Phen-DC3 Trifluoromethanesulfonate is a G-quadruplex (G4) specific ligand which can inhibit FANCJ and DinG helicases with IC₅₀s of 65±6 and 50±10 nM, respectively.

IC50: 65±6 nM (G4 substrate, FANCJ helicase), 50±10 nM (G4 substrate, DinG helicases)^[1]

In WT cells, a CEB1-WT array is rather stable but undergoes frequent rearrangements upon addition of 10 μM Phen-DC3 Trifluoromethanesulfonate (Phen-DC3). It is found that the c-Myc allele exhibits significant destabilization upon Phen-DC3 Trifluoromethanesulfonate treatment and PIF1 deletion. The CEB25-L111(T) array is stable in WT cells, it becomes unstable upon addition of Phen-DC3 Trifluoromethanesulfonate or deletion of PIF1. It is also highly destabilized in the presence of Phen-DC3 Trifluoromethanesulfonate or in the absence of PIF1. The CEB1-loop CEB25 allele remaines fully stable in both PIF1-treated and WT cells^[2].

Briefly, untreated WT cells and pif1Δ cells from a fresh patch of cells get from a single colony bearing the parental allele size are diluted in 5 mL of YPD (2×10⁵ cells/mL), grown for 8 generations at 30°C with shaking, and spreaded as single colony on YPD plates. To measure minisatellite instability upon Phen-DC3 Trifluoromethanesulfonate treatment, WT cells from a fresh patch on YPD are grown for 8 generations at 30°C in liquid SC containing Phen-DC3 Trifluoromethanesulfonate at 10 μM. Isolated colonies or pools of colonies are analyzed by Southern blot using the EcoRI digestion that cuts at each side of the minisatellite^[2].
