tumorigenesis of NSCLC, developing antitumor small molecules that can suppress the expression of Twist1 is of far-reaching significance for the treatment of NSCLC. A series of novel benzo[d]imidazo[2,1-b]thiazole derivatives possessing 1,3,4-oxadiazole moiety were designed based on the structure of the first-in-class Twist1 inhibitor harmine. Among the synthetic twenty-two compounds, the compound containing 2-(piperidine-1-yl)
标准化疗和个性化靶向治疗常用于晚期非小细胞肺癌 (NSCLC) 患者。然而,多药耐药(MDR)和肿瘤转移导致治疗效果下降,这与上皮间质转化(
EMT)密切相关。Twist1 是一种
EMT 转录因子,在促进
EMT、MDR 和肿瘤转移中起重要作用。鉴于Twist1在NSCLC肿瘤发生中的重要作用,开发能够抑制Twist1表达的抗肿瘤小分子对于NSCLC的治疗具有深远意义。一系列新型苯并[ d ]
