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].
