9,10-Bis[(4-(2-hydroxyethyl)piperazine-1-yl)prop2-yne-1-yl]anthracene: G-Quadruplex Selectivity and Anticancer...

G-Quadruplexes (G4s) are appealing targets for anticancer therapy because of their location in the genome and their role in regulating physiological and pathological processes. In this article, we report the characterization of the molecular interaction and selectivity of OAF89, a 9,10-disubstituted G4-binding anthracene derivative, with different DNA sequences. Advanced analytical methods, including mass spectrometry and nuclear magnetic resonance, were used to conduct the investigation, together with the use of in silico docking and molecular dynamics. Eventually, the compound was tested in vitro to assess its bioactivity against lung cancer cell lines.
