In Vitro	Pyridostatin is a G-quadruplexe stabilizer, with a Kd of 490 nM[1]. Pyridostatin (PDS) shows neurotoxic activity against primary cortical neurons at 0.01-5 μM, causes DNA double-strand breaks (DSBs) at 1 μM, downregulates BRCA1 in neurons at 1, 2 or 5 μM[2]. Pyridostatin interacts with G-quadruplex motifs in SRC and alters mRNA levels of damaged genes[3].
Cell Assay	Cells are plated at equal confluence and either untreated or treated with 2 μM Pyridostatin continually for 72 h. Cells from individual plates are trypsinized and counted in a Coultercounter. Graphs represent total cell numbers at each time interval and error bars represent S.E.M. Data represent three independent experiments[3].
