modulators that we previously showed to induce potent growth inhibition in pancreatic ductal adenocarcinoma (PDAC) cell lines. Our lead optimization campaign yielded QD325 as the most potent redox modulator candidate inducing substantial reactive oxygen species (ROS) in PDAC cells. Nascent RNA sequencing following treatments with the QD compounds revealed induction of stress responses in nucleus, endoplasmic
改变氧化还原稳态可以为胰腺癌的治疗提供独特的治疗机会。喹唑啉二酮(QDs)是新颖的氧化还原调节剂,我们先前已证明在胰腺导管腺癌(PDAC)细胞系中诱导有效的生长抑制作用。我们的领先优化活动使QD325成为最有力的氧化还原调节剂候选物,可在PDAC细胞中诱导大量的活性氧(ROS)。QD化合物处理后的新生RNA测序表明,胰腺癌细胞核,内质网和线粒体中应激反应的诱导。此外,QD化合物诱导Nrf2介导的氧化应激和未折叠的蛋白质反应,如代表性基因(如NQO1,HMOX1,DDIT3和HSPA5。在较高浓度下,量子点通过抑制mtDNA转录并下调mtDNA编码的OXPHOS酶来阻断线粒体功能。重要的是,QD325的治疗在体内具有良好的耐受性,并显着延迟了小鼠的肿瘤生长。我们的研究支持QD325作为PDAC治疗的新疗法的开发。
