Biological Activity

[Description]:

Pyridostatin (RR82) TFA is a G-quadruplex DNA stabilizing agent (Kd=490 nM). Pyridostatin TFA promotes growth arrest in human cancer cells by inducing replication- and transcription-dependent DNA damage. Pyridostatin TFA targets the proto-oncogene Src. Pyridostatin TFA reduced SRC protein levels and SRC-dependent cellular motility in human breast cancer cells[1][2][3].

[In Vitro]

Pyridostatin (RR82) hydrochloride (10 μM; 48 hours) induces cell cycle arrest[1]. Pyridostatin TFA is a very selective G-quadruplex DNA-binding small molecule designed to form a complex with and stabilize G-quadruplex structure. Pyridostatin TFA causes neurite retraction, synaptic loss, and dose-dependent neuronal death. In cultured primary neurons, Pyridostatin TFA induces the formation of DNA DSBs. Remarkably, Pyridostatin TFA (1-5 μM, overnight) downregulates the BRCA1 protein, a protein that guards and repairs the neuronal genome, at the transcriptional level[3]. Cell Viability Assay[1] Cell Line: Over 60 different cancer cell lines Concentration: 10 μM Incubation Time: 48 hours Result: Predominantly accumulated in the G2 phase of the cell cycle over 60 different cancer cell lines.
