Pyridostatin is a highly selective G-quadruplex-binding small molecule that was designed to target polymorphic G-quadruplex structures regardless of sequence variability. As a highly selective G-quadruplex DNA stabilizer,Kd is 490 nM. Pyridostatin has anti-proliferative effects and induces telomere dysfunction[1-4].
Pyridostatin(2 µM pyridostatin;24 h) induced DNA damage and checkpoint-dependent cell-cycle arrest in MRC-5 SV40 cells[5]. Pyridostatin(0.01-5 µM pyridostatin;24-96 h) induced neurotoxicity and promoted the formation of DNA double-strand breaks (DSBs) in cultured neurons[6]. Pyridostatin(10 µM pyridostatin;24 h) significantly downregulated 22 proteins but upregulated 16 proteins in HeLa cancer cells, of which the genes both contain a number of G4 potential sequences, Pyridostatin regulation on gene expression is far more complicated than inducing/stabilizing G4 structures[7].

Pyridostatin是一种高选择性的 G-quadruplex DNA 稳定剂 (Kd=490 nM),而不考虑序列可变性。Pyridostatin具有抗增殖作用并诱导端粒功能障碍[1-4]。
Pyridostatin(2 µM Pyridostatin;24 h)诱导MRC-5 SV40细胞DNA损伤和检查点依赖性细胞周期阻滞[5]。Pyridostatin(0.01-5 µM Pyridostatin;24-96 h)诱导神经毒性,促进培养神经元DNA双链断裂(DSBs)的形成[6]。Pyridostatin(10 µM Pyridostatin;24 h)在HeLa癌细胞中显著下调22个蛋白,上调16个蛋白,其中基因均含有多个G4潜在序列,Pyridostatin对基因表达的调控远比诱导/稳定G4结构复杂[7]。
