Cat. No.: HY-15176A Purity: 98.53%
COA Handling Instructions

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

Description

Pyridostatin (RR82) hydrochloride is a G-quadruplex DNA stabilizing agent (Kd=490 nM). Pyridostatin hydrochloride promotes growth arrest in human cancer cells by inducing replication- and transcription-dependent DNA damage. Pyridostatin hydrochloride targets the proto-oncogene Src. Pyridostatin hydrochloride reduced SRC protein levels and SRC-dependent cellular motility in human breast cancer cells[1][2].

IC50 & Target

Kd: 490 nM (G-quadruplexe)[1]

In Vitro

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

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.
