Description

APTO-253 is an inducer of Kruppel-like factor 4 (KLF4), and also stabilizes Gquadruplex, with anti-proliferative activity.

IC50 & Target

KLF4[1], Gquadruplex[3]

In Vitro

APTO-253 is an inducer of KLF4. APTO-253 (5 μM) induces KLF4 expression, and enhances apoptosis induced by cisplatin in both SKOV3 and OVCAR3 cells. APTO-253 (5 μM) also leads to G1 phase arrest and reduces S and G2/M phase cells in SKOV3 and OVCAR3 cells[1]. APTO-253 is cytotoxic to Raji and Raji/253R cell lines, with IC50s of 105 ± 2.4 nM and 1387 ± 94 nM, respectively. APTO-253 (0.5 μM) also causes DNA damage in Raji cells. BRCA1/2 deficient cells are hypersensitive to APTO-253. ABCG2 overexpressed HEK-293 cells are resistant to APTO-253 and inhibition of ABCG2 reverses resistance to APTO-253 in Raji/253R[2]. APTO-253 suppresses the proliferation of acute myeloid leukemia (AML) cell lines and various forms of lymphoma cell lines with IC50s ranging from 57 nM to 1.75 µM. APTO-253 (500 nM) also causes G0/G1 cell cycle arrest, induces apoptosis, and down regulates MYC RNA and protein expression 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 Gquadruplex (G4) motifs, and demonstrates the greatest propensity for stabilizing the MYC G4 sequences[3].

Cell Assay
[3]

APTO-253 is dissolved in DMSO[3].

Cells are plated and treated with vehicle DMSO or APTO-253 (10 concentrations) in 96 well plates for 5 days at 37°C and 5% CO2. Cell viability is measured using CellTiter 96® AQueous one solution cell proliferation assay, and IC50 values are calculated using GraphPad Prism 7 software[3].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
