氮杂吲哚类PARP-1抑制剂的合成及活性评价

Synthesis and activity evaluation of PARP-1 inhibitors with azaindole skeleton

PARP-1通过催化ADP-核糖单元(ADP-ribose)从烟酰胺腺嘌呤二核苷酸(nicotinamide adenine dinucleotide,NAD+)转移至各种底物蛋白上,参与损伤DNA的修复过程,是潜在的新机制的抗肿瘤药物靶标。本文设计合成了新结构氮杂吲哚类目标化合物16个,获得了对PARP-1具有抑制活性的化合物8个,其中2-位为脂环胺取代的氮杂吲哚对PARP-1和PARP-2均有抑制活性。

PARP [poly（ADP-ribose）polymerase] represents a novel potential target in cancer therapy. It is involved in a DNA repair process by catalyzing the transfer of ADP-ribose units from NAD ~ to a number of its substrate proteins. In this work, a series of novel azaindole derivatives was designed and synthesized. Moreover, 16 target molecules were screened and 8 compounds displayed inhibitory activity against PARP-1. It has been demonstrated that these azaindoles bearing cycloamine substituents at 2-position were active to both PARP-1 and PARP-2.
