Pyridostatin is a synthetic small-molecule stabilizer of G-quadruplexes, a secondary structure of DNA that usually exists in the end of the chromosome or the telomeres. It can compete for binding with the telomere-associated proteins and induce telomerase dysfunction. Pyridostatin induces DNA damage and cell cycle arrest (K = 490 nM) and has been shown to target the proto-oncogene Src, reducing Src protein abundance and Src-dependent motility in human breast cancer cells.
Pyridostatin (trifluoroacetate salt) is a G-quadruplex (G4) inducer/stabilizer with a Kd of 490 nM. Pyridostatin TFA also acts as an inhibitor of Zika virus (ZIKV) NS2B-NS3 protease, with an IC50 of 11.0 μM. Pyridostatin TFA interacts with G-quadruplex structures, regulates the expression of SRC and SUB1, and induces replication- and transcription-dependent DNA damage, growth arrest, and genomic instability. Pyridostatin TFA exhibits antiproliferative and antiviral activities. Pyridostatin TFA can be used in studies related to breast cancer, cervical cancer, and Zika virus infection.
