Overactivation of neddylation has been found in a number of common human tumor-related diseases. In recent years, targeting the neddylation pathway has become an appealing anti-cancer strategy, and it is critical to find neddylation inhibitors with novel structures and higher efficacy. Here, we present the discovery of novel inhibitors of the NEDD8-activating enzyme (NAE) and their antitumor activity
在许多常见的人类肿瘤相关疾病中发现了neddylation的过度激活。近年来,针对neddylation途径已成为一种颇具吸引力的抗癌策略,寻找结构新颖、疗效更高的neddylation抑制剂至关重要。在这里,我们介绍了 NEDD8 激活酶 (NAE) 新型抑制剂的发现及其抗肿瘤活性。评估所有合成的 1,4-二取代哌啶化合物对 MGC-803、MCF-7、A549 和 KYSE-30 细胞的抗增殖活性。在五个代表性化合物中,带有喹唑啉基序的 III-26 被确定为主要化合物,因为它显着阻碍了 Cullin1 的 neddylation。细胞机制阐明,III-26 抑制 UBC12 过表达的 MGC-803 细胞系的增殖、迁移和侵袭,并诱导细胞凋亡并将细胞周期阻滞在 G2/M 期。重要的是,III-26 降低了 NAE 活性,从而选择性地防止 Cullin3 和 Cullin1 相对于其他 Cullin
