Polycyclic aromatic systems have been considered good biological probes, but some may also be good scaffolds for drug development. In this study, a series of benzobis(imidazole) derivatives were identified as STAT3 signal inhibitors, among which compound 24 showed significant inhibition of IL-6 induced JAK/STAT3 signalling pathway activation. Moreover, 24 inhibited cancer cell growth and migration

抑制剂,其中化合物24对IL-6诱导的JAK/STAT3信号通路激活有显着抑制作用。此外,24抑制癌细胞生长和迁移,并在人肝细胞癌细胞 (HepG2) 和食管癌细胞 (
EC109) 中诱导细胞凋亡以及周期停滞。化合物24在小鼠HepG2细胞异种移植肿瘤模型中也显示出明显的抗肿瘤活性而不影响体重。这些结果证实24是一种潜在的 STAT3 信号
抑制剂,具有一定的抗肿瘤活性。
