(p-ERK), protein kinase B (Akt), and signal transducer and activator of transcription 3 (STAT3). Furthermore, they increased reactive oxygen species (ROS) levels in A549 cells; however, pretreatment with the ROS inhibitor N-acetyl-l-cysteine significantly inhibited EPDMNQ- and ENDMNQ-mediated apoptosis and reversed apoptotic proteins expression. In conclusion, EPDMNQ and ENDMNQ induced G1 phase cell cycle
天然化合物1,4-萘醌具有有效的抗肿瘤活性。但是,1,4-萘醌及其衍生物的临床应用受到其副作用的限制。在这项研究中,我们尝试通过合成两种衍生物来降低1,4-萘醌的毒性:2,3-二氢-2,3-环氧-2-丙磺酰基-5,8-二甲氧基-1,4-萘醌(EPDMNQ )和2,3-二氢-2,3-环氧-2-壬基磺酰基-5,8-二甲氧基-1,4-萘醌(ENDMNQ)。然后,我们评估了这些化合物在肺癌细胞中的细胞毒性和分子机制。EPDMNQ和ENDMNQ显着抑制了三种肺癌细胞株的活力,并诱导了A549细胞周期停滞在G1期。此外,他们通过增加p38和c-Jun N端激酶(p-JNK)的磷酸化来诱导A549肺癌细胞凋亡,并减少细胞外信号相关激酶(p-ERK),蛋白激酶B(Akt)以及信号转导和转录激活因子3(STAT3)的磷酸化。此外,它们增加了A549细胞中的活性氧(ROS)水平。但是,用ROS抑制剂N-乙酰基
