作为新型变构PARP14 MD2(PARP14的第二个MD)抑制剂。我们在此报告了围绕这种新型化学型的药物化学,以提供亚微摩尔的PARP14 MD2抑制剂。该化学系列为进一步开发PARP14化学探针提供了新的起点。
