YM155, a small imidazolium-based compound, potently inhibits survivin promoter activity with an IC50 value of 0.54nM [1]. YM155 can suppress survivin expression through the disruption of SP1 binding to the survivin core promoter and of ILF3–p54/nrb complex[2]. YM155 has been widely used to induce tumor cell apoptosis and promote tumor regression in diverse cell and animal models[3].
In vitro, YM155 treatment for 120 hours significantly inhibited the proliferation of UKF-NB-3 and UKF-NB-6 cells with IC50 values of 0.49 and 0.65nM, respectively[4]. Treatment of H1299 cells with YM155 at 40nM for 24h significantly induced cell death and promoted mitochondrial dysfunction, leading to a reduction in tricarboxylic acid (TCA) cycle intermediates[5]. Treatment with 10nM YM155 for 24 hours significantly inhibited PANC-1 cell viability and induced downregulation of PI3K, p-ERK, and p-STAT3 in PANC-1 cells[6].
In vivo, YM155 treatment via subcutaneous injection at a dose of 2 mg/kg/day for 21 days remarkably reduced tumor growth in the SH-SY5Y cell xenograft model of mice, without affecting body weight[7]. Continuous subcutaneous infusion of YM155 (5mg/kg/day) for 21 days significantly inhibited the development of ascites in Primary effusion lymphoma (PEL) xenograft mice[8].

YM155是一种基于imidazolium的小分子化合物,能有效抑制survivin启动子活性,IC50值为0.54nM[1]。YM155通过破坏SP1与survivin核心启动子的结合,以及干扰ILF3-p54/nrb复合物的形成,从而抑制survivin的表达[2]。YM155已广泛应用于多种细胞和动物模型中,用于诱导肿瘤细胞凋亡并促进肿瘤消退[3]。
在体外,YM155处理120小时可显著抑制UKF-NB-3和UKF-NB-6细胞的增殖,IC50值分别为0.49nM和0.65nM[4]。使用40nM YM155处理H1299细胞24小时,能显著诱导细胞死亡并促进线粒体功能障碍,导致三羧酸(TCA)循环中间产物减少[5]。用10nM的YM155处理PANC-1细胞24小时,可显著抑制细胞活力,并下调PI3K、p-ERK和p-STAT3的表达[6]。
在体内,每日皮下注射2 mg/kg/day剂量的YM155连续21天,能显著抑制SH-SY5Y细胞移植瘤小鼠的肿瘤生长,且不影响体重[7]。持续皮下输注YM155(5 mg/kg/day)21天,可显著抑制原发性渗出性淋巴瘤移植瘤小鼠腹水的形成[8]。
