生物活性

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[1][2].

Pyridostatin (RR82) (10 μM; 48 hours) induces cell cycle arrest[1].
Pyridostatin is a very selective G-quadruplex DNA-binding small molecule designed to form a complex with and stabilize G-quadruplex structure. Pyridostatin causes neurite retraction, synaptic loss, and dose-dependent neuronal death. In cultured primary neurons, Pyridostatin induces the formation of DNA DSBs. Remarkably, Pyridostatin (1-5 μM, overnight) downregulates the BRCA1 protein, a protein that guards and repairs the neuronal genome, at the transcriptional level[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
