APTO-253 (5 M) induces KLF4 expression, and enhances apoptosisinduced by cisplatin in both

4、 SKOV3 and OVCAR3 cells. APTO-253 (5 M) also leads to G1 phase arrest andreduces S and G2/M phase cells in SKOV3 and OVCAR3 cells 1. APTO-253 is cytotoxic to Raji andRaji/253R cell lines, with IC50s of 105 2.4 nM and 1387 94 nM, respectively. APTO-253 (0.5 M) alsocauses DNA damage in Raji cells. BRC

5、A1/2 deficient cells are hypersensitive to APTO-253. ABCG2overexpressed HEK-293 cells are resistant to APTO-253 and inhibition of ABCG2 reverses resistance toAPTO-253 in Raji/253R 2. APTO-253 suppresses the proliferation of acute myeloid leukemia (AML) celllines and various forms of lymphoma cell li

6、nes with IC50s ranging from 57 nM to 1.75 M. APTO-253 (500nM) also causes G0/G1 cell cycle arrest, induces apoptosis, and down regulates MYC RNA and proteinexpression in AML lines. APTO-253 (500 nM) leads to DNA damage response pathways in MV4-11 cells.Futhermore, APTO-253 is a potent stabilizer of

7、Gquadruplex (G4) motifs, and demonstrates the greatestpropensity for stabilizing the MYC G4 sequences 3.PROTOCOLCell Assay 3 Cells are plated and treated with vehicle DMSO or APTO-253 (10 concentrations) in 96 well plates for 5 daysat 37C and 5% CO2. Cell viability is measured using CellTiter 96 AQu

8、eous one solution cell proliferationassay, and IC50 values are calculated using GraphPad Prism 7 software 3.MCE has not independently confirmed the accuracy of these methods.
