Pyridostatin (RR82) is a G-quadruplex DNA stabilizing agent (Kd=490 nM) and can target DNA and RNA G4s in cells. Pyridostatin promotes growth arrest in human cancer cells by inducing replication- and transcription-dependent DNA damage. Pyridostatin targets the proto-oncogene Src. Pyridostatin reduced SRC protein levels and SRC-dependent cellular motility in human breast cancer cells.

     Stacked bar graphs of zebrafish embryos in dead, deformd, and normal status with different G4 stabilizer (Pyridostatin hydrochloride, 0.05-20 ng/μL, 5 nL) concentration at 24 hpf (d) and 48 hpf (e).

     qRT-PCR measurement of shox. The mRNA expression level of the shoxgene was detected at different time points (3, 7, and 14 days post-fertilization; i.e., 3 dpf, 7 dpf, and 14 dpf). The results showed that, compared with wild-type zebrafish, the G4 stabilizer Pyridostatin hydrochloride (0.05-0.1 ng/μL) significantly reduced the shox mRNA expression level in wrn−/− zebrafish.

     Levels of miR-26a in MPHs transfected with miR-26a-WT or miR-26a-G4mut plasmids and stimulated with Pyridostatin hydrochloride (PDS, 10 μM; 48 h). The results showed that PDS significantly diminished the increase in miR-26a expression induced by miR-26a-WT plasmids, but not by miR-26a-G4mut plasmids, indicating that the G/A mutations are sufficient to abolish the inhibitory effect of PDS on miR-26a expression.

     Pyridostatin hydrochloride (PDS, 10 μM; 48 h) markedly inhibited insulin-induced AKT activation, a central hallmark of insulin sensitivity, in MPHs (isolated from C57BL/6 mice) transfected with miR-26a-WT plasmids.

    Customer Validation
     8- to 10-week-old mice were infused with Pyridostatin hydrochloride (PDS, 6 mg/kg body weight) or saline (NC) via caudal vein twice a day (n = 5). 12 h post the second injection, the following measurements were performed. Representative H&E staining of paraffin liver sections. Scale bars: 20 μm. The results showed that no significant differences in histology and morphology were observed between PDS-treated mice and saline-treated mice.
