Abstract A new and never before reported hetero-arylidene-9(10H)-anthrone structure (4) was unexpectedly isolated on reaction of 1,2-dimethyl-3-ethylimidazolium iodide (2) and 9-anthracenecarboxaldehyde (3) under basic conditions. Its structure was unequivocally confirmed by X-ray crystallography. No cytotoxicity in human healthy fibroblasts and in two different cancer cell lines was observed, indicating its applicability in biological systems. Compound 4 interacts with CT-DNA by intercalation between the adjacent base pairs of DNA with a high binding affinity [K-b = 2.0(+/- 0.20)x10(5) m(-1)], which is 10x higher than that described for doxorubicin [K-b = 3.2(+/- 0.23)x10(4) m(-1)]. Furthermore, compound 4 quenches the fluorescence emission of a GelRed-CT-DNA system with a quenching constant (K-SV) of 3.3(+/- 0.3)x10(3) m(-1) calculated by the Stern-Volmer equation.
