360A iodide is a selective stabilizer of G-quadruplex and inhibits telomerase activity (IC50: 300 nM in TRAP-G4 assay).

Telomerase:300 nM

In brief, cells are seeded at various densities, depending on cell type (0.25-4 × 10^3 cells/well in 100?μL complete medium), in 96-well culture plates and treated with various concentrations (0.1-20?μM) of 360A or the corresponding concentrations of DMSO (control wells) for 3 or 7 days at 37°C in an atmosphere containing 5% CO2. For 7-day assays, the medium is changed on day 3. Experiments are performed in triplicate [1].
