Phen-DC3 Trifluoromethanesulfonate (C09-1164-905)

Phen-DC3 Trifluoromethanesulfonate is a G-quadruplex (G4) specific ligand which can inhibit FANCJ and DinG helicases with IC 50 s of 65±6 and 50±10 nM, respectively.In VitroIn 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. MCE has not independently confirmed the accuracy of these methods. They are for reference only.Cell AssayBriefly, untreated WT cells and pif1 Δ cells from a fresh patch of cells get from a single colony bearing the parental allele size are diluted in 5 mL of YPD (2×10 5 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. MCE has not independently confirmed the accuracy of these methods. They are for reference only.Form:SolidIC50& Target:IC50: 65±6 nM (G4 substrate, FANCJ helicase), 50±10 nM (G4 substrate, DinG helicases). Specifications and Purity: 98%.
