生化／生理作用
RHPS4 is a pentacyclic acridine compound that exerts telomerase inhibitory activity (IC50 = 330 nM by TRAP assay) via targeting telomeric DNA G-quadruplex (G4) structure, causing alteration in the telomeric architecture and telomere dysfunction. RHPS4 induces cell cycle arrest and growth inhibition in cancer cultures in vitro(% GI/culture/time = 93%/21NT/15 days, 67%/A431/12 days, 91%/GM847/15 days; 200 nM replenish twice weekly) and exhibits anti-tumor efficacy in mice in vivo (10-15 mg/kg/d iv.). RHPS4 is also reproted to target mitochondrial DNA (mtDNA) G4 structures, perturbing mitochondrial genome replication, transcription processivity, and respiratory function.

This study had two goals: 1) to evaluate the biological effect of the novel pentacyclic acridine 3,11-difluoro-6,8,13-trimethyl-8H-quino[4,3,2-kl]acridinium methosulfate (RHPS4) on human melanoma lines possessing long telomeres, and 2) to elucidate the relationship between G-quadruplex-based telomerase inhibitor-induced cellular effects and telomere

The formation of G-quadruplex structures at telomeric DNA sequences blocks telomerase activity, offering an original strategy to design and develop new antitumor agents. The pentacyclic acridinium salt RHPS4 is one of the most effective and selective G4 ligands able to

Functional telomeres are required for the replicability of cancer cells. The G-rich strand of telomeric DNA can fold into a 4-stranded structure known as the G-quadruplex (G4), whose stabilization alters telomere function limiting cancer cell growth. Therefore, the G4 ligand
