Pyridostatin TFA salt

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 406602

CAS#: 1472611-44-1 (TFA)

Description: Pyridostatin stabilizes G-quadruplexes (G4s) in cells and elicits a DNA damage response by causing the formation of DNA double strand breaks (DSB). Pyridostatin promotes growth arrest in human cancer cells by inducing replication- and transcription-dependent DNA damage. Pyridostatin targets gene bodies containing clusters of sequences with a propensity for G-quadruplex formation. As a result, pyridostatin modulated the expression of these genes, including the proto-oncogene SRC.
