Pyridostatin trihydrochloride is a potent G-quadruplex stabilizer with a binding affinity (Kd) of 490 nM, effectively targeting DNA and RNA G-quadruplex structures within cellular environments. This compound induces growth arrest in human cancer cells through mechanisms involving replication- and transcription-dependent DNA damage. Pyridostatin specifically impacts the proto-oncogene Src, leading to diminished SRC protein levels and reduced SRC-dependent cellular motility in human breast cancer cells. Its applications extend to cancer research, particularly in studying mechanisms of tumor progression and drug resistance.
